Study gives bleeding risk estimates for VTE patients on anticoagulants
The meta-analysis of data from 27 studies with 17,202 patients was published in the Annals of Internal Medicine. According to two of the paper’s coauthors, Faizan Khan, MSc, and Marc A. Rodger, MD, it “provides best available estimates of long-term bleeding risk with different anticoagulants in patients with unprovoked VTE,” including subgroups at increased risk.
Patients at increased risk for major bleeding include those who are older; those using antiplatelet therapy; and patients with kidney disease, a history of bleeding, or anemia, noted the coauthors, who work for the Ottawa Hospital Research Institute.
The researchers focused on randomized controlled trials (RCTs) and prospective cohort studies that reported major bleeding among patients with a first unprovoked or weakly provoked VTE who received oral anticoagulation for at least 6 months beyond an initial anticoagulant treatment course of at least 3 months.
The investigators analyzed data from 14 RCTs and 13 cohort studies. In all, 9,982 patients received a vitamin K antagonist (VKA), and 7,220 received a direct oral anticoagulant (DOAC).
The incidence of major bleeding per 100 person-years was 1.7 events with VKAs, compared with 1.1 events with DOACs. The researchers estimated that the 5-year cumulative incidence of major bleeding with VKAs was 6.3%. The available data for DOACs were insufficient to estimate the incidence of major bleeding beyond 1 year.
“This information can help clinicians counsel patients and inform shared decision-making about extended therapy,” the researchers said.
Risks of serious bleeding ‘not trivial’
Margaret Fang, MD, with the University of California, San Francisco, agreed that the study can help clinicians and patients weigh the risks of extended anticoagulation for common types of VTE.
The study also “highlights that the risks of serious bleeding are not trivial” and points out gaps in the literature regarding the long-term use of DOACs for extended VTE therapy, Dr. Fang said.
Better ways to predict which patients will develop bleeding on anticoagulants are needed, Dr. Fang added. “It will also be important to establish which of the various therapies for preventing recurrent VTE – full dose versus lowered dose, or even aspirin – has the best balance of safety and efficacy,” she said.
‘Standardized approach’ for identifying high-risk patients lacking
Clinical practice guidelines recommend indefinite anticoagulation for an unprovoked VTE, except when patients are at high risk of bleeding, the authors noted. But clinicians lack a “standardized approach to identify patients at high risk of bleeding,” Mr. Khan and Dr. Rodger said. “Evidence from randomized trials on net long-term benefit of extended therapy is limited, and current guideline recommendations are largely based on expert consensus opinion. Major bleeding events are two to three times more likely to be fatal than recurrent VTE events, so extended therapy is not always associated with a net mortality benefit, particularly in patients at low risk of recurrent VTE or high risk of bleeding.”
The analysis indicates that there is “a clinically meaningful difference in long-term risk for anticoagulant-related major bleeding among patients with a first unprovoked VTE stratified according to presence or absence of the following risk factors: age older than 65 years, creatinine clearance less than 50 mL/min, history of bleeding, concomitant use of antiplatelet therapy, and hemoglobin level less than 100 g/L,” the authors said.
For example, the researchers found that the incidence of major bleeding was higher among those older than 65 years, compared with younger patients (incidence rate ratio, 1.84 with VKAs and 2.92 with DOACs), and among those with creatinine clearance less than 50 mL/min (IRR, 2.83 with VKAs and 3.71 with DOACs).
The case-fatality rate of major bleeding was 8.3% with VKAs and 9.7% with DOACs.
The study received funding from the Canadian Institutes of Health Research. Some of the coauthors are employees of or have financial ties to pharmaceutical companies. Mr. Khan, Dr. Rodger, and Dr. Fang had no relevant disclosures.

Feds slap UPMC, lead cardiothoracic surgeon with fraud lawsuit
Following a 2-year investigation, the U.S. government has filed suit against the University of Pittsburgh Medical Center (UPMC), University of Pittsburgh Physicians (UPP), and James Luketich, MD, for billing related to concurrent surgeries performed by the long-time chair of cardiothoracic surgery.
The lawsuit alleges that UPMC “knowingly allowed” Dr. Luketich to “book and perform three surgeries at the same time, to miss the surgical time outs at the outset of those procedures, to go back-and-forth between operating rooms and even hospital facilities while his surgical patients remain under general anesthesia...”
UPMC, the lawsuit claims, also allowed Dr. Luketich to falsely attest that “he was with his patients throughout the entirety of their surgical procedures or during all ‘key and critical’ portions of those procedures and to unlawfully bill Government Health Benefit Programs for those procedures, all in order to increase surgical volume, maximize UPMC and UPP’s revenue, and/or appease Dr. Luketich.”
These practices violate the statutes and regulations governing the defendants, including those that prohibit “teaching physicians” like Dr. Luketich from performing and billing the U.S. for concurrent surgeries, the Department of Justice said in news release.
The Justice Department contends the defendants “knowingly submitted hundreds of materially false claims for payment” to Medicare, Medicaid, and other government programs over the past 6 years.
“The laws prohibiting ‘concurrent surgeries’ are in place for a reason: To protect patients and ensure they receive appropriate and focused medical care,” Stephen R. Kaufman, Acting U.S. Attorney for the Western District of Pennsylvania, said in the release.
According to the lawsuit, “some of Dr. Luketich’s patients were forced to endure additional surgical procedures and/or extended hospital stays as a result of his unlawful conduct. Numerous patients developed painful pressure ulcers. A few were diagnosed with compartment syndrome. And at least two had to undergo amputations.”
The allegations were originally brought forward under the federal False Claims Act’s whistleblower provisions by Jonathan D’Cunha, MD, PhD, who worked closely with Dr. Luketich from 2012 to 2019 and now chairs the department of cardiothoracic surgery at the Mayo Clinic, Phoenix.
The charges cited in the lawsuit include three counts of violating the False Claims Act, one count of unjust enrichment, and one count of payment by mistake.
The 56-page lawsuit includes numerous case examples and cites an October 2015 Boston Globe Spotlight Team report on the safety of running concurrent operations, which reportedly prompted UPMC to reevaluate its policies and identify physicians or departments in potential violation.
Hospital officials met with Dr. Luketich in March 2016 and devised a “plan” to ensure his availability and “compliance with concurrency rules,” it alleges, but also highlights an email that notes “continued problems” with Dr. Luketich’s schedule.
“UPMC has persistently ignored or minimized complaints by employees and staff regarding Dr. Luketich, his hyper-busy schedule, his refusal to delegate surgeries and surgical tasks” and “protected him from meaningful sanction; refused to curtail his surgical practice; and continued to allow Dr. Luketich to skirt the rules and endanger his patients,” according to the lawsuit.
The suit notes that Dr. Luketich is one of UPMC and UPP’s highest sources of revenue and that UPMC advertises him as a “life-saving pioneer” who routinely performs dramatic, last-ditch procedures on patients who are otherwise hopeless.
In response to an interview request from this news organization, a UPMC spokesperson wrote: “As the government itself concedes in its complaint, many of Dr. Luketich’s surgical patients are elderly, frail, and/or very ill. They include the ‘hopeless’ patients ... who suffer from chronic illness or metastatic cancer, and/or have extensive surgical histories and choose UPMC and Dr. Luketich when other physicians and health care providers have turned them down.”
“Dr. Luketich always performs the most critical portions of every operation he undertakes,” the spokesperson said, adding that no law or regulation prohibits overlapping surgeries or billing for those surgeries, “let alone surgeries conducted by teams of surgeons like those led by Dr. Luketich.”
“The government’s claims are, rather, based on a misapplication or misinterpretation of UPMC’s internal policies and [Centers for Medicare & Medicaid Services] guidance, neither of which can support a claim for fraudulent billing. UPMC and Dr. Luketich plan to vigorously defend against the government’s claims,” the spokesperson concluded.
The claims asserted against the defendants are allegations only; there has been no determination of liability. The government is seeking three times the amount of actual damages suffered as a result of the alleged false claims and/or fraud; a sum of $23,331 (or the maximum penalty, whichever is greater) for each false claim submitted by UPMC, UPP, and/or Dr. Luketich; and costs and expenses associated with the civil suit.

Case: Patient with statin-associated muscle symptoms
A 66-year-old woman is discharged from the hospital after an MI. Her discharge medications include atorvastatin 40 mg, lisinopril 20 mg, acetylsalicylic acid 81 mg, and clopidogrel 75 mg. At this patient’s follow-up appointment, she mentions that she has muscle pain and stiffness in both legs and her back. Her labs include thyroid-stimulating hormone of 2.0 and vitamin D of 40. She stops the atorvastatin for 2 weeks with resolution of her symptoms.
Which treatment recommendation would you make for this patient?
A. Restart atorvastatin
B. Start rosuvastatin twice a week
C. Start ezetimibe
D. Start a PCSK9 inhibitor
We often see high-risk cardiovascular disease patients who are concerned about muscle side effects brought on by statins. I think we all can agree that this patient needs aggressive medical therapy for prevention of secondary cardiovascular events. I would restart her atorvastatin.
Neilsen and Nordestgaard found that early statin discontinuation rates increased from 6% in 1995 to 18% in 2010.1
Early statin discontinuation correlated with negative statin-related news stories, their paper states. This suggests either an increased awareness of side effects or a possible nocebo effect.
Statin rechallenge results
Joy and colleagues reported the results on eight patients who had developed myalgias within 3 weeks of starting a statin. These patients, who received placebo or statin, completed an N-of-1 trial with three double-blind, crossover comparisons separated by 3-week washout periods.
Patients were evaluated pain on a visual analog scale (VAS). For each N-of-1 trial there was no statistically significant difference in pain or myalgia score between those who took statin and placebo. Five of the eight patients chose to continue on statins at the end of the trial.
Herrett and colleagues performed a more extensive series of N-of-1 trials involving 200 patients who had stopped or were considering stopping statins because of muscle symptoms.3 Participants either received 2 months of atorvastatin 20 mg or placebo for 2-month blocks six times. They rated their muscle symptoms on a VAS at the end of each block. There was no difference in muscle symptom scores between the statin and placebo periods.
Wood and colleagues took it a step further, when they studied an N-of-1 trial that included statin, placebo, and no treatment.4 Each participant received four bottles of atorvastatin 20 mg, four bottles of placebo, and four empty bottles. Each month they used treatment from the bottles based on random sequence and reported daily symptom scores. The mean symptom intensity was 8.0 during no-tablet months, 15.4 during placebo months (P < .001, compared with no-tablet months), and 16.3 during statin months (P < .001, compared with no-tablet months; P = .39, compared with placebo).
Taylor and colleagues studied 120 patients who had prior statin-associated muscle complaints.5 Each patient received either simvastatin 20 mg or placebo for 4 weeks, and then were switched for an additional 4 weeks. A total of 43 patients (36%) had pain on simvastatin but not placebo, 21 (17%) had no pain with either treatment, 21 (17%) reported pain with both treatments, and 35 (29%) had pain with placebo but not simvastatin. These studies support the concept of nocebo effect in patients who have muscle symptoms on statins.
So what should be done? Brennan and Roy did a retrospective study of 118 patients referred to a lipid clinic as being statin intolerant to two or more statins.6 Most of the patients were able to tolerate a statin: 71% tolerated same statin rechallenge, 53% tolerated statin switch, and 57% tolerated a nonstatin therapy.
In the Prosisa study, only 27% of patients who reported statin-associated muscle symptoms had reappearance of muscle symptoms after rechallenge with a statin.7
Research implications
Rechallenge with the same statin seems to be a reasonable first step, followed by switching to a different statin. I also share the concept of nocebo effect with my patients, and tell them I believe they have an excellent chance of tolerating the statin.
Pearl: The majority of patients with muscle symptoms while taking a statin likely have a nocebo effect, and are likely to tolerate rechallenge with the same statin.

Taylor and colleagues studied 120 patients who had prior statin-associated muscle complaints.5 Each patient received either simvastatin 20 mg or placebo for 4 weeks, and then were switched for an additional 4 weeks. A total of 43 patients (36%) had pain on simvastatin but not placebo, 21 (17%) had no pain with either treatment, 21 (17%) reported pain with both treatments, and 35 (29%) had pain with placebo but not simvastatin. These studies support the concept of nocebo effect in patients who have muscle symptoms on statins.
So what should be done? Brennan and Roy did a retrospective study of 118 patients referred to a lipid clinic as being statin intolerant to two or more statins.6 Most of the patients were able to tolerate a statin: 71% tolerated same statin rechallenge, 53% tolerated statin switch, and 57% tolerated a nonstatin therapy.
In the Prosisa study, only 27% of patients who reported statin-associated muscle symptoms had reappearance of muscle symptoms after rechallenge with a statin.7
Research implications
Rechallenge with the same statin seems to be a reasonable first step, followed by switching to a different statin. I also share the concept of nocebo effect with my patients, and tell them I believe they have an excellent chance of tolerating the statin.
Pearl: The majority of patients with muscle symptoms while taking a statin likely have a nocebo effect, and are likely to tolerate rechallenge with the same statin.

A 66-year-old woman is discharged from the hospital after an MI. Her discharge medications include atorvastatin 40 mg, lisinopril 20 mg, acetylsalicylic acid 81 mg, and clopidogrel 75 mg. At this patient’s follow-up appointment, she mentions that she has muscle pain and stiffness in both legs and her back. Her labs include thyroid-stimulating hormone of 2.0 and vitamin D of 40. She stops the atorvastatin for 2 weeks with resolution of her symptoms.
Which treatment recommendation would you make for this patient?
A. Restart atorvastatin
B. Start rosuvastatin twice a week
C. Start ezetimibe
D. Start a PCSK9 inhibitor
We often see high-risk cardiovascular disease patients who are concerned about muscle side effects brought on by statins. I think we all can agree that this patient needs aggressive medical therapy for prevention of secondary cardiovascular events. I would restart her atorvastatin.
Neilsen and Nordestgaard found that early statin discontinuation rates increased from 6% in 1995 to 18% in 2010.1
Early statin discontinuation correlated with negative statin-related news stories, their paper states. This suggests either an increased awareness of side effects or a possible nocebo effect.
Statin rechallenge results
Joy and colleagues reported the results on eight patients who had developed myalgias within 3 weeks of starting a statin. These patients, who received placebo or statin, completed an N-of-1 trial with three double-blind, crossover comparisons separated by 3-week washout periods.
Patients were evaluated pain on a visual analog scale (VAS). For each N-of-1 trial there was no statistically significant difference in pain or myalgia score between those who took statin and placebo. Five of the eight patients chose to continue on statins at the end of the trial.
Herrett and colleagues performed a more extensive series of N-of-1 trials involving 200 patients who had stopped or were considering stopping statins because of muscle symptoms.3 Participants either received 2 months of atorvastatin 20 mg or placebo for 2-month blocks six times. They rated their muscle symptoms on a VAS at the end of each block. There was no difference in muscle symptom scores between the statin and placebo periods.
Wood and colleagues took it a step further, when they studied an N-of-1 trial that included statin, placebo, and no treatment.4 Each participant received four bottles of atorvastatin 20 mg, four bottles of placebo, and four empty bottles. Each month they used treatment from the bottles based on random sequence and reported daily symptom scores. The mean symptom intensity was 8.0 during no-tablet months, 15.4 during placebo months (P < .001, compared with no-tablet months), and 16.3 during statin months (P < .001, compared with no-tablet months; P = .39, compared with placebo).

‘Quadpill’ bests monotherapy for initial BP lowering: QUARTET
A “quadpill” containing quarter doses of four blood pressure (BP)–lowering medications was more effective than monotherapy for initial treatment of hypertension, with similar tolerability, in the 1-year, phase 3 QUARTET randomized, active-control trial.
Clara Chow, MD, PhD, academic director of the Westmead Applied Research Centre, University of Sydney, presented the findings in a late-breaking trial session at the annual congress of the European Society of Cardiology. The study was simultaneously published in The Lancet.
The primary outcome, mean unattended office BP at 12 weeks, dropped from 142/86 mm Hg to 120/71 mm Hg in patients who received the daily quadpill – a capsule containing irbesartan, amlodipine, indapamide, and bisoprolol – and fell from 140/83 mm Hg to 127/79 mm Hg in patients who received a daily full dose of irbesartan.
This 6.9 mm Hg greater drop in systolic BP at 12 months is clinically meaningful, Dr. Chow told this news organization. “If maintained, it would be expected to confer about a 15%-20% reduction” in heart disease, stroke, and heart failure.
In the SPRINT study, she noted, the final systolic BP was 120 mm Hg in the intervention group and 134 mm Hg in the control group, and the difference was associated with a 27% reduction in the composite cardiovascular (CV) outcome.
The results of QUARTET suggest that, “even in those with stage 1 hypertension, we can safely reduce BP to a significant degree by this simple approach, compared to usual care,” Salim Yusuf, MD, DPhil, a long-time advocate of a polypill approach, said in an email.
Importantly, Dr. Chow pointed out, at 12 months, 81% of patients treated with the quadpill versus 62% of patients treated with monotherapy had BP control (<140/90 mm Hg). Patients who received monotherapy did not “catch up,” even though a higher percentage received stepped-up therapy.
The quadpill dosing strategy aligns with the latest 2018 ESC/European Society of Hypertension guidelines, which recommend starting antihypertensive treatment with more than one drug, session cochair Thomas Kahan, MD, PhD, Karolinska Institute, Danderyd Hospital, department of clinical sciences, Stockholm, commented.
“How many drugs should be in the initial step?” he asked. “Is four better than three or two, or should we have even more drugs at low doses?”
The trial was not designed to answer these questions, Dr. Chow replied. “We were really comparing [the quadpill] against what the majority of people around the planet are still doing, which is starting on one drug and slowly but surely stepping it up,” she said.
The quadpill was actually a capsule, she clarified, that contained four generic BP medications available in half doses in Australia. The half doses were cut in half and the medications were encapsulated. The control drug was prepared in an identical-looking capsule.
It is important to note that “the time to BP control was shorter in patients who received the quadpill versus monotherapy,” session cochair Felix Mahfoud, MD, internal medicine and cardiology, Saarland University Hospital, Hamburg, Germany, pointed out, because “in clinical practice we aim to get patients to BP control as quickly as possible.”
“What is new here is the use of four drugs, each given at quarter doses,” Dr. Yusuf, director of the Population Health Research Institute, McMaster University, Hamilton, Ont., said. Although a few questions remain, “this study emphasizes the importance and potential benefits and simplicity of using combination BP-lowering drugs at low doses.”
For guidelines to be changed, he observed, the findings would have to be replicated in independent studies, and the quadpill would likely have to be shown to be superior to the dual pill.
“It took about 20 years [to change guidelines] after the first evidence that combinations of two pills were preferable to single-drug combinations,” he noted.
“I hope that in most people with elevated BP, at least a two-drug combination plus a statin plus aspirin will be prescribed,” Dr. Yusuf said. “This can reduce the risk of CVD events by 50% or more – a big impact both for the individual and for populations. The quad pill may have a role in this approach.”
Four-in-one pill
Worldwide, hypertension control is poor, Dr. Chow said, because of the need for multiple medications, treatment inertia, and concerns about adverse events.
The researchers hypothesized that initial antihypertensive treatment with a four-in-one pill with quarter doses of each medication would minimize side effects, maximize BP lowering, and overcome these treatment barriers and concerns. A pilot study of this strategy published by the group in 2017 showed promise.
QUARTET randomized 591 adults with hypertension, seen at clinics in four states in Australia from June 2017 through August 2020.
Patients were either receiving no antihypertensive medication and had an unattended standard office BP of 140/90 to 179/109 mm Hg or daytime ambulatory BP greater than 135/95 mm Hg, or they were on BP-lowering monotherapy and had a BP of 130/85 to 179/109 mm Hg or daytime ambulatory BP greater than 125/80 mm Hg. Patients who were taking antihypertensive therapy entered a washout period before the trial.
The researchers randomized 291 participants to receive 150 mg irbesartan daily (usual care or control group).
The other 300 participants received a daily quadpill containing 37.5 mg irbesartan, 1.25 mg amlodipine, 0.625 mg indapamide, and 2.5 mg bisoprolol. The first three drugs are the most commonly prescribed angiotensin II receptor blocker, calcium channel blocker, and thiazide or thiazidelike diuretic in Australia, and the last drug, a beta-blocker, has a long duration of action, the study protocol explains.
Patients in both groups had similar baseline characteristics. They were a mean age of 58 years, 40% were women, and 82% were White. They also had a mean body mass index of 31 kg/m2. About 8% were current smokers, and about 54% were not taking a BP-lowering drug.
Participants had clinic visits at baseline, 6 weeks, and 12 weeks, and if they continued the study, at 26 weeks and 52 weeks.
If a patient’s blood pressure was higher than 140/90 mm Hg, clinicians could add another medication, starting with amlodipine 5 mg.
At 12 weeks, 15% of patients in the intervention group and 40% in the control group had stepped up treatment.
Despite greater up-titration in the usual care group, BP control remained higher in the quadpill group, Dr. Chow pointed out. That is, patients in the quadpill group were more likely than patients in the usual care group to have a BP less than 140/90 mm Hg (76% vs. 58% respectively; P < .0001).
Patients in the quadpill group also had lower daytime and nighttime ambulatory systolic BP.
At 12 months, among the 417 patients who continued treatment, patients in the quadpill group had a 7.7 mm Hg greater drop in systolic BP, compared with patients in the control group, (P < .001).
There were no significant differences in adverse events, which were most commonly dizziness (31% and 25%) or muscle cramps, gastrointestinal complaints, headache, or musculoskeletal complaints.
At 12 weeks, there were seven serious adverse events in the intervention group versus three in the control group. There were 12 treatment withdrawals in the intervention group versus seven in the control group (P = .27).
Remaining questions, upcoming phase 3 U.S. study
“While the [QUARTET] results are impressive, we are left with a number of questions,” Dr. Yusuf said.
Would the results be the same with a three-drug combo or even a two-drug combo at half doses? In the HOPE 3 trial, a two-drug combo at half doses provided similar results to the current study, over a much longer mean follow-up of 5.6 years, he noted.
Also, is the quadpill associated with higher rates of diabetes or higher creatinine levels in the long term? “Given that we do not have any data on long-term clinical outcomes from a four-drug combination,” Dr. Yusuf said, “caution should be utilized.”
Would the reduced risk of CVD be greater with a combination of low doses of two BP-lowering drugs plus a statin plus aspirin? That may be superior, he said, “based on recent information published on the polypill indicating a 50% relative risk reduction in CVD events.”
The related phase 2 QUARTET US trial should shed further light on a quadpill strategy. Patients with hypertension are being randomized to a daily quadpill containing 2 mg candesartan, 1.25 mg amlodipine besylate, 0.625 mg indapamide, and 2.5 mg bisoprolol, or to usual care, 8 mg candesartan daily.
Investigators plan to enroll 87 participants in the Chicago area, with estimated study completion by March 31, 2023.
The study was supported by an Australian National Health and Medical Research Council grant. The George Institute for Global Health has submitted patent applications for low–fixed-dose combination products to treat CV or cardiometabolic disease. Dr. Chow and coauthor Kris Rogers, PhD, senior biostatistician at The George Institute for Global Health, Newtown, Australia, are listed as inventors, but they do not have direct financial interests in these patent applications.

Despite greater up-titration in the usual care group, BP control remained higher in the quadpill group, Dr. Chow pointed out. That is, patients in the quadpill group were more likely than patients in the usual care group to have a BP less than 140/90 mm Hg (76% vs. 58% respectively; P < .0001).
Patients in the quadpill group also had lower daytime and nighttime ambulatory systolic BP.
At 12 months, among the 417 patients who continued treatment, patients in the quadpill group had a 7.7 mm Hg greater drop in systolic BP, compared with patients in the control group, (P < .001).
There were no significant differences in adverse events, which were most commonly dizziness (31% and 25%) or muscle cramps, gastrointestinal complaints, headache, or musculoskeletal complaints.
At 12 weeks, there were seven serious adverse events in the intervention group versus three in the control group. There were 12 treatment withdrawals in the intervention group versus seven in the control group (P = .27).
Remaining questions, upcoming phase 3 U.S. study
“While the [QUARTET] results are impressive, we are left with a number of questions,” Dr. Yusuf said.
Would the results be the same with a three-drug combo or even a two-drug combo at half doses? In the HOPE 3 trial, a two-drug combo at half doses provided similar results to the current study, over a much longer mean follow-up of 5.6 years, he noted.
Also, is the quadpill associated with higher rates of diabetes or higher creatinine levels in the long term? “Given that we do not have any data on long-term clinical outcomes from a four-drug combination,” Dr. Yusuf said, “caution should be utilized.”
Would the reduced risk of CVD be greater with a combination of low doses of two BP-lowering drugs plus a statin plus aspirin? That may be superior, he said, “based on recent information published on the polypill indicating a 50% relative risk reduction in CVD events.”
The related phase 2 QUARTET US trial should shed further light on a quadpill strategy. Patients with hypertension are being randomized to a daily quadpill containing 2 mg candesartan, 1.25 mg amlodipine besylate, 0.625 mg indapamide, and 2.5 mg bisoprolol, or to usual care, 8 mg candesartan daily.
Investigators plan to enroll 87 participants in the Chicago area, with estimated study completion by March 31, 2023.
The study was supported by an Australian National Health and Medical Research Council grant. The George Institute for Global Health has submitted patent applications for low–fixed-dose combination products to treat CV or cardiometabolic disease. Dr. Chow and coauthor Kris Rogers, PhD, senior biostatistician at The George Institute for Global Health, Newtown, Australia, are listed as inventors, but they do not have direct financial interests in these patent applications.

Growing proportion of cardiac arrests in U.S. considered opioid related
Observational data indicate that the number of hospitalizations for cardiac arrests linked to opioid use roughly doubled from 2012 to 2018.
“This was an observational study, so we cannot conclude that all of the arrests were caused by opioids, but the findings do suggest the opioid epidemic is a contributor to increasing rates,” Senada S. Malik, of the University of New England, Portland, Maine, reported at the virtual annual congress of the European Society of Cardiology.
The data were drawn from the Nationwide Inpatient Sample (NIS) from 2012 to 2018, the most recent period available. Cardiac arrests were considered opioid related if there was a secondary diagnosis of opioid disease. The rates of opioid-associated hospitalizations for these types of cardiac arrests climbed from about 800 per year in 2012 to 1,500 per year in 2018, a trend that was statistically significant (P < .05).
The profile of patients with an opioid-associated cardiac arrest was different from those without secondary diagnosis of opioid disease. This included a younger age and lower rates of comorbidities: heart failure (21.2% vs. 40.6%; P < .05), renal failure (14.3% vs. 30.2%; P < .05), diabetes (19.5% vs. 35.4%; P < .05), and hypertension (43.4% vs. 64.9%; P < .05).
Mortality from opioid-associated cardiac arrest is lower
These features might explain the lower rate of in-hospital mortality for opioid-associated cardiac arrests (56.7% vs. 61.2%), according to Ms. Malik, who performed this research in collaboration with Wilbert S. Aronow, MD, director of cardiology research, Westchester Medical Center, Valhalla, N.Y.
When compared to those without a history of opioid use on admission, those with opioid-associated cardiac arrest were more likely to be depressed (18.8% vs. 9.0%), to smoke (37.0% vs. 21.8%) and to abuse alcohol (16.9% vs. 7.1%), according to the NIS data.
While these findings are based on cardiac arrests brought to a hospital, some opioid-induced cardiac arrests never result in hospital admission, according to data included in a recently issued scientific statement from the American Heart Association.
Rate of opioid-associated cardiac arrests underestimated
In that statement, which was focused on opioid-associated out-of-hospital cardiac arrests (OA-OHCA), numerous studies were cited to support the conclusion that these events are common and underestimated. One problem is that opioid-induced cardiac arrests are not always accurately differentiated from cardiac arrests induced by use of other substances, such as barbiturates, cocaine, or alcohol.
For this and other reasons, the data are inconsistent. One study based on emergency medical service (EMS) response data concluded that 9% of all out-of-hospital cardiac arrests are opioid associated.
In another study using potentially more accurate autopsy data, 60% of the non–cardiac-associated cardiac arrests were found to occur in individuals with potentially lethal serum concentrations of opioids. As 40% of out-of-hospital cardiac arrests were considered non–cardiac related, this suggested that 15% of all out-of-hospital cardiac arrests are opioid related.
In the NIS data, the incident curves of opioid-related cardiac arrests appeared to be flattening in 2018, the last year of data collection, but there was no indication they were declining.
Patterns of opioid-induced cardiac arrests evolving
The patterns of opioid-induced cardiac arrest have changed and are likely to continue to change in response to the evolving opioid epidemic, according to the AHA scientific statement. The authors described three waves of opioid abuse. The first, which was related to the promotion of prescription opioids to treat chronic pain that ultimately led to high rates of opioid addiction, peaked in 2012 when rates of these prescriptions began to fall. At that time a second wave, attributed to patients switching to less expensive nonprescription heroin, was already underway. A third wave, attributed to growth in the use of synthetic opioids, such as fentanyl, began in 2013 and is ongoing, according to data cited in the AHA statement.
Recognizing the role of opioids in rising rates of cardiac arrest is important for promoting strategies of effective treatment and prevention, according to Cameron Dezfulian, MD, medical director of the adult congenital heart disease program at Texas Children’s Hospital, Houston. Dr. Dezfulian was vice chair and leader of the writing committee for the AHA scientific statement on OA-OHCA. He said there are plenty of data to support the need for greater attention to the role of opioids in cardiac arrest.
“The recent data affirms the trends many of us have observed without our emergency rooms and ICUs: a steady increase in the proportion of OA-OHCA, primarily in young and otherwise healthy individuals,” he said.
He calls not only for more awareness at the front lines of health are but also for a more comprehensive approach.
“Public health policies and community- and hospital-based interventions are needed to reduce the mortality due to OA-OHCA, which is distinct from the traditional cardiac etiology,” Dr. Dezfulian said.
In opioid-induced cardiac arrest, as in other types of cardiac arrest, prompt initiation of cardiopulmonary resuscitation is essential, but early administration of the opioid antagonist naloxone can also be lifesaving, according to treatment strategies outlined in the AHA scientific statement. The fact that OA-OHCA typically occur in patients with structurally and electrophysiologically normal hearts is emphasized in the AHA statement. So is the enormous public health toll of OA-OHCA.
Death due to opioid overdose, which includes cardiac arrests, is now the leading cause of mortality in the U.S. among individuals between the ages of 25 and 64 years, according to the statement.
Ms. Malik reports no potential conflicts of interest. Dr. Dezfulian reports a financial relationship with Mallinckrodt.

STOP-DAPT 2 ACS: 1 month of DAPT proves inadequate for patients with recent ACS
One month of dual antiplatelet therapy followed by 11 months of clopidogrel monotherapy failed to prove noninferiority to 12 unbroken months of DAPT for net clinical benefit in a multicenter Japanese trial that randomized more than 4,000 patients who underwent percutaneous coronary intervention (PCI) after a recent acute coronary syndrome episode.
The outcomes showed that while truncating DAPT duration could, as expected, cut major bleeding episodes roughly in half, it also led to a significant near doubling of myocardial infarction and showed a strong trend toward also increasing a composite tally of several types of ischemic events. These data were reported this week by Hirotoshi Watanabe, MD, PhD, at the virtual annual congress of the European Society of Cardiology. All study patients had undergone PCI with cobalt-chromium everolimus-eluting (CCEE) coronary stents (Xience).
These findings from the STOPDAPT-2 ACS trial highlighted the limits of minimizing DAPT after PCI in patients at high ischemic risk, such as after an acute coronary syndrome (ACS) event.
It also was a counterpoint to a somewhat similar study also reported at the congress, MASTER DAPT, which showed that 1 month of DAPT was noninferior to 3 or more months of DAPT for net clinical benefit in a distinctly different population of patients undergoing PCI (and using a different type of coronary stent) – those at high bleeding risk and with only about half the patients having had a recent ACS.
The results of STOPDAPT-2 ACS “do not support use of 1 month of DAPT followed by P2Y12 inhibitor monotherapy with clopidogrel compared with standard DAPT,” commented Robert A. Byrne, MBBCh, PhD, designated discussant for the report and professor at the RCSI University of Medicine and Health Sciences in Dublin.
“Although major bleeding was significantly reduced with this approach, there appeared to be a significant increase in adverse ischemic events, and there was a clear signal in relation to overall mortality, the ultimate arbiter of net clinical benefit,” added Dr. Byrne, who is also director of cardiology at Mater Private Hospital in Dublin.
He suggested that a mechanistic explanation for the signal of harm seem in STOPDAPT-2 ACS was the relatively low potency of clopidogrel (Plavix) as an antiplatelet agent, compared with other P2Y12 inhibitors such as prasugrel (Effient) and ticagrelor (Brilinta), as well as the genetically driven variability in response to clopidogrel that’s also absent with alternative agents.
These between-agent differences are of “particular clinical relevance in the early aftermath of an ACS event,” Dr. Byrne said.
12-month DAPT remains standard for PCI patients with recent ACS
The totality of clinical evidence “continues to support a standard 12-month duration of DAPT – using aspirin and either prasugrel or ticagrelor – as the preferred default approach,” Dr. Byrne concluded.
He acknowledged that an abbreviated duration of DAPT followed by P2Y12 inhibitor monotherapy “might be considered as an alternative.” In patients following an ACS event who do not have high risk for bleeding, he said, the minimum duration of DAPT should be at least 3 months and with preferential use of a more potent P2Y12 inhibitor.
Twelve months of DAPT treatment with aspirin and a P2Y12 inhibitor for patients following PCI “remains the standard of care in guidelines,” noted Marco Roffi, MD, a second discussant at the congress. But several questions remain, he added, such as which P2Y12 inhibitors work best and whether DAPT can be less than 12 months.
“The investigators [for STOPDAPT-2 ACS] pushed these questions to the limit with 1 month of DAPT and clopidogrel monotherapy,” said Dr. Roffi, professor and director of interventional cardiology at University Hospital, Geneva.
“This was a risky bet, and the investigators lost by not proving noninferiority and with excess ischemic events,” he commented.
First came STOPDAPT-2
Dr. Watanabe and colleagues designed STOPDAPT-2 ACS as a follow-up to their prior STOPDAPT-2 trial, which randomly assigned slightly more than 3000 patients at 90 Japanese centers to the identical two treatment options: 1 month of DAPT followed by 11 months of clopidogrel monotherapy or 12 months of DAPT, except the trial enrolled all types of patients undergoing PCI. This meant that a minority, 38%, had a recent ACS event, while the remaining patients had chronic coronary artery disease. As in STOPDAPT-2 ACS, all patients in STOPDAPT-2 had received a CCEE stent.
STOPDAPT-2 also used the same primary endpoint to tally net clinical benefit as STOPDAPT-2 ACS: cardiovascular death, MI, stroke of any type, definite stent thrombosis, or TIMI major or minor bleeding classification.
In STOPDAPT-2, using the mixed population with both recent ACS and chronic coronary disease, the regimen of 1 month of DAPT followed by 11 months of clopidogrel monotherapy was both noninferior to and superior to 12 months of DAPT, reducing the net adverse-event tally by 36% relative to 12-month DAPT and by an absolute reduction of 1.34%, as reported in 2019.
Despite this superiority, the results from STOPDAPT-2 had little impact on global practice, commented Kurt Huber, MD, professor and director of the cardiology ICU at the Medical University of Vienna.
“STOP-DAPT-2 did not give us a clear message with respect to reducing antiplatelet treatment after 1 month. I thought that for ACS patients 1 month might be too short,” Dr. Huber said during a press briefing.
Focusing on post-ACS
To directly address this issue, the investigators launched STOPDAPT-2 ACS, which used the same design as the preceding study but only enrolled patients soon after an ACS event. The trial included for its main analysis 3,008 newly enrolled patients with recent ACS, and 1,161 patients who had a recent ACS event and had been randomly assigned in STOPDAPT-2, creating a total study cohort for the new analysis of 4136 patients treated and followed for the study’s full 12 months.
The patients averaged 67 years old, 79% were men, and 30% had diabetes. About 56% had a recent ST-elevation MI, about 20% a recent non–ST-elevation MI, and the remaining 24% had unstable angina. For their unspecified P2Y12 inhibition, roughly half the patients received clopidogrel and the rest received prasugrel. Adherence to the two assigned treatment regimens was very good, with a very small number of patients not adhering to their assigned protocol.
The composite adverse event incidence over 12 months was 3.2% among those who received 1-month DAPT and 2.83% in those on DAPT for 12 months, a difference that failed to achieve the prespecified definition of noninferiority for 1-month DAPT, reported Dr. Watanabe, an interventional cardiologist at Kyoto University.
The ischemic event composite was 50% lower among those on 12-month DAPT, compared with 1 month of DAPT, a difference that just missed significance. The rate of MI was 91% higher with 1-month DAPT, compared with 12 months, a significant difference.
One-month DAPT also significantly reduced the primary measure of bleeding events – the combination of TIMI major and minor bleeds – by a significant 54%, compared with 12-month DAPT. A second metric of clinically meaningful bleeds, those that meet either the type 3 or 5 definition of the Bleeding Academic Research Consortium, were reduced by a significant 59% by 1-month DAPT, compared with 12 months of DAPT.
The new findings from STOPDAPT-2 ACS contrasted with those from MASTER DAPT, but in an explicable way that related to different patient types, different P2Y12 inhibitors, different treatment durations, and different stents.
“We’ve seen in MASTER DAPT that if you use the right stent and use ticagrelor for monotherapy there may be some ability to shorten DAPT, but we still do not know what would happen in patients with very high ischemic risk,” concluded Dr. Huber.
“A reduction in DAPT duration might work in patients without high bleeding risk, but I would exclude patients with very high ischemic risk,” he added. “I also can’t tell you whether 1 month or 3 months is the right approach, and I think clopidogrel is not the right drug to use for monotherapy after ACS.”
STOPDAPT-2 and STOPDAPT-2 ACS were both sponsored by Abbott Vascular, which markets the CCEE (Xience) stents used in both studies. Dr. Watanabe has received lecture fees from Abbott and from Daiichi-Sankyo. Dr. Byrne has received research funding from Abbott Vascular as well as from Biosensors, Biotronik, and Boston Scientific. Roffi has received research funding from Biotronik, Boston Scientific, GE Healthcare, Medtronic, and Terumo. Dr. Huber has received lecture fees from AstraZeneca, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Daiichi-Sankyo, Eli Lilly, Pfizer, Sanofi-Aventis, and The Medicines Company.

Despite this superiority, the results from STOPDAPT-2 had little impact on global practice, commented Kurt Huber, MD, professor and director of the cardiology ICU at the Medical University of Vienna.
“STOP-DAPT-2 did not give us a clear message with respect to reducing antiplatelet treatment after 1 month. I thought that for ACS patients 1 month might be too short,” Dr. Huber said during a press briefing.
Focusing on post-ACS
To directly address this issue, the investigators launched STOPDAPT-2 ACS, which used the same design as the preceding study but only enrolled patients soon after an ACS event. The trial included for its main analysis 3,008 newly enrolled patients with recent ACS, and 1,161 patients who had a recent ACS event and had been randomly assigned in STOPDAPT-2, creating a total study cohort for the new analysis of 4136 patients treated and followed for the study’s full 12 months.
The patients averaged 67 years old, 79% were men, and 30% had diabetes. About 56% had a recent ST-elevation MI, about 20% a recent non–ST-elevation MI, and the remaining 24% had unstable angina. For their unspecified P2Y12 inhibition, roughly half the patients received clopidogrel and the rest received prasugrel. Adherence to the two assigned treatment regimens was very good, with a very small number of patients not adhering to their assigned protocol.
The composite adverse event incidence over 12 months was 3.2% among those who received 1-month DAPT and 2.83% in those on DAPT for 12 months, a difference that failed to achieve the prespecified definition of noninferiority for 1-month DAPT, reported Dr. Watanabe, an interventional cardiologist at Kyoto University.
The ischemic event composite was 50% lower among those on 12-month DAPT, compared with 1 month of DAPT, a difference that just missed significance. The rate of MI was 91% higher with 1-month DAPT, compared with 12 months, a significant difference.
One-month DAPT also significantly reduced the primary measure of bleeding events – the combination of TIMI major and minor bleeds – by a significant 54%, compared with 12-month DAPT. A second metric of clinically meaningful bleeds, those that meet either the type 3 or 5 definition of the Bleeding Academic Research Consortium, were reduced by a significant 59% by 1-month DAPT, compared with 12 months of DAPT.
The new findings from STOPDAPT-2 ACS contrasted with those from MASTER DAPT, but in an explicable way that related to different patient types, different P2Y12 inhibitors, different treatment durations, and different stents.
“We’ve seen in MASTER DAPT that if you use the right stent and use ticagrelor for monotherapy there may be some ability to shorten DAPT, but we still do not know what would happen in patients with very high ischemic risk,” concluded Dr. Huber.
“A reduction in DAPT duration might work in patients without high bleeding risk, but I would exclude patients with very high ischemic risk,” he added. “I also can’t tell you whether 1 month or 3 months is the right approach, and I think clopidogrel is not the right drug to use for monotherapy after ACS.”
STOPDAPT-2 and STOPDAPT-2 ACS were both sponsored by Abbott Vascular, which markets the CCEE (Xience) stents used in both studies. Dr. Watanabe has received lecture fees from Abbott and from Daiichi-Sankyo. Dr. Byrne has received research funding from Abbott Vascular as well as from Biosensors, Biotronik, and Boston Scientific. Roffi has received research funding from Biotronik, Boston Scientific, GE Healthcare, Medtronic, and Terumo. Dr. Huber has received lecture fees from AstraZeneca, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Daiichi-Sankyo, Eli Lilly, Pfizer, Sanofi-Aventis, and The Medicines Company.

One month of dual antiplatelet therapy followed by 11 months of clopidogrel monotherapy failed to prove noninferiority to 12 unbroken months of DAPT for net clinical benefit in a multicenter Japanese trial that randomized more than 4,000 patients who underwent percutaneous coronary intervention (PCI) after a recent acute coronary syndrome episode.
The outcomes showed that while truncating DAPT duration could, as expected, cut major bleeding episodes roughly in half, it also led to a significant near doubling of myocardial infarction and showed a strong trend toward also increasing a composite tally of several types of ischemic events. These data were reported this week by Hirotoshi Watanabe, MD, PhD, at the virtual annual congress of the European Society of Cardiology. All study patients had undergone PCI with cobalt-chromium everolimus-eluting (CCEE) coronary stents (Xience).
These findings from the STOPDAPT-2 ACS trial highlighted the limits of minimizing DAPT after PCI in patients at high ischemic risk, such as after an acute coronary syndrome (ACS) event.
It also was a counterpoint to a somewhat similar study also reported at the congress, MASTER DAPT, which showed that 1 month of DAPT was noninferior to 3 or more months of DAPT for net clinical benefit in a distinctly different population of patients undergoing PCI (and using a different type of coronary stent) – those at high bleeding risk and with only about half the patients having had a recent ACS.
The results of STOPDAPT-2 ACS “do not support use of 1 month of DAPT followed by P2Y12 inhibitor monotherapy with clopidogrel compared with standard DAPT,” commented Robert A. Byrne, MBBCh, PhD, designated discussant for the report and professor at the RCSI University of Medicine and Health Sciences in Dublin.
“Although major bleeding was significantly reduced with this approach, there appeared to be a significant increase in adverse ischemic events, and there was a clear signal in relation to overall mortality, the ultimate arbiter of net clinical benefit,” added Dr. Byrne, who is also director of cardiology at Mater Private Hospital in Dublin.
He suggested that a mechanistic explanation for the signal of harm seem in STOPDAPT-2 ACS was the relatively low potency of clopidogrel (Plavix) as an antiplatelet agent, compared with other P2Y12 inhibitors such as prasugrel (Effient) and ticagrelor (Brilinta), as well as the genetically driven variability in response to clopidogrel that’s also absent with alternative agents.
These between-agent differences are of “particular clinical relevance in the early aftermath of an ACS event,” Dr. Byrne said.
12-month DAPT remains standard for PCI patients with recent ACS
The totality of clinical evidence “continues to support a standard 12-month duration of DAPT – using aspirin and either prasugrel or ticagrelor – as the preferred default approach,” Dr. Byrne concluded.
He acknowledged that an abbreviated duration of DAPT followed by P2Y12 inhibitor monotherapy “might be considered as an alternative.” In patients following an ACS event who do not have high risk for bleeding, he said, the minimum duration of DAPT should be at least 3 months and with preferential use of a more potent P2Y12 inhibitor.
Twelve months of DAPT treatment with aspirin and a P2Y12 inhibitor for patients following PCI “remains the standard of care in guidelines,” noted Marco Roffi, MD, a second discussant at the congress. But several questions remain, he added, such as which P2Y12 inhibitors work best and whether DAPT can be less than 12 months.
“The investigators [for STOPDAPT-2 ACS] pushed these questions to the limit with 1 month of DAPT and clopidogrel monotherapy,” said Dr. Roffi, professor and director of interventional cardiology at University Hospital, Geneva.
“This was a risky bet, and the investigators lost by not proving noninferiority and with excess ischemic events,” he commented.
First came STOPDAPT-2
Dr. Watanabe and colleagues designed STOPDAPT-2 ACS as a follow-up to their prior STOPDAPT-2 trial, which randomly assigned slightly more than 3000 patients at 90 Japanese centers to the identical two treatment options: 1 month of DAPT followed by 11 months of clopidogrel monotherapy or 12 months of DAPT, except the trial enrolled all types of patients undergoing PCI. This meant that a minority, 38%, had a recent ACS event, while the remaining patients had chronic coronary artery disease. As in STOPDAPT-2 ACS, all patients in STOPDAPT-2 had received a CCEE stent.
STOPDAPT-2 also used the same primary endpoint to tally net clinical benefit as STOPDAPT-2 ACS: cardiovascular death, MI, stroke of any type, definite stent thrombosis, or TIMI major or minor bleeding classification.
In STOPDAPT-2, using the mixed population with both recent ACS and chronic coronary disease, the regimen of 1 month of DAPT followed by 11 months of clopidogrel monotherapy was both noninferior to and superior to 12 months of DAPT, reducing the net adverse-event tally by 36% relative to 12-month DAPT and by an absolute reduction of 1.34%, as reported in 2019.

New European guidelines on CVD prevention
The new guidelines were published online Aug. 30 in the European Heart Journal to coincide with presentation at the European Stroke Congress (ESOC) 2021.
They were developed by an ESOC task force in collaboration with 12 medical societies and with special contribution of the European Association of Preventive Cardiology.
“A chief goal of the task force was to create a single CVD prevention guideline for everyone – for primary care, for hospital care, for guiding clinical practice – so one guideline for all,” said cochair of the guideline committee Frank Visseren, MD, PhD, University Medical Center Utrecht, Netherlands. “We also wanted to make a more personalized CVD prevention guideline, instead of a one-size-fits-all. In clinical practice, people are very, very different, and we really want to have a more individualized prevention guideline,” said Dr. Visseren, as well as provide “more room for shared decision-making.”
Prevention at the individual and population levels
The new guidelines also give more attention to CVD prevention in older persons. “Many of our patients are over 70 years old and we really want to have more detail, more guidance on older persons,” said Dr. Visseren.
The guideline is divided into two sections. One section covers CVD prevention at the individual level in apparently healthy people, in patients with established CVD, and in those with diabetes, familial hypercholesterolemia, or chronic kidney disease.
The other section covers CVD prevention at the population level, including public health policy, interventions, and the environment, including putting in place measures to reduce air pollution, use of fossil fuels, and limiting carbon dioxide emissions.
Targets for blood lipids, blood pressure, and glycemic control in diabetes remain in line with recent ESC guidelines on dyslipidemias, hypertension, or diabetes.
However, the guidelines introduce a new stepwise treatment-intensification approach to achieve these targets, with consideration of CVD risk, treatment benefit of risk factors, risk modifiers, comorbidities, and patient preferences.
The 2021 CVD prevention guidelines also embrace the recently published Systemic Coronary Risk Estimation 2 (SCORE2) and Systemic Coronary Risk Estimation 2-Older Persons (SCORE2-OP) algorithms. “The algorithms we are using are a bit old and we want to have more updated risk prediction, because that’s the starting point of CVD prevention,” Dr. Visseren said.
The guidelines also introduce age-specific risk thresholds for risk factor treatments in apparently healthy people and provide estimation of lifetime CVD risk and treatment benefit. This will allow clinicians to have “an informed discussion with patients on lifetime risk and potential treatment benefits,” Dr. Visseren said.
For the first time, the guidelines recommend smoking cessation regardless of whether it leads to weight gain, as weight gain does not lessen the benefits of cessation.
Regarding exercise, adults of all ages should aim for at least 150-300 minutes a week of moderate, or 75-150 minutes a week of vigorous, aerobic physical activity. The guidelines recommend reducing sedentary time and engaging in at least light activity throughout the day.
Regarding nutrition, the guidelines advise adopting a Mediterranean or similar diet; restricting alcohol intake to a maximum of 100 g per week (a standard drink is 8-14 g); eating fish, preferably fatty fish, at least once a week; and restricting consumption of meat, particularly processed meat.
Also for the first time, the guidelines state that bariatric surgery should be considered for obese individuals at elevated risk of CVD when a healthy diet and exercise fail to lead to weight loss that is maintained.
They note that individuals with mental disorders need additional attention and support to improve adherence to lifestyle changes and drug treatment.
They advise consideration of referring patients with heart disease and significant stress and anxiety to psychotherapeutic stress management to reduce stress symptoms and improve CV outcomes.
Potential cost issues that could be considered when implementing the guidelines are also reviewed.
Dr. Visseren acknowledged and thanked the task force members for continuing their work on the guidelines over the 2 “challenging” years.
Setting the bar lower?
Discussant for the guideline presentation, Diederick Grobbee, MD, University Medical Center Utrecht, who was not involved in drafting the guidelines, said he does have one conflict of interest, which is a “passion for prevention.” From that perspective, he said the guideline panel “should be applauded; the once-every-5-year issuing of the prevention guidelines is a major event.”
Dr. Grobbee noted that the working group “really tried to follow their ambitions and goals, in a way making the guidelines simpler, or perhaps setting the bar not initially as high as we used to do, which may, in fact, sometimes scare off physicians and patients alike.”
“We’ve had prevention guidelines for quite some time now, yet looking at what is accomplished in practice is sobering,” said Dr. Grobbee. Introducing a stepwise approach is “really appealing,” he added.

Exercising to lose weight is not for every ‘body’
Exercising to lose weight is not for every ‘body’
This first item comes from the “You’ve got to be kidding” section of LOTME’s supersecret topics-of-interest file.
Investigators at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences and the University of Roehampton noticed that some people who enrolled in exercise programs to lose weight did just the opposite: they gained weight.
Being scientists, they decided to look at the effects of energy expenditure and how those effects varied among individuals. The likely culprit in this case, they determined, is something called compensatory mechanisms. One such mechanism involves eating more food because exercise stimulates appetite, and another might reduce energy expenditure on other components like resting metabolism so that the exercise is, in effect, less costly.
A look at the numbers shows how compensatory mechanisms worked in the study population of 1,750 adults. Among individuals with the highest BMI, 51% of the calories burned during activity translated into calories burned at the end of the day. For those with normal BMI, however, 72% of calories burned during activity were reflected in total expenditure.
“People living with obesity cut back their resting metabolism when they are more active. The result is that for every calorie they spend on exercise they save about half a calorie on resting,” the investigators explained.
In other words, some bodies will, unconsciously, work against the conscious effort of exercising to lose weight. Thank you very much, compensatory mechanisms, for the boundarylessness exhibited in exceeding your job description.
When it comes to the mix, walnuts go nuts
When it comes to mixed nuts, walnuts get no love. But we may be able to give you a reason to not pick them out: Your arteries.
Participants in a recent study who ate about a half-cup of walnuts every day for 2 years saw a drop in their low-density lipoprotein (LDL) cholesterol. The number and quality of LDL particles in healthy older adults also improved. How? Good ol’ omega-3 fatty acids.
Omega-3 is found in many foods linked to lower risks of heart disease, lower cholesterol levels, and lower blood sugar levels, but the one thing that makes the walnut a front runner for Miss Super Food 2021 is their ability to improve the quality of LDL particles.
“LDL particles come in various sizes [and] research has shown that small, dense LDL particles are more often associated with atherosclerosis, the plaque or fatty deposits that build up in the arteries,” Emilio Ros, MD, PhD, of the Hospital Clínic of Barcelona and the study’s senior investigator, said in a written statement.
The 708 participants, aged 63-79 years and mostly women, were divided into two groups: One received the walnut diet and the other did not. After 2 years, the walnut group had lower LDL levels by an average of 4.3 mg/dL. Total cholesterol was reduced by an average of 8.5 mg/dL. Also, their total LDL particle count was 4.3% lower and small LDL particles were down by 6.1%.
So instead of picking the walnuts out of the mix, try to find it in your heart to appreciate them. Your body already does.
Begun, the clone war has
Well, not quite yet, Master Yoda, but perhaps one day soon, if a study from Japan into the uncanny valley of the usage of cloned humanlike faces in robotics and artificial intelligence, published in PLOS One, is to be believed.
The study consisted of a number of six smaller experiments in which participants judged a series of images based on subjective eeriness, emotional valence, and realism. The images included people with the same cloned face; people with different faces; dogs; identical twins, triplets, quadruplets, etc.; and cloned animated characters. In the sixth experiment, the photos were the same as in the second (six cloned faces, six different faces, and a single face) but participants also answered the Disgust Scale–Revised to accurately analyze disgust sensitivity.
The results of all these experiments were quite clear: People found the cloned faces far creepier than the varied or single face, an effect the researchers called clone devaluation. Notably, this effect only applied to realistic human faces; most people didn’t find the cloned dogs or cloned animated characters creepy. However, those who did were more likely to find the human clones eerie on the Disgust Scale.
The authors noted that future robotics technology needs to be carefully considered to avoid the uncanny valley and this clone devaluation effect, which is a very good point. The last thing we need is a few million robots with identical faces getting angry at us and pulling a Terminator/Order 66 combo. We’re already in a viral apocalypse; we don’t need a robot one on top of that.
Congratulations to our new favorite reader
The winner of last week’s inaugural Pandemic Pandemonium comes to us from Tiffanie Roe. By getting her entry in first, just ahead of the flood of responses we received – and by flood we mean a very slow and very quickly repaired drip – Ms. Roe puts the gold medal for COVID-related insanity around the necks of Australian magpies, who may start attacking people wearing face masks during “swooping season” because the birds don’t recognize them.

The 708 participants, aged 63-79 years and mostly women, were divided into two groups: One received the walnut diet and the other did not. After 2 years, the walnut group had lower LDL levels by an average of 4.3 mg/dL. Total cholesterol was reduced by an average of 8.5 mg/dL. Also, their total LDL particle count was 4.3% lower and small LDL particles were down by 6.1%.
So instead of picking the walnuts out of the mix, try to find it in your heart to appreciate them. Your body already does.
Begun, the clone war has
Well, not quite yet, Master Yoda, but perhaps one day soon, if a study from Japan into the uncanny valley of the usage of cloned humanlike faces in robotics and artificial intelligence, published in PLOS One, is to be believed.
The study consisted of a number of six smaller experiments in which participants judged a series of images based on subjective eeriness, emotional valence, and realism. The images included people with the same cloned face; people with different faces; dogs; identical twins, triplets, quadruplets, etc.; and cloned animated characters. In the sixth experiment, the photos were the same as in the second (six cloned faces, six different faces, and a single face) but participants also answered the Disgust Scale–Revised to accurately analyze disgust sensitivity.
The results of all these experiments were quite clear: People found the cloned faces far creepier than the varied or single face, an effect the researchers called clone devaluation. Notably, this effect only applied to realistic human faces; most people didn’t find the cloned dogs or cloned animated characters creepy. However, those who did were more likely to find the human clones eerie on the Disgust Scale.
The authors noted that future robotics technology needs to be carefully considered to avoid the uncanny valley and this clone devaluation effect, which is a very good point. The last thing we need is a few million robots with identical faces getting angry at us and pulling a Terminator/Order 66 combo. We’re already in a viral apocalypse; we don’t need a robot one on top of that.

The winner of last week’s inaugural Pandemic Pandemonium comes to us from Tiffanie Roe. By getting her entry in first, just ahead of the flood of responses we received – and by flood we mean a very slow and very quickly repaired drip – Ms. Roe puts the gold medal for COVID-related insanity around the necks of Australian magpies, who may start attacking people wearing face masks during “swooping season” because the birds don’t recognize them.
Exercising to lose weight is not for every ‘body’
This first item comes from the “You’ve got to be kidding” section of LOTME’s supersecret topics-of-interest file.
Investigators at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences and the University of Roehampton noticed that some people who enrolled in exercise programs to lose weight did just the opposite: they gained weight.
Being scientists, they decided to look at the effects of energy expenditure and how those effects varied among individuals. The likely culprit in this case, they determined, is something called compensatory mechanisms. One such mechanism involves eating more food because exercise stimulates appetite, and another might reduce energy expenditure on other components like resting metabolism so that the exercise is, in effect, less costly.
A look at the numbers shows how compensatory mechanisms worked in the study population of 1,750 adults. Among individuals with the highest BMI, 51% of the calories burned during activity translated into calories burned at the end of the day. For those with normal BMI, however, 72% of calories burned during activity were reflected in total expenditure.
“People living with obesity cut back their resting metabolism when they are more active. The result is that for every calorie they spend on exercise they save about half a calorie on resting,” the investigators explained.
In other words, some bodies will, unconsciously, work against the conscious effort of exercising to lose weight. Thank you very much, compensatory mechanisms, for the boundarylessness exhibited in exceeding your job description.
When it comes to the mix, walnuts go nuts
When it comes to mixed nuts, walnuts get no love. But we may be able to give you a reason to not pick them out: Your arteries.
Participants in a recent study who ate about a half-cup of walnuts every day for 2 years saw a drop in their low-density lipoprotein (LDL) cholesterol. The number and quality of LDL particles in healthy older adults also improved. How? Good ol’ omega-3 fatty acids.
Omega-3 is found in many foods linked to lower risks of heart disease, lower cholesterol levels, and lower blood sugar levels, but the one thing that makes the walnut a front runner for Miss Super Food 2021 is their ability to improve the quality of LDL particles.

Bystander rescue breathing CPR in kids tied to better survival
Children who receive CPR with both rescue breathing and compressions from a bystander have greater odds of survival without serious brain damage than if they receive CPR with compressions only, according to a study published online in the Journal of the American College of Cardiology.
Specifically, a child has a 61% better chance of surviving with good neurologic outcomes if they receive compression-only CPR versus no bystander resuscitation, but that child is more than twice as likely to survive if he or she receives rescue breathing as well.
The study’s clinical implications are most important for bystander CPR training, lead author Maryam Y. Naim, MD, MSCE, of the Children’s Hospital of Philadelphia and the University of Pennsylvania, also in Philadelphia, told this news organization.
“Many programs teach compression-only CPR to lay rescuers, and there should be a renewed emphasis on rescue breathing for the possibility a lay rescuer has to perform CPR on a child,” Dr. Naim said.
That said, if a bystander is unfamiliar with how to properly administer rescue breathing or has concerns about hygiene or infection on someone they don’t know, Dr. Naim advises doing compression-only CPR, especially if the child is older than age 1 year. “If a child is younger than a year of age please consider giving rescue breaths with chest compressions,” she added.
Dr. Naim and colleagues analyzed 13,060 pediatric out-of-hospital cardiac arrests from the Cardiac Arrest Registry to Enhance Survival database, which includes data from 911 call centers, emergency medical services (EMS) providers, and receiving hospitals across 28 states. The data sample included all cases age 18 years or younger who experienced nontraumatic out-of-hospital cardiac arrest between January 2013 and December 2019, excluding those with obvious signs of death or a “do not resuscitate” order.
“Because the etiology of cardiac arrest in children is difficult to determine, especially in cases that result in death, all nontraumatic cases were included regardless of presumed etiology, including respiratory, cardiac, drowning, electrocution, or other,” the authors wrote. The researchers defined neurologically favorable survival, the primary endpoint, as “a cerebral performance category score of 1 (no neurologic disability) or 2 (moderate disability)” at discharge. Neurologically unfavorable survival included a score of 3 (severe disability), 4 (coma or vegetative state), or death.
Among the 10,429 cases ultimately analyzed after exclusions and missing data, 46.5% received bystander CPR. Slightly more than half of these (55.6%) received compression-only CPR while the other 45.3% received rescue-breathing CPR.
Dr. Naim was surprised that compression-only CPR was the most common form of CPR given to children with cardiac arrest because the current American Heart Association/International Liaison Committee on Resuscitation recommendations note rescue breathing as the preferred form in children.
That preference exists because respiratory failure occurs more often in children than in adults as a cause of cardiac arrest, explained Sandra Weiss, MD, an interventional cardiologist and the medical director of the cardiac intensive care unit at ChristianaCare’s Christiana Hospital in Newark, Del.
Because of that, “it’s not surprising that if you give respiratory resuscitation to a child who’s arresting from a respiratory cause that they’re going to do better than if you just do chest compressions,” said Dr. Weiss, who was not involved in the study.
The study found the most common presumed cause of arrest to be cardiac, occurring in 44.4% of cases, but it was closely followed by respiratory in nearly one-third of cases (32.8%).
Infants younger than age 1 year were the most common age group to have a cardiac arrest, making up more than all other ages combined. Most out-of-hospital cardiac arrests occurred in a home and were observed by someone when they happened. While rates of bystander CPR did not change during the study’s 6-year period, the incidence of compression-only CPR increased. Lay people without medical training provided the CPR in 93.6% of cases.
Only 8.6% of cardiac arrest cases resulted in neurologically favorable survival, a rate which remained steady throughout the study period. The rate increased with increasing age, at 4.6% of infants, 10.6% of children, and 16.5% of adolescents.
Those who received CPR with rescue breathing had more than double the odds of neurologically favorable survival than if they hadn’t received CPR at all (adjusted odds ratio, 2.16). Survival with a positive neurologic outcome was 1.6 times more likely with compression-only CPR than no CPR (aOR, 1.61). When researchers compared the two forms of CPR, inclusion of rescue breathing increased the child’s likelihood of survival without neurologic sequelae by 36% (aOR, 1.36).
Despite these findings, however, Dr. Weiss agrees with Dr. Naim that offering compression-only CPR is preferable to offering no CPR at all.
“All resuscitation is better than no resuscitation, regardless of whether it’s compression only or respiratory breathing,” Dr. Weiss said in an interview. “The average lay person is probably going to do the easiest thing, and survivability is going to be increased by doing anything rather than nothing.”
Dr. Weiss also noted that it’s easier to instruct people how to do chest compressions, especially, for example, during an emergency phone call with a dispatcher while waiting for EMS to arrive.
“It’s absolutely imperative for people to get the basics, and the basics are compressions,” she said. “That’s really what is the most vital component of all resuscitative efforts, regardless of whether it’s adult or pediatrics.”
Dr. Weiss also acknowledges that laypeople may feel particularly less comfortable administering rescue breaths to a child they don’t know in the midst of the COVID-19 pandemic. Even if the odds are low that the specific child experiencing a cardiac arrest is necessarily infectious, the AHA guidelines include the caveat that, “if there’s a concern for infection transmissibility, that compression only is acceptable,” Dr. Weiss said. “It’s a reality for our current state.”
The superiority of rescue-breathing CPR to compression-only CPR was true across all age groups, but compression-only CPR still resulted in better survival odds than no CPR at all for all age groups except infants, in whom only rescue breathing was associated with a statistically significant increased likelihood of neurologically favorable survival.
Protective factors for positive outcomes included being younger than age 1 year, the arrest being witnessed, and a having shockable rhythm. Risk factors reducing survival included being Black, being in a home, and cardiac arrests linked with automated external defibrillator use before EMS arrived.
The CARES program was previously funded by the Centers for Disease Control and Prevention and is now funded by the American Red Cross, the AHA, Stryker, and Emory University. Dr. Naim was further supported by Children’s Hospital of Philadelphia and the American Red Cross. The authors and Dr. Weiss disclosed no relevant financial relationships.

Two swings, two misses with colchicine, Vascepa in COVID-19
The anti-inflammatory agents colchicine and icosapent ethyl (Vascepa; Amarin) failed to provide substantial benefits in separate randomized COVID-19 trials.
Both were reported at the European Society of Cardiology (ESC) Congress 2021.
The open-label ECLA PHRI COLCOVID trial randomized 1,277 hospitalized adults (mean age 62 years) to usual care alone or with colchicine at a loading dose of 1.5 mg for 2 hours followed by 0.5 mg on day 1 and then 0.5 mg twice daily for 14 days or until discharge.
The investigators hypothesized that colchicine, which is widely used to treat gout and other inflammatory conditions, might modulate the hyperinflammatory syndrome, or cytokine storm, associated with COVID-19.
Results showed that the need for mechanical ventilation or death occurred in 25.0% of patients receiving colchicine and 28.8% with usual care (P = .08).
The coprimary endpoint of death at 28 days was also not significantly different between groups (20.5% vs. 22.2%), principal investigator Rafael Diaz, MD, said in a late-breaking COVID-19 trials session at the congress.
Among the secondary outcomes at 28 days, colchicine significantly reduced the incidence of new intubation or death from respiratory failure from 27.0% to 22.3% (hazard ratio, 0.79; 95% confidence interval, 0.63-0.99) but not mortality from respiratory failure (19.5% vs. 16.8%).
The only important adverse effect was severe diarrhea, which was reported in 11.3% of the colchicine group vs. 4.5% in the control group, said Dr. Diaz, director of Estudios Clínicos Latinoamérica (ECLA), Rosario, Argentina.
The results are consistent with those from the massive RECOVERY trial, which earlier this year stopped enrollment in the colchicine arm for lack of efficacy in patients hospitalized with COVID-19, and COLCORONA, which missed its primary endpoint using colchicine among nonhospitalized adults with COVID-19.
Session chair and COLCORONA principal investigator Jean-Claude Tardif, MD, pointed out that, as clinicians, it’s fairly uncommon to combine systemic steroids with colchicine, which was the case in 92% of patients in ECLA PHRI COLCOVID.
“I think it is an inherent limitation of testing colchicine on top of steroids,” said Dr. Tardif, of the Montreal Heart Institute.
Icosapent ethyl in PREPARE-IT
Dr. Diaz returned in the ESC session to present the results of the PREPARE-IT trial, which tested whether icosapent ethyl – at a loading dose of 8 grams (4 capsules) for the first 3 days and 4 g/d on days 4-60 – could reduce the risk for SARS-CoV-2 infection in 2,041 health care and other public workers in Argentina at high risk for infection (mean age 40.5 years).
Vascepa was approved by the Food and Drug Administration in 2012 for the reduction of elevated triglyceride levels, with an added indication in 2019 to reduce cardiovascular (CV) events in people with elevated triglycerides and established CV disease or diabetes with other CV risk factors.
The rationale for using the high-dose prescription eicosapentaenoic acid (EPA) preparation includes its anti-inflammatory and antithrombotic effects, and that unsaturated fatty acids, especially EPA, might inactivate the enveloped virus, he explained.
Among 1,712 participants followed for up to 60 days, however, the SARS-CoV-2 infection rate was 7.9% with icosapent ethyl vs. 7.1% with a mineral oil placebo (P = .58).
There were also no significant changes from baseline in the icosapent ethyl and placebo groups for the secondary outcomes of high-sensitivity C-reactive protein (0 vs. 0), triglycerides (median –2 mg/dL vs. 7 mg/dL), or Influenza Patient-Reported Outcome (FLU-PRO) questionnaire scores (median 0.01 vs. 0.03).
The use of a mineral oil placebo has been the subject of controversy in previous fish oil trials, but, Dr. Diaz noted, it did not have a significant proinflammatory effect or cause any excess adverse events.
Overall, adverse events were similar between the active and placebo groups, including atrial fibrillation (none), major bleeding (none), minor bleeding (7 events vs. 10 events), gastrointestinal symptoms (6.8% vs. 7.0%), and diarrhea (8.6% vs. 7.7%).
Although it missed the primary endpoint, Dr. Diaz said, “this is the first large, randomized blinded trial to demonstrate excellent safety and tolerability of an 8-gram-per-day loading dose of icosapent ethyl, opening up the potential for acute use in randomized trials of myocardial infarction, acute coronary syndromes, strokes, and revascularization.”
During a discussion of the results, Dr. Diaz said the Delta variant was not present at the time of the analysis and that the second half of the trial will report on whether icosapent ethyl can reduce the risk for hospitalization or death in participants diagnosed with COVID-19.
ECLA PHRI COLCOVID was supported by the Estudios Clínicos Latinoamérica Population Health Research Institute. PREPARE-IT was supported by Estudios Clínicos Latinoamérica with collaboration from Amarin. Dr. Diaz reports no relevant financial relationships.

The coprimary endpoint of death at 28 days was also not significantly different between groups (20.5% vs. 22.2%), principal investigator Rafael Diaz, MD, said in a late-breaking COVID-19 trials session at the congress.
Among the secondary outcomes at 28 days, colchicine significantly reduced the incidence of new intubation or death from respiratory failure from 27.0% to 22.3% (hazard ratio, 0.79; 95% confidence interval, 0.63-0.99) but not mortality from respiratory failure (19.5% vs. 16.8%).
The only important adverse effect was severe diarrhea, which was reported in 11.3% of the colchicine group vs. 4.5% in the control group, said Dr. Diaz, director of Estudios Clínicos Latinoamérica (ECLA), Rosario, Argentina.
The results are consistent with those from the massive RECOVERY trial, which earlier this year stopped enrollment in the colchicine arm for lack of efficacy in patients hospitalized with COVID-19, and COLCORONA, which missed its primary endpoint using colchicine among nonhospitalized adults with COVID-19.
Session chair and COLCORONA principal investigator Jean-Claude Tardif, MD, pointed out that, as clinicians, it’s fairly uncommon to combine systemic steroids with colchicine, which was the case in 92% of patients in ECLA PHRI COLCOVID.
“I think it is an inherent limitation of testing colchicine on top of steroids,” said Dr. Tardif, of the Montreal Heart Institute.
Icosapent ethyl in PREPARE-IT
Dr. Diaz returned in the ESC session to present the results of the PREPARE-IT trial, which tested whether icosapent ethyl – at a loading dose of 8 grams (4 capsules) for the first 3 days and 4 g/d on days 4-60 – could reduce the risk for SARS-CoV-2 infection in 2,041 health care and other public workers in Argentina at high risk for infection (mean age 40.5 years).
Vascepa was approved by the Food and Drug Administration in 2012 for the reduction of elevated triglyceride levels, with an added indication in 2019 to reduce cardiovascular (CV) events in people with elevated triglycerides and established CV disease or diabetes with other CV risk factors.
The rationale for using the high-dose prescription eicosapentaenoic acid (EPA) preparation includes its anti-inflammatory and antithrombotic effects, and that unsaturated fatty acids, especially EPA, might inactivate the enveloped virus, he explained.
Among 1,712 participants followed for up to 60 days, however, the SARS-CoV-2 infection rate was 7.9% with icosapent ethyl vs. 7.1% with a mineral oil placebo (P = .58).
There were also no significant changes from baseline in the icosapent ethyl and placebo groups for the secondary outcomes of high-sensitivity C-reactive protein (0 vs. 0), triglycerides (median –2 mg/dL vs. 7 mg/dL), or Influenza Patient-Reported Outcome (FLU-PRO) questionnaire scores (median 0.01 vs. 0.03).
The use of a mineral oil placebo has been the subject of controversy in previous fish oil trials, but, Dr. Diaz noted, it did not have a significant proinflammatory effect or cause any excess adverse events.
Overall, adverse events were similar between the active and placebo groups, including atrial fibrillation (none), major bleeding (none), minor bleeding (7 events vs. 10 events), gastrointestinal symptoms (6.8% vs. 7.0%), and diarrhea (8.6% vs. 7.7%).
Although it missed the primary endpoint, Dr. Diaz said, “this is the first large, randomized blinded trial to demonstrate excellent safety and tolerability of an 8-gram-per-day loading dose of icosapent ethyl, opening up the potential for acute use in randomized trials of myocardial infarction, acute coronary syndromes, strokes, and revascularization.”
During a discussion of the results, Dr. Diaz said the Delta variant was not present at the time of the analysis and that the second half of the trial will report on whether icosapent ethyl can reduce the risk for hospitalization or death in participants diagnosed with COVID-19.

The anti-inflammatory agents colchicine and icosapent ethyl (Vascepa; Amarin) failed to provide substantial benefits in separate randomized COVID-19 trials.
Both were reported at the European Society of Cardiology (ESC) Congress 2021.
The open-label ECLA PHRI COLCOVID trial randomized 1,277 hospitalized adults (mean age 62 years) to usual care alone or with colchicine at a loading dose of 1.5 mg for 2 hours followed by 0.5 mg on day 1 and then 0.5 mg twice daily for 14 days or until discharge.
