SCAPIS: Simple questionnaire can identify silent atherosclerosis
Individuals in the general population with high levels of silent coronary atherosclerosis can be successfully identified with a simple questionnaire that they can complete themselves at home, a new study suggests.
The Swedish CardioPulmonary BioImage Study (SCAPIS) found that 40% of middle-aged adults without known heart disease had evidence of coronary atherosclerosis on coronary CT angiography (CCTA), and 13% had extensive atherosclerotic disease.
The authors found that the screening questionnaire could identify individuals who had extensive coronary atherosclerosis with a reasonably high predictive value.
Initial results from the study were presented today at the virtual American Heart Association (AHA) Scientific Sessions 2020.
“Our study is looking to see if we can estimate how many people in the general population have significant coronary atherosclerosis and therefore could benefit from preventative treatment,” lead author, Göran Bergström, MD, explained to Medscape Medical News.
Bergström, who is professor and lead physician at Sahlgrenska Academy, Gothenburg University, Gothenburg, Sweden, said there are no good data on this as yet. “There are studies of atherosclerosis burden in patients who have had a cardiovascular event, but our study was conducted in a random selection of the middle-aged general population who did not have symptoms of heart disease.”
“Our study also suggests that in future we may be able to identify these people with an online questionnaire, and those that reached a certain score could be referred for an imaging test,” he added.
SCAPIS included more than 30,000 men and women, age 50 to 64 years, who had no history of cardiovascular events or cardiac intervention. They were asked questions about sex, age, lifestyle, smoking, body measurements, cholesterol medication, and blood pressure to predict their risk for coronary artery disease.
Researchers then used CCTA images to examine patients’ arteries for the presence of plaque. More than 25,000 individuals from the original sample were successfully imaged.
Results showed that 40% of the middle-aged population had some coronary atherosclerosis and 5% had severe atherosclerosis, defined as the presence of a stenosis blocking 50% or more of blood flow in one of the coronary arteries.
A second aim of the study was to use data from the questionnaire to develop a prediction model to identify people with widespread atherosclerosis — those with any type of stenosis in four different segments of their coronary arteries, who made up 13% of the population.
The questionnaire included data on 120 different variables. Of these variables, around 100 could be assessed by the patients themselves and another 20 measurements could be performed in the clinic, such as blood pressure and cholesterol levels.
The researchers then used artificial intelligence to assess which variables were associated with widespread atherosclerosis. This had an area under the curve (AUC, a measure of the predictive value) of 0.8.
“An AUC of 1.0 would show a perfect prediction, and a value of 0.5 shows no value. A result of 0.8 shows reasonable predictive potential. This is an encouraging result and suggests this strategy could work,” Bergström said.
“We know silent atherosclerosis is a big problem and causes sudden cardiac events in people who have not shown symptoms,” he said.
The goal is to identify these patients before they have an event and offer them preventive treatments. “At present we try and identify patients at high risk of cardiovascular events by using cholesterol and blood pressure measurements and cardiovascular risk scores such as Framingham. But this is not so effective,” Bergström explained.
“Using imaging such as CCTA, where you can actually see atherosclerotic plaque, could be better for prediction, but we can’t image everyone. So, we wanted to see whether we could narrow down the population who should receive imaging with a detailed questionnaire, and it looks like we can.”
The study found that including clinical measurements such as blood pressure and cholesterol did not add much to the predictive value for identifying people with extensive coronary atherosclerosis, a result that Bergström said was surprising.
Which population to target?
Discussant of the study, Pamela Douglas, MD, professor of research in cardiovascular diseases at Duke University, Durham, North Carolina, congratulated the SCAPIS investigators on creating “a very rich data set for current and future study.”
“The SCAPIS study has already yielded novel data on the prevalence of coronary artery disease in the general population, and will address many critical questions over the long term,” she said.
But Douglas suggested that individuals with extensive coronary atherosclerosis were not the most appropriate target population to identify.
“The rationale for choosing this cutpoint is unclear as clinical risk/mortality is higher in all nonobstructive coronary artery disease, starting at one-vessel involvement,” she noted. “Therefore, effective preventive strategies likely need to start with detection and treatment of patients with even minimal plaque.”
Responding to Medscape Medical News, Bergström said this was a valid argument. “We plan to reanalyze our results with different populations as the target — that is something that we can do in the future.
But targeting everyone with just one coronary plaque is going to identify a large group — it was 40% of the population in our study. This will be too many people in whom to perform confirmatory CCTA imaging. It would be impractical to try and conduct cardiac imaging on that many people.”
Bergström noted that more data are needed on the danger of various levels of coronary atherosclerosis in this population who have not had any symptoms.
“We don’t have this information at present, but we are continuing to follow our population and we will have data on cardiac events in a few years’ time. Then we will know which level of atherosclerosis we need to target. It will probably be somewhere in between the extensive levels we used in this first analysis (which occurred in 13% of people) and the 40% of people who showed just one area of plaque.”
This study is the first report from SCAPIS, a collaborative project between six Swedish universities with the following vision statement: to “reduce the risk of cardiovascular and respiratory diseases for generations to come.”
The SCAPIS project is funded by the Swedish Heart and Lung Foundation. Bergström reports no disclosures.

Clopidogrel bests ticagrelor head-to-head for elective PCI in ALPHEUS
Ticagrelor failed to unseat clopidogrel as the guideline-recommended P2Y12 inhibitor of choice in patients undergoing elective percutaneous coronary intervention for stable CAD in the randomized ALPHEUS trial.
“The higher level of platelet inhibition obtained with ticagrelor does not translate into a reduction of periprocedural MI or myocardial injury within 48 hours of high-risk PCI performed in stable coronary patients,” reported Johanne Silvain, MD, PhD, professor of cardiology at the Sorbonne University and director of the ICU at Pitie-Salpetriere Hospital, Paris, at the virtual American Heart Association scientific sessions.
Ticagrelor did, however, result in a significantly higher rate of nuisance or minor bleeding than clopidogrel within 30 days post PCI, as well as more frequent dyspnea and treatment discontinuation.
ALPHEUS was an open-label, randomized trial including 1,883 patients undergoing elective PCI for stable coronary disease at 49 French or Czech PCI centers. All participants were either troponin-negative or had a modestly elevated but declining high-sensitivity troponin level. They possessed an average of 3.2 procedure-related or patient-related high-risk features, among the most common of which were multivessel disease, long lesions requiring multiple stents, and diabetes. Patients were randomized to a 300- or 600-mg loading dose of clopidogrel (Kengreal) or 180 mg of ticagrelor (Brilinta) prior to PCI. Afterwards they continued on 90 mg of ticagrelor twice daily or 75 mg of clopidogrel once daily for 30 days. Everyone was also on aspirin.
Myonecrosis hypothesis falls flat
The primary endpoint was the occurrence of major myocardial injury, defined as a periprocedural troponin elevated greater than 5 times the upper limit of normal within 48 hours of PCI; type 4a MI, defined as major myocardial injury plus signs or symptoms of ischemia; or stent thrombosis.
The rates were closely similar: 35.5% with ticagrelor, 36.2% with clopidogrel. The bulk of events consisted of major myocardial injury, with an incidence of 26.7% in the ticagrelor group and 27.7% with clopidogrel. Stent thrombosis occurred in 0.3% of patients in each group. Type 4a MI occurred in 8.5% of the ticagrelor group and 8.2% of patients on clopidogrel.
The study hypothesis was that a substantial portion of periprocedural myonecrosis may be thrombotic in nature, and that a stronger P2Y12 inhibitor could reduce the occurrence of these mini-infarcts and thus provide patient benefit. But the hypothesis was not borne out.
“We don’t know if these events are a risk factor or just a marker of risk,” Dr. Silvain said.
There were no between-group differences in major bleeding events at 48 hours or 30 days. However, the rate of nuisance or minor bleeding at 30 days was 11.2% in the ticagrelor arm, significantly higher than the 7.5% incidence with clopidogrel. Moreover, dyspnea occurred in 11.2% of patients on ticagrelor, compared to 0.2% with clopidogrel. Study drug discontinuation was more frequent in the ticagrelor arm: 2.2%, versus 0.4%.
Dr. Silvain also presented a pooled analysis of the 1,883 patients in ALPHEUS plus 781 from the similarly designed SASSICAIA trial, which compared prasugrel (Effient) to clopidogrel. Neither of the more potent P2Y12 inhibitors showed superiority over clopidogrel.
Discussant Stephen D. Wiviott, MD, summed things up: “With no evidence for ischemic benefit and higher rates of low-severity bleeding, this trial does not support the use of more potent P2Y12 antagonists for elective PCI. Based on these results, and consistent with SASSICAIA, aspirin with clopidogrel should remain the standard of care in this population.”
Troponin response may vary
A striking finding in ALPHEUS was the discrepancy between very high rates of periprocedural troponin elevation and very low rates of clinical events through 30 days of follow-up. “When you look at these modest elevations of troponin it appears that there is a lot of noise here,” said Dr. Wiviott, vice president for clinical trials research and administration at Massachusetts General Hospital and Brigham and Women’s Hospital and a cardiologist at Harvard Medical School, Boston.
Troponin elevations in stable coronary patients undergoing PCI may have a different underlying mechanism than elevated troponins in patients undergoing PCI for an acute coronary syndrome, he added. In stable CAD patients, the phenomenon may be more related to atherosclerosis than to platelet activation and thrombosis.
During a panel discussion, Sunil V. Rao, MD, said cardiologists are “probably going to have to go back to the drawing board and think about what kinds of events are really, really important.”
“It’s incumbent on our profession to figure out whether periprocedural MI should continue to be a component of the composite endpoint in PCI trials, because it’s highly dependent on the definition that’s being used,” observed Dr. Rao, professor of medicine at Duke University, Durham, N.C.
Dr. Silvain reported receiving institutional research funding and consulting fees from AstraZeneca, which funded the ALPHEUS trial. He serves as a consultant to a handful of other pharmaceutical companies as well.
Simultaneously with Dr. Silvain’s presentation at AHA 2020, the ALPHEUS results were published online in The Lancet.

REPORTING FROM AHA 2020
TIPS-3: Polypill provides meaningful primary cardiovascular prevention
A once-daily polypill containing four drugs to lower blood pressure and LDL cholesterol reduced major adverse cardiovascular events by 21% relative to placebo in people at intermediate cardiovascular risk in the landmark TIPS-3 trial.
And with the addition of aspirin at 75 mg per day the combination achieved an even more robust 31% relative risk reduction, investigators reported at the.
“Aspirin contributes importantly to the benefits,” Salim Yusuf, MD, DPhil, emphasized in presenting the International Polycap Study (TIPS-3) results jointly with study coprincipal investigator Prem Pais, MD, at the virtual American Heart Association scientific sessions.
The multinational study provides powerful new support for a broad, population health–based approach to primary cardiovascular prevention.
“If half of eligible people [were to] use a polypill with aspirin, 3-5 million cardiovascular events per year would be avoided globally,” according to Dr. Yusuf, professor of medicine and director of the Population Health Research Institute at McMaster University in Hamilton, Ont.
“This is likely a cost-effective strategy to meet global targets of reducing cardiovascular disease by 30% by 2020,” added Dr. Pais of St. John’s Research Institute in Bangalore, India.
TIPS-3 included 5,713 participants at intermediate cardiovascular risk, with an estimated event risk of 1.8% per year using the INTERHEART Risk Score. Half were women. More than 80% of participants had hypertension, and nearly 40% had diabetes or impaired fasting glucose. Nearly 90% of participants came from India, the Philippines, Malaysia, Indonesia, or Bangladesh. All participants received advice about lifestyle management.
They were then randomized to receive a polypill or placebo, and then each group was further randomized to receive 75 mg/day of aspirin or matching placebo. The polypill contained 40 mg of simvastatin, 100 mg of atenolol, 25 mg of hydrochlorothiazide, and 10 mg of ramipril.
During a mean 4.6 years of follow-up, the primary composite major adverse cardiovascular event rate occurred in 4.4% of the polypill group, 4.1% of the polypill-plus-aspirin group, and 5.8% of the double-placebo group. This translated to a 21% reduction in cardiovascular disease with the polypill, a 31% reduction with polypill plus aspirin, and a 14% reduction in the composite of cardiovascular death, MI, or stroke with aspirin alone.
The polypill and placebo groups diverged in terms of the primary outcome starting about 6 months into the study, Dr. Pais noted.
Serious adverse events were less common with the polypill than with placebo. Importantly, there was no difference in major, minor, or GI bleeding between the polypill-plus-aspirin group and placebo-treated controls. Dr. Yusuf attributed the lack of excess bleeding in aspirin recipients to two factors: people with a history of bleeding or GI symptoms were excluded from TIPS-3, and the dose of aspirin used was lower than in other primary prevention trials, where bleeding offset the reduction in cardiovascular events.
Nonadherence was a major issue in TIPS-3, mainly because of delays in polypill production and distribution, coupled late in the trial with the COVID-19 pandemic. The nonadherence rate was 19% at 2 years, 32% at 4 years, and 43% at the study’s end. Only 5% of discontinuations were due to side effects. In a sensitivity analysis carried out in participants without discontinuation for nonmedical reasons, the benefits of the polypill plus aspirin were larger than in the overall study: a 39% relative risk reduction in the primary endpoint that probably offers a more accurate picture of the combination’s likely real-world performance.
Discussant Anushka Patel, MBBS, PhD, noted that TIPS-3 is the third randomized trial to provide direct evidence that a polypill-based strategy improves clinical outcomes. The effect sizes of the benefits – a 20%-30% reduction in major cardiovascular events – has been consistent in TIPS-3, PolyIran, and HOPE-3, each of which tested a different polypill drug combination.
“If implementation and adherence challenges can be addressed at the system, prescriber, and patient levels, and if high-quality polypills can be made affordable, the public health impact could actually be enormous,” said Dr. Patel, chief scientist at the George Institute for Global Health and professor of medicine at the University of New South Wales in Sydney, Australia.
However, she parted company with Dr. Yusuf regarding routine incorporation of aspirin into polypills.
“I think the totality of evidence would still probably favor taking an individualized approach that also considers bleeding risk,” the cardiologist said.
Donald Lloyd-Jones, MD, who chaired a press conference highlighting TIPS-3, declared, “You’re seeing a paradigm shift right here in front of your eyes today. This could be a game changer in terms of preventing large numbers of cardiovascular events.”
While TIPS-3 was conducted mainly in low- and middle-income countries, it’s important to recognize that’s where 75% of cardiovascular events and cardiovascular deaths now occur.
“This is very much a disease that has emerged in the developing world,” commented Dr. Lloyd-Jones, the AHA president-elect, chair of the AHA Council on Scientific Sessions Programming, and professor and chair of the department of preventive medicine at Northwestern University, Chicago.
He also sees a polypill strategy for primary cardiovascular prevention as highly viable in high-resource countries. It makes sense to employ it there initially in underserved communities, where a polypill-based approach sidesteps difficulties in monitoring care and adjusting medication doses due to reduced access to health care while minimizing cost and adherence issues, he added.
Dr. Yusuf and Dr. Pais reported receiving institutional research support from the TIPS-3 major sponsors: the Wellcome Trust, Cadila Pharmaceuticals, the Canadian Institutes of Health Research, and the Heart and Stroke Foundation of Canada.
Simultaneously with their presentation at AHA 2020, the TIPS-3 results were published online in the New England Journal of Medicine.

Don’t miss cardiovascular risk factors in transgender patients
Cardiovascular disease risk is elevated among transgender individuals seeking gender-affirming hormone therapy, according to a retrospective study in 427 patients.
The transgender population often experiences socioeconomic and health disparities, including reduced access to care, Kara J. Denby, MD, said in an interview.
Previous research suggests that the use of gender-affirming hormone therapy (GAHT) may place transgender persons at increased cardiovascular risk, she said.
To identify the potential risk for transgender individuals, the researchers identified baseline cardiovascular risk in patients who had not yet undergone GAHT. Study participants were enrolled in a multidisciplinary transgender program, and the researchers collected data on demographics, medical history, vitals, medications, and laboratory results. The average age of the participants was 26 years, 172 identified as men, 236 as women, and 20 as nonbinary.
Overall, 55% of the participants had a chronic medical condition at baseline. Of these, 74 patients had hypertension, 41 had hyperlipidemia, 2 had a history of stroke, 7 had coronary artery disease, and 4 had chronic obstructive pulmonary disease.
For all patients who did not have documented atherosclerotic cardiovascular disease, their American College of Cardiology/American Heart Association ASCVD and QRISK3 risk scores were calculated. “The incidence of undiagnosed hypertension and hyperlipidemia was 6.8% and 11.3% respectively, and of these cases, only 64% and 24% were on appropriate therapies,” noted Dr. Denby of the Cleveland (Ohio) Clinic.
She reported the results Nov. 13 in a presentation at the at the virtual American Heart Association scientific sessions.
The findings were limited by the observational nature of the study.
However, the results suggest that transgender patients “appear to be at higher risk than their age-matched historical cohorts regardless of gender,” said Dr. Denby. More research is needed, but cardiovascular disease–prevention efforts may be inadequate in the transgender population given the elevated risk observed in this study, she concluded.
Growing transgender population is medically underserved
The transgender population is growing in the United States and internationally, said Dr. Denby. “This group has a history of being marginalized as a result of their transgender status with socioeconomic and health repercussions,” she said. “It is well known that transgender patients are less likely to have access to health care or utilize health care for a variety of reasons, including stigma and fear of mistreatment. This often leads transgender individuals to present to care late in disease processes which makes their disease harder to treat and often leads to emergent medical conditions,” she added.
“Transgender men and women are at high risk for cardiovascular disease and often aren’t screened at recommended intervals because of decreased health care use compared to their cisgender counterparts,” she said. “This may lead to untreated diseases that make them even more likely to suffer poor health outcomes.”
The current study is important because there are “almost no prior data regarding the cardiovascular health status of this population prior to gender-affirming care,” Dr. Denby emphasized. “There are data that gay, lesbian, and bisexual individuals are at higher risk for poor cardiovascular outcomes, but the same data are lacking in the transgender group,” she said.
“As transgender individuals have frequent physician visits while on hormonal therapy, this seems like the opportune time to screen for cardiovascular risk factors and treat previously undiagnosed diseases that can lead to poor health outcomes in the future,” Dr. Denby explained. “If we are able to intervene at an earlier age, perhaps we can help prevent poor health outcomes down the road,” she said.
Additional research can inform practice
Dr. Denby said she was not surprised by the findings. “This is a very high-risk population that often doesn’t follow closely in the health care system,” she said. “These data are very important in thinking holistically about transgender patients.” Clinicians can “use the opportunities we have when they present for gender-affirming care to optimize their overall health status, promote long-term health, and reduce the risks associated with hormonal therapy and gender-affirming surgeries,” she noted. “We hope to use this information to change our practice at the Cleveland Clinic and nationally as well. Transgender patients should be screened and aggressively treated for cardiovascular disease and risk factors,” she said.
Key barriers to overcome include determining the best way to reach out to transgender individuals and then making them feel comfortable in the clinical setting, Dr. Denby said. “This means that we must set up clinics that are approachable and safe for all comers. The lack of laws in many states that protect this vulnerable population also contributes to lack of access to care,” she added.
“We hope to continue research in this arena about how to effectively screen and treat transgender patients as they present to care, not only in the transgender clinic, but also to primary care providers (ob.gyn., internal medicine, family medicine, pediatrics) who also care for this population” since no specific guidelines currently exist to direct the screening for cardiovascular patients in particular, she said.
Findings offer foundation for LGBTQ cardiovascular studies
“This [study] provides us with a good rationale for why we should be considering cardiovascular health in transgender adults,” Billy A. Caceres, PhD, RN, of Columbia University School of Nursing, New York, said in an interview. “It is largely descriptive, but I think that that’s a good step in terms of at least understanding the magnitude of this problem. In addition, I think that what this abstract might do is help lead to future research that examines potentially the associations between not only gender-affirming hormone therapies but other potential social determinants like discrimination or poverty on the cardiovascular health of transgender people,” he noted.
Dr. Caceres served as chair of the writing group for the recent American Heart Association Scientific Statement: LGBTQ Heart Health published in Circulation. He had no financial conflicts to disclose.
The study received no outside funding. Dr. Denby had no financial conflicts to disclose.

Virtual AHA 2020 may influence template for postpandemic scientific sessions
Cardiologists are already old hands at virtual meetings this year and are fast becoming experts on Zoom and other teleconferencing platforms, if not on how to unmute their microphones.
With expectations perhaps elevated and the new communications genre’s novelty on the wane, the American Heart Association (AHA) Scientific Sessions 2020 has a chance to both innovate with familiar formats and captivate with the field’s latest research findings.
Although the virtual AHA 2020 might not satisfy longings for face-to-face networking, shop talk, or kidding around over coffee, it will feature many traditional elements of the live conferences adapted for ear buds and small screens. They include late-breaking science (LBS) presentations and panel discussions, poster and live oral abstract presentations, meet-the-trialist talks, fireside-chat discussion forums, early career events, and satellite symposia.
The event may well hold lessons for future iterations of AHA Scientific Sessions in the postpandemic world, which some foresee as, potentially, an amalgam of the time-honored live format and a robust, complementary online presence.
“I can’t commit to exactly what AHA sessions will look like next November; I think that’s still being looked at,” the organization’s president-elect Donald M. Lloyd-Jones, MD, ScM, chair of the AHA Committee on Scientific Sessions Programming, told theheart.org | Medscape Cardiology.
There’s no debating that a live conference is valuable “for career networking and other opportunities, so I don’t think we can do without it. That has to be an important part of it,” he said. “When we can safely, of course.”
Still, “the virtual platform democratizes, right? I mean, it just allows greater access for a broader audience, and I think that’s important, too,” said Lloyd-Jones, MD, Northwestern University Feinberg School of Medicine, Chicago.
“I don’t think we’ll ever go completely back to it being all in-person,” he said. “I think the world has changed, and we’ll have to adapt our platforms to recognize that.”
Online, at least, meeting registrants will get a better look at Anthony Fauci, MD, than one might from the middle rows of a vast ballroom-turned-auditorium. Fauci is scheduled to speak on “Public Health and Scientific Challenges” during the Main Event Session “Latest Insights on COVID 19 and Cardiovascular Disease,” slated for the meeting’s final day.
Fauci has directed the National Institute of Allergy and Infectious Diseases (NIAID) since 1984, and has been celebrated for his leadership roles in the battles against AIDS and Ebola virus. Today, his name is close to a household word for his service as a prominent though embattled member of the White House Coronavirus Task Force.
The virtual AHA sessions will feature a core collection of LBS presentations from often high-profile clinical trials and other studies the organization deems worthy of special attention. There are nine such presentations arrayed across the meeting’s five days — from Friday, November 13 to Tuesday, November 17 — at times listed in this story and throughout the AHA Scientific Session program synched with the Central Standard Time (CST) zone of the AHA’s home office in Dallas.
Late-Breaking Science 1. Friday, November 13, 10:30 AM - 11:30 AM CST
The LBS sessions launch with the GALACTIC-HF trial, which — the world recently learned — may expand the burgeoning list of meds shown to improve clinical outcomes in chronic heart failure (HF) with reduced ejection fraction (HFrEF).
In cursory top-line results announced last month, those in the trial of more than 8000 patients who were randomly assigned to receive omecamtiv mecarbil (Amgen/Cytokinetics/Servier) showed a slight but significant benefit for the primary end point of cardiovascular (CV) death or HF events. The hazard ratio (HR), compared with standard care, was 0.92 (95% CI, 0.86 - 0.99; P = .025), noted a press release from Amgen.
Among the announcement’s few other details was a short take on safety outcomes: no difference in risk for “adverse events, including major ischemic cardiac events,” between the active and control groups. The presentation is sure to provide further insights and caveats, if any, along with other information crucial to the study’s interpretation.
Next on the schedule is the closely watched AFFIRM-AHF, billed as the first major outcomes trial of iron administration to iron-deficient patients with acute HF. It randomly assigned more than 1000 such patients to receive IV ferric carboxymaltose or a placebo. The first dose was given in-hospital and subsequent doses at home for 24 weeks or until patients were no longer iron deficient. They were followed to 1 year for the primary end point of recurrent HF hospitalizations or CV death.
The session wraps with the VITAL Rhythm trial, a substudy of the doubly randomized VITAL trial that explored the effects of vitamin D and omega-3 fatty acid supplementation on CV and cancer risk in more than 25,000 patients in the community. The substudy explored the effects of two active therapies, a preparation of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Omacor, Reliant Pharmaceuticals) or vitamin D3 supplements, on new-onset atrial fibrillation (AF) as the primary end point; it also looked at risk for sudden death.
Late-Breaking Science 2. Friday, November 13, 12:00 PM - 1:00 PM CST
Dominating the session in two presentations, the (TIPS)-3 trial explored a polypill primary-prevention strategy and daily aspirin with vitamin D supplementation in three separate placebo-controlled comparisons in more than 5700 “intermediate risk” participants 55 years and older, mostly in developing countries.
The daily polypill in this trial is a combination of hydrochlorothiazide 25 mg, atenolol 100 mg, ramipril 10 mg, and simvastatin 40 mg; aspirin was given at 75 mg daily and vitamin D at 60,000 IU monthly.
The participants are followed for a primary end point composed of major CV disease, HF, resuscitated cardiac arrest, or ischemia-driven revascularization for the polypill comparison; CV events or cancer for the aspirin comparison; and fracture risk for the vitamin D component of the trial.
In the Swedish Cardiopulmonary Bioimage Study (SCAPIS), presented third in the session, a random sample of adults from throughout Sweden, projected at about 30,000, underwent a 2-day evaluation for metabolic risk factors plus ultrasound and coronary and lung CT scans. The group has been followed for risks for myocardial infarction (MI), sudden death, and other cardiac diseases; and chronic obstructive pulmonary disease (COPD) and other lung disorders.
Late-Breaking Science 3. Saturday, November 14, 12:00 PM - 1:00 PM CST
The field may learn more mechanistically about MI associated with nonobstructed coronary arteries (MINOCA) than ever before from the Heart Attack Research Program-Imaging Study (HARP). The observational study is enrolling a projected 450 patients with suspected MI and ischemic symptoms who were referred for cardiac catheterization.
Their evaluation includes coronary optical coherence tomographic (OCT) scanning and cardiac magnetic resonance (CMR) imaging for evidence of coronary plaque disruption as the primary end point. The patients are to be followed for 10 years for a composite of death, unstable angina, stroke, recurrent MI, diagnostic or interventional catheterization, and cardiac hospitalization.
The major direct oral anticoagulant (DOAC) comparisons with warfarin in atrial fibrillation (AF) didn’t include many patients with prosthetic valve implants. In contrast, the RIVER trial enrolled 1005 adults with either persistent or paroxysmal AF and bioprosthetic mitral valves and assigned them to rivaroxaban 20 mg or the vitamin K antagonist.
The presentation will include the noninferiority primary outcome of major clinical events, which is stroke, transient ischemic attack (TIA), major bleeding, death from any cause, valve thrombosis, other systemic embolism, or HF hospitalization over 12 months.
This session also includes ALPHEUS, a trial pitting ticagrelor (Brilinta/Brilique, AstraZeneca) against mainstay clopidogrel in a setting that is mostly uncharted for such comparisons, elective percutaneous coronary intervention (PCI).
About 1900 patients with stable coronary disease were randomly assigned to a month of treatment with either agent on top of continuous aspirin. The primary end point is PCI-related MI or myocardial injury within 48 hours of the procedure.
Late-Breaking Science 4. Sunday, November 15, 9:00 AM - 10:00 AM CST
The Self-Assessment Method for Statin Side-effects Or Nocebo (SAMSON) trial may be one of the AHA 2020 frontrunners for early buzz and anticipation. So it’s with some irony that it’s also among the smallest of the LBS studies, at 60 patients, which was nonetheless considered sufficient due to its unusual design.
SAMSON is the latest and perhaps most rigorous attempt to clarify whether symptoms, especially muscle pain or discomfort, attributed to statins by many patients are pharmacologic in origin or, rather, a nocebo effect from negative expectations about statin side effects.
The study patients, all of whom had previously halted statins because of side effects, were assigned to follow three separate regimens, each for month, in a randomized order; they did that four times, for a total of 12 months. The regimens consisted of atorvastatin 20 mg daily, a placebo, or neither.
Patients kept daily logs of any perceived side effects. Parity between side effects experienced on the statin and the placebo would point to a nocebo effect, whereas a significant excess on atorvastatin would suggest they are direct drug effects.
The session also features two randomized trials each on a unique omega-3 fatty acid preparation for either secondary prevention or high-risk primary prevention, in both cases compared with a corn-oil placebo.
The Omega-3 Fatty Acids in Elderly Patients with Myocardial Infarction (OMEMI) trial randomly assigned more than 1000 elderly post-MI patients to take Pikasol (Orkla Care) at 1.8 g EPA and DHA per day or the placebo. It looked for all-cause mortality, nonfatal MI, stroke, revascularization, or hospitalization for new or worsened HF over 24 months.
The STRENGTH trial, with a planned enrollment of about 13,000 high-vascular-risk patients, looked primarily at the effect of daily treatment with Epanova (AstraZeneca), which also contains DHA and EPA, on the composite of CV death, nonfatal MI or stroke, coronary revascularization, and hospitalization for unstable angina. The trial was halted early for low likelihood of benefit, AstraZeneca announced in January of this year.
Late-Breaking Science 5. Sunday, November 15, 7:15 PM - 8:30 PM CST
Slated for the session is the primary analysis of the PIONEER 3 trial, conducted in the United States, Europe, and Japan. It compared the BuMA Supreme biodegradable drug-coated stent (SinoMed) with the durable Xience (Abbott Vascular) and Promus (Boston Scientific) drug-eluting stents. The trial followed more than 1600 patients treated for chronic stable angina or acute coronary syndrome (ACS) for the 1-year composite of cardiac death, target-vessel-related MI, and clinically driven target-lesion revascularization.
Late-Breaking Science 6. Monday, November 16, 9:00 AM - 10:00 AM CST
The EARLY-AF trial enrolled 303 patients with symptomatic paroxysmal or persistent AF suitable for catheter ablation, assigning them to pulmonary vein isolation (PVI) by cryoablation using the Arctic Front (Medtronic) system or antiarrhythmic drug therapy for rhythm control. The primary end point is time to recurrence of AF, atrial flutter, or atrial tachycardia, whether symptomatic or asymptomatic, as determined by implantable loop recorder. Patients will also be followed for symptoms and arrhythmia burden.
Also in the session, the SEARCH-AF study randomized almost 400 patients undergoing cardiac surgery who were engaged subacutely with one of two commercial portable cardiac rhythm monitoring devices (CardioSTAT, Icentia; or SEEQ, Medtronic) or, alternatively, to receive usual postoperative care
The patients, considered to be at high risk for stroke with no history of AF, were followed for the primary end point of cumulative burden of AF or atrial flutter exceeding 6 minutes or documentation of either arrhythmia by 12-lead ECG within 30 days.
Two other studies in the session look at different approaches to AF screening, one using a handheld ECG monitor in the primary care setting and the other wearable monitors in the form of a patch or wristband. The VITAL-AF presentation is titled “Screening for Atrial Fibrillation in Older Adults at Primary Care Visits Using Single Lead Electrocardiograms.” The other presentation, on the study mSToPS, is called “Three-Year Clinical Outcomes in a Nationwide, Randomized, Pragmatic Clinical Trial of Atrial Fibrillation Screening — Mhealth Screening to Prevent Strokes.”
Late-Breaking Science 7. Monday, November 16, 7:00 PM - 8:30 PM CST
In the randomized FIDELIO-DKD trial with more than 5700 patients with type 2 diabetes and associated kidney disease, those assigned to the novel mineralocorticoid receptor antagonist (MRA) finerenone (Bayer) showed an 18% drop in risk for adverse renal events, including death from renal causes (P = .001), over a median of 2.6 years. That primary outcome was previously presented in detail at a nephrology meeting and published in the New England Journal of Medicine in October.
Patients on the MRA showed a similar reduction in a composite CV-event end point, it was also reported at that time. A follow-up presentation at the AHA sessions promises to dive deeper into the trial’s CV outcomes.
In the RAPID-CTCA study, slated next for the session, 1749 patients with suspected or confirmed intermediate-risk ACS were randomly assigned to undergo computed tomographic coronary angiography (CTCA) for guiding treatment decisions or a standard-of-care strategy. It followed patients for the primary end point of death or nonfatal MI over 1 year.
Rilonacept (Arcalyst, Kiniksa/Regeneron) is an interleukin-1α and -1β inhibitor used in several autoinflammatory diseases that went unsuccessfully before regulators for the treatment of gout. The RHAPSODY trial has now explored its use against recurrent pericarditis in a randomized trial that entered 86 patients 12 years and older who had previously experienced at least three episodes.
In top-line results reported to investors in June, patients assigned to receive the drug instead of placebo in weekly injections showed a 96% drop in risk for pericarditis recurrence and “no or minimal pain” on more than 90% of days in the trial. A full presentation is expected during this LBS session.
Also on the schedule is the THALES study, which led the US Food and Drug Administration (FDA) to expand indications for ticagrelor to include stroke prevention in patients with a history of acute ischemic stroke or high-risk TIA based on the trial’s primary results published in July.
In THALES, more than 11,000 patients with mild to moderate acute noncardiogenic ischemic stroke or TIA were randomly assigned within 24 hours to start on daily aspirin with or without ticagrelor given as a 180 mg loading dose followed by 90 mg twice daily for 30 days.
At the end of a month, it was reported, those on dual antiplatelet therapy showed a 17% risk reduction (P = .02) for the primary end point of stroke or death, at the cost of a slight but significant increase in “severe” bleeding (0.5% vs 0.1%; P = .001).
The session is to conclude with two related studies that fell victim in part to the COVID-19 pandemic, both of which explored sotagliflozin (Zynquista, Sanofi/Lexicon), an inhibitor of both sodium-glucose cotransporters 1 and 2 (SGLT1 and SGLT2, respectively) in patients with type 2 diabetes.
SOLOIST-WHF had entered 1222 such patients hospitalized with urgent or worsening HF at 466 centers and randomly assigned them to receive sotagliflozin or placebo; they were followed for the composite of CV death or HF events. SCORED reached an enrollment of 10,584 patients with diabetes and chronic kidney disease at 754 hospitals, following them for the same primary end point.
Lexicon announced in March that the trials would be “closed out early” because of the unavailability of funding “together with uncertainties relating to the COVID-19 pandemic on the trials.” The LBS presentation is expected to include analyses of available data; SOLOIST-WHF launched in summer 2018 and SCORED began in November 2017.
Late-Breaking Science 8. Tuesday, November 17, 9:00 AM - 10:00 AM CST
Most of this LBS session is devoted to the AHA COVID-19 Cardiovascular Disease registry, which is looking at the hospital journey, clinical course, and outcomes of patients hospitalized with SARS-CoV-2 infections at centers participating in the organization’s Get With The Guidelines (GWTG) quality-improvement program. As of September, the registry included data from more than 15,000 patients.
Scheduled presentations include a summary of the registry’s design and initial results; an analysis of racial and ethnic variation in therapy and clinical outcomes; an exploration of how body mass index influenced outcomes, including death, use of mechanical ventilation, and cardiovascular end points, in patients with COVID-19; and a deep dive into the relation between CV disease and clinical outcomes in the cohort.
The last of this LBS block’s five talks will cover the randomized Influenza Vaccine to Effectively Stop Cardio Thoracic Events and Decompensated Heart Failure (INVESTED) trial, which compared vaccination with high-dose trivalent influenza vaccine or a standard-dose quadrivalent vaccine in 5388 adults with a history of hospitalization for either MI or HF. Patients were required to have at least one other CV risk factor, such as older age, reduced left ventricular ejection fraction, or diabetes.
INVESTED tracked the patients at 190 centers across an initial pilot flu season and three subsequent flu seasons for the primary end point of death from any cause or cardiopulmonary hospitalization.
The trial is one of at least three that have been looking at the effect of flu vaccination on cardiovascular outcomes; results from the other two — IAMI, with more than 2500 participants, and RCT-IVVE, with an enrollment of 4871 — are planned for presentation in 2021, theheart.org | Medscape Cardiology recently reported.
Late-Breaking Science 9. Tuesday, November 17, 12:00 PM - 1:00 PM CST
The conference’s concluding LBS session features three studies that relied on technologic strategies for modifying patient compliance and other care behaviors and one that used human-centered design principles to develop a group-care model aimed improving the management of diabetes, hypertension, and other noncommunicable diseases in economically disadvantaged regions of Kenya.
The EPIC-HF trial tested a strategy for improving HFrEF medication-plan engagement by use of a video and documents delivered to patients several times by email or text prior to their follow-up clinic appointments. The strategy was compared with usual care for its effect on HF-medication optimization over 1 month and 1 year in a total of 306 patients.
Following EPIC-HF on the schedule is the MYROAD trial, looking at the efficacy of discharge instructions provided to patients with acute HF as an audio recording that they and their physicians could replay on demand, the idea being to increase adherence to the instructions. The trial’s 1073 patients were assigned to the novel strategy or usual care and followed for HF rehospitalization within 30 days.
MYROAD is to be followed by a presentation entitled “Digital Care Transformation: One-Year Report of >5,000 Patients Enrolled in a Remote Algorithm-Based CV Risk Management Program to Achieve Optimal Lipid and Hypertension Control.”
Rounding out the LBS session: the Bridging Income Generation With Group Integrated Care (BIGPIC) program, a pilot study that developed and executed “a healthcare delivery model targeting health behaviors, medication adherence, and financial barriers to accessing healthcare” in four rural counties in Kenya.
The model features locally developed plans, tailored for regional needs, that are said to “combine the benefits of microfinance with the peer support available through group medical care to enhance management of hypertension and diabetes.” The microfinance component is aimed at improving household economies to alleviate the financial burden of care and clinic attendance, and for the health effects of improved quality of life.
The study randomized 2890 adults with diabetes or prediabetes to one of four groups: usual care plus microfinance group support, group medical visits only or combined with microfinance group support, or usual care only. They were followed for changes in systolic blood pressure and CV-risk score over 12 months.
Lloyd-Jones and Fauci declared no conflicts.

In top-line results reported to investors in June, patients assigned to receive the drug instead of placebo in weekly injections showed a 96% drop in risk for pericarditis recurrence and “no or minimal pain” on more than 90% of days in the trial. A full presentation is expected during this LBS session.
Also on the schedule is the THALES study, which led the US Food and Drug Administration (FDA) to expand indications for ticagrelor to include stroke prevention in patients with a history of acute ischemic stroke or high-risk TIA based on the trial’s primary results published in July.
In THALES, more than 11,000 patients with mild to moderate acute noncardiogenic ischemic stroke or TIA were randomly assigned within 24 hours to start on daily aspirin with or without ticagrelor given as a 180 mg loading dose followed by 90 mg twice daily for 30 days.
At the end of a month, it was reported, those on dual antiplatelet therapy showed a 17% risk reduction (P = .02) for the primary end point of stroke or death, at the cost of a slight but significant increase in “severe” bleeding (0.5% vs 0.1%; P = .001).
The session is to conclude with two related studies that fell victim in part to the COVID-19 pandemic, both of which explored sotagliflozin (Zynquista, Sanofi/Lexicon), an inhibitor of both sodium-glucose cotransporters 1 and 2 (SGLT1 and SGLT2, respectively) in patients with type 2 diabetes.
SOLOIST-WHF had entered 1222 such patients hospitalized with urgent or worsening HF at 466 centers and randomly assigned them to receive sotagliflozin or placebo; they were followed for the composite of CV death or HF events. SCORED reached an enrollment of 10,584 patients with diabetes and chronic kidney disease at 754 hospitals, following them for the same primary end point.
Lexicon announced in March that the trials would be “closed out early” because of the unavailability of funding “together with uncertainties relating to the COVID-19 pandemic on the trials.” The LBS presentation is expected to include analyses of available data; SOLOIST-WHF launched in summer 2018 and SCORED began in November 2017.

Most of this LBS session is devoted to the AHA COVID-19 Cardiovascular Disease registry, which is looking at the hospital journey, clinical course, and outcomes of patients hospitalized with SARS-CoV-2 infections at centers participating in the organization’s Get With The Guidelines (GWTG) quality-improvement program. As of September, the registry included data from more than 15,000 patients.
Scheduled presentations include a summary of the registry’s design and initial results; an analysis of racial and ethnic variation in therapy and clinical outcomes; an exploration of how body mass index influenced outcomes, including death, use of mechanical ventilation, and cardiovascular end points, in patients with COVID-19; and a deep dive into the relation between CV disease and clinical outcomes in the cohort.
The last of this LBS block’s five talks will cover the randomized Influenza Vaccine to Effectively Stop Cardio Thoracic Events and Decompensated Heart Failure (INVESTED) trial, which compared vaccination with high-dose trivalent influenza vaccine or a standard-dose quadrivalent vaccine in 5388 adults with a history of hospitalization for either MI or HF. Patients were required to have at least one other CV risk factor, such as older age, reduced left ventricular ejection fraction, or diabetes.
INVESTED tracked the patients at 190 centers across an initial pilot flu season and three subsequent flu seasons for the primary end point of death from any cause or cardiopulmonary hospitalization.
The trial is one of at least three that have been looking at the effect of flu vaccination on cardiovascular outcomes; results from the other two — IAMI, with more than 2500 participants, and RCT-IVVE, with an enrollment of 4871 — are planned for presentation in 2021, theheart.org | Medscape Cardiology recently reported.
Late-Breaking Science 9. Tuesday, November 17, 12:00 PM - 1:00 PM CST
The conference’s concluding LBS session features three studies that relied on technologic strategies for modifying patient compliance and other care behaviors and one that used human-centered design principles to develop a group-care model aimed improving the management of diabetes, hypertension, and other noncommunicable diseases in economically disadvantaged regions of Kenya.
The EPIC-HF trial tested a strategy for improving HFrEF medication-plan engagement by use of a video and documents delivered to patients several times by email or text prior to their follow-up clinic appointments. The strategy was compared with usual care for its effect on HF-medication optimization over 1 month and 1 year in a total of 306 patients.
Following EPIC-HF on the schedule is the MYROAD trial, looking at the efficacy of discharge instructions provided to patients with acute HF as an audio recording that they and their physicians could replay on demand, the idea being to increase adherence to the instructions. The trial’s 1073 patients were assigned to the novel strategy or usual care and followed for HF rehospitalization within 30 days.
MYROAD is to be followed by a presentation entitled “Digital Care Transformation: One-Year Report of >5,000 Patients Enrolled in a Remote Algorithm-Based CV Risk Management Program to Achieve Optimal Lipid and Hypertension Control.”
Rounding out the LBS session: the Bridging Income Generation With Group Integrated Care (BIGPIC) program, a pilot study that developed and executed “a healthcare delivery model targeting health behaviors, medication adherence, and financial barriers to accessing healthcare” in four rural counties in Kenya.
The model features locally developed plans, tailored for regional needs, that are said to “combine the benefits of microfinance with the peer support available through group medical care to enhance management of hypertension and diabetes.” The microfinance component is aimed at improving household economies to alleviate the financial burden of care and clinic attendance, and for the health effects of improved quality of life.
The study randomized 2890 adults with diabetes or prediabetes to one of four groups: usual care plus microfinance group support, group medical visits only or combined with microfinance group support, or usual care only. They were followed for changes in systolic blood pressure and CV-risk score over 12 months.
Lloyd-Jones and Fauci declared no conflicts.

Cardiologists are already old hands at virtual meetings this year and are fast becoming experts on Zoom and other teleconferencing platforms, if not on how to unmute their microphones.
With expectations perhaps elevated and the new communications genre’s novelty on the wane, the American Heart Association (AHA) Scientific Sessions 2020 has a chance to both innovate with familiar formats and captivate with the field’s latest research findings.
Although the virtual AHA 2020 might not satisfy longings for face-to-face networking, shop talk, or kidding around over coffee, it will feature many traditional elements of the live conferences adapted for ear buds and small screens. They include late-breaking science (LBS) presentations and panel discussions, poster and live oral abstract presentations, meet-the-trialist talks, fireside-chat discussion forums, early career events, and satellite symposia.
The event may well hold lessons for future iterations of AHA Scientific Sessions in the postpandemic world, which some foresee as, potentially, an amalgam of the time-honored live format and a robust, complementary online presence.
“I can’t commit to exactly what AHA sessions will look like next November; I think that’s still being looked at,” the organization’s president-elect Donald M. Lloyd-Jones, MD, ScM, chair of the AHA Committee on Scientific Sessions Programming, told theheart.org | Medscape Cardiology.
There’s no debating that a live conference is valuable “for career networking and other opportunities, so I don’t think we can do without it. That has to be an important part of it,” he said. “When we can safely, of course.”
Still, “the virtual platform democratizes, right? I mean, it just allows greater access for a broader audience, and I think that’s important, too,” said Lloyd-Jones, MD, Northwestern University Feinberg School of Medicine, Chicago.
“I don’t think we’ll ever go completely back to it being all in-person,” he said. “I think the world has changed, and we’ll have to adapt our platforms to recognize that.”
Online, at least, meeting registrants will get a better look at Anthony Fauci, MD, than one might from the middle rows of a vast ballroom-turned-auditorium. Fauci is scheduled to speak on “Public Health and Scientific Challenges” during the Main Event Session “Latest Insights on COVID 19 and Cardiovascular Disease,” slated for the meeting’s final day.
Fauci has directed the National Institute of Allergy and Infectious Diseases (NIAID) since 1984, and has been celebrated for his leadership roles in the battles against AIDS and Ebola virus. Today, his name is close to a household word for his service as a prominent though embattled member of the White House Coronavirus Task Force.
The virtual AHA sessions will feature a core collection of LBS presentations from often high-profile clinical trials and other studies the organization deems worthy of special attention. There are nine such presentations arrayed across the meeting’s five days — from Friday, November 13 to Tuesday, November 17 — at times listed in this story and throughout the AHA Scientific Session program synched with the Central Standard Time (CST) zone of the AHA’s home office in Dallas.
Late-Breaking Science 1. Friday, November 13, 10:30 AM - 11:30 AM CST
The LBS sessions launch with the GALACTIC-HF trial, which — the world recently learned — may expand the burgeoning list of meds shown to improve clinical outcomes in chronic heart failure (HF) with reduced ejection fraction (HFrEF).
In cursory top-line results announced last month, those in the trial of more than 8000 patients who were randomly assigned to receive omecamtiv mecarbil (Amgen/Cytokinetics/Servier) showed a slight but significant benefit for the primary end point of cardiovascular (CV) death or HF events. The hazard ratio (HR), compared with standard care, was 0.92 (95% CI, 0.86 - 0.99; P = .025), noted a press release from Amgen.
Among the announcement’s few other details was a short take on safety outcomes: no difference in risk for “adverse events, including major ischemic cardiac events,” between the active and control groups. The presentation is sure to provide further insights and caveats, if any, along with other information crucial to the study’s interpretation.
Next on the schedule is the closely watched AFFIRM-AHF, billed as the first major outcomes trial of iron administration to iron-deficient patients with acute HF. It randomly assigned more than 1000 such patients to receive IV ferric carboxymaltose or a placebo. The first dose was given in-hospital and subsequent doses at home for 24 weeks or until patients were no longer iron deficient. They were followed to 1 year for the primary end point of recurrent HF hospitalizations or CV death.
The session wraps with the VITAL Rhythm trial, a substudy of the doubly randomized VITAL trial that explored the effects of vitamin D and omega-3 fatty acid supplementation on CV and cancer risk in more than 25,000 patients in the community. The substudy explored the effects of two active therapies, a preparation of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Omacor, Reliant Pharmaceuticals) or vitamin D3 supplements, on new-onset atrial fibrillation (AF) as the primary end point; it also looked at risk for sudden death.
Late-Breaking Science 2. Friday, November 13, 12:00 PM - 1:00 PM CST
Dominating the session in two presentations, the (TIPS)-3 trial explored a polypill primary-prevention strategy and daily aspirin with vitamin D supplementation in three separate placebo-controlled comparisons in more than 5700 “intermediate risk” participants 55 years and older, mostly in developing countries.
The daily polypill in this trial is a combination of hydrochlorothiazide 25 mg, atenolol 100 mg, ramipril 10 mg, and simvastatin 40 mg; aspirin was given at 75 mg daily and vitamin D at 60,000 IU monthly.
The participants are followed for a primary end point composed of major CV disease, HF, resuscitated cardiac arrest, or ischemia-driven revascularization for the polypill comparison; CV events or cancer for the aspirin comparison; and fracture risk for the vitamin D component of the trial.
In the Swedish Cardiopulmonary Bioimage Study (SCAPIS), presented third in the session, a random sample of adults from throughout Sweden, projected at about 30,000, underwent a 2-day evaluation for metabolic risk factors plus ultrasound and coronary and lung CT scans. The group has been followed for risks for myocardial infarction (MI), sudden death, and other cardiac diseases; and chronic obstructive pulmonary disease (COPD) and other lung disorders.
Late-Breaking Science 3. Saturday, November 14, 12:00 PM - 1:00 PM CST
The field may learn more mechanistically about MI associated with nonobstructed coronary arteries (MINOCA) than ever before from the Heart Attack Research Program-Imaging Study (HARP). The observational study is enrolling a projected 450 patients with suspected MI and ischemic symptoms who were referred for cardiac catheterization.
Their evaluation includes coronary optical coherence tomographic (OCT) scanning and cardiac magnetic resonance (CMR) imaging for evidence of coronary plaque disruption as the primary end point. The patients are to be followed for 10 years for a composite of death, unstable angina, stroke, recurrent MI, diagnostic or interventional catheterization, and cardiac hospitalization.
The major direct oral anticoagulant (DOAC) comparisons with warfarin in atrial fibrillation (AF) didn’t include many patients with prosthetic valve implants. In contrast, the RIVER trial enrolled 1005 adults with either persistent or paroxysmal AF and bioprosthetic mitral valves and assigned them to rivaroxaban 20 mg or the vitamin K antagonist.
The presentation will include the noninferiority primary outcome of major clinical events, which is stroke, transient ischemic attack (TIA), major bleeding, death from any cause, valve thrombosis, other systemic embolism, or HF hospitalization over 12 months.
This session also includes ALPHEUS, a trial pitting ticagrelor (Brilinta/Brilique, AstraZeneca) against mainstay clopidogrel in a setting that is mostly uncharted for such comparisons, elective percutaneous coronary intervention (PCI).
About 1900 patients with stable coronary disease were randomly assigned to a month of treatment with either agent on top of continuous aspirin. The primary end point is PCI-related MI or myocardial injury within 48 hours of the procedure.
Late-Breaking Science 4. Sunday, November 15, 9:00 AM - 10:00 AM CST
The Self-Assessment Method for Statin Side-effects Or Nocebo (SAMSON) trial may be one of the AHA 2020 frontrunners for early buzz and anticipation. So it’s with some irony that it’s also among the smallest of the LBS studies, at 60 patients, which was nonetheless considered sufficient due to its unusual design.
SAMSON is the latest and perhaps most rigorous attempt to clarify whether symptoms, especially muscle pain or discomfort, attributed to statins by many patients are pharmacologic in origin or, rather, a nocebo effect from negative expectations about statin side effects.
The study patients, all of whom had previously halted statins because of side effects, were assigned to follow three separate regimens, each for month, in a randomized order; they did that four times, for a total of 12 months. The regimens consisted of atorvastatin 20 mg daily, a placebo, or neither.
Patients kept daily logs of any perceived side effects. Parity between side effects experienced on the statin and the placebo would point to a nocebo effect, whereas a significant excess on atorvastatin would suggest they are direct drug effects.
The session also features two randomized trials each on a unique omega-3 fatty acid preparation for either secondary prevention or high-risk primary prevention, in both cases compared with a corn-oil placebo.
The Omega-3 Fatty Acids in Elderly Patients with Myocardial Infarction (OMEMI) trial randomly assigned more than 1000 elderly post-MI patients to take Pikasol (Orkla Care) at 1.8 g EPA and DHA per day or the placebo. It looked for all-cause mortality, nonfatal MI, stroke, revascularization, or hospitalization for new or worsened HF over 24 months.
The STRENGTH trial, with a planned enrollment of about 13,000 high-vascular-risk patients, looked primarily at the effect of daily treatment with Epanova (AstraZeneca), which also contains DHA and EPA, on the composite of CV death, nonfatal MI or stroke, coronary revascularization, and hospitalization for unstable angina. The trial was halted early for low likelihood of benefit, AstraZeneca announced in January of this year.
Late-Breaking Science 5. Sunday, November 15, 7:15 PM - 8:30 PM CST
Slated for the session is the primary analysis of the PIONEER 3 trial, conducted in the United States, Europe, and Japan. It compared the BuMA Supreme biodegradable drug-coated stent (SinoMed) with the durable Xience (Abbott Vascular) and Promus (Boston Scientific) drug-eluting stents. The trial followed more than 1600 patients treated for chronic stable angina or acute coronary syndrome (ACS) for the 1-year composite of cardiac death, target-vessel-related MI, and clinically driven target-lesion revascularization.
Late-Breaking Science 6. Monday, November 16, 9:00 AM - 10:00 AM CST
The EARLY-AF trial enrolled 303 patients with symptomatic paroxysmal or persistent AF suitable for catheter ablation, assigning them to pulmonary vein isolation (PVI) by cryoablation using the Arctic Front (Medtronic) system or antiarrhythmic drug therapy for rhythm control. The primary end point is time to recurrence of AF, atrial flutter, or atrial tachycardia, whether symptomatic or asymptomatic, as determined by implantable loop recorder. Patients will also be followed for symptoms and arrhythmia burden.
Also in the session, the SEARCH-AF study randomized almost 400 patients undergoing cardiac surgery who were engaged subacutely with one of two commercial portable cardiac rhythm monitoring devices (CardioSTAT, Icentia; or SEEQ, Medtronic) or, alternatively, to receive usual postoperative care
The patients, considered to be at high risk for stroke with no history of AF, were followed for the primary end point of cumulative burden of AF or atrial flutter exceeding 6 minutes or documentation of either arrhythmia by 12-lead ECG within 30 days.
Two other studies in the session look at different approaches to AF screening, one using a handheld ECG monitor in the primary care setting and the other wearable monitors in the form of a patch or wristband. The VITAL-AF presentation is titled “Screening for Atrial Fibrillation in Older Adults at Primary Care Visits Using Single Lead Electrocardiograms.” The other presentation, on the study mSToPS, is called “Three-Year Clinical Outcomes in a Nationwide, Randomized, Pragmatic Clinical Trial of Atrial Fibrillation Screening — Mhealth Screening to Prevent Strokes.”
Late-Breaking Science 7. Monday, November 16, 7:00 PM - 8:30 PM CST
In the randomized FIDELIO-DKD trial with more than 5700 patients with type 2 diabetes and associated kidney disease, those assigned to the novel mineralocorticoid receptor antagonist (MRA) finerenone (Bayer) showed an 18% drop in risk for adverse renal events, including death from renal causes (P = .001), over a median of 2.6 years. That primary outcome was previously presented in detail at a nephrology meeting and published in the New England Journal of Medicine in October.
Patients on the MRA showed a similar reduction in a composite CV-event end point, it was also reported at that time. A follow-up presentation at the AHA sessions promises to dive deeper into the trial’s CV outcomes.
In the RAPID-CTCA study, slated next for the session, 1749 patients with suspected or confirmed intermediate-risk ACS were randomly assigned to undergo computed tomographic coronary angiography (CTCA) for guiding treatment decisions or a standard-of-care strategy. It followed patients for the primary end point of death or nonfatal MI over 1 year.
Rilonacept (Arcalyst, Kiniksa/Regeneron) is an interleukin-1α and -1β inhibitor used in several autoinflammatory diseases that went unsuccessfully before regulators for the treatment of gout. The RHAPSODY trial has now explored its use against recurrent pericarditis in a randomized trial that entered 86 patients 12 years and older who had previously experienced at least three episodes.

Proinflammatory dietary pattern linked to higher CV risk
Dietary patterns with higher inflammatory potential were significantly associated with a higher incidence of cardiovascular disease (CVD) and stroke in a new pooled analysis of three prospective cohort studies.
The analysis included 210,145 U.S. women and men followed for up to 32 years in the Nurses’ Health Studies I and II and the Health Professionals Follow-up Study.
After adjustment for use of anti-inflammatory medications and CVD risk factors, those whose dietary pattern ranked in the highest quintile of inflammatory potential had a 38% higher risk of CVD (hazard ratio comparing highest with lowest quintiles, 1.38), a 46% higher risk of coronary heart disease (HR, 1.46), and a 28% higher risk of stroke (HR, 1.28) (all P for trend < .001).
Jun Li, MD, PhD, and colleagues at Harvard School of Public Health and Harvard Medical School, Boston, published the findings of their study in the Nov. 10 issue of the Journal of the American College of Cardiology.
The inflammatory potential of a diet was assessed using a food-based, dietary index called the “empirical dietary inflammatory pattern” or EDIP.
In an interview, Dr. Li explained that the EDIP was developed 4 years ago by many of the same authors involved with this study, including nutrition heavyweights Walter C. Willett, MD, DrPH, and Frank B. Hu, MD, PhD, both from Harvard.
“We summarized all the foods people eat into 39 defined food groups and did a reduced-rank regression analysis that looked at these 39 food groups and three inflammatory markers – interleukin-6, C-reactive protein, and tumor necrosis factor–alpha receptor 2. We found 18 food groups that are most predictive of these biomarkers, and the EDIP was calculated as the weighted sum of these 18 food groups.”
Individuals who had higher intakes of green-leafy vegetables (kale, spinach, arugula), dark-yellow vegetables (pumpkin, yellow peppers, carrots), whole grains, fruits, tea, coffee and wine had lower long-term CVD risk than those with higher intakes of red meat, processed meat, organ meat, refined carbohydrates, and sweetened beverages.
The associations were consistent across cohorts and between sexes and remained significant in multiple sensitivity analysis that adjusted for alcohol consumption, smoking pack-years, use of lipid-lowering and antihypertensive medications, sodium intake, and blood pressure.
In a secondary analysis, diets with higher inflammatory potential were also associated with significantly higher biomarker levels indicative of more systemic, vascular, and metabolic inflammation, as well as less favorable lipid profiles.
“We wanted to be able to provide guidance on dietary patterns and food combinations,” said Dr. Li. “If you tell people to eat more polyunsaturated fats instead of saturated fat or trans fat, most people don’t know what foods are higher and lower in those nutrients. Also, many foods have different nutrients – some of which are good and some of which are bad – so we wanted to help people find the foods with the higher proportion of healthy nutrients rather than point out specific nutrients to avoid.”
Researchers used prospectively gathered data from the Nurses’ Health Studies I and II starting from 1984 and from the Health Professionals Follow-up Study. After excluding participants with missing diet information or previously diagnosed heart disease, stroke or cancer, over 210,000 participants were included in the analysis. Participants completed a survey every 4 years to ascertain dietary intake.
Prevention, not treatment
In an editorial comment, Ramon Estruch, MD, PhD, from the Hospital Clinic in Barcelona, and colleagues suggested that it might be time for better dietary guidelines.
“A better knowledge of health protection provided by different foods and dietary patterns, mainly their anti-inflammatory properties, should provide the basis for designing even healthier dietary patterns to protect against heart disease,” the editorialists wrote.
They added extra-virgin olive oil, fatty fish, and tomatoes to the list of foods with “established anti-inflammatory activity.”
In a comment, Dr. Estruch said the findings of this new study are confirmatory of the PREDIMED trial, which showed a reduction in risk of major CV events in individuals at high cardiovascular risk assigned to an anti-inflammatory Mediterranean diet pattern supplemented with extra-virgin olive oil or nuts as compared with those assigned to a reduced-fat diet.
“The study of Jun Li et al. confirms that an anti-inflammatory diet is useful to prevent cardiovascular events and, more important, that healthy dietary patterns may be even healthier if subjects increase consumption of foods with the highest anti-inflammatory potential,” he said, adding that “mechanistic explanations add plausibility to the results of observational studies.”
Dr. Estruch was the principal investigator of PREDIMED. This trial was originally published in 2013 and then retracted and republished in 2018, with some required corrections, but the results had not materially changed.
Dr. Li is supported by grants from the National Institute of Diabetes and Digestive and Kidney Diseases and Boston Nutrition Obesity Research Center. Dr. Estruch disclosed no financial relationships relevant to the contents of this article.

Also, many foods have different nutrients – some of which are good and some of which are bad – so we wanted to help people find the foods with the higher proportion of healthy nutrients rather than point out specific nutrients to avoid.”
Researchers used prospectively gathered data from the Nurses’ Health Studies I and II starting from 1984 and from the Health Professionals Follow-up Study. After excluding participants with missing diet information or previously diagnosed heart disease, stroke or cancer, over 210,000 participants were included in the analysis. Participants completed a survey every 4 years to ascertain dietary intake.
Prevention, not treatment
In an editorial comment, Ramon Estruch, MD, PhD, from the Hospital Clinic in Barcelona, and colleagues suggested that it might be time for better dietary guidelines.
“A better knowledge of health protection provided by different foods and dietary patterns, mainly their anti-inflammatory properties, should provide the basis for designing even healthier dietary patterns to protect against heart disease,” the editorialists wrote.
They added extra-virgin olive oil, fatty fish, and tomatoes to the list of foods with “established anti-inflammatory activity.”
In a comment, Dr. Estruch said the findings of this new study are confirmatory of the PREDIMED trial, which showed a reduction in risk of major CV events in individuals at high cardiovascular risk assigned to an anti-inflammatory Mediterranean diet pattern supplemented with extra-virgin olive oil or nuts as compared with those assigned to a reduced-fat diet.
“The study of Jun Li et al. confirms that an anti-inflammatory diet is useful to prevent cardiovascular events and, more important, that healthy dietary patterns may be even healthier if subjects increase consumption of foods with the highest anti-inflammatory potential,” he said, adding that “mechanistic explanations add plausibility to the results of observational studies.”
Dr. Estruch was the principal investigator of PREDIMED. This trial was originally published in 2013 and then retracted and republished in 2018, with some required corrections, but the results had not materially changed.

Dietary patterns with higher inflammatory potential were significantly associated with a higher incidence of cardiovascular disease (CVD) and stroke in a new pooled analysis of three prospective cohort studies.
The analysis included 210,145 U.S. women and men followed for up to 32 years in the Nurses’ Health Studies I and II and the Health Professionals Follow-up Study.
After adjustment for use of anti-inflammatory medications and CVD risk factors, those whose dietary pattern ranked in the highest quintile of inflammatory potential had a 38% higher risk of CVD (hazard ratio comparing highest with lowest quintiles, 1.38), a 46% higher risk of coronary heart disease (HR, 1.46), and a 28% higher risk of stroke (HR, 1.28) (all P for trend < .001).
Jun Li, MD, PhD, and colleagues at Harvard School of Public Health and Harvard Medical School, Boston, published the findings of their study in the Nov. 10 issue of the Journal of the American College of Cardiology.
The inflammatory potential of a diet was assessed using a food-based, dietary index called the “empirical dietary inflammatory pattern” or EDIP.
In an interview, Dr. Li explained that the EDIP was developed 4 years ago by many of the same authors involved with this study, including nutrition heavyweights Walter C. Willett, MD, DrPH, and Frank B. Hu, MD, PhD, both from Harvard.
“We summarized all the foods people eat into 39 defined food groups and did a reduced-rank regression analysis that looked at these 39 food groups and three inflammatory markers – interleukin-6, C-reactive protein, and tumor necrosis factor–alpha receptor 2. We found 18 food groups that are most predictive of these biomarkers, and the EDIP was calculated as the weighted sum of these 18 food groups.”
Individuals who had higher intakes of green-leafy vegetables (kale, spinach, arugula), dark-yellow vegetables (pumpkin, yellow peppers, carrots), whole grains, fruits, tea, coffee and wine had lower long-term CVD risk than those with higher intakes of red meat, processed meat, organ meat, refined carbohydrates, and sweetened beverages.
The associations were consistent across cohorts and between sexes and remained significant in multiple sensitivity analysis that adjusted for alcohol consumption, smoking pack-years, use of lipid-lowering and antihypertensive medications, sodium intake, and blood pressure.
In a secondary analysis, diets with higher inflammatory potential were also associated with significantly higher biomarker levels indicative of more systemic, vascular, and metabolic inflammation, as well as less favorable lipid profiles.
“We wanted to be able to provide guidance on dietary patterns and food combinations,” said Dr. Li. “If you tell people to eat more polyunsaturated fats instead of saturated fat or trans fat, most people don’t know what foods are higher and lower in those nutrients.

PCI success vs. meds only in diabetes may depend on LDL-C control
In order for percutaneous coronary intervention (PCI) to shine, compared with meds alone in patients with type-2 diabetes and stable coronary disease (CAD), it needs help from aggressive control of LDL cholesterol (LDL-C) levels, suggests a patient-level meta-analysis of three major randomized trials.
Performing PCI in such patients with diabetes conferred further benefit over optimal medical therapy (OMT) for major adverse cardiac or cerebrovascular events (MACCE) only among those whose LDL-C levels had been pushed below the guidelines-specified threshold of 70 mg/dL within 1 year.
At that level of LDL-C control, PCI, compared with the meds-alone strategy, was followed by a nearly 40% drop in 4-year risk for the composite endpoint, which consisted of death from any cause or nonfatal myocardial infarction (MI) or stroke.
Also for patients reaching a 1-year LDL-C of <70 mg/dL, the risk of MACCE was similar for those who had been assigned to coronary bypass surgery (CABG), compared with PCI. But that risk was significantly lower for the CABG group among those reaching LDL-C levels above that threshold.
“The strategy of revascularization with the LDL lowering, that’s the combination that seems to be a winner” in such patients with diabetes and stable CAD, lead author Michael E. Farkouh, MD, MSc, said in an interview.
If their LDL-C “stays above 70 mg/dL, they don’t really enjoy any benefit of PCI. It’s a message to our interventional community to really drive that LDL down,” said Dr. Farkouh, of the University of Toronto. “Not only with statins, but perhaps with PCSK9 inhibitors, ezetimibe, and other therapies to lower that LDL-C.”
The analysis, published Nov. 2 in the Journal of the American College of Cardiology, pooled more than 4,000 patients with diabetes and stable CAD randomized in the BARI 2D, FREEDOM, and COURAGE trials.
The new study adds a twist to an ongoing theme throughout some meta-analyses and clinical trials like ISCHEMIA since the results of COURAGE were unveiled 13 years ago. The latter trial famously saw no significant difference in death, MI, or stroke in patients with stable CAD assigned to OMT with or without PCI. That set off years of controversy about the relative merits of the revascularization and meds-only strategies in stable CAD that persists today.
But, Dr. Farkouh proposed, whether PCI improves clinical outcomes, compared with meds alone, at least in patients with diabetes, may be tied to the success of LDL-C-lowering therapies in reaching that goal, which in the current study was below 70 mg/dL.
“In this analysis of pooled data from the three major trials, we demonstrate that attaining that level of LDL-C at 1 year portends a better outcome for PCI” in patients with diabetes and stable CAD, he said.
The findings “probably need to be studied further, but it is compelling to think that if we can drive the LDL-C down by one year after the procedure, we have better outcomes with PCI,” compared with a meds-only strategy in patients with diabetes and stable CAD. “That really vindicates a lot of those who believe in PCI,” Dr. Farkouh said.
“What’s surprising to me is, if the patient has an LDL less than 70, why is it that there is a benefit of PCI, compared to medical therapy alone? Because they’re already so aggressively managed, you would think there shouldn’t be a benefit,” Sripal Bangalore, MD, MHA, New York University, said in an interview. “For me, that part is difficult to understand.”
The finding somewhat contradicts the results of ISCHEMIA, in which OMT – including LDL-C-lowering therapy – was considered more aggressive than usually managed in practice, Bangalore said. Yet the trial saw no outcomes difference between PCI and the more conservative approach, leading some to speculate that PCI may be a better choice when, for whatever reason, medical therapy isn’t optimal.
The observed superiority of PCI over meds-only at the lowest LDL-C levels is, according to Dr. Banagalore, “more likely because of residual confounding, given the fact that they’re combining three different trials, which are aimed to address different sets of questions.” He was an investigator with the FREEDOM and ISCHEMIA trials but isn’t associated with the current report.
The main message from this observational analysis is that “of course, we want to get the LDL as low as possible in these patients with demonstrated cardiovascular disease and diabetes,” Donald M. Lloyd-Jones, MD, ScM, Northwestern University, Chicago, said in an interview. “Every one of these patients should be shooting for as low an LDL as possible.”
Regardless of revascularization strategy, he said, “we have to get people on a high-intensity statin, or at least their maximally targeted dose, and have a careful and thoughtful conversation about whether they need additional lowering with, perhaps, ezetimibe, if they’re not below the thresholds we’d like to see them at, in this case, 70 mg/dL.”
Still, the current findings that the relative effects of PCI and CABG in these patients may vary by degree of LDL-C reduction “are interesting, but would have to be tested a little bit more directly,” said Dr. Lloyd-Jones, who is not affiliated with the analysis.
An accompanying editorial, which also acknowledges the study’s limitations, says its results “are relevant for clinical practice and may pave the way toward the generation of novel personalized medicine models that can optimize care of patients with type-2 diabetes.”
They “support the concept of an individualized treatment strategy that accounts for a patient’s LDL-C level to estimate clinical outcomes and expected treatment effects after therapeutic interventions,” say the authors, led by Eliano P. Navarese, MD, PhD, Nicolaus Copernicus University, Bydgoszcz, Poland.
“For daily practice, these results also underscore the importance of follow-up LDL-C measurements, both as a risk stratifier and as an indicator for therapy adjustments,” they write, noting that “current guidelines provide no formal recommendation on when to check LDL-C after PCI.”
The meta-analysis followed a total of 4050 patients with diabetes and stable CAD from the three randomized trials, those with evaluable baseline and follow-up LDL-C measurements, for a median of 4 years after the 1-year LDL-C assessment. At that time, at least 90% of patients in each of the trials had statin prescriptions, the group reported.
At one year, 34.5% of the total cohort had an LDL-C <70 mg/dL; their mean was 55.8 mg/dL.
And 42.2% had an LDL-C from 70 mg/dL to <100 mg/dL; their mean was 83.4 mg/dL. Compared with patients with an LDL-C <70 mg/dL, their adjusted hazard ratio for the composite endpoint was not elevated at 1.07 (95% CI, 0.86-1.32, P = .54).
Finally, 23.2% had an LDL-C ≥100 mg/dL; the mean was 123.0 mg/dL. Compared with the group with the lowest 1-year LDL-C, their adjusted HR for MACCE was increased at 1.46 (95% CI, 1.15 - 1.85, P = .002).
That HR among the 42.3% of patients in the PCI cohort, compared with the 33.3% assigned to meds only, climbed significantly only among those in the lowest 1-year LDL-C stratum: HR, 0.61 (95% CI, 0.40-0.91, P = .016). Corresponding HRs in the mid-range and highest 1-year LDL strata were close to unity and nonsignificant at P = .71 and P = .98, respectively.
On the other hand, the 24.4% of patients assigned to CABG showed better MACCE outcomes than those in the meds-only group across all three 1-year LDL-C strata.
The risk of MACCE wasn’t significantly altered by CABG, compared with PCI among patients achieving a 1-year LDL-C less than 70 mg/dL. However, it fell by about one-half for CABG vs. PCI in both the mid-range and highest 1-year LDL-C strata, P = .003 and P = .022, respectively.
Dr. Bangalore said he’s entirely behind the results of the study’s comparison of PCI and CABG. “It’s exactly the hypothesis that I’ve been putting forward, that if you want to achieve results as good as CABG, do PCI with aggressive medical therapy.” That means second-generation drug-eluting stents for the target lesions, “and aggressive medical therapy to address all of the nontarget lesions, specifically in diabetics.”
It’s possible, Dr. Lloyd-Jones said, that there is “no longer a dichotomy between revascularization strategies,” with respect to clinical outcomes, in such patients who maintain an LDL less than 70 mg/dL, as the study suggests.
“But I wonder, if it had continued for another 4 years of follow-up, whether we would see the CABG patients start to have more events,” such that the CABG advantage goes away at higher LDL-C levels, he proposed.
Or, Dr. Lloyd-Jones speculated, if all patients had achieved LDL-C below 70 mg/dL, “would there be such a difference between the PCI and CABG groups? My bet would be that it would be small or abolished.”

On the other hand, the 24.4% of patients assigned to CABG showed better MACCE outcomes than those in the meds-only group across all three 1-year LDL-C strata.
The risk of MACCE wasn’t significantly altered by CABG, compared with PCI among patients achieving a 1-year LDL-C less than 70 mg/dL. However, it fell by about one-half for CABG vs. PCI in both the mid-range and highest 1-year LDL-C strata, P = .003 and P = .022, respectively.
Dr. Bangalore said he’s entirely behind the results of the study’s comparison of PCI and CABG. “It’s exactly the hypothesis that I’ve been putting forward, that if you want to achieve results as good as CABG, do PCI with aggressive medical therapy.” That means second-generation drug-eluting stents for the target lesions, “and aggressive medical therapy to address all of the nontarget lesions, specifically in diabetics.”
It’s possible, Dr. Lloyd-Jones said, that there is “no longer a dichotomy between revascularization strategies,” with respect to clinical outcomes, in such patients who maintain an LDL less than 70 mg/dL, as the study suggests.
“But I wonder, if it had continued for another 4 years of follow-up, whether we would see the CABG patients start to have more events,” such that the CABG advantage goes away at higher LDL-C levels, he proposed.
Or, Dr. Lloyd-Jones speculated, if all patients had achieved LDL-C below 70 mg/dL, “would there be such a difference between the PCI and CABG groups? My bet would be that it would be small or abolished.”

Lupus-specific predictors for CVD described in Black patients
Black patients with systemic lupus erythematosus (SLE) are known to have significantly elevated risk for stroke and ischemic heart disease (IHD), compared with non-Black patients with SLE.
Now a team of investigators has identified SLE-specific predictors for major cardiovascular complications in Black patients, pointing to potential prevention strategies in this high-risk population.
Among Black patients in a study of 336 patients with incident SLE, discoid rash at the time of SLE diagnosis predicted a fivefold higher risk for stroke, and renal disorder at the time of diagnosis was associated with a twofold higher risk, compared with non-Black patients, but neither of these symptoms predicted elevated risk of IHD.
In contrast, neurologic disorders, including prior psychosis or seizure, were associated with a fourfold higher risk for IHD, and immunologic disorders including anti-DNA, anti-Smith, or antiphospholipid antibodies were associated with a nearly fivefold greater risk for IHD in Black patients, but neither of these comorbidities predicted strokes, reported Shivani Garg, MD, assistant professor of medicine at the University of Wisconsin in Madison.
“Our study was one of the first to highlight racial disparities in CVD subtypes, with a threefold higher stroke risk and 24-fold higher ischemic heart disease risk in Black patients with lupus. Compared to previous studies in Black populations, our study highlights different peak timing of early stroke and ischemic heart disease in our cohort,“ she said at a plenary session during the virtual annual meeting of the American College of Rheumatology.
The study is one of the first to identify specific and unique SLE disease-related predictors of stroke and ischemic heart disease, she said.
Georgia Lupus Registry data
Dr. Garg and colleagues at the University of Wisconsin and Emory University in Atlanta drew on data from the Georgia Lupus Registry, a population-based registry of SLE patients from the Atlanta area. They identified patients diagnosed from 2002 through 2004 who had four or more ACR criteria for SLE, or three or more criteria plus a final diagnosis of SLE made by their board-certified rheumatologists.
The patients were matched to the Georgia Hospital Discharge Database and National Death Index from 2000 through 2013, with stroke- and IHD-related hospitalizations and deaths classified by the first three admission codes or cause-of-death codes.
Patients with transient ischemic attacks were included in the stroke category, and those with myocardial infarction and angina were included in the IHD category.
They identified 336 patients, 87% of whom were female, and 75% of whom were Black. The mean age at SLE diagnosis was 40 years. Among this cohort, there were 38 stroke-related events or deaths and 25 IHD-related events or deaths recorded from the period 2 years before through 14 years after an SLE diagnosis.
Early stroke, late IHD
The investigators first looked at the timing of stroke vs. IHD and found that a disproportionately high percentage of stroke events occurred in the second year after SLE diagnosis, whereas the peak of IHD-related events occurred in the 14th year after diagnosis.
They then performed a race-stratified Cox proportional hazard analysis, and found a threefold higher risk for stroke in Black patients versus non-Black patients (P = .007) and a 24-fold higher risk for IHD (P < .0001).
In multivariate analysis, significant predictors of stroke were Black race with a hazard ratio (HR) of 3.4 (P = .028), discoid rash (HR, 4.6; P = .0028), and renal disorder (HR, 2.4; P = .04). However, stroke was not predicted by age, sex, immunologic disorder, serositis, hematologic disorder, or ACR criteria total greater than four.
Significant predictors of IHD included age 65 and older (HR, 61; P = .0007), Black race (HR, 24; P = .004), neurologic disorder (HR, 4.0; P = .018), and immunologic disorder (HR, 4.7; P = .02). But IHD could not be predicted by oral ulcers, discoid rash, or ACR criteria more than four.
“In future studies, we will examine mechanisms that drive the different timing and predictors of CVD subtypes and disparities. We will also examine the impact of timely prevention in high-risk SLE subsets,” Dr. Garg said.
Managing CVD risk
Angus Worthing, MD, from Arthritis & Rheumatism Associates in Chevy Chase, Md., and Washington, D.C., who moderated a press briefing where Dr. Garg discussed her data, routinely treats patients of different racial backgrounds with lupus. When asked how he manages patients with SLE and suspected cardiovascular complications, Dr. Worthing said, “I tend to, in my practice – and these kinds of studies may change what I do – watch for symptoms that might reflect coronary artery disease or cerebrovascular disease, potentially looking at the smaller arteries in the hands and feet as clues, and I will refer promptly to a vascular surgery expert or cardiologist for screening,” he said.
Dr. Garg added that in her practice, she and colleagues treat high-risk subsets of patients, such as those with lupus nephritis or multiple comorbidities, with aggressive blood pressure control and monitoring, as well as smoking cessation recommendations and lipid monitoring. They also try to limit or, if possible, decrease steroid doses to reduce risk for cardiovascular side effects.
Support for the study came in part from the U.S. Centers for Disease Control and Prevention. Dr. Garg and Dr. Worthing reported having no relevant disclosures.

FROM ACR 2020
Is the tide turning on the ‘grubby’ affair of EXCEL and the European guidelines?
“I disapprove of what you say, but I will defend to the death your right to say it.” The choice of the secretary general of the European Association for Cardio-Thoracic Surgery to open with this quote was the first hint that the next presentation at the 2019 annual meeting would be anything but dull. The session chair followed with a reminder to keep the discussion polite and civil.
Presenter David Taggart, MD, PhD, did not disappoint. The professor of cardiovascular surgery at the University of Oxford (England) began with the announcement that he had withdrawn his name from a recent paper in the New England Journal of Medicine. He then proceeded to accuse his coinvestigators of misrepresenting the findings of a major clinical trial.
Dr. Taggart was chair of the surgical committee for the Abbott-sponsored EXCEL trial, which compared two procedures for patients who had blockages in their left main coronary artery: percutaneous coronary intervention (PCI) using coronary stents, and coronary artery bypass graft surgery (CABG). The investigators designed the trial to compare outcomes for the two treatments using a composite endpoint of death, stroke, and MI. The 3-year follow-up data had been published in NEJM without controversy – or, at least, without public controversy.
But when it came time to publish the 5-year follow-up, there was a significantly higher rate of death in the stent group, and both Dr. Taggart and the journal editors were concerned that this finding was being downplayed in the manuscript.
In their comments to the authors, the journal editors had recommended including the mortality difference (unless clearly trivial) ‘”in the concluding statement in the final paragraph.” Yet, the concluding statement of the published paper read that there “was no significant difference between PCI and CABG.”
In Dr. Taggart’s view, that claim was dangerous for patients, and so he was left with no choice but to remove himself as an author, a first for the academic with over 300 scientific papers to his name.
Earlier publications from the EXCEL trial had influenced European treatment guidelines. But subsequent allegations of misconduct and hidden data spurred the EACTS to repudiate those guidelines out of concern “that some results in the EXCEL trial appear to have been concealed and that some patients may therefore have received the wrong clinical advice.”
The controversy pitted cardiothoracic surgeons against interventional cardiologists, who were seen as increasingly encroaching on the surgeons’ turf. Dr. Taggart was a long-time critic of the subspecialty.
Surgeons demanded an independent analysis of the EXCEL trial data – a demand that the investigators have yet to satisfy. Dr. Taggart was the first to speak publicly, but others had major reservations about the trial reporting and conduct years earlier.
Mortality data held back
One such person was Lars Wallentin, MD, a professor of cardiology at Uppsala (Sweden) University Hospital, who chaired the independent committee that monitored the safety and scientific validity of the EXCEL trial.
The committee, known as the data and safety monitoring board (DSMB), received a report on March 23, 2016, that showed that increasingly more patients who had received stents were dying, compared with the group of patients that had undergone CABG. A graph of the survival curves showed the gap between the two groups widening after 3 years (Figure 1).
By September of that year, Dr. Wallentin and other members of the DSMB were anxious to share the concerning mortality difference with the broader medical community.
They were aware that EACTS and the European Society of Cardiology had started the process of updating their guidelines on myocardial revascularization, and were keen for the guideline writing committee to see all of the data.
Meanwhile, the trial investigators, led by principal investigator Gregg Stone, MD, then at New York–Presbyterian Hospital and Columbia University Medical Center, were preparing to publish a report of the 3-year outcomes. Recruitment for EXCEL started in September 2010, so at the time of the 3-year analysis in 2016, some patients had been followed up for over 5 years. But the data, published in NEJM in October 2016, were capped at 3 years (Figure 2). It didn’t show the widening gap in late mortality that Dr. Wallentin and the rest of the DSMB had seen.
When asked about this, the investigators said they were transparent about their plans to cap the data at 3 years in an amendment to the study protocol. Stone’s coprincipal investigators were interventional cardiologist Patrick Serruys, MD, then of Imperial College London; and two surgeons: Joseph Sabik, MD, then of the Cleveland Clinic Foundation, and A. Pieter Kappetein, MD, PhD, then at Erasmus Medical Center, Rotterdam. The four principal investigators all declared financial payments from stent manufacturers either to themselves or their institutions.
Study sponsor Abbott has distanced itself from the decisions made and has referred all questions about the trial to the EXCEL investigators. Charles Simonton, chief medical officer at Abbott (now at Abiomed) was a coauthor on both the 3- and 5-year papers. Dr. Wallentin believes that the sponsor must have been aware of the DSMB’s concerns.
Continuing DSMB concerns
A year later, the DSMB was still troubled. Dr. Wallentin emailed Dr. Stone in September 2017 asking for an updated analysis of the mortality data without any capping in time.
Dr. Wallentin added that he didn’t think that unblinding the mortality results would be an issue at that stage because these were late deaths in a trial where the interventions were long completed. But, he warned, “it might be very concerning if, in the future, suspicions were raised that already available information on mortality was withheld from the cardiology and thoracic surgery community.”
The investigators took a month to respond. They declined the request, saying that the trial was not statistically powered to measure mortality. In his email to Dr. Wallentin, Dr. Stone stressed that they were committed to complete disclosure of all of the EXCEL data and that the responsible time point to unblind was after 4 years. His coprincipal investigators (Dr. Serruys, Dr. Sabik, and Dr. Kappetein) as well as EXCEL statistical committee chair Stuart Pocock, PhD, and Mr. Simonton were all copied on the email.
Dr. Wallentin deferred to the principal investigators’ arguments.
Missing MI data
Death was not the only outcome of the EXCEL trial to draw scrutiny.
The EXCEL investigators used a unique definition of MI that was almost exclusively based on a rise in the cardiac biomarker CK-MB. This protocol definition of MI was later adapted into the Society for Cardiovascular Angiography and Interventions definition in a paper coauthored by Dr. Stone. The investigators agreed to also measure MIs that met the more commonly used Third Universal Definition as a secondary endpoint. The Third Universal Definition of Myocardial Infarction uses a change in biomarkers – preferably troponin or alternatively CK-MB – coupled with other clinical signs.
It is standard practice to report secondary endpoints in any analysis of the main findings of a study. Yet, the EXCEL investigators did not report the universal definition of MI in either the 3-year or 5-year publications.
This is critical because MI according to one definition may not count according to the other, and the final tally could tip the trial results positive, negative, or neutral for coronary stents.
In Dr. Taggart’s opinion, the protocol definition puts CABG at a disadvantage because it uses the same biomarker threshold for procedural-related MI for both PCI and CABG. Because surgery involves more manipulation of the heart, cardiac enzyme levels will naturally be higher after CABG than PCI. These procedure-related enzyme elevations are not “true clinical MIs,” according to Dr. Taggart and others.
Late last year, a dataset containing the 3-year follow-up of EXCEL, including the information on the universal definition of MI, was leaked to the BBC. Working with biostatisticians, the BBC confirmed that according to this definition, there were more MIs in the stent group.
Originally, the investigators disputed the finding, calling the BBC data “imaginary.” They claimed that they were unable to calculate a rate of MI according to the universal definition because they lacked routine collection of troponins, although the universal definition also allows use of CK-MB. They have since published an analysis of 5-year MI data according to the universal definition, which showed twice the rate of MI in the PCI group.
From the leaked data, the BBC calculated the main composite endpoint of death, stroke, and MI using the universal definition of MI. Now the results swung in favor of CABG.
Impact on guidelines
None of this was known at the time the European cardiology societies convened a committee to write their new guidelines on myocardial revascularization. The writing panel disagreed about whether PCI and CABG were equivalent for patients with left main coronary artery disease (CAD).
Besides EXCEL, another study, the NOBLE trial, compared PCI and CABG in left main CAD and came to opposite conclusions – conclusions that matched the leaked data. In that trial, European investigators chose a slightly different primary endpoint: a composite of death, MI, stroke, and the need for a repeat procedure. They used the universal definition of MI exclusively, and notably, they omitted procedural MI from their clinical event count. The results, published at the same time as the EXCEL 3-year findings, suggested that CABG was better.
Given the discrepant findings of two large trials, the guideline committee considered all of the available data comparing the two methods of revascularization for left main CAD. But even then, things weren’t clear-cut. One draft meta-analysis, supported by the National Institute for Health Research, suggested that results were worse for first- and second-generation drug-eluting coronary stents – including those used in EXCEL – compared with surgery.
Another meta-analysis, later published in The Lancet, drew a different conclusion and found that PCI was just as good as surgery. The main author, Stuart Head, a cardiothoracic surgeon on the ESC/EACTS guideline committee, was a research fellow with EXCEL investigator Dr. Kappetein at Erasmus. EXCEL investigators Dr. Stone, Dr. Kappetein, and Dr. Serruys were coauthors of the Lancet meta-analysis.
There was heated discussion about the committee’s draft recommendations, which gave both CABG and PCI a Class IA recommendation in patients with left main CAD and low anatomical complexity. In October 2017, the ESC commissioned an anonymous external reviewer to weigh in. James Brophy, MD, PhD, a cardiologist and professor of medicine and epidemiology at McGill University, Montreal, confirmed that he was the reviewer after he published an updated version in June 2020.
Looking at all of the data available at the time comparing the procedures for left main CAD, Dr. Brophy’s analysis suggested a 73% chance that the excess in death, stroke, or MI represents at least two excess events per 100 patients treated with PCI rather than CABG.
Dr. Brophy thought that most patients would find these differences clinically meaningful and advised against giving both procedures the same class of recommendation. He was also concerned that many readers will skip to the summary recommendation table without reading the entire guideline document.
“I feel this is misleading in its present form,” he wrote in 2017.
Despite Dr. Brophy’s review, the guideline committee stuck with its original recommendations. The final 2018 ESC/EACTS Guidelines on myocardial revascularization gave equal weight to both CABG and PCI in patients with left main CAD and low anatomical complexity. In contrast, US guidelines do not put PCI and CABG on the same footing for any group of patients with left main CAD.
The lead author of the ESC/EACTS guidelines section on left main disease, and around a third of those on the writing task force, all declared financial payments from stent manufacturers either to themselves or their institutions. The EXCEL principal investigator, Dr. Kappetein, was secretary general of EACTS and oversaw the guidelines process for the surgical organization. He left to work for Medtronic midway through the process and was later joined there by his former research fellow, Stuart Head.
Dr. Brophy said in an interview that given the final guideline recommendations, he assumed that the committee had other reviews and went with the majority opinion.
But not everyone involved in the guidelines saw Dr. Brophy’s review. Nick Freemantle, a statistical reviewer appointed by EACTS, expected to see it but didn’t. This omission calls into question the neutrality of the whole process, in his view.
Mr. Freemantle believes that the deck was stacked so that he only saw the pieces of evidence that supported the conclusions that were already decided and that he was not shown “the bits that don’t fit that neatly.”
“And without that narrative, it all feels a bit grubby, to be honest,” he said.
Professor Barbara Casadei, ESC president, disputed this, saying that the guidelines were approved by all surgical members, including the EACTS council.
Missing from Dr. Brophy’s review were the later data from EXCEL. As he had told the DSMB in 2017, Stone presented the 4-year data from EXCEL at the TCT conference in September 2018. At this point, the analysis showed that 10.3% of people had died after PCI and 7.4% after CABG.
But this presentation was not given much prominence at the conference, which Dr. Stone organized, and occurred during a didactic session in a small room rather than on one of the main stages where the 3-year data from EXCEL were announced with much fanfare. The presentation also took place 3 weeks after the European guidelines were published.
Surgeons withdraw support
After the BBC report last year that the universal definition of MI data had been collected but not published in the 3-year follow-up manuscript, and showed more MI in the PCI group than the protocol definition, the EACTS withdrew its support for the guidelines. The ESC continued to uphold the guidelines «until there is robust scientific evidence (as opposed to allegations) indicating we should do otherwise,” said Ms. Casadei.
A spokesperson for NEJM said the journal stood by the EXCEL papers because “there is no credible harm to patients from the publication of the paper and accurate reporting of trial results.” NEJM has since conducted a review and published a series of letters in response. The letters have reinvigorated rather than appeased the dissenters, as reported by Medscape.
A number of cardiologists and researchers started a petition on change.org to revise the EACTS/ESC left main CAD guidelines, and surgical societies across the globe have written to the editor of NEJM asking him to retract or amend the EXCEL papers.
This has not happened. The journal’s editor maintains that the letters containing the analyses are “sufficient information” to allow readers and guideline authors to “evaluate the trial findings.”
Dr. Taggart was dismissive of that response. “There is still no recognition or acknowledgment that failure to publish these data in 2016 ‘misled’ the guideline writers for the ESC/EACTS guidelines, and there is still no formal correction of the 2016 and 2019 NEJM manuscripts.”
Over a year after the BBC received the leaked data, the EXCEL investigators published an analysis of the primary outcome using the universal definition of MI data in the Journal of the American College of Cardiology.
It shows 141 events in the PCI arm, compared with 102 in the CABG arm. The investigators acknowledge that the rates of procedural MI differ depending on the definition used. According to their analysis, the protocol definition was predictive of mortality after both treatments, whereas the universal definition of procedural MI was predictive of mortality only after CABG. Not everyone agrees with this interpretation, and an accompanying editorial questioned these conclusions.
For Dr. Wallentin, it’s a relief that these data are in the public domain so that their interpretation and clinical consequences can be “openly discussed.” He hoped that the whole experience will result in something constructive and useful for the future.
As for the guidelines, the tide may be turning.
In a joint statement with EACTS on Oct. 6, 2020, the ESC agreed to review its guidelines for left main disease in the light of emerging, longer-term outcome data from the trials of CABG versus PCI.
Dr. Taggart has no regrets about speaking out despite this being “an exceedingly painful and bruising experience.”

“I disapprove of what you say, but I will defend to the death your right to say it.” The choice of the secretary general of the European Association for Cardio-Thoracic Surgery to open with this quote was the first hint that the next presentation at the 2019 annual meeting would be anything but dull. The session chair followed with a reminder to keep the discussion polite and civil.
Presenter David Taggart, MD, PhD, did not disappoint. The professor of cardiovascular surgery at the University of Oxford (England) began with the announcement that he had withdrawn his name from a recent paper in the New England Journal of Medicine. He then proceeded to accuse his coinvestigators of misrepresenting the findings of a major clinical trial.
Dr. Taggart was chair of the surgical committee for the Abbott-sponsored EXCEL trial, which compared two procedures for patients who had blockages in their left main coronary artery: percutaneous coronary intervention (PCI) using coronary stents, and coronary artery bypass graft surgery (CABG). The investigators designed the trial to compare outcomes for the two treatments using a composite endpoint of death, stroke, and MI. The 3-year follow-up data had been published in NEJM without controversy – or, at least, without public controversy.
But when it came time to publish the 5-year follow-up, there was a significantly higher rate of death in the stent group, and both Dr. Taggart and the journal editors were concerned that this finding was being downplayed in the manuscript.
In their comments to the authors, the journal editors had recommended including the mortality difference (unless clearly trivial) ‘”in the concluding statement in the final paragraph.” Yet, the concluding statement of the published paper read that there “was no significant difference between PCI and CABG.”
In Dr. Taggart’s view, that claim was dangerous for patients, and so he was left with no choice but to remove himself as an author, a first for the academic with over 300 scientific papers to his name.
Earlier publications from the EXCEL trial had influenced European treatment guidelines. But subsequent allegations of misconduct and hidden data spurred the EACTS to repudiate those guidelines out of concern “that some results in the EXCEL trial appear to have been concealed and that some patients may therefore have received the wrong clinical advice.”
The controversy pitted cardiothoracic surgeons against interventional cardiologists, who were seen as increasingly encroaching on the surgeons’ turf. Dr. Taggart was a long-time critic of the subspecialty.
Surgeons demanded an independent analysis of the EXCEL trial data – a demand that the investigators have yet to satisfy. Dr. Taggart was the first to speak publicly, but others had major reservations about the trial reporting and conduct years earlier.
Mortality data held back
One such person was Lars Wallentin, MD, a professor of cardiology at Uppsala (Sweden) University Hospital, who chaired the independent committee that monitored the safety and scientific validity of the EXCEL trial.
The committee, known as the data and safety monitoring board (DSMB), received a report on March 23, 2016, that showed that increasingly more patients who had received stents were dying, compared with the group of patients that had undergone CABG. A graph of the survival curves showed the gap between the two groups widening after 3 years (Figure 1).
By September of that year, Dr. Wallentin and other members of the DSMB were anxious to share the concerning mortality difference with the broader medical community.
They were aware that EACTS and the European Society of Cardiology had started the process of updating their guidelines on myocardial revascularization, and were keen for the guideline writing committee to see all of the data.
Meanwhile, the trial investigators, led by principal investigator Gregg Stone, MD, then at New York–Presbyterian Hospital and Columbia University Medical Center, were preparing to publish a report of the 3-year outcomes. Recruitment for EXCEL started in September 2010, so at the time of the 3-year analysis in 2016, some patients had been followed up for over 5 years. But the data, published in NEJM in October 2016, were capped at 3 years (Figure 2). It didn’t show the widening gap in late mortality that Dr. Wallentin and the rest of the DSMB had seen.
When asked about this, the investigators said they were transparent about their plans to cap the data at 3 years in an amendment to the study protocol. Stone’s coprincipal investigators were interventional cardiologist Patrick Serruys, MD, then of Imperial College London; and two surgeons: Joseph Sabik, MD, then of the Cleveland Clinic Foundation, and A. Pieter Kappetein, MD, PhD, then at Erasmus Medical Center, Rotterdam. The four principal investigators all declared financial payments from stent manufacturers either to themselves or their institutions.
Study sponsor Abbott has distanced itself from the decisions made and has referred all questions about the trial to the EXCEL investigators. Charles Simonton, chief medical officer at Abbott (now at Abiomed) was a coauthor on both the 3- and 5-year papers. Dr. Wallentin believes that the sponsor must have been aware of the DSMB’s concerns.
Continuing DSMB concerns
A year later, the DSMB was still troubled. Dr. Wallentin emailed Dr. Stone in September 2017 asking for an updated analysis of the mortality data without any capping in time.
Dr. Wallentin added that he didn’t think that unblinding the mortality results would be an issue at that stage because these were late deaths in a trial where the interventions were long completed. But, he warned, “it might be very concerning if, in the future, suspicions were raised that already available information on mortality was withheld from the cardiology and thoracic surgery community.”
The investigators took a month to respond. They declined the request, saying that the trial was not statistically powered to measure mortality. In his email to Dr. Wallentin, Dr. Stone stressed that they were committed to complete disclosure of all of the EXCEL data and that the responsible time point to unblind was after 4 years. His coprincipal investigators (Dr. Serruys, Dr. Sabik, and Dr. Kappetein) as well as EXCEL statistical committee chair Stuart Pocock, PhD, and Mr. Simonton were all copied on the email.
Dr. Wallentin deferred to the principal investigators’ arguments.
Missing MI data
Death was not the only outcome of the EXCEL trial to draw scrutiny.
The EXCEL investigators used a unique definition of MI that was almost exclusively based on a rise in the cardiac biomarker CK-MB. This protocol definition of MI was later adapted into the Society for Cardiovascular Angiography and Interventions definition in a paper coauthored by Dr. Stone. The investigators agreed to also measure MIs that met the more commonly used Third Universal Definition as a secondary endpoint. The Third Universal Definition of Myocardial Infarction uses a change in biomarkers – preferably troponin or alternatively CK-MB – coupled with other clinical signs.
It is standard practice to report secondary endpoints in any analysis of the main findings of a study. Yet, the EXCEL investigators did not report the universal definition of MI in either the 3-year or 5-year publications.
This is critical because MI according to one definition may not count according to the other, and the final tally could tip the trial results positive, negative, or neutral for coronary stents.
In Dr. Taggart’s opinion, the protocol definition puts CABG at a disadvantage because it uses the same biomarker threshold for procedural-related MI for both PCI and CABG. Because surgery involves more manipulation of the heart, cardiac enzyme levels will naturally be higher after CABG than PCI. These procedure-related enzyme elevations are not “true clinical MIs,” according to Dr. Taggart and others.
Late last year, a dataset containing the 3-year follow-up of EXCEL, including the information on the universal definition of MI, was leaked to the BBC. Working with biostatisticians, the BBC confirmed that according to this definition, there were more MIs in the stent group.
Originally, the investigators disputed the finding, calling the BBC data “imaginary.” They claimed that they were unable to calculate a rate of MI according to the universal definition because they lacked routine collection of troponins, although the universal definition also allows use of CK-MB. They have since published an analysis of 5-year MI data according to the universal definition, which showed twice the rate of MI in the PCI group.
From the leaked data, the BBC calculated the main composite endpoint of death, stroke, and MI using the universal definition of MI. Now the results swung in favor of CABG.
Impact on guidelines
None of this was known at the time the European cardiology societies convened a committee to write their new guidelines on myocardial revascularization. The writing panel disagreed about whether PCI and CABG were equivalent for patients with left main coronary artery disease (CAD).
Besides EXCEL, another study, the NOBLE trial, compared PCI and CABG in left main CAD and came to opposite conclusions – conclusions that matched the leaked data. In that trial, European investigators chose a slightly different primary endpoint: a composite of death, MI, stroke, and the need for a repeat procedure. They used the universal definition of MI exclusively, and notably, they omitted procedural MI from their clinical event count. The results, published at the same time as the EXCEL 3-year findings, suggested that CABG was better.
Given the discrepant findings of two large trials, the guideline committee considered all of the available data comparing the two methods of revascularization for left main CAD. But even then, things weren’t clear-cut. One draft meta-analysis, supported by the National Institute for Health Research, suggested that results were worse for first- and second-generation drug-eluting coronary stents – including those used in EXCEL – compared with surgery.
Another meta-analysis, later published in The Lancet, drew a different conclusion and found that PCI was just as good as surgery. The main author, Stuart Head, a cardiothoracic surgeon on the ESC/EACTS guideline committee, was a research fellow with EXCEL investigator Dr. Kappetein at Erasmus. EXCEL investigators Dr. Stone, Dr. Kappetein, and Dr. Serruys were coauthors of the Lancet meta-analysis.
There was heated discussion about the committee’s draft recommendations, which gave both CABG and PCI a Class IA recommendation in patients with left main CAD and low anatomical complexity. In October 2017, the ESC commissioned an anonymous external reviewer to weigh in. James Brophy, MD, PhD, a cardiologist and professor of medicine and epidemiology at McGill University, Montreal, confirmed that he was the reviewer after he published an updated version in June 2020.
Looking at all of the data available at the time comparing the procedures for left main CAD, Dr. Brophy’s analysis suggested a 73% chance that the excess in death, stroke, or MI represents at least two excess events per 100 patients treated with PCI rather than CABG.
Dr. Brophy thought that most patients would find these differences clinically meaningful and advised against giving both procedures the same class of recommendation. He was also concerned that many readers will skip to the summary recommendation table without reading the entire guideline document.
“I feel this is misleading in its present form,” he wrote in 2017.
Despite Dr. Brophy’s review, the guideline committee stuck with its original recommendations. The final 2018 ESC/EACTS Guidelines on myocardial revascularization gave equal weight to both CABG and PCI in patients with left main CAD and low anatomical complexity. In contrast, US guidelines do not put PCI and CABG on the same footing for any group of patients with left main CAD.
The lead author of the ESC/EACTS guidelines section on left main disease, and around a third of those on the writing task force, all declared financial payments from stent manufacturers either to themselves or their institutions. The EXCEL principal investigator, Dr. Kappetein, was secretary general of EACTS and oversaw the guidelines process for the surgical organization. He left to work for Medtronic midway through the process and was later joined there by his former research fellow, Stuart Head.
Dr. Brophy said in an interview that given the final guideline recommendations, he assumed that the committee had other reviews and went with the majority opinion.
But not everyone involved in the guidelines saw Dr. Brophy’s review. Nick Freemantle, a statistical reviewer appointed by EACTS, expected to see it but didn’t. This omission calls into question the neutrality of the whole process, in his view.
Mr. Freemantle believes that the deck was stacked so that he only saw the pieces of evidence that supported the conclusions that were already decided and that he was not shown “the bits that don’t fit that neatly.”
“And without that narrative, it all feels a bit grubby, to be honest,” he said.
Professor Barbara Casadei, ESC president, disputed this, saying that the guidelines were approved by all surgical members, including the EACTS council.
Missing from Dr. Brophy’s review were the later data from EXCEL. As he had told the DSMB in 2017, Stone presented the 4-year data from EXCEL at the TCT conference in September 2018. At this point, the analysis showed that 10.3% of people had died after PCI and 7.4% after CABG.
But this presentation was not given much prominence at the conference, which Dr. Stone organized, and occurred during a didactic session in a small room rather than on one of the main stages where the 3-year data from EXCEL were announced with much fanfare. The presentation also took place 3 weeks after the European guidelines were published.
Surgeons withdraw support
After the BBC report last year that the universal definition of MI data had been collected but not published in the 3-year follow-up manuscript, and showed more MI in the PCI group than the protocol definition, the EACTS withdrew its support for the guidelines. The ESC continued to uphold the guidelines «until there is robust scientific evidence (as opposed to allegations) indicating we should do otherwise,” said Ms. Casadei.
A spokesperson for NEJM said the journal stood by the EXCEL papers because “there is no credible harm to patients from the publication of the paper and accurate reporting of trial results.” NEJM has since conducted a review and published a series of letters in response. The letters have reinvigorated rather than appeased the dissenters, as reported by Medscape.
A number of cardiologists and researchers started a petition on change.org to revise the EACTS/ESC left main CAD guidelines, and surgical societies across the globe have written to the editor of NEJM asking him to retract or amend the EXCEL papers.
This has not happened. The journal’s editor maintains that the letters containing the analyses are “sufficient information” to allow readers and guideline authors to “evaluate the trial findings.”
Dr. Taggart was dismissive of that response. “There is still no recognition or acknowledgment that failure to publish these data in 2016 ‘misled’ the guideline writers for the ESC/EACTS guidelines, and there is still no formal correction of the 2016 and 2019 NEJM manuscripts.”
Over a year after the BBC received the leaked data, the EXCEL investigators published an analysis of the primary outcome using the universal definition of MI data in the Journal of the American College of Cardiology.
It shows 141 events in the PCI arm, compared with 102 in the CABG arm. The investigators acknowledge that the rates of procedural MI differ depending on the definition used. According to their analysis, the protocol definition was predictive of mortality after both treatments, whereas the universal definition of procedural MI was predictive of mortality only after CABG. Not everyone agrees with this interpretation, and an accompanying editorial questioned these conclusions.
For Dr. Wallentin, it’s a relief that these data are in the public domain so that their interpretation and clinical consequences can be “openly discussed.” He hoped that the whole experience will result in something constructive and useful for the future.
As for the guidelines, the tide may be turning.
In a joint statement with EACTS on Oct. 6, 2020, the ESC agreed to review its guidelines for left main disease in the light of emerging, longer-term outcome data from the trials of CABG versus PCI.
Dr. Taggart has no regrets about speaking out despite this being “an exceedingly painful and bruising experience.”
The saga, he said, “reflects very badly on our specialty, the investigators, industry, and the world’s ‘leading’ medical journal.”

'Cardio-obstetrics' tied to better outcome in pregnancy with CVD
A multidisciplinary cardio-obstetrics team-based care model may help improve cardiovascular care for pregnant women with cardiovascular disease (CVD), according to a recent study.
“We sought to describe clinical characteristics, maternal and fetal outcomes, and cardiovascular readmissions in a cohort of pregnant women with underlying CVD followed by a cardio-obstetrics team,” wrote Ella Magun, MD, of Columbia University, New York, and coauthors. Their report is in the Journal of the American College of Cardiology.
The researchers reported the outcomes of a retrospective cohort analysis involving 306 pregnant women with CVD, who were treated at a quaternary care hospital in New York City.
They defined cardio-obstetrics as a team-based collaborative approach to maternal care that includes maternal fetal medicine, cardiology, anesthesiology, neonatology, nursing, social work, and pharmacy.
More than half of the women in the cohort (53%) were Hispanic and Latino, and 74% were receiving Medicaid, suggesting low socioeconomic status. Key outcomes of interest were cardiovascular readmissions at 30 days, 90 days, and 1 year. Secondary endpoints included maternal death, need for a left ventricular assist device or heart transplantation, and fetal demise.
The most frequently observed forms of CVD were arrhythmias (29%), cardiomyopathy (24%), congenital heart disease (24%), valvular disease (16%), and coronary artery disease (4%). The median Cardiac Disease in Pregnancy (CARPREG II) score was 3, and 43% of women had a CARPREG II score of 4 or higher.
After a median follow-up of 2.6 years, the 30-day and 90-day cardiovascular readmission rates were 1.9% and 4.6%, which was lower than the national 30-day postpartum rate of readmission (3.6%). One maternal death (0.3%) occurred within a year of delivery (woman with Eisenmenger syndrome).
“Despite high CARPREG II scores in this patient population, we found low rates of maternal and fetal complications with a low rate of 30- and 90-day readmissions following delivery,” the researchers wrote.
Experts weigh in
“We’re seeing widely increasing interest in the implementation of cardio-obstetrics models for multidisciplinary collaborative care and initial studies suggest these team-based models improve pregnancy and postpartum outcomes for women with cardiac disease,” said Lisa M. Hollier, MD, past president of the American College of Obstetricians and Gynecologists and professor at Baylor College of Medicine in Houston.
Dr. Magun and colleagues acknowledged that a key limitation of the present study was the retrospective, single-center design.
“With program expansions over the next 2-3 years, I expect to see an increasing number of prospective studies with larger sample sizes evaluating the impact of cardio-obstetrics teams on maternal morbidity and mortality,” Dr. Hollier said.

In an editorial accompanying the reports, Pamela Ouyang, MBBS, and Garima Sharma, MD, wrote that, although this study wasn’t designed to assess the benefit of cardio-obstetric teams relative to standard of care, its implementation of a multidisciplinary team-based care model showed excellent long-term outcomes.
The importance of coordinated postpartum follow-up with both cardiologists and obstetricians is becoming increasingly recognized, especially for women with poor pregnancy outcomes and with CVD that arises during pregnancy, such as pregnancy-associated spontaneous coronary artery dissection and peripartum cardiomyopathy, wrote Dr. Ouyang and Dr. Sharma, both with Johns Hopkins University in Baltimore.

A multidisciplinary cardio-obstetrics team-based care model may help improve cardiovascular care for pregnant women with cardiovascular disease (CVD), according to a recent study.
“We sought to describe clinical characteristics, maternal and fetal outcomes, and cardiovascular readmissions in a cohort of pregnant women with underlying CVD followed by a cardio-obstetrics team,” wrote Ella Magun, MD, of Columbia University, New York, and coauthors. Their report is in the Journal of the American College of Cardiology.
The researchers reported the outcomes of a retrospective cohort analysis involving 306 pregnant women with CVD, who were treated at a quaternary care hospital in New York City.
They defined cardio-obstetrics as a team-based collaborative approach to maternal care that includes maternal fetal medicine, cardiology, anesthesiology, neonatology, nursing, social work, and pharmacy.
More than half of the women in the cohort (53%) were Hispanic and Latino, and 74% were receiving Medicaid, suggesting low socioeconomic status. Key outcomes of interest were cardiovascular readmissions at 30 days, 90 days, and 1 year. Secondary endpoints included maternal death, need for a left ventricular assist device or heart transplantation, and fetal demise.
The most frequently observed forms of CVD were arrhythmias (29%), cardiomyopathy (24%), congenital heart disease (24%), valvular disease (16%), and coronary artery disease (4%). The median Cardiac Disease in Pregnancy (CARPREG II) score was 3, and 43% of women had a CARPREG II score of 4 or higher.
After a median follow-up of 2.6 years, the 30-day and 90-day cardiovascular readmission rates were 1.9% and 4.6%, which was lower than the national 30-day postpartum rate of readmission (3.6%). One maternal death (0.3%) occurred within a year of delivery (woman with Eisenmenger syndrome).
“Despite high CARPREG II scores in this patient population, we found low rates of maternal and fetal complications with a low rate of 30- and 90-day readmissions following delivery,” the researchers wrote.
Experts weigh in
“We’re seeing widely increasing interest in the implementation of cardio-obstetrics models for multidisciplinary collaborative care and initial studies suggest these team-based models improve pregnancy and postpartum outcomes for women with cardiac disease,” said Lisa M. Hollier, MD, past president of the American College of Obstetricians and Gynecologists and professor at Baylor College of Medicine in Houston.
Dr. Magun and colleagues acknowledged that a key limitation of the present study was the retrospective, single-center design.
“With program expansions over the next 2-3 years, I expect to see an increasing number of prospective studies with larger sample sizes evaluating the impact of cardio-obstetrics teams on maternal morbidity and mortality,” Dr. Hollier said.
“These findings suggest that our cardio-obstetrics program may help provide improved cardiovascular care to an otherwise underserved population,” the authors concluded.
