Escaping the daily grind
Few films have universal appeal these days, but one that comes close is the 1993 classic Groundhog Day, in which the protagonist is trapped in a time loop, doomed to living the same day over and over for many years.
One reason that this story resonates with so many, I think, is that we are all living a similar life. Not as a same-day loop, of course; but each week seems eerily similar to the last, as does each month, each year – on and on, ad infinitum. That’s why it is so important, every so often, to step out of the “loop” and reassess the bigger picture.
I write this reminder every couple of years because it’s so easy to lose sight of the overall landscape among the pressures of our daily routines. . And we are too busy to sit down and think about what we might do to break that vicious cycle. This is detrimental to our own well being, as well as that of our patients.
There are many ways to maintain your intellectual and emotional health, but here’s how I do it: I take individual days off (average of one a month) to catch up on journals or taking a CME course; or to try something new – something I’ve been thinking about doing “someday, when there is time” – such as a guitar, bass, or sailing lessons; or a long weekend away with my wife.
And until COVID-19 put a temporary stop to them earlier this year, we have embarked on at least one longer adventure each year, some of which have been shared in these pages. Our 2019 expedition to Easter Island remains among the most memorable, and fulfilled a dream I’ve had since I read Thor Heyerdahl’s Aku Aku in grade school. As we explored the giant stone moai – which are found nowhere else in the world – I didn’t have the time – or the slightest inclination – to worry about the office. But I did accumulate some great ideas – practical, medical, and literary. Original thoughts are hard to chase down during the daily grind; but in a refreshing environment, they will seek you out. When our trip was over, I returned ready to take on the world, and my practice, anew.
I know how some of you feel about “wasting” a day – or, God forbid, a week. Patients might go elsewhere while you’re gone, and every day the office is idle you “lose money.” That whole paradigm is wrong. You bring in a given amount of revenue per year – more on some days, less on other days, none on weekends and vacations; it all averages out in the end.
Besides, this is much more important than money; this is breaking the routine, clearing the cobwebs, living your life. Trust me, your practice will still be there when you return. And while COVID-19 will not last forever, there are plenty of other “sharpeners” while we wait.
More than once I’ve recounted the story of Alex Müller and J. Georg Bednorz, the Swiss Nobel Laureates whose superconductivity research ground to a halt in 1986. The harder they pressed, the more elusive progress became. So Müller decided to take a break to read a new book on ceramics – a subject that had always interested him.
Nothing could have been less relevant to his work, of course; ceramics are among the poorest conductors known. But in that lower-pressure environment, Müller realized that a unique property of ceramics might apply to their project.
Back in the lab, the team created a ceramic compound that became the first successful “high-temperature” superconductor, which in turn triggered an explosion of research leading to breakthroughs in computing, electricity transmission, magnetically-elevated trains, and many applications yet to be realized.
Sharpening your saw may not change the world, but it will change you; any nudge out of your comfort zone will give you fresh ideas and help you look at seemingly insoluble problems in completely new ways.
And to those who still can’t bear the thought of taking time off, remember the dying words that no one has spoken, ever: “I wish I had spent more time in my office!”

Liquid biopsy captures key NASH pathology hallmarks
Large-scale scanning of serum proteins offers a potential method for noninvasive screening and monitoring of patients with nonalcoholic steatohepatitis (NASH), the technique’s developers claim.
By scanning for about 5,000 proteins in nearly 3,000 samples from patients enrolled in studies from the Clinical Research Network in NASH (NASH CRN), Rachel Ostroff, PhD, and colleagues from SomaLogic in Boulder, Colo., created four protein models that mimic results of the major pathologic findings in liver tissue biopsy.
“Concurrent positive results from the protein models had performance characteristics of ‘rule-out’ tests for pathologists’ diagnosis of NASH. These tests may assist in new drug development and medical intervention decisions,” they wrote in a late-breaking poster presented at the virtual annual meeting of the American Association for the Study of Liver Diseases.
“There is no single noninvasive method that can accurately and simultaneously capture steatosis, inflammation, hepatocyte ballooning and fibrosis, the four major pathologic components assessed by biopsy. Each of these is relevant to the multiple mechanisms targeted in drug development for NASH,” they wrote.
To see whether large-scale protemoics could serve as an alternative to invasive liver biopsy for use in clinical trials or in longitudinal studies of NASH, they used a modified aptamer proteomics platform to scan for liver-related proteins. Aptamers are olignonucleotide or peptide molecules designed to home in on a specific target.
They scanned for approximately 5,000 proteins in 2,852 serum samples from 638 patients in a NASH CRN natural history cohort, and in patients enrolled in two NASH treatment trials: the PIVENS trial, which is evaluating pioglitazone versus vitamin E and placebo in nondiabetic patients, and the FLINT trial, which is comparing obeticholic acid with placebo. All of the patients in the natural history cohort and half of all patients in the clinical trial cohorts were included in the training sets, with the remaining half included in the validation set.
The accuracy of the models, as measured by the area under the curve (AUC) of receiver operating characteristics in the training and validation sets, respectively, were as follows:
- Fibrosis: AUC 0.92/0.85.
- Steatosis: AUC 0.95/0.79.
- Inflammation: AUC 0.83/0.72.
- Hepatocyte Ballooning: AUC 0.87/0.83.
“A concurrent positive score for steatosis, inflammation and ballooning predicted the biopsy diagnosis of NASH with an accuracy of 73%,” Ostroff and colleagues wrote.
They also found that model scores applied over time showed improvements in symptoms in the patients on active therapies in the clinical trials, compared with patients on placebo.
A specialist in liver pathology and nonalcoholic fatty liver disease who was not involved in the study said in an interview that she finds the results highly promising.
Impressive results
Elizabeth M. Brunt, MD, emeritus professor of pathology and immunology at Washington University in St. Louis, was a member of the NASH CRN when SomaLogic first proposed using the groups’ data for this study.
“I was impressed with them then, and I am very impressed with what they’re presenting here, and I can’t say that about all the noninvasive tests,” she said. “I think a lot of noninvasive tests are way over-simplifying what NASH is.”
She acknowledged that, although she spent much of her career performing liver biopsies, “you can’t biopsy every single patients who you suspect of having NASH, or certainly if you want to follow them over time – it’s unrealistic,” she said in an interview.
Although the protein scanning method cannot – and is not intended to – replace a well-conducted biopsy with the interpretation of a skilled pathologist, the proteins the company investigators identified can reflect the dynamic nature of liver disease and the liver’s ability to heal itself with a high degree of accuracy and hold promise for both screening patients and for monitoring responses to therapy, Dr. Brunt said.
The study was sponsored by SomaLogic. The authors are employees of the company. Dr. Brunt had no relevant disclosures.

In those with obesity, will losing weight cut COVID-19 severity?
As study after study piles up showing that those with obesity who become infected with SARS-CoV-2 are more likely to have severe disease, several experts gave advice for clinicians and patients during the virtual ObesityWeek Interactive 2020 meeting.
Pichamol Jirapinyo, MD, MPH, associate director of bariatric endoscopy at Brigham and Women’s Hospital, Boston, presented a study on those with obesity from New England hospitals which adds to the evidence that this is “a vulnerable population for COVID-19, like elderly or immunocompromised people,” Dr. Jirapinyo said in an interview.
These findings reinforce the need for clinicians to be “more aware of complications of obesity and refer earlier for treatment,” she added.
One audience member wanted to know if there are data showing whether people with a body mass index (BMI) above 35 kg/m2 who successfully lose weight subsequently have lower rates of hospitalization, ICU admission, and death if they become infected with SARS-CoV-2.
Dr. Jirapinyo said she is not aware of any such studies, but anecdotally, two of her patients who had endoscopic sleeve gastroplasty last fall (whose BMI dropped from about 38 to 30) and later became infected with COVID-19 had mild symptoms.
But David A. Kass, MD, director, Institute of CardioScience at Johns Hopkins University, Baltimore, cautioned that
“Whether this gets reversed by weight loss is an attractive hypothesis, but at this point, it’s still a hypothesis,” he stressed.
Changes to immunity, inflammatory signaling in obesity
“There must be north of 600 or more studies by now with this message that obesity – particularly severe obesity with a BMI of 35 and higher – is a strong independent risk factor for worse COVID-19 outcome,” Dr. Kass emphasized.
“[COVID-19] revealed to the public in a somewhat dramatic fashion that being very obese does put one at higher risk of this disease being more debilitating and even fatal,” he added.
“Before this pandemic, many viewed obesity as only a problem if you have the other associated diseases – hypertension, diabetes, heart disease, atherosclerosis, obstructive sleep apnea, etc.”
“What was not as appreciated is that marked obesity changes the body in various ways all by itself – altering metabolism, inflammatory signaling, immune surveillance, and responsiveness (including a less robust response to vaccines that has been written about as well).”
“This is a bit like having a genetic abnormality that makes you at higher risk for getting, say, cancer,” he explained.
“It is there, it is real, it has an impact – but it still does take other stresses to reveal the risk potential. COVID-19 did that with obesity,” he said.
Latest study on effect of obesity, diabetes on COVID-19 severity
The study presented by Dr. Jirapinyo and colleagues identified 1,680 patients with COVID-19 at six hospitals in March 2020. Patients were a mean age of 51 years, had a mean BMI of 29.4, and 39% had obesity. Patients who required hospitalization were more likely to have obesity (46% vs. 35%; P < .0001).
Obesity was a significant risk factor for hospitalization (odds ratio, 1.7), ICU admission (OR, 1.8), and intubation (OR, 1.8; all P < .001), after controlling for age, sex, cardiovascular, pulmonary, liver, and kidney disease, and cancer.
Compared with having a normal weight, having severe obesity was also associated with roughly threefold higher risks of ICU admission and intubation – after controlling for major comorbidities.
Pandemic focuses minds on obesity prevention, treatment
Naveed Sattar, MD, PhD, said in an interview that these latest findings are “highly consistent with other studies that point to excess adiposity as a potential modifiable risk factor for more severe COVID-19.”
It “also strongly suggests that if people are worried about their risk for COVID-19 and want to improve their chances of a milder outcome, then it is reasonable to encourage them to make sustainable lifestyle changes that may lessen weight and improve their fitness levels,” said Dr. Sattar, professor of metabolic medicine, University of Glasgow.
“But of course, the big worry,” he added, “is that many are putting on weight due to lockdowns, less commuting to work, anxiety, and overeating and drinking, etc., so that many are struggling, and especially those at highest risk, such as those living in more overcrowded housing, etc. By contrast, more advantaged folk may have an easier time to improve lifestyles.”
The pandemic highlights that “we need a concerted effort on obesity prevention and treatment,” according to Dr. Sattar.
“For years we have realized links between obesity and chronic cardiometabolic conditions,” he said, “but to think excess weight may also be detrimental to acute effects of a novel virus running amok in the world has focused minds on obesity in a manner not seen before.
“Whether these new painful learnings lead to a more determined effort in countries to improve the obesogenic environment or to place more resources into prevention and management of obesity remains to be seen,” he said.
Increased inquiries about bariatric surgery following COVID-19
Meanwhile, Matthew M. Hutter, MD, MPH, president, American Society for Metabolic and Bariatric Surgery, said in an interview that “COVID-19 and studies like this are now making many aware that obesity is not just a lifestyle choice or a cosmetic issue, but “a disease that needs to be taken seriously” and treated.
“Metabolic and bariatric surgery is a very safe and effective treatment for persons with obesity with a BMI >40 kg/m2 or BMI >35 kg/m2 and related diseases like diabetes, hypertension, sleep apnea, reflux, back pain, and many others,” added Dr. Hutter, who is also professor of surgery, Harvard Medical School, Boston.
“Recently, some metabolic and bariatric centers have seen an increase in patients considering surgery,” he said. “Some say that COVID-19 has made them realize they need to do something to be healthier.”
“Currently, less than 1% of those who could benefit from surgery are actually having” it each year, Dr. Hutter noted, “and I think there are many who should seriously consider surgery to be healthier, live longer, and live better.”

Naveed Sattar, MD, PhD, said in an interview that these latest findings are “highly consistent with other studies that point to excess adiposity as a potential modifiable risk factor for more severe COVID-19.”
It “also strongly suggests that if people are worried about their risk for COVID-19 and want to improve their chances of a milder outcome, then it is reasonable to encourage them to make sustainable lifestyle changes that may lessen weight and improve their fitness levels,” said Dr. Sattar, professor of metabolic medicine, University of Glasgow.
“But of course, the big worry,” he added, “is that many are putting on weight due to lockdowns, less commuting to work, anxiety, and overeating and drinking, etc., so that many are struggling, and especially those at highest risk, such as those living in more overcrowded housing, etc. By contrast, more advantaged folk may have an easier time to improve lifestyles.”
The pandemic highlights that “we need a concerted effort on obesity prevention and treatment,” according to Dr. Sattar.
“For years we have realized links between obesity and chronic cardiometabolic conditions,” he said, “but to think excess weight may also be detrimental to acute effects of a novel virus running amok in the world has focused minds on obesity in a manner not seen before.
“Whether these new painful learnings lead to a more determined effort in countries to improve the obesogenic environment or to place more resources into prevention and management of obesity remains to be seen,” he said.
Increased inquiries about bariatric surgery following COVID-19
Meanwhile, Matthew M. Hutter, MD, MPH, president, American Society for Metabolic and Bariatric Surgery, said in an interview that “COVID-19 and studies like this are now making many aware that obesity is not just a lifestyle choice or a cosmetic issue, but “a disease that needs to be taken seriously” and treated.
“Metabolic and bariatric surgery is a very safe and effective treatment for persons with obesity with a BMI >40 kg/m2 or BMI >35 kg/m2 and related diseases like diabetes, hypertension, sleep apnea, reflux, back pain, and many others,” added Dr. Hutter, who is also professor of surgery, Harvard Medical School, Boston.
“Recently, some metabolic and bariatric centers have seen an increase in patients considering surgery,” he said. “Some say that COVID-19 has made them realize they need to do something to be healthier.”
“Currently, less than 1% of those who could benefit from surgery are actually having” it each year, Dr. Hutter noted, “and I think there are many who should seriously consider surgery to be healthier, live longer, and live better.”

As study after study piles up showing that those with obesity who become infected with SARS-CoV-2 are more likely to have severe disease, several experts gave advice for clinicians and patients during the virtual ObesityWeek Interactive 2020 meeting.
Pichamol Jirapinyo, MD, MPH, associate director of bariatric endoscopy at Brigham and Women’s Hospital, Boston, presented a study on those with obesity from New England hospitals which adds to the evidence that this is “a vulnerable population for COVID-19, like elderly or immunocompromised people,” Dr. Jirapinyo said in an interview.
These findings reinforce the need for clinicians to be “more aware of complications of obesity and refer earlier for treatment,” she added.
One audience member wanted to know if there are data showing whether people with a body mass index (BMI) above 35 kg/m2 who successfully lose weight subsequently have lower rates of hospitalization, ICU admission, and death if they become infected with SARS-CoV-2.
Dr. Jirapinyo said she is not aware of any such studies, but anecdotally, two of her patients who had endoscopic sleeve gastroplasty last fall (whose BMI dropped from about 38 to 30) and later became infected with COVID-19 had mild symptoms.
But David A. Kass, MD, director, Institute of CardioScience at Johns Hopkins University, Baltimore, cautioned that
“Whether this gets reversed by weight loss is an attractive hypothesis, but at this point, it’s still a hypothesis,” he stressed.
Changes to immunity, inflammatory signaling in obesity
“There must be north of 600 or more studies by now with this message that obesity – particularly severe obesity with a BMI of 35 and higher – is a strong independent risk factor for worse COVID-19 outcome,” Dr. Kass emphasized.
“[COVID-19] revealed to the public in a somewhat dramatic fashion that being very obese does put one at higher risk of this disease being more debilitating and even fatal,” he added.
“Before this pandemic, many viewed obesity as only a problem if you have the other associated diseases – hypertension, diabetes, heart disease, atherosclerosis, obstructive sleep apnea, etc.”
“What was not as appreciated is that marked obesity changes the body in various ways all by itself – altering metabolism, inflammatory signaling, immune surveillance, and responsiveness (including a less robust response to vaccines that has been written about as well).”
“This is a bit like having a genetic abnormality that makes you at higher risk for getting, say, cancer,” he explained.
“It is there, it is real, it has an impact – but it still does take other stresses to reveal the risk potential. COVID-19 did that with obesity,” he said.
Latest study on effect of obesity, diabetes on COVID-19 severity
The study presented by Dr. Jirapinyo and colleagues identified 1,680 patients with COVID-19 at six hospitals in March 2020. Patients were a mean age of 51 years, had a mean BMI of 29.4, and 39% had obesity. Patients who required hospitalization were more likely to have obesity (46% vs. 35%; P < .0001).
Obesity was a significant risk factor for hospitalization (odds ratio, 1.7), ICU admission (OR, 1.8), and intubation (OR, 1.8; all P < .001), after controlling for age, sex, cardiovascular, pulmonary, liver, and kidney disease, and cancer.
Compared with having a normal weight, having severe obesity was also associated with roughly threefold higher risks of ICU admission and intubation – after controlling for major comorbidities.

SAMSON pins most muscle pain experienced with statins on the nocebo effect
A novel randomized trial taking on a vexing issue around one of the world’s most commonly prescribed medications has concluded that frequently intolerable statin side effects, such as muscle weakness or pain, are almost entirely a nocebo effect, the placebo effect’s darker cousin.
The many patients who report such symptoms while taking statins are indeed probably feeling them, but they are a result of taking the pills rather than any pharmacologic effects, concluded researchers based on their 60-patient study, Self-Assessment Method for Statin Side-effects or Nocebo (SAMSON).
“SAMSON leaves no doubt that patients really do get side effects from statin tablets, but what it shows us is that 90% of this symptomatic burden is elicited by placebo tablets too,” said James P. Howard, MB, PhD, Imperial College London, when presenting the results Nov. 15 at the American Heart Association scientific sessions. They were published simultaneously in the New England Journal of Medicine.
Studies have shown that in practice “more than half of patients abandon statins completely within 2 years. And yet, in placebo-controlled trials, no more people stop statins than placebo,” Dr. Howard said.
“The most important message from SAMSON is that side effects from statin tablets are very real, but they are mainly caused by the act of taking the tablets, not by the statin that is contained within them.”
Patients in the trial, all of whom had a history of dropping statins because of side effects, each took atorvastatin 20 mg/day, a placebo, or neither pill for 1 month, alternating the regimens in randomized order over 1 year so that each was followed a total of 4 months. They used a smartphone app to record the severity of any side effects, not necessarily just pain, on a scale of 0-100.
Symptom intensity scores averaged 16.3 for atorvastatin and 15.4 for placebo, for a nonsignificant difference, but only 8.0 for no-pill months (P < .001 compared with the statin or placebo).
Because such symptoms seem to be based on patient expectations from statin therapy, positive communication about what the drugs can achieve and how the next treatment steps are described can play a big role in their continued use.
For example, “changing them to another statin is a very reasonable thing to do, but as soon as you start trying people on lower doses and working up, you’re sort of telling them that you’re expecting at some dose that they are going to get side effects,” cautioned Dr. Howard at a media briefing on SAMSON.
“The most important thing is to explain the evidence, and what our expectations are, maybe be a bit more optimistic about statins, and tell them they’re very unlikely to suffer from side effects,” he explained, “because the nocebo effect can only really rear its head if the patients are expecting to feel worse – just like the placebo effect will only work if people are expecting to feel better.”
Amit Khera, MD, who moderated the media briefing, said he always tells such patients: “Yes, 1 in 10 patients report having muscle ache. But first and foremost, 9 in 10 don’t. The vast majority of patients don’t get muscle aches. I think that’s really an important part of the communication.”
Now, after SAMSON, “I have an additional point that I’m going to tell them: out of the patients that get muscle aches, probably 90% of that is the anticipation of getting the statin, the nocebo effect,” said Dr. Khera, who directs the preventive cardiology program at the University of Texas Southwestern Medical Center, Dallas.
In practice, however, many patients who report adverse statin effects do so later than 2 weeks after starting therapy, “so these findings cannot be generalized to them,” proposed Francine K. Welty, MD, PhD, Beth Israel Deaconess Medical Center, Boston, as the invited discussant after Dr. Howard’s presentation.
All 60 patients recruited for SAMSON had previously stopped taking a statin because of side effects that arose within 2 weeks of their first dose. That requirement was intended to boost chances that any further symptoms during the trial would arise within a month of starting each new round of pills, Dr. Howard said.
So the trial’s results, Dr. Welty said, “are limited to those subjects who develop symptoms within 2 weeks of starting a statin.”
Including only such patients may have created bias toward a nocebo effect, she said, because “non–drug-related side effects of medications are often greatest during the initial weeks of treatment and tend to abate over time.” For example, “metformin causes diarrhea and beta-blockers cause fatigue, but subjects do adapt and generally tolerate them very well.”
The patients, 25 women and 35 men, 90% of whom were white, received four pill bottles, each with a month’s supply of atorvastatin, four bottles each with 1 month of placebo, and four empty bottles each, to be used double blind for a month in randomized order.
Patients used the smartphone app to document their symptom scores, which ranged from 0 for no symptoms to 100 for symptoms that were the “worst imaginable,” the published report noted. Patients who experienced symptoms so severe as to be intolerable could stop the 1-month regimen they were then following, with instructions to resume the regimens in order starting the next month.
Eleven patients were unable to complete all 12 1-month segments of the trial.
The study’s overall “nocebo ratio” of 0.90 was calculated as the difference between symptom intensity scores on placebo and on no treatment divided by the difference between symptom intensity on the statin and on no treatment. The interpretation: 90% of the symptom burden felt by patients receiving atorvastatin was also felt during placebo use.
A total of 30 patients, contacted 6 months after the trial concluded, had resumed taking a statin, while “4 planned to do so and one could not be contacted,” the report noted. The 25 other patients weren’t receiving a statin and had no plans to take one.
In an important part of the trial, Dr. Howard said, at its conclusion the patients were shown their pattern of symptoms in relation to whether they were taking the statin, placebo, or neither. “Participants could see as clearly as we could the surprisingly powerful magnitude of the nocebo effect. And this led to half of our patients happily restarting statins.”
The implications of SAMSON, Dr. Welty said, “are very important, in that those developing symptoms within 2 weeks of starting a statin should be reassured that approximately half will be able to successful restart the statin.”
SAMSON was funded by the British Heart Foundation. Howard had no disclosures. Dr. Welty disclosed chairing the data safety monitoring committee for Empagliflozin International Clinical Trials, supported by Boehringer Ingelheim.

STRENGTH trial questions CV benefit of high-dose omega-3s
Questions about the cardiovascular benefit of omega-3 fatty acids and the high-dose eicosapentaenoic acid (EPA) product, icosapent ethyl (Vascepa, Amarin), have resurfaced with the presentation and publication of the STRENGTH trial using a combined high-dose omega-3 fatty acid product.
The STRENGTH trial showed no benefit on cardiovascular event rates of a high-dose combination of EPA and docosahexaenoic acid (DHA) in a new branded product (Epanova, AstraZeneca).
It was announced in January that the trial was being stopped because of a low likelihood of showing any benefit.
Full results were presented Nov. 15 at the virtual American Heart Association scientific sessions and simultaneously published online in JAMA.
These results showed similar cardiovascular event rates with the high-dose EPA/DHA product and placebo, with a hazard ratio for the primary endpoint of 0.99. In addition to no benefit, more adverse effects occurred in the active treatment arm, with a higher rate of gastrointestinal adverse events and atrial fibrillation.
“We found no benefit of a high-dose combination of EPA and DHA. Despite a 270% to 300% increase in EPA, the hazard curves for the active and placebo groups were superimposable,” STRENGTH investigator A. Michael Lincoff, MD, of the Cleveland Clinic, said at the AHA meeting.
The big question is how the negative results of the STRENGTH trial can be reconciled with the very positive results of the REDUCE-IT trial, which showed an impressive 25% relative risk reduction in major adverse cardiovascular events with the high-dose purified EPA product, icosapent ethyl.
Dr. Lincoff proposed several possible explanations for the different results between these two trials, although he cautioned that all explanations were speculative.
The one explanation that Dr. Lincoff highlighted in particular was the different placebos used in the two trials. REDUCE-IT used a placebo of mineral oil, which Dr. Lincoff noted increases LDL, apolipoprotein B, and high-sensitivity C-reactive protein, whereas the corn oil placebo used in STRENGTH “is truly neutral on a broad range lipid and cardiovascular biomarkers,” he said.
“It must therefore be considered that at least part of the benefit in REDUCE-IT is due to an increase in adverse cardiovascular event rate in the control arm, and our results from STRENGTH cast uncertainly on the net benefit or harm of any omega-3 fatty acid preparation,” Dr. Lincoff said.
Asked whether he used omega-3 fatty acids in his practice, Dr. Lincoff replied, “Aside from patients with triglycerides greater than 500 – for which there is other evidence of benefit – I do not routinely prescribe omega-3 fatty acids. For the reasons discussed, I think there are questions about whether the risks and benefits have a favorable ratio.”
Asked at an AHA press conference what advice he would give to other physicians on the use of Vascepa, Dr. Lincoff said, “On the one hand, we could take the REDUCE-IT study results at face value, but there are potential concerns on the construct of that trial and whether the effects were exaggerated. That having been said, the [Food and Drug Administration] has approved that initial indication, so this is not a straightforward issue of whether or not that trial result is valid.
“What I would like to see is a trial in future with a clearly neutral comparator. It’s hard to recommend taking your patients off Vascepa now, but I have a high threshold at this point to start patients on it because of these concerns,” he added.
A “manufactured controversy”
The lead investigator of the REDUCE-IT trial, Deepak L. Bhatt, MD, professor of medicine, Harvard Medical School, Boston, described Dr. Lincoff’s comments as “absurd.”
In an interview, he said the Japanese JELIS trial, while having some limitations, also showed a benefit of icosapent ethyl, which “in the context of this manufactured controversy about the mineral oil placebo in REDUCE-IT, completely rebuts concerns about the placebo in REDUCE-IT being toxic.”
Dr. Bhatt also suggested that DHA may counter some of the benefits of EPA. “It appears that the STRENGTH trial leadership is trying to stir up controversy, rather than just reporting objectively that they have a negative trial,” he added.
Dr. Lincoff outlined other possible explanations for the difference between the two trials.
He noted that icosapent ethyl increased levels of EPA by 45% in REDUCE-IT more than did the combined product used in STRENGTH. “But this moderate difference seems insufficient to account for the markedly different results of the two trials,” Dr. Lincoff added, “and both trials showed a 19% reduction in triglycerides, suggesting they have similar biochemical effects.”
There is also the possibility of an adverse effect of DHA, he noted, “but this has never been seen in previous studies.”
Another explanation could be differences in trial populations, with REDUCE-IT including more patients with established cardiovascular disease. “But the results were no different in this group compared to the patients without established cardiovascular disease, so this explanation is unlikely,” Dr. Lincoff suggested.
STRENGTH trial
The STRENGTH trial included 13,078 statin-treated participants with high cardiovascular risk, hypertriglyceridemia, and low levels of HDL cholesterol from 22 countries.
They were randomly assigned to a 4 g per day of carboxylic acid formulation of EPA and DHA or to corn oil as an inert comparator.
The trial was halted when 1,384 patients had experienced a primary endpoint event (of a planned 1,600 events), based on an interim analysis that indicated a low probability of clinical benefit of the active treatment.
At this point, the primary efficacy endpoint – a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina requiring hospitalization – occurred in 12.0% of patients treated with the omega-3 product vs. 12.2% of those who received corn oil (hazard ratio [HR], 0.99; P = .84).
A greater rate of gastrointestinal adverse events was observed in the omega-3 group (24.7%) than in corn oil–treated patients (14.7%). An increased rate of new-onset atrial fibrillation was also observed in the omega-3 group (2.2% vs 1.3%; HR, 1.69).
Uncertainty prevails
The moderator of an AHA press conference at which the STRENGTH trial was discussed, Amit Khera, MD, professor of medicine and director of preventive cardiology at UT Southwestern Medical Center, Dallas, said in an interview that questions about how Vascepa brought about the benefits shown in REDUCE-IT have been ongoing since that trial was published.
“I think for now, we have to accept the REDUCE-IT results as a positive finding. However, the STRENGTH trial did amplify these questions a bit since there was no signal at all for benefit, and this heightens the call for additional trials of high-dose EPA formulations, including icosapent ethyl, versus corn oil or another neutral comparator,” he said.
Discussant of the STRENGTH trial at the AHA late-breaker session, Alberico Catapano, MD, PhD, University of Milan, noted that DHA may have less biological activity than EPA.
“We don’t know for certain, but there are studies suggesting that EPA may have more effect on stabilizing plaque membranes,” Dr. Catapano said. “Certainly, the dose of EPA was different in the two studies, and in my view this could be part of the explanation. But we are still in place where we need more evidence.”
In an editorial accompanying the JAMA publication of STRENGTH, Garima Sharma, MD, Seth S. Martin, MD, and Roger S. Blumenthal, MD, Johns Hopkins University, Baltimore, said the trial’s findings “may invigorate further investigation regarding IPE [icosapent ethyl], generate additional constructive debate around the optimal placebo control, and should prompt reconsideration of over-the-counter mixed omega-3 fatty acid products for ASCVD [atherosclerotic cardiovascular disease] prevention.
“This latter point is especially important given the lack of evidence for benefit, and the potential for harm due to increased AF [atrial fibrillation],” they noted.
“The reasons the findings from the REDUCE-IT trial were positive and the STRENGTH trial were not, and that EPA levels correlated with outcomes in REDUCE-IT but did not in STRENGTH, remain uncertain,” they concluded. “The importance of the specific omega-3 formulation in achieving ASCVD risk reduction and the degree to which the placebo (i.e., mineral oil vs corn oil) may have affected outcomes remain unresolved.”
The STRENGTH trial was sponsored by AstraZeneca. Dr. Lincoff reported receiving grants from AstraZeneca during the conduct of the study. Dr. Catapano has received honoraria, lecture fees, or research grants from Sigma-Tau, Manarini, Kowa Pharmaceuticals, Recordati, Eli Lilly, AstraZeneca, Mediolanum, Pfizer, Merck, Sanofi, Aegerion, Amgen, Genzyme, Bayer, Sanofi, Regeneron Daiichi Sankyo, and Amarin. Dr. Martin reports receiving consulting fees from AstraZeneca, Amgen, Esperion, and REGENXBIO, and has a patent pending for a system of LDL-C estimation filed by Johns Hopkins University. Dr. Bhatt reports serving as principal investigator for REDUCE-IT and that Brigham and Women’s Hospital has received research funding from Amarin.

Questions about the cardiovascular benefit of omega-3 fatty acids and the high-dose eicosapentaenoic acid (EPA) product, icosapent ethyl (Vascepa, Amarin), have resurfaced with the presentation and publication of the STRENGTH trial using a combined high-dose omega-3 fatty acid product.
The STRENGTH trial showed no benefit on cardiovascular event rates of a high-dose combination of EPA and docosahexaenoic acid (DHA) in a new branded product (Epanova, AstraZeneca).
It was announced in January that the trial was being stopped because of a low likelihood of showing any benefit.
Full results were presented Nov. 15 at the virtual American Heart Association scientific sessions and simultaneously published online in JAMA.
These results showed similar cardiovascular event rates with the high-dose EPA/DHA product and placebo, with a hazard ratio for the primary endpoint of 0.99. In addition to no benefit, more adverse effects occurred in the active treatment arm, with a higher rate of gastrointestinal adverse events and atrial fibrillation.
“We found no benefit of a high-dose combination of EPA and DHA. Despite a 270% to 300% increase in EPA, the hazard curves for the active and placebo groups were superimposable,” STRENGTH investigator A. Michael Lincoff, MD, of the Cleveland Clinic, said at the AHA meeting.
The big question is how the negative results of the STRENGTH trial can be reconciled with the very positive results of the REDUCE-IT trial, which showed an impressive 25% relative risk reduction in major adverse cardiovascular events with the high-dose purified EPA product, icosapent ethyl.
Dr. Lincoff proposed several possible explanations for the different results between these two trials, although he cautioned that all explanations were speculative.
The one explanation that Dr. Lincoff highlighted in particular was the different placebos used in the two trials. REDUCE-IT used a placebo of mineral oil, which Dr. Lincoff noted increases LDL, apolipoprotein B, and high-sensitivity C-reactive protein, whereas the corn oil placebo used in STRENGTH “is truly neutral on a broad range lipid and cardiovascular biomarkers,” he said.
“It must therefore be considered that at least part of the benefit in REDUCE-IT is due to an increase in adverse cardiovascular event rate in the control arm, and our results from STRENGTH cast uncertainly on the net benefit or harm of any omega-3 fatty acid preparation,” Dr. Lincoff said.
Asked whether he used omega-3 fatty acids in his practice, Dr. Lincoff replied, “Aside from patients with triglycerides greater than 500 – for which there is other evidence of benefit – I do not routinely prescribe omega-3 fatty acids. For the reasons discussed, I think there are questions about whether the risks and benefits have a favorable ratio.”
Asked at an AHA press conference what advice he would give to other physicians on the use of Vascepa, Dr. Lincoff said, “On the one hand, we could take the REDUCE-IT study results at face value, but there are potential concerns on the construct of that trial and whether the effects were exaggerated. That having been said, the [Food and Drug Administration] has approved that initial indication, so this is not a straightforward issue of whether or not that trial result is valid.
“What I would like to see is a trial in future with a clearly neutral comparator. It’s hard to recommend taking your patients off Vascepa now, but I have a high threshold at this point to start patients on it because of these concerns,” he added.
A “manufactured controversy”
The lead investigator of the REDUCE-IT trial, Deepak L. Bhatt, MD, professor of medicine, Harvard Medical School, Boston, described Dr. Lincoff’s comments as “absurd.”
In an interview, he said the Japanese JELIS trial, while having some limitations, also showed a benefit of icosapent ethyl, which “in the context of this manufactured controversy about the mineral oil placebo in REDUCE-IT, completely rebuts concerns about the placebo in REDUCE-IT being toxic.”
Dr. Bhatt also suggested that DHA may counter some of the benefits of EPA. “It appears that the STRENGTH trial leadership is trying to stir up controversy, rather than just reporting objectively that they have a negative trial,” he added.
Dr. Lincoff outlined other possible explanations for the difference between the two trials.
He noted that icosapent ethyl increased levels of EPA by 45% in REDUCE-IT more than did the combined product used in STRENGTH. “But this moderate difference seems insufficient to account for the markedly different results of the two trials,” Dr. Lincoff added, “and both trials showed a 19% reduction in triglycerides, suggesting they have similar biochemical effects.”
There is also the possibility of an adverse effect of DHA, he noted, “but this has never been seen in previous studies.”
Another explanation could be differences in trial populations, with REDUCE-IT including more patients with established cardiovascular disease. “But the results were no different in this group compared to the patients without established cardiovascular disease, so this explanation is unlikely,” Dr. Lincoff suggested.
STRENGTH trial
The STRENGTH trial included 13,078 statin-treated participants with high cardiovascular risk, hypertriglyceridemia, and low levels of HDL cholesterol from 22 countries.
They were randomly assigned to a 4 g per day of carboxylic acid formulation of EPA and DHA or to corn oil as an inert comparator.
The trial was halted when 1,384 patients had experienced a primary endpoint event (of a planned 1,600 events), based on an interim analysis that indicated a low probability of clinical benefit of the active treatment.
At this point, the primary efficacy endpoint – a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina requiring hospitalization – occurred in 12.0% of patients treated with the omega-3 product vs. 12.2% of those who received corn oil (hazard ratio [HR], 0.99; P = .84).
A greater rate of gastrointestinal adverse events was observed in the omega-3 group (24.7%) than in corn oil–treated patients (14.7%). An increased rate of new-onset atrial fibrillation was also observed in the omega-3 group (2.2% vs 1.3%; HR, 1.69).

Evinacumab, novel lipid-lowerer, extends promise in phase 2 results
Treatment with evinacumab, an investigational lipid-lowering drug with a novel mechanism of action, safely led to roughly a halving of LDL cholesterol levels in patients with treatment-refractory hypercholesterolemia in a multicenter, phase 2 study of 272 patients treated for 16 weeks.
The study enrolled patients with either heterozygous familial hypercholesterolemia (FH) (72% of patients), or patients with hypercholesterolemia and clinical evidence of atherosclerotic cardiovascular disease who had failed to reached their recommended level of LDL cholesterol by treatment (when tolerated) with a statin, ezetimibe, and a PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitor.
Notably, only 8 of the 272 randomized patients entered the study not on treatment with a PCSK9 inhibitor. Despite these background treatments, all enrolled patients were above their goal LDL-cholesterol level, with an average level of 148 mg/dL.
The study’s primary endpoint was the percent change from baseline in LDL cholesterol after 16 weeks compared with placebo among patients treated with subcutaneous drug delivery either weekly or every other week, and among patients treated with intravenous delivery every 4 weeks. Results of the dose-ranging study showed that the highest subcutaneous dosage tested produced a 56% cut in LDL cholesterol, while the highest IV dosage led to a 51% drop, Robert S. Rosenson, MD, said at the virtual scientific sessions of the American Heart Association. Concurrently with his report, the results were published online in the New England Journal of Medicine.
The drug’s safety among 194 patients who received evinacumab was “reassuring,” said Dr. Rosenson, professor of medicine and director of the cardiometabolic disorders unit at Icahn School of Medicine at Mount Sinai in New York. “I see no concerning signals in the safety profile,” he said in an interview, an assessment that other experts shared.
“Safety looks pretty good. I don’t see any major concerns,” said lipidologist and endocrinologist Anne C. Goldberg, MD, professor of medicine at Washington University in St. Louis. The LDL-cholesterol effect shown was “very, very impressive in these hard to treat patients,” added Dr. Goldberg, who was a coinvestigator on the study.
“Nothing stands out” as a safety concern in the new data, agreed Robert H. Eckel, MD, an endocrinologist and lipid specialist at the University of Colorado in Aurora.
Drug’s unique mechanism extends potential benefits
The phase 2 study included dose-ranging assessments of both subcutaneous and intravenous treatment with evinacumab, a fully human monoclonal antibody against angiopoietin-like 3, an enzyme that inhibits two different lipases involved in metabolizing LDL cholesterol and other lipoproteins including triglycerides. When the drug inhibits angiopoietin-like 3, the lipases remain more active and further reduce levels of their target lipoproteins.
“The powerful contribution of this drug is that it works by a pathway independent of the LDL receptor,” said Dr. Rosenson.
By this mechanism evinacumab cut not only LDL cholesterol, but also lowered triglycerides by 53%-62% at the highest dosages, an effect seen as a potential plus. “Prospects are favorable for a drug that not only lowers atherogenic lipoproteins but also lowers triglycerides [TGs]. That’s a distinguishing feature of this treatment,” compared with other agents that lower LDL cholesterol, Dr. Rosenson said. It could make evinacumab especially attractive for treating patients with diabetes, who often have elevated TG levels, he noted. But Dr. Eckel cautioned that a clinical benefit directly linked to TG lowering has not yet been proven.
The drug also cut HDL cholesterol by an average of as much as 31% from baseline, though the consequence of this effect isn’t clear. “I’m not worried about the HDL levels,” said Dr. Goldberg, who noted that changes in HDL cholesterol produced by drug treatment have often not shown discernible effects.
Reaching goals by IV or subcutaneous delivery
Another measure of evinacumab’s efficacy was the percentage of patients who fell below the LDL-cholesterol threshold of 70 mg/dL set by recommendations of the American Heart Association and American College of Cardiology for the highest risk patients, and the less than 55 mg/dL goal set for similar patients by the European Society of Cardiology. Among the subcutaneously-treated patients, 64% achieved the goal of less than 70 mg/dL, and 49% hit the goal of less than 55 mg/dL. Among those who received IV treatment, 71% fell below the 70 mg/dL threshold, and 50% dropped below 55 mg/dL.
The good efficacy shown with subcutaneous dosing is critical, noted Dr. Eckel, as this represents a new dimension for evinacumab that had previously been tested only as an IV agent in patients with homozygous FH (N Engl J Med. 2020 Aug 20;383[8]:711-20).
“Subcutaneous delivery is needed for wide real world use,” Dr. Eckel noted in an interview.
Evinacumab’s role hangs on further studies
The path that evinacumab takes from here into U.S. practice is not yet clear, said Dr. Rosenson. He cited the approval earlier in 2020 of another LDL-lowering drug, bempedoic acid (Nexletol) that received U.S. regulatory approval for a similar patient population after studies that proved only lipid-lowering safety and efficacy, without any clinical-endpoint data. He wondered: “Will the [Food and Drug Administration] require a cardiovascular outcomes trial” for evinacumab?
The growing experience using the PCSK9 inhibitor antibodies to treat hyperlipidemia has made clinicians comfortable with this general approach to lipid management, but if evinacumab never accumulates similar efficacy evidence that may relegate it to the backseat compared with the PCSK9 inhibitors for quite some time, suggested Dr. Goldberg, though she said she’d be willing to prescribe evinacumab to selected patients based on lipid-lowering evidence alone.
By providing an alternative mechanism for lipid lowering, evinacumab can serve as a useful add-on for patients not reaching their LDL-cholesterol goal with more established agents, thereby providing an alternative to LDL apheresis, which now serves as the lipid-lowering therapy of last resort, said both Dr. Rosenson and Dr. Goldberg.
The study was sponsored by Regeneron, the company developing evinacumab. Dr. Rosenson has been a consultant to Regeneron, and has also been a consultant to or received research funding from Amgen, 89Bio, Corvidia, CVS Caremark, Kowa, Novartis, and The Medicines Company. Dr. Goldberg has received research grants, personal fees, and nonfinancial support from Regeneron and Sanofi, research grants from Amarin, Amgen, Ionis/AKCEA, Novartis, and Pfizer, and personal fees from AKCEA, Esperion, Merck and Novartis. Dr. Eckel has been a consultant to KOWA and Novo Nordisk.

The study enrolled patients with either heterozygous familial hypercholesterolemia (FH) (72% of patients), or patients with hypercholesterolemia and clinical evidence of atherosclerotic cardiovascular disease who had failed to reached their recommended level of LDL cholesterol by treatment (when tolerated) with a statin, ezetimibe, and a PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitor.
Notably, only 8 of the 272 randomized patients entered the study not on treatment with a PCSK9 inhibitor. Despite these background treatments, all enrolled patients were above their goal LDL-cholesterol level, with an average level of 148 mg/dL.
The study’s primary endpoint was the percent change from baseline in LDL cholesterol after 16 weeks compared with placebo among patients treated with subcutaneous drug delivery either weekly or every other week, and among patients treated with intravenous delivery every 4 weeks. Results of the dose-ranging study showed that the highest subcutaneous dosage tested produced a 56% cut in LDL cholesterol, while the highest IV dosage led to a 51% drop, Robert S. Rosenson, MD, said at the virtual scientific sessions of the American Heart Association. Concurrently with his report, the results were published online in the New England Journal of Medicine.
The drug’s safety among 194 patients who received evinacumab was “reassuring,” said Dr. Rosenson, professor of medicine and director of the cardiometabolic disorders unit at Icahn School of Medicine at Mount Sinai in New York. “I see no concerning signals in the safety profile,” he said in an interview, an assessment that other experts shared.
“Safety looks pretty good. I don’t see any major concerns,” said lipidologist and endocrinologist Anne C. Goldberg, MD, professor of medicine at Washington University in St. Louis. The LDL-cholesterol effect shown was “very, very impressive in these hard to treat patients,” added Dr. Goldberg, who was a coinvestigator on the study.
“Nothing stands out” as a safety concern in the new data, agreed Robert H. Eckel, MD, an endocrinologist and lipid specialist at the University of Colorado in Aurora.
Drug’s unique mechanism extends potential benefits
The phase 2 study included dose-ranging assessments of both subcutaneous and intravenous treatment with evinacumab, a fully human monoclonal antibody against angiopoietin-like 3, an enzyme that inhibits two different lipases involved in metabolizing LDL cholesterol and other lipoproteins including triglycerides. When the drug inhibits angiopoietin-like 3, the lipases remain more active and further reduce levels of their target lipoproteins.
“The powerful contribution of this drug is that it works by a pathway independent of the LDL receptor,” said Dr. Rosenson.
By this mechanism evinacumab cut not only LDL cholesterol, but also lowered triglycerides by 53%-62% at the highest dosages, an effect seen as a potential plus. “Prospects are favorable for a drug that not only lowers atherogenic lipoproteins but also lowers triglycerides [TGs]. That’s a distinguishing feature of this treatment,” compared with other agents that lower LDL cholesterol, Dr. Rosenson said. It could make evinacumab especially attractive for treating patients with diabetes, who often have elevated TG levels, he noted. But Dr. Eckel cautioned that a clinical benefit directly linked to TG lowering has not yet been proven.
The drug also cut HDL cholesterol by an average of as much as 31% from baseline, though the consequence of this effect isn’t clear. “I’m not worried about the HDL levels,” said Dr. Goldberg, who noted that changes in HDL cholesterol produced by drug treatment have often not shown discernible effects.
Reaching goals by IV or subcutaneous delivery
Another measure of evinacumab’s efficacy was the percentage of patients who fell below the LDL-cholesterol threshold of 70 mg/dL set by recommendations of the American Heart Association and American College of Cardiology for the highest risk patients, and the less than 55 mg/dL goal set for similar patients by the European Society of Cardiology. Among the subcutaneously-treated patients, 64% achieved the goal of less than 70 mg/dL, and 49% hit the goal of less than 55 mg/dL. Among those who received IV treatment, 71% fell below the 70 mg/dL threshold, and 50% dropped below 55 mg/dL.
The good efficacy shown with subcutaneous dosing is critical, noted Dr. Eckel, as this represents a new dimension for evinacumab that had previously been tested only as an IV agent in patients with homozygous FH (N Engl J Med. 2020 Aug 20;383[8]:711-20).
“Subcutaneous delivery is needed for wide real world use,” Dr. Eckel noted in an interview.
Evinacumab’s role hangs on further studies
The path that evinacumab takes from here into U.S. practice is not yet clear, said Dr. Rosenson. He cited the approval earlier in 2020 of another LDL-lowering drug, bempedoic acid (Nexletol) that received U.S. regulatory approval for a similar patient population after studies that proved only lipid-lowering safety and efficacy, without any clinical-endpoint data. He wondered: “Will the [Food and Drug Administration] require a cardiovascular outcomes trial” for evinacumab?
The growing experience using the PCSK9 inhibitor antibodies to treat hyperlipidemia has made clinicians comfortable with this general approach to lipid management, but if evinacumab never accumulates similar efficacy evidence that may relegate it to the backseat compared with the PCSK9 inhibitors for quite some time, suggested Dr. Goldberg, though she said she’d be willing to prescribe evinacumab to selected patients based on lipid-lowering evidence alone.
By providing an alternative mechanism for lipid lowering, evinacumab can serve as a useful add-on for patients not reaching their LDL-cholesterol goal with more established agents, thereby providing an alternative to LDL apheresis, which now serves as the lipid-lowering therapy of last resort, said both Dr. Rosenson and Dr. Goldberg.
The study was sponsored by Regeneron, the company developing evinacumab. Dr. Rosenson has been a consultant to Regeneron, and has also been a consultant to or received research funding from Amgen, 89Bio, Corvidia, CVS Caremark, Kowa, Novartis, and The Medicines Company. Dr. Goldberg has received research grants, personal fees, and nonfinancial support from Regeneron and Sanofi, research grants from Amarin, Amgen, Ionis/AKCEA, Novartis, and Pfizer, and personal fees from AKCEA, Esperion, Merck and Novartis. Dr. Eckel has been a consultant to KOWA and Novo Nordisk.

Chronic inflammatory diseases vary widely in CHD risk
Not all chronic systemic inflammatory diseases are equal enhancers of atherosclerotic cardiovascular disease risk, according to a large case-control study.
Current AHA/American College of Cardiology guidelines cite three chronic inflammatory diseases as atherosclerotic cardiovascular disease risk enhancers: rheumatoid arthritis, psoriasis, and HIV infection. But this study of those three diseases, along with three others marked by elevated high sensitivity C-reactive protein (systemic sclerosis, inflammatory bowel disease, and systemic lupus erythematosus [SLE]), showed that chronic inflammatory diseases are not monolithic in terms of their associated risk of incident coronary heart disease (CHD).
Indeed, two of the six inflammatory diseases – psoriasis and inflammatory bowel disease – turned out to be not at all associated with increased cardiovascular risk in the 37,117-patient study. The highest-risk disease was SLE, not specifically mentioned in the guidelines, Arjun Sinha, MD, a cardiology fellow at Northwestern University, Chicago, noted in his presentation at the virtual American Heart Association scientific sessions.
The study included 18,129 patients with one of the six chronic inflammatory diseases and 18,988 matched controls, none with CHD at baseline. All regularly received outpatient care at Northwestern during 2000-2019. There were 1,011 incident CHD events during a median of 3.5 years of follow-up.
In a Cox proportional hazards analysis adjusted for demographics, insurance status, hypertension, diabetes, current smoking, total cholesterol, and estimated glomerular filtration rate, here’s how the chronic inflammatory diseases stacked up in terms of incident CHD and MI risks:
- SLE: hazard ratio for CHD, 2.85; for MI, 4.76.
- Systemic sclerosis: HR for CHD, 2.14; for MI, 3.19.
- HIV: HR for CHD, 1.38; for MI, 1.69.
- Rheumatoid arthritis: HR for CHD, 1.22; for MI, 1.45.
- Psoriasis: no significant increase.
- Inflammatory bowel disease: no significant increase.
In an exploratory analysis, Dr. Sinha and coinvestigators evaluated the risk of incident CHD stratified by disease severity. For lack of standardized disease severity scales, the investigators relied upon tertiles of CD4 T cell count in the HIV group and CRP in the others. The HR for new-onset CHD in the more than 5,000 patients with psoriasis didn’t vary by CRP tertile. However, there was a nonsignificant trend for greater disease severity, as reflected by CRP tertile, to be associated with increased incident CHD risk in the HIV and inflammatory bowel disease groups.
In contrast, patients with rheumatoid arthritis or systemic sclerosis who were in the top CRP tertile had a significantly greater risk of developing CHD than that of controls, with HRs of 2.11 in the rheumatoid arthritis group and 4.59 with systemic sclerosis, although patients in the other two tertiles weren’t at significantly increased risk. But all three tertiles of CRP in patients with SLE were associated with significantly increased CHD risk: 3.17-fold in the lowest tertile of lupus severity, 5.38-fold in the middle tertile, and 4.04-fold in the top tertile for inflammation.
These findings could be used in clinical practice to fine-tune atherosclerotic cardiovascular disease risk assessment based upon chronic inflammatory disease type and severity. That’s information which in turn can help guide the timing and intensity of preventive therapy for patients with each disease type.
But studying the association between chronic systemic inflammatory diseases and CHD risk can be useful in additional ways, according to Dr. Sinha. These inflammatory diseases can serve as models of atherosclerosis that shed light on the non–lipid-related mechanisms involved in cardiovascular disease.
“The gradient in risk may be hypothesis-generating with respect to which specific inflammatory pathways may contribute to CHD,” he explained.
Each of these six chronic inflammatory diseases is characterized by a different form of major immune dysfunction, Dr. Sinha continued. A case in point is SLE, the inflammatory disease associated with the highest risk of CHD and MI. Lupus is characterized by a form of neutrophil dysfunction marked by increased formation and reduced degradation of neutrophil extracellular traps, or NETs, as well as by an increase in autoreactive B cells and dysfunctional CD4+ T helper cells. The increase in NETs of of particular interest because NETs have also been shown to contribute to the development of atherosclerosis, endothelial dysfunction, plaque erosion, and thrombosis.
In another exploratory analysis, Dr. Sinha and coworkers found that SLE patients with a neutrophil count above the median level were twice as likely to develop CHD than were those with a neutrophil count below the median.
A better understanding of the upstream pathways linking NET formation in SLE and atherosclerosis could lead to development of new or repurposed medications that target immune dysfunction in order to curb atherosclerosis, said Dr. Sinha, whose study won the AHA’s Samuel A. Levine Early Career Clinical Investigator Award.
He reported having no financial conflicts regarding his study.

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.

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.

Omega-3 caps, vitamin D both fail for atrial fib primary prevention: VITAL-Rhythm
Clinical trials of omega-3 fatty acid or vitamin D supplements have followed a long and winding road in search of benefits in cardiovascular (CV) disease, with wildly mixed results. But the journey may be in vain in one of cardiology’s frontier research areas, primary prevention of atrial fibrillation (AF), suggest primary results of the VITAL-Rhythm trial, presented Nov. 13 during the American Heart Association (AHA) Scientific Sessions 2020 virtual meeting.
Neither marine-oil caps nor the vitamin D3 supplements made a difference to risk for incident AF, whether paroxysmal or persistent, over more than 5 years in the study, with more than 25,000 adults in the community. Nor did they seem to cause harm.
“To our knowledge, this is the first large-scale, long-term, randomized placebo-controlled trial to test the effect of any intervention on incident AF,” Christine M. Albert, MD, MPH, Cedars-Sinai Medical Center in Los Angeles, said at a media briefing on VITAL-Rhythm before her formal presentation of the trial during the conference.
Its findings, she said, don’t support the use of marine-oil caps or vitamin D3 for primary prevention of incident AF. “Fortunately, they also do not show any increased risk in atrial fibrillation for patients who are using these supplements for other indications.”
Both agents are widely taken without physician supervision for their perceived benefits, and marine-oil caps in particular – often in special prescription formulations – may be used for reducing elevated triglyceride levels and, based on the results of REDUCE-IT, cutting cardiovascular risk.
“It’s pretty clear that there’s no evidence to suggest that either of these supplements is helpful for preventing atrial fibrillation. And I think that’s clear from the evidence these investigators presented,” said Jonathan P. Piccini, MD, MHS, Duke University, Durham, N.C., who wasn’t part of the study.
“It’s also a little disappointing because atrial fibrillation is such a huge problem, and the inability to identify preventative strategies is a repeated theme,” he said in an interview.
VITAL-Rhythm is an ancillary study within the VITAL trial, which showed no benefit from either supplement regarding risk for incident cancer or CV events, as reported at the AHA sessions 2 years ago. In fact, their effects seem sweepingly negative throughout the trial; in another ancillary study, VITAL-DKD, neither supplement helped preserve renal function over 5 years in patients with type 2 diabetes.
The participants started VITAL without a history of AF, CV disease, or cancer; they were randomly assigned to take about a gram of omega-3 fatty acids, 2000 IU vitamin D3 daily, or their placebos, in a double randomization.
VITAL and its ancillary studies collectively undercut mechanistic theories about how omega-3 fatty acid and vitamin D supplements may affect AF risk, ideas derived from epidemiologic and dietary studies. They were thought perhaps “to have direct antiarrhythmic effects on myocytes through effects on ion channels, electrical remodeling, electrical stabilizing effects, and fluidity of the cell membranes,” observed Renate B. Schnabel, MD, MSc, University Heart Center, Hamburg, Germany, at the briefing. Or such effects might be related to beneficial effects on atherosclerosis, inflammation, or ischemic heart disease, she noted.
Neither idea is likely after VITAL and VITAL-Rhythm, said Dr. Schnabel, who spoke as an invited discussant after Albert’s formal presentation at AHA 2020.
That omega-3 fatty acid supplements may not improve AF incidence or risks has also been evident from many clinical trials and observational studies. Several, including REDUCE-IT, included some evidence for increasing risk for AF with marine-oil supplement intake. That may have happened in VITAL-Rhythm as well.
“While there was no evidence that the omega-3 three fatty acids prevented atrial fibrillation, there was a signal of perhaps more atrial fibrillation in the omega-3 fatty-acids group,” said Dr. Piccini, who directs his center’s electrophysiology clinical trials program.
A sensitivity analysis limited to participants who adhered to their assigned regimens, as opposed to the main intention-to-treat (ITT) analysis, showed a nonsignificant 13% increased hazard ratio for incident AF for the marine-oil supplement group. It reached a P value of .09, which can be interpreted as a trend.
“There are a few studies that have now showed a trend or an increased incidence of arrhythmia in patients treated with omega-3 fatty acids,” Dr. Piccini noted. “I don’t think it’s definitive, but it’s certainly something to keep an eye on.”
VITAL-Rhythm included an electrocardiography (ECG) substudy, yet to be reported, that should yield more insights about any such effects of marine-oil or vitamin D supplements in the trial, Dr. Albert said at the briefing.
The ancillary study assigned its 25,119 patients (mean age, 67 years; 51% women) to take vitamin D3 at 2000 IU/day, marine-oil supplements containing omega-3 fatty acids at 840 mg per day – 460 mg eicosapentaenoic acid (EPA) plus 380 mg docosahexaenoic acid (DHA) (Omacor, Pronova BioPharma) – or their placebos in a 2 x 2 randomization.
Incident cases of AF were identified through annual questionnaires in which the participants self-reported whether they had received a physician diagnosis of the arrhythmia, supplemented by Centers for Medicare & Medicaid Services claims data for AF hospital and clinical visits. Those led to a review of inpatient and outpatient records, from which AF events were adjudicated by an endpoint committee.
An electrocardiogram (72.9%) or physician’s report (27.1%) confirmed the AF diagnosis as the protocol required.
By those standards, 900 incident cases were identified, for a rate of 3.6% over a median of 5.3 years. They were paroxysmal in 58.4%, persistent in 38.4%, and indeterminant in 3.1%, Dr. Albert reported.
Of the 12,542 patients assigned to marine-oil caps by ITT, 469 (3.74%) developed incident AF in the ITT analysis, compared to 431 of 12,577 (3.43%) who received placebo, for an adjusted hazard ratio (HR) of 1.09 (95% CI, 0.96-1.24; P = .19).
The results were similar in two sensitivity analyses, one of which omitted patients with AF who may have had symptoms before randomization and another excluding those whose incident AF was identified solely in CMS data. But in the third “on treatment” sensitivity analysis, the HR for events was 1.13 (95% CI, 0.98-1.30; P = .09).
Outcomes for the vitamin D randomization were nearly the same, for an HR of 1.09 (95% CI, 0.96-1.25; P = .19) by ITT; the results were similar in all three sensitivity analyses.
“It’s not a tremendous signal of risk,” said Piccini of the marine-oil on-treatment analysis. But it, along with consistent evidence from other studies, does give him pause. “If a patient came to me and said,
Doctor, I want to take omega-3 fish oil, because I want to reduce my risk of events, as an arrhythmia doctor I would say, ‘We don’t have great evidence to do that for preventing atrial fibrillation. And there’s actually some evidence that it could mildly increase your risk of developing it.’ ”
For those prescribed evidence-based marine-oil therapy for other indications, he said, “I think the take-home message certainly is, if they report palpitations or other signs or symptoms that could be due to atrial fibrillation, we should be aggressive about screening for atrial fibrillation,” and making the diagnosis as appropriate. If the incident AF resolves after stopping the treatment, “maybe it’s reasonable to refrain from prescribing the medication for that patient.”
VITAL-Rhythm and VITAL are supported by multiple grants from the National Institutes of Health. Albert discloses receiving grant support from St. Jude Medical, Abbott, and Roche. Schnabel reports receiving honoraria from Bristol-Myers Squibb/Pfizer. Piccini previously disclosed receiving research grants from Abbott, the Association for the Advancement of Medical Instrumentation, Bayer, Boston Scientific, and Philips and serving as a consultant to Abbott, Allergan, ARCA Biopharma, Biotronik, Boston Scientific, LivaNova, Medtronic, Milestone, Sanofi, Philips, and UptoDate.

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.

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.
