Evidence that the heart can take a major hit in patients hospitalized with COVID-19, especially those already with cardiovascular disease (CV) or its risk factors, has been sadly apparent from the pandemic’s earliest days.

Less clear from case studies and small series to date has been whether SARS-CoV-2 directly attacks the heart and whether acute cardiac effects of the illness may lead to some kind of lingering cardiomyopathy.

The field’s grasp of those issues advanced a bit in two new reports published July 27 in JAMA Cardiology that seem to validate concerns the virus can infect the myocardium, without necessarily causing myocarditis and the possibility that some “recovered” patients may be left with persisting myocardial injury and inflammation that potentially could later manifest as heart failure.

Persisting inflammation by cardiac magnetic resonance

A prospective cohort study with 100 patients recovered from a recent bout of the disease showed evidence of ventricular dysfunction, greater ventricular mass, and in 78% of the cohort, signs of myocardial inflammation by cardiac magnetic resonance (CMR) imaging. The CMR findings correlated with elevations in troponin T by high-sensitivity assay (hs-TnT).

Two-thirds of the cohort, whose acute COVID-19 severity had “ranged from asymptomatic to minor-to-moderate symptoms,” had recovered at home, whereas the remaining “severely unwell patients” had been hospitalized, wrote the authors, led by Valentina O. Püntmann, MD, PhD, University Hospital Frankfurt (Germany).

None of the patients had a history of heart failure or cardiomyopathy, although some had hypertension, diabetes, or evidence of coronary disease.

“Our findings demonstrate that participants with a relative paucity of preexisting cardiovascular condition and with mostly home-based recovery had frequent cardiac inflammatory involvement, which was similar to the hospitalized subgroup with regards to severity and extent,” the group noted.

“There is a considerable ongoing myocardial inflammation in the heart muscle weeks after recovery from COVID-19 illness. This finding is important because it may herald a considerable burden of heart failure in a few years down the line,” Dr. Püntmann said in an interview.

Early diagnosis would offer “a good chance that early treatment could reduce the relentless course of inflammatory damage or even halt it,” she said.

“The relatively clear onset of COVID-19 illness provides an opportunity, which we often do not have with other conditions, to take a proactive action and to look for heart involvement early, within a few weeks of recovery.”

The study’s CMR evidence of inflammation edema, scarring, and pericardial effusion are among “the major diagnostic criteria for inflammatory and viral myocarditis,” observed Biykem Bozkurt, MD, PhD, from Baylor College of Medicine, Houston, who wasn’t part of either new study.

The findings suggest – consistent with previous evidence – that some patients with recent COVID-19 may be left with ongoing myocardial inflammation, and this study further adds that it could potentially become subacute or even chronic and in some may not be totally reversible, she said in an interview. How long the effects are likely to persist “remains to be determined. We need longer-term outcomes data.”

Viral presence without myocarditis

The accompanying report featured a postmortem analysis of hearts from 39 patients with mostly severe COVID-19 that pointed to a significant SARS-CoV-2 presence and signs that the virus vigorously replicated in the myocardium.

But there was no evidence that the infection led to fulminant myocarditis. Rather, the virus had apparently infiltrated the heart by localizing in interstitial cells or in macrophages that took up in the myocardium without actually entering myocytes, concluded the report’s authors, led by Diana Lindner, PhD, from the University Heart and Vascular Centre, Hamburg (Germany).

The findings suggest “that the presence of SARS-CoV-2 in cardiac tissue does not necessarily cause an inflammatory reaction consistent with clinical myocarditis,” the group wrote.

Previously in the literature, in “cases in which myocardial inflammation was present, there was also evidence of clinical myocarditis, and therefore the current cases underlie a different pathophysiology,” they concluded.

No evidence of the virus was seen in 15 cases, about 61% of the group. In 16 of the remaining 24 hearts, the viral load exceeded 1,000 copies per mcg of RNA, a substantial presence. Those 16 showed increased expression of inflammatory cytokines but no inflammatory cell infiltrates or changes in leukocyte counts, the researchers noted.

“Findings of suggested viral replication in the cases with a very high viral load are showing that we need to do more studies to find out long-term consequences, which we do not know right now,” senior author Dirk Westermann, MD, also from the University Heart and Vascular Centre, Hamburg, said.

Implications for heart failure

The postmortem findings from Dr. Lindner and associates “provide intriguing evidence that COVID-19 is associated with at least some component of myocardial injury, perhaps as the result of direct viral infection of the heart,” wrote Clyde W. Yancy, MD, MSc, from Northwestern University, Chicago, and Gregg C. Fonarow, MD, from the University of California, Los Angeles, in an editorial accompanying both reports.

The CMR study from Dr. Püntmann and colleagues – on the backdrop of earlier COVID-19 observations – suggests the potential for “residual left ventricular dysfunction and ongoing inflammation” in the months following a COVID-19 diagnosis. Both developments may be “of sufficient concern to represent a nidus for new-onset heart failure and other cardiovascular complications,” contend Dr. Yancy and Dr. Fonarow.

“When added to the postmortem pathological findings from Lindner et al, we see the plot thickening and we are inclined to raise a new and very evident concern that cardiomyopathy and heart failure related to COVID-19 may potentially evolve as the natural history of this infection becomes clearer,” they wrote.

Some patients, having recovered from the acute illness, may be left with a chronic inflammatory state that probably puts them at increased risk for future heart failure, agreed Dr. Bozkurt when interviewed. “They could show further decline in cardiac function, and their recovery might take longer than with the usual viral illnesses that we see,” she said.

“There could also be a risk of sudden death. Inflammation sometimes gives rise to sudden death and ventricular arrhythmia, which I would be very worried about, especially if the myocardium is stressed,” Dr. Bozkurt said. “So competitive sports in those patients potentially could be risky.”

COVID-19 cohort vs. matched control subjects

The CMR study from Dr. Püntmann and colleagues prospectively entered 100 patients recently recovered from an acute bout of COVID-19, either at home or at a hospital, who were followed in a registry based at University Hospital Frankfurt. Their median age was 49 years; 47% were female. They were compared with 50 age- and sex-matched control patients and 50 apparently healthy volunteers matched for risk factors, the group noted.

On the same day as the CMR assessment, the recently recovered patients, compared with the healthy control subjects and risk-factor matched control subjects, respectively, showed (P ≤ .001 in each case):

• A reduced left ventricular (LV) ejection fraction: 56% vs. 60% and 61%.
• A higher LV end-diastolic volume index: 86 mL/m² vs. 80 mL/m² and 75 mL/m^2.
• A greater LV mass index: 51 g/m² vs. 47 g/m² and 53 g/m^2.
• A higher hs-TnT level: 5.6 pg/mL vs. 3.2 pg/mL and 3.9 pg/mL.
• A greater prevalence of hs-TnT levels 3 pg/mL or more: 71% vs. 11% and 31%.

At CMR, 78% of the recovered COVID-19 patients showed abnormalities that included raised myocardial native T1 and T2 mapping, which is suggestive of fibrosis and edema from inflammation, compared with the two control groups (P < .001 for all differences), “independent of preexisting conditions, severity and overall course of the acute illness, and the time from the original diagnosis,” the group wrote. Native T1 and T2 mapping correlated significantly with hs-TnT.

“We now have the diagnostic means to detect cardiac inflammation early, and we need make every effort to apply them in every day practice,”Dr. Püntmann said in the interview.

“Using cardiac MRI will allow us to raise our game against COVID-19 and proactively develop efficient cardioprotective treatments,” she said. “Until we have effective means of protecting from the infection, that is vaccination, we must act swiftly and within the means at hand.”

The analysis evokes several other ways patients with COVID-19 might be screened for significant myocardial involvement.

“Strategies could include checking troponins, not only at admission but maybe at discharge and perhaps even those individuals who are at home and are not necessarily requiring care,” Dr. Bozkurt said.

“Biomarker profiling and screening for ongoing inflammation probably are going to be important components of COVID-19, especially for those with subclinical risk and disease.”

Dr. Westermann proposed that troponin elevations at discharge “might be a good starting point” for selecting COVID-19 patients for functional testing or imaging to screen for cardiac sequelae. Performing such tests routinely now “would be overwhelming given the massive increase in patients we still see today.”

Dr. Püntmann had no disclosures; statements of potential conflict for the other authors are in the report. Dr. Bozkurt has previously disclosed receiving consultant fees or honoraria from Bayer Healthcare, Bristol-Myers Squibb, Lantheus Medical Imaging, and Respicardia; serving on a data safety monitoring board for LivaNova USA ; and having unspecified relationships with Abbott Laboratories. Dr. Lindner had no disclosures; Dr. Westermann reported receiving personal fees from AstraZeneca, Bayer, Novartis, and Medtronic. Dr. Yancy is a deputy editor and Dr. Fonarow a section editor for JAMA Cardiology. Dr. Yancy had no other disclosures. Dr. Fonarow reported receiving personal fees from Abbott Laboratories, Amgen, AstraZeneca, Bayer, CHF Solutions, Edwards Lifesciences, Janssen, Medtronic, Merck, and Novartis.

A 10-year follow-up analysis based on one of cardiology’s most influential trials has shed further light on one of its key issues: how to sharpen selection of patients most likely to benefit from a primary prevention implantable cardioverter-defibrillator (ICD).

In a new report from SCD-HeFT, the survival advantage in patients with heart failure seen 5 years after receiving ICDs, compared with a non-ICD control group, narrowed a bit but remained significant after an additional 5 years. But not all patients with devices shared in that long-term ICD benefit. Patients with either ischemic disease or nonischemic cardiomyopathy (NICM) with devices showed a similar mortality risk reduction in the trial’s previously reported 5-year outcomes. That advantage, compared with non-ICD control patients, persisted throughout the subsequent 5 years for ischemic patients but tapered to nil for those with NICM.

The NICM patients “had what appears to be some accrual of benefit maybe out to about 6 years, and then the curves appear to come together where there’s no apparent further benefit after 6 years,” Jeanne E. Poole, MD, of the University of Washington, Seattle, said in an interview.

In both the 10-year analysis and the earlier results, ICD survival gains went preferentially to patients who enrolled with New York Heart Association (NYHA) functional class II symptoms. Patients who entered in NYHA class III “didn’t appear to have any benefit whatsoever” in either period, Dr. Poole said.

“The simple message is that the same groups of patients that benefited strongly from the ICD in the original SCD-HeFT – the NYHA class 2 patients and those with ischemic cardiomyopathy – were really the ones who benefited the greatest over the long term,” she said.

Dr. Poole is lead author on the SCD-HeFT 10-year analysis, which was published in the July 28 issue of the Journal of the American College of Cardiology.

Why the ICD survival effect disappeared midway in patients with NICM “is hard to sort out,” she said. Many in the control group were offered such devices after the trial concluded. Among those, it’s possible that disproportionately more control patients with NICM, compared with patients with ischemic disease, were fitted with ICDs that were also cardiac resynchronization therapy (CRT) devices, Dr. Poole and her colleagues speculated. That could have shifted their late outcomes to be more in line with patients who had received ICDs when the trial started.

Or “it is possible that the intermediate-term benefit of ICD therapy in NICM is overwhelmed by nonarrhythmic death in extended follow-up” given that ICDs prolong survival only by preventing arrhythmic death, noted an editorial accompanying the new SCD-HeFT publication.

Another possibility: Because NICM is a heterogeneous disorder with many potential causes, perhaps “the absence of long-term mortality benefit among SCD-HeFT participants with NICM was due to an unintended but preferential enrollment of subtypes at relatively lower risk for arrhythmic death in the longer term,” proposed Eric C. Stecker, MD, MPH, Oregon Health & Science University, Portland, and coauthors in their editorial.

“What are the take-away messages from the current analysis by Poole et al?” they asked. “These findings strongly support the clinical efficacy and cost-effectiveness of ICD therapy for the majority of patients with severe but mildly symptomatic ischemic cardiomyopathy who do not have an excessive comorbidity burden.”

But “the implications for patients with NICM are less clear,” they wrote. “Given evidence for intermediate-term benefit and the limitations inherent to assessing longer-term benefit, we do not believe it is appropriate to walk back guideline recommendations regarding ICD implantation for NICM patients.”

The findings in nonischemic patients invite comparison with the randomized DANISH trial, which entered only patients with NICM and, over more than 5 years, saw no primary-prevention ICD advantage for the end point of all-cause mortality.

But patients who received ICDs showed a reduction in arrhythmic death, a secondary end point. And mortality in the trial showed a significant interaction with patient age; survival went up sharply with ICDs for those younger than 60 years.

Also in DANISH, “the ICD treatment effect appears to vary over time, with an earlier phase showing possible survival benefit and a later phase showing attenuation of that benefit,” similar to what was seen long-term in SCD-HeFT, in which the interaction between mortality and time since implantation was significant at P = .0015, observe Dr. Poole and colleagues.

However, Dr. Poole cautioned when interviewed, patient management in DANISH, conducted exclusively in Denmark, may not have been representative of the rest of the world, complicating comparisons with other studies. For example, nearly 60% of all patients in DANISH had defibrillating CRT devices. Virtually everyone was on ACE inhibitors or angiotensin-receptor blockers, and almost 60% were taking aldosterone inhibitors.

“DANISH is an unusually high bar and probably does not reflect all patients with heart failure, and certainly does not reflect patients in the United States in terms of those high levels of guideline-directed medical therapy,” Dr. Poole said. The message from DANISH, she said, seems to be that patients with NICM who are definitely on goal-directed heart failure medications with CRT devices “probably don’t have a meaningful benefit from an ICD, on total mortality, because their sudden death rates are simply so low.”

SCD-HeFT had originally assigned 2,521 patients with heart failure of NYHA class II or III and an left ventricular ejection fraction of less than 35% to receive an ICD, amiodarone without an ICD, or an amiodarone placebo and no ICD; patients in the latter cohorts made up the non-ICD control group.

Those who received an ICD, compared with the non-ICD control patients, showed a 23% drop in all-cause mortality over a median of 45.5 months ending on October 31, 2003, Dr. Poole and colleagues noted in their current report. The trial’s primary results were unveiled 2005.

The current analysis, based on data collected in 2010 and 2011, followed the 1,855 patients alive at the trial’s official conclusion and combined outcomes before and after that time for a median follow-up of 11 years, Dr. Poole and colleagues reported.

In the ICD group, the overall hazard ratio for mortality by intention-to-treat was 0.87 (95% confidence interval, 0.76-0.98; P = .028), compared with the non-ICD control group.

A 10-year follow-up analysis based on one of cardiology’s most influential trials has shed further light on one of its key issues: how to sharpen selection of patients most likely to benefit from a primary prevention implantable cardioverter-defibrillator (ICD).

In a new report from SCD-HeFT, the survival advantage in patients with heart failure seen 5 years after receiving ICDs, compared with a non-ICD control group, narrowed a bit but remained significant after an additional 5 years. But not all patients with devices shared in that long-term ICD benefit. Patients with either ischemic disease or nonischemic cardiomyopathy (NICM) with devices showed a similar mortality risk reduction in the trial’s previously reported 5-year outcomes. That advantage, compared with non-ICD control patients, persisted throughout the subsequent 5 years for ischemic patients but tapered to nil for those with NICM.

The NICM patients “had what appears to be some accrual of benefit maybe out to about 6 years, and then the curves appear to come together where there’s no apparent further benefit after 6 years,” Jeanne E. Poole, MD, of the University of Washington, Seattle, said in an interview.

In both the 10-year analysis and the earlier results, ICD survival gains went preferentially to patients who enrolled with New York Heart Association (NYHA) functional class II symptoms. Patients who entered in NYHA class III “didn’t appear to have any benefit whatsoever” in either period, Dr. Poole said.

“The simple message is that the same groups of patients that benefited strongly from the ICD in the original SCD-HeFT – the NYHA class 2 patients and those with ischemic cardiomyopathy – were really the ones who benefited the greatest over the long term,” she said.

Dr. Poole is lead author on the SCD-HeFT 10-year analysis, which was published in the July 28 issue of the Journal of the American College of Cardiology.

Why the ICD survival effect disappeared midway in patients with NICM “is hard to sort out,” she said. Many in the control group were offered such devices after the trial concluded. Among those, it’s possible that disproportionately more control patients with NICM, compared with patients with ischemic disease, were fitted with ICDs that were also cardiac resynchronization therapy (CRT) devices, Dr. Poole and her colleagues speculated. That could have shifted their late outcomes to be more in line with patients who had received ICDs when the trial started.

Or “it is possible that the intermediate-term benefit of ICD therapy in NICM is overwhelmed by nonarrhythmic death in extended follow-up” given that ICDs prolong survival only by preventing arrhythmic death, noted an editorial accompanying the new SCD-HeFT publication.

Another possibility: Because NICM is a heterogeneous disorder with many potential causes, perhaps “the absence of long-term mortality benefit among SCD-HeFT participants with NICM was due to an unintended but preferential enrollment of subtypes at relatively lower risk for arrhythmic death in the longer term,” proposed Eric C. Stecker, MD, MPH, Oregon Health & Science University, Portland, and coauthors in their editorial.

“What are the take-away messages from the current analysis by Poole et al?” they asked. “These findings strongly support the clinical efficacy and cost-effectiveness of ICD therapy for the majority of patients with severe but mildly symptomatic ischemic cardiomyopathy who do not have an excessive comorbidity burden.”

But “the implications for patients with NICM are less clear,” they wrote. “Given evidence for intermediate-term benefit and the limitations inherent to assessing longer-term benefit, we do not believe it is appropriate to walk back guideline recommendations regarding ICD implantation for NICM patients.”

The findings in nonischemic patients invite comparison with the randomized DANISH trial, which entered only patients with NICM and, over more than 5 years, saw no primary-prevention ICD advantage for the end point of all-cause mortality.

But patients who received ICDs showed a reduction in arrhythmic death, a secondary end point. And mortality in the trial showed a significant interaction with patient age; survival went up sharply with ICDs for those younger than 60 years.

Also in DANISH, “the ICD treatment effect appears to vary over time, with an earlier phase showing possible survival benefit and a later phase showing attenuation of that benefit,” similar to what was seen long-term in SCD-HeFT, in which the interaction between mortality and time since implantation was significant at P = .0015, observe Dr. Poole and colleagues.

However, Dr. Poole cautioned when interviewed, patient management in DANISH, conducted exclusively in Denmark, may not have been representative of the rest of the world, complicating comparisons with other studies. For example, nearly 60% of all patients in DANISH had defibrillating CRT devices. Virtually everyone was on ACE inhibitors or angiotensin-receptor blockers, and almost 60% were taking aldosterone inhibitors.

“DANISH is an unusually high bar and probably does not reflect all patients with heart failure, and certainly does not reflect patients in the United States in terms of those high levels of guideline-directed medical therapy,” Dr. Poole said. The message from DANISH, she said, seems to be that patients with NICM who are definitely on goal-directed heart failure medications with CRT devices “probably don’t have a meaningful benefit from an ICD, on total mortality, because their sudden death rates are simply so low.”

Low plasma vitamin D levels emerged as an independent risk factor for COVID-19 infection and hospitalization in a large, population-based study.

Participants positive for COVID-19 were 50% more likely to have low vs normal 25(OH)D levels in a multivariate analysis that controlled for other confounders, for example.

The take home message for physicians is to “test patients’ vitamin D levels and keep them optimal for the overall health – as well as for a better immunoresponse to COVID-19,” senior author Milana Frenkel-Morgenstern, PhD, head of the Cancer Genomics and BioComputing of Complex Diseases Lab at Bar-Ilan University in Ramat Gan, Israel, said in an interview.

The study was published online July 23 in The FEBS Journal.

Previous and ongoing studies are evaluating a potential role for vitamin D to prevent or minimize the severity of SARS-CoV-2 infection, building on years of research addressing vitamin D for other viral respiratory infections. The evidence to date regarding COVID-19, primarily observational studies, has yielded mixed results.

Multiple experts weighed in on the controversy in a previous report. Many point out the limitations of observational data, particularly when it comes to ruling out other factors that could affect the severity of COVID-19 infection. In addition, in a video report, JoAnn E. Manson, MD, DrPH, of Harvard Medical School in Boston, cited an observational study from three South Asian hospitals that found more severe COVID-19 patients had lower vitamin D levels, as well as other “compelling evidence” suggesting an association.

Dr. Frenkel-Morgenstern and colleagues studied data for 7,807 people, of whom 10.1% were COVID-19 positive. They assessed electronic health records for demographics, potential confounders, and outcomes between February 1 and April 30.

Participants positive for COVID-19 tended to be younger and were more likely to be men and live in a lower socioeconomic area, compared with the participants who were negative for COVID-19, in a univariate analysis.

Key findings

A higher proportion of COVID-19–positive patients had low plasma 25(OH)D concentrations, about 90% versus 85% of participants who were negative for COVID-19. The difference was statistically significant (P < .001). Furthermore, the increased likelihood for low vitamin D levels among those positive for COVID-19 held in a multivariate analysis that controlled for demographics and psychiatric and somatic disorders (adjusted odds ratio, 1.50). The difference remained statistically significant (P < .001).

The study also was noteworthy for what it did not find among participants with COVID-19. For example, the prevalence of dementia, cardiovascular disease, chronic lung disorders, and hypertension were significantly higher among the COVID-19 negative participants.

“Severe social contacts restrictions that were imposed on all the population and were even more emphasized in this highly vulnerable population” could explain these findings, the researchers noted.

“We assume that following the Israeli Ministry of Health instructions, patients with chronic medical conditions significantly reduced their social contacts” and thereby reduced their infection risk.

In contrast to previous reports, obesity was not a significant factor associated with increased likelihood for COVID-19 infection or hospitalization in the current study.

The researchers also linked low plasma 25(OH)D level to an increased likelihood of hospitalization for COVID-19 infection (crude OR, 2.09; P < .05).

After controlling for demographics and chronic disorders, the aOR decreased to 1.95 (P = .061) in a multivariate analysis. The only factor that remained statistically significant for hospitalization was age over 50 years (aOR, 2.71; P < .001).

Implications and future plans

The large number of participants and the “real world,” population-based design are strengths of the study. Considering potential confounders is another strength, the researchers noted. The retrospective database design was a limitation.

Going forward, Dr. Frenkel-Morgenstern and colleagues will “try to decipher the potential role of vitamin D in prevention and/or treatment of COVID-19” through three additional studies, she said. Also, they would like to conduct a meta-analysis to combine data from different countries to further explore the potential role of vitamin D in COVID-19.

“A compelling case”

“This is a strong study – large, adjusted for confounders, consistent with the biology and other clinical studies of vitamin D, infections, and COVID-19,” Wayne Jonas, MD, a practicing family physician and executive director of Samueli Integrative Health Programs, said in an interview.

Because the research was retrospective and observational, a causative link between vitamin D levels and COVID-19 risk cannot be interpreted from the findings. “That would need a prospective, randomized study,” said Dr. Jonas, who was not involved with the current study.

However, “the study makes a compelling case for possibly screening vitamin D levels for judging risk of COVID infection and hospitalization,” Dr. Jonas said, “and the compelling need for a large, randomized vitamin D supplement study to see if it can help prevent infection.”

“Given that vitamin D is largely safe, such a study could be done quickly and on healthy people with minimal risk for harm,” he added.
 

More confounders likely?

“I think the study is of interest,” Naveed Sattar, PhD,  professor of metabolic medicine at the University of Glasgow, who also was not affiliated with the research, said in an interview.

“Whilst the authors adjusted for some confounders, there is a strong potential for residual confounding,” said Dr. Sattar, a coauthor of a UK Biobank study that did not find an association between vitamin D stages and COVID-19 infection in multivariate models.

For example, Dr. Sattar said, “Robust adjustment for social class is important since both Vitamin D levels and COVID-19 severity are both strongly associated with social class.” Further, it remains unknown when and what time of year the vitamin D concentrations were measured in the current study.

“In the end, only a robust randomized trial can tell us whether vitamin D supplementation helps lessen COVID-19 severity,” Dr. Sattar added. “I am not hopeful we will find this is the case – but I am glad some such trials are [ongoing].”

Dr. Frenkel-Morgenstern received a COVID-19 Data Sciences Institute grant to support this work. Dr. Frenkel-Morgenstern, Dr. Jonas, and Dr. Sattar have disclosed no relevant financial relationships.

A secondary analysis of a major study of polypill therapy for hypertension found that patients who don’t reach blood pressure targets are less likely to have their medications adjusted if they’re on fixed-dose combination therapy.

However, hypertension patients on low-dose, triple-pill combination therapy are more likely to achieve blood pressure control than are those on usual care.

The secondary analysis of Triple Pill vs. Usual Care Management for Patients with Mild-to-Moderate Hypertension (TRIUMPH) was published online in JAMA Cardiology (2020 Jul 22. doi: 10.1001/jamacardio.2020.2739). The trial randomized 700 patients with hypertension in Sri Lanka to triple-pill fixed-dose combination (FDC) therapy or usual care during February 2016–May 2017, with follow-up ending in October 2017.

A greater proportion of FDC patients reached target BP by the end of the study compared with usual care, 70% vs. 55%. However, the study found that therapeutic inertia – the failure to intensify therapy in nonresponsive patients – was more common in the FDC group at 6- and 12-week follow-up: 87% vs. 64% and 90% vs. 65%, respectively; both differences were significant different at P < .001).

The once-daily FDC pill contained telmisartan 20 mg, amlodipine 2.5 mg; and chlorthalidone 12.5 mg.

“Using a triple low-dose combination blood-pressure pill reduced the need to uptitrate BP therapy as more patients are at target, but doctors were less likely to uptitrate with triple-pill therapy when it was needed,” lead author Nelson Wang, MD, a research fellow at the George Institute for Global Health in suburban Sydney, said in an interview.

“Overall, there were fewer treatment inertia episodes in the triple-pill group than in the usual care group, but this was driven by the fact that fewer triple-pill patients needed uptitration when coming to their follow-up visits,” Dr. Wang added.

The analysis found that clinicians who prescribed triple-pill FDC used 23 unique drug treatment regimens per 100 treated patients compared with 54 different regiments with usual care (P < .001). “There was a large simplification in care,” Dr. Wang said of the FDC approach.

Dr. Wang and colleagues called for greater efforts to address therapeutic inertia, particularly with FDC therapies, and suggested potential strategies consisting of patient education, incentives for appropriate treatment adjustments, and feedback mechanisms and reminders for physicians.

“There may also be a need for more dosage options with the FDC triple pill to allow physicians to intensify therapy without fear of overtreatment and adverse drug effects,” they wrote.

“The study showed there’s room for a both a population-based fixed-drug combination approach and a personalized approach to how we think about hypertension management with fixed-dose therapy,” she said in an interview. “It’s not a one-and-done situation.”

A secondary analysis of a major study of polypill therapy for hypertension found that patients who don’t reach blood pressure targets are less likely to have their medications adjusted if they’re on fixed-dose combination therapy.

However, hypertension patients on low-dose, triple-pill combination therapy are more likely to achieve blood pressure control than are those on usual care.

The secondary analysis of Triple Pill vs. Usual Care Management for Patients with Mild-to-Moderate Hypertension (TRIUMPH) was published online in JAMA Cardiology (2020 Jul 22. doi: 10.1001/jamacardio.2020.2739). The trial randomized 700 patients with hypertension in Sri Lanka to triple-pill fixed-dose combination (FDC) therapy or usual care during February 2016–May 2017, with follow-up ending in October 2017.

A greater proportion of FDC patients reached target BP by the end of the study compared with usual care, 70% vs. 55%. However, the study found that therapeutic inertia – the failure to intensify therapy in nonresponsive patients – was more common in the FDC group at 6- and 12-week follow-up: 87% vs. 64% and 90% vs. 65%, respectively; both differences were significant different at P < .001).

More than half of Hispanic adults would be afraid to go to a hospital for a possible heart attack or stroke because they might get infected with SARS-CoV-2, according to a new survey from the American Heart Association.

Compared with Hispanic respondents, 55% of whom said they feared COVID-19, significantly fewer Blacks (45%) and Whites (40%) would be scared to go to the hospital if they thought they were having a heart attack or stroke, the AHA said based on the survey of 2,050 adults, which was conducted May 29 to June 2, 2020, by the Harris Poll.

Hispanics also were significantly more likely to stay home if they thought they were experiencing a heart attack or stroke (41%), rather than risk getting infected at the hospital, than were Blacks (33%), who were significantly more likely than Whites (24%) to stay home, the AHA reported.

White respondents, on the other hand, were the most likely to believe (89%) that a hospital would give them the same quality of care provided to everyone else. Hispanics and Blacks had significantly lower rates, at 78% and 74%, respectively, the AHA noted.

These findings are “yet another challenge for Black and Hispanic communities, who are more likely to have underlying health conditions such as cardiovascular disease and diabetes and dying of COVID-19 at disproportionately high rates,” Rafael Ortiz, MD, American Heart Association volunteer medical expert and chief of neuro-endovascular surgery at Lenox Hill Hospital, New York, said in the AHA statement.

The survey was performed in conjunction with the AHA’s “Don’t Die of Doubt” campaign, which “reminds Americans, especially in Hispanic and Black communities, that the hospital remains the safest place to be if experiencing symptoms of a heart attack or a stroke.”

Among all the survey respondents, 57% said they would feel better if hospitals treated COVID-19 patients in a separate area. A number of other possible precautions ranked lower in helping them feel better:

• Screen all visitors, patients, and staff for COVID-19 symptoms when they enter the hospital: 39%.
• Require all patients, visitors, and staff to wear masks: 30%.
• Put increased cleaning protocols in place to disinfect multiple times per day: 23%.
• “Nothing would make me feel comfortable”: 6%.

Despite all the concerns about the risk of coronavirus infection, however, most Americans (77%) still believe that hospitals are the safest place to be in the event of a medical emergency, and 84% said that hospitals are prepared to safely treat emergencies that are not related to the pandemic, the AHA reported.

“Health care professionals know what to do even when things seem chaotic, and emergency departments have made plans behind the scenes to keep patients and healthcare workers safe even during a pandemic,” Dr. Ortiz pointed out.

Further refinement of data from patients hospitalized worldwide for COVID-19 disease showed a 12% prevalence rate of patients with diabetes in this population and a 17% prevalence rate for hypertension.

These are lower rates than previously reported for COVID-19 patients with either of these two comorbidities, yet the findings still document important epidemiologic links between diabetes, hypertension, and COVID-19, said the study’s authors.

A meta-analysis of data from 15,794 patients hospitalized because of COVID-19 disease that was drawn from 65 carefully curated reports published from December 1, 2019, to April 6, 2020, also showed that, among the hospitalized COVID-19 patients with diabetes (either type 1 or type 2), the rate of patients who required ICU admission was 96% higher than among those without diabetes and mortality was 2.78-fold higher, both statistically significant differences.

The rate of ICU admissions among those hospitalized with COVID-19 who also had hypertension was 2.95-fold above those without hypertension, and mortality was 2.39-fold higher, also statistically significant differences, reported a team of researchers in the recently published report.

The new meta-analysis was notable for the extra effort investigators employed to eliminate duplicated patients from their database of COVID-19 patients included in various published reports, a potential source of bias that likely introduced errors into prior meta-analyses that used similar data. “We found an overwhelming proportion of studies at high risk of data repetition,” the report said. Virtually all of the included studies were retrospective case studies, nearly two-thirds had data from a single center, and 71% of the studies included only patients in China.

“We developed a method to identify reports that had a high risk for repetitions” of included patients, said Fady Hannah-Shmouni, MD, a senior author of the study. “We also used methods to minimize bias, we excluded certain patients populations, and we applied a uniform definition of COVID-19 disease severity,” specifically patients who died or needed ICU admission, because the definitions used originally by many of the reports were very heterogeneous, said Dr. Hannah-Shmouni, principal investigator for Endocrine, Genetics, and Hypertension at the National Institute of Child Health and Human Development.

Despite the effort to eliminate case duplications, the analysis remains subject to additional confounders, in part because of a lack of comprehensive patient information on factors such as smoking, body mass index, socioeconomic status, and the specific type of diabetes or hypertension a patient had. “Even with these limitations, we were able to show that the prevalence of hypertension and diabetes is elevated in patients with COVID-19, that patients with diabetes have increased risk for both death and ICU admissions, and that there is the potential for reverse causality in the reporting of hypertension as a risk factor for COVID-19,” Dr. Hannah-Shmouni said in an interview. “We believe the explosion of data that associated hypertension and COVID-19 may be partially the result of reverse causality.”

One possible example of this reverse causality is the overlap between hypertension and age as potential risk factors for COVID-19 disease or increased infection severity. People “older than 80 frequently develop severe disease if infected with the novel coronavirus, and 80% of people older than 80 have hypertension, so it’s not surprising that hypertension is highly prevalent among hospitalized COVID-19 patients,” but this “does not imply a causal relationship between hypertension and severe COVID-19; the risk of hypertension probably depends on older age,” noted Ernesto L. Schiffrin, MD, a coauthor of the study, as well as professor of medicine at McGill University and director of the Hypertension and Vascular Research Unit at the Lady Davis Institute for Medical Research, both in Montreal. “My current opinion, on the basis of the totality of data, is that hypertension does not worsen [COVID-19] outcomes, but patients who are elderly, obese, diabetic, or immunocompromised are susceptible to more severe COVID-19 and worse outcomes,” said Dr. Schiffrin in an interview.

The new findings show “there is certainly an interplay between the virus, diabetes, and hypertension and other risk factors,” and while still limited by biases, the new findings “get closer” to correctly estimating the COVID-19 risks associated with these comorbidities,” Dr. Hannah-Shmouni said.

The connections identified between COVID-19, diabetes, and hypertension mean that patients with these chronic diseases should receive education about their COVID-19 risks and should have adequate access to the drugs and supplies they need to control blood pressure and hyperglycemia. Patients with diabetes also need to be current on vaccinations to reduce their risk for pneumonia. And recognition of the heightened COVID-19 risk for people with these comorbidities is important among people who work in relevant government agencies, health care workers, and patient advocacy groups, he added.

The study received no commercial funding. Dr. Hannah-Shmouni and Dr. Schiffrin had no disclosures.

As if the management of patients with severe COVID-19 infections is not complicated enough, an estimated 50%-60% of patients admitted to an ICU with the disease will have some form of cardiovascular involvement, which further increases their already high risk for morbidity and mortality.

Multimodality cardiovascular imaging, chosen wisely, can both help to direct management of cardiovascular complications associated with COVID-19 and lessen risk of exposure of health care workers to SARS-CoV-2, said members of an expert panel from the American College of Cardiology Cardiovascular Imaging Leadership Council.

“When we face a patient with known or suspected COVID-19, it’s not like any other disease because we face potential exposure risk to personnel doing imaging studies and also to other patients,” corresponding author Marcelo F. Di Carli, MD, of Brigham and Women’s Hospital Boston said in an interview.

“Any imaging study that is being considered should be performed only if we think it will help us make a change in the way that we’re going to treat that particular patient. This is true for imaging in any disease – why would you do an imaging study that will make no difference in treatment? – but the stakes are even higher in COVID-19,” he said.

The panel’s recommendations for cardiovascular imaging in patients with COVID-19 are outlined in a guidance document published online in the Journal of the American College of Cardiology.

The guidance begins by highlighting the importance of diagnostic testing for COVID-19 infection and the use of universal precautions for health care personnel performing imaging studies, as well as disinfection of imaging equipment and rooms after each use.

Circulating biomarkers that measure end-organ stress or injury, inflammation, hypoperfusion, and activation of thrombosis/hemostasis pathways may be prognostically useful, but “almost none of the widely measured biomarkers represent a specific trigger for imaging outside of that supported by clinical judgment,” the guidance states.

In contrast, low to moderate, nonrising concentrations of markers for myocardial stress, such as B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP), or of myocardial injury, such as cardiac troponins (cTn), may be helpful for excluding the need for imaging.

“Importantly, clinicians should be aware that most patients with abnormal BNP/NT-proBNP or cTn do not have acute heart failure or myocardial infarction; and rise in concentration of either class of biomarker presumably reflects complex processes including direct myocardial stress/injury related to systemic illness,” the panel members wrote.
 

Oldies but goodies

“One thing that we found out in our review of the literature and in our experiences in our own work settings is that cardiac ultrasound plays a huge role in this disease – like in any disease – but this one in particular,” Dr. Di Carli said. “One of the most feared complications in COVID-19 leads to inflammation of the heart muscle, which then leads to heart dysfunction. And of course cardiac ultrasound, because of its portability, can be performed at bedside to help clinicians ascertain an abnormality in the heart.”

Cardiac CT is also extremely helpful for determining whether patients with ECG findings suggestive of infarction have suffered an actual thrombotic event.

“These patients may best be served by a noninvasive study as compared to an invasive coronary angiogram,” he said.
 

Clinical scenarios

Cardiologists may be called in to consult on the evaluation of possible cardiogenic components of pulmonary abnormalities in patients who present with dyspnea and chest x-rays showing airspace or interstitial infiltrates suggestive of pneumonia, the authors noted.

“Clinicians will rely on history, physical exam, ECG [electrocardiogram] and biomarkers, and recent cardiac imaging tests if available. Underlying cardiac history including [coronary artery disease], cardiomyopathy, heart failure, and arrhythmia should be sought, and frequent contributors to decompensation should be eliminated,” they wrote.

For patients with suspected cardiac injury, either point-of-care ultrasound or limited echocardiography can be used for the initial evaluation, with additional, more advanced technologies called into play for specific clinical scenarios outlined in the guidance.

For example, the guidance recommends that patients with chest pain and abnormal ECG readings with clinical concern for ST-elevation acute coronary syndrome or high clinical risk for in-hospital mortality from conditions such as cardiogenic shock, dynamic ST-segment changes, or left ventricular ejection fraction less than 40% thought to be caused by non–ST-elevation myocardial infarction be referred for emergent coronary angiography and reperfusion.

In contrast, in patients with chest pain and abnormal ECG but equivocal symptoms, atypical or equivocal ECG abnormalities, or late presentations, point-of-care ultrasound or limited echocardiogram could be used to look for regional wall motion abnormalities and left ventricular ejection fraction, whereas in patients with chest pain and ST-elevation without clear evidence of ST-elevation myocardial infarction, coronary CT angiography can help to rule out ACS and point to alternate diagnoses, the authors said.

The guidance also offers recommendations for imaging in patients with hemodynamic instability (shock or hypotension), patients with new left ventricular dysfunction in the absence of shock or hypotension, and patients with subacute and chronic-phase disease.

Development of the guidance document was supported by the ACC. Dr. Di Carli disclosed institutional grant support from Gilead Sciences and Spectrum Dynamics, and consulting income from Janssen and Bayer.

As if the management of patients with severe COVID-19 infections is not complicated enough, an estimated 50%-60% of patients admitted to an ICU with the disease will have some form of cardiovascular involvement, which further increases their already high risk for morbidity and mortality.

Multimodality cardiovascular imaging, chosen wisely, can both help to direct management of cardiovascular complications associated with COVID-19 and lessen risk of exposure of health care workers to SARS-CoV-2, said members of an expert panel from the American College of Cardiology Cardiovascular Imaging Leadership Council.

“When we face a patient with known or suspected COVID-19, it’s not like any other disease because we face potential exposure risk to personnel doing imaging studies and also to other patients,” corresponding author Marcelo F. Di Carli, MD, of Brigham and Women’s Hospital Boston said in an interview.

“Any imaging study that is being considered should be performed only if we think it will help us make a change in the way that we’re going to treat that particular patient. This is true for imaging in any disease – why would you do an imaging study that will make no difference in treatment? – but the stakes are even higher in COVID-19,” he said.

In elderly or low-weight patients with acute coronary syndrome (ACS), a reduced dose of prasugrel relative to a full-dose of ticagrelor is associated with lower numerical rates of ischemic events and bleeding events, according to a prespecified substudy of the ISAR-REACT 5 trial.

“The present study provides the strongest support for reduced-dose prasugrel as the standard for elderly and low-weight patients with ACS undergoing an invasive treatment strategy,” according to the senior author, Adnan Kastrati, MD, professor of cardiology and head of the Catheterization Laboratory at Deutsches Herzzentrum, Technical University of Munich.

The main results of ISAR-REACT 5, an open-label, head-to-head comparison of prasugrel and ticagrelor in patients with ACS, showed that the risk of the composite primary endpoint of death, myocardial infarction, or stroke 1 year after randomization was significantly higher for those on ticagrelor than prasugrel (hazard ratio, 1.39; P = .006). The bleeding risk on ticagrelor was also higher but not significantly different (5.4% vs. 4.8%; P = .46) (Schüpke S et al. N Engl J Med. 2019 Oct;381:1524-34).

In this substudy newly published in Annals of Internal Medicine, outcomes were compared in the 1,099 patients who were 75 years or older or weighed less than 60 kg. In this group, unlike those younger or weighing more, patients were randomized to receive a reduced maintenance dose of 5 mg of once-daily prasugrel (rather than 10 mg) or full dose ticagrelor (90 mg twice daily).

At 1 year, the low-dose prasugrel strategy relative to ticagrelor was associated with a lower rate of events (12.7% vs. 14.6%) and a lower rate of bleeding (8.1% vs. 10.6%), defined as Bleeding Academic Research Consortium (BARC) type 3-5 events.

Neither the 18% reduction for the efficacy endpoint (HR, 0.82; 95% CI 0.60-1.14) nor the 28% reduction in the bleeding endpoint (HR, 0.72; 95% CI 0.46-1.12) reached significance, but Dr. Kastrati reported that there was a significant “treatment effect-by-study-group interaction” for BARC 1-5 bleeding (P = .004) favoring prasugrel. This supports low-dose prasugrel as a strategy to prevent the excess bleeding risk previously observed with the standard 10-mg dose of prasugrel.

In other words, a reduced dose of prasugrel, compared with the standard dose of ticagrelor, in low-weight and elderly patients “is associated with maintained anti-ischemic efficacy while protecting these patients against the excess risk of bleeding,” he and his coinvestigators concluded.

Low-weight and older patients represented 27% of those enrolled in ISAR-REACT 5. When compared to the study population as a whole, the risk for both ischemic and bleeding events was at least twice as high, the authors of an accompanying editorial observed. They praised this effort to refine the optimal antiplatelet regimen in a very-high-risk ACS population.

“The current analysis suggests that the prasugrel dose reduction regimen for elderly or underweight patients with ACS is effective and safe,” according to the editorial coauthors, David Conen, MD, and P.J. Devereaux, MD, PhD, who are affiliated with the Population Health Research Institute, Hamilton, Ontario.

This substudy was underpowered to show superiority for the efficacy and safety outcomes in elderly and low-weight ACS patients, which makes these results “hypothesis generating,” but the authors believe that they provide the best available evidence for selecting antiplatelet therapy in this challenging subgroup. Although the exclusion of patients at very high risk of bleeding from ISAR-REACT 5 suggest findings might not be relevant to all elderly and low-weight individuals, the investigators believe the data do inform clinical practice.

“Our study is the first head-to-head randomized comparison of the reduced dose of prasugrel against standard dose of ticagrelor in elderly and low-weight patients,” said Dr. Kastrati in an interview. “Specifically designed studies for this subset of patients are very unlikely to be conducted in the future.”

Dr. Kastrati reported no potential conflicts of interest relevant to this study.

Young adult smokers who stop smoking in the first year after an initial myocardial infarction are far less likely to die over the next 10 years than their peers who continue to smoke. Yet nearly two-thirds keep smoking after the event, according to new data from the Partners YOUNG-MI Registry.

“Smoking is one of the most common risk factors for developing an MI at a young age. ... This reinforces the need to have more young individuals avoid, or quit, the use of tobacco,” Ron Blankstein, MD, Brigham and Women’s Hospital and Harvard Medical School, Boston, said in an interview.

Yet, the finding that 62% of young adults continue to smoke 1 year after MI points to an “enormous need for better smoking cessation efforts following a heart attack,” he said.
 

“Powerful” message for clinicians

“This study joins an incredibly powerful body of evidence that says if you quit smoking, you’re going to live longer,” said Michael Fiore, MD, MPH, MBA, director of the University of Wisconsin Center for Tobacco Research and Intervention, Madison, who wasn’t involved in the study.

“As physicians, there is nothing we can do that will have a greater impact for our patients than quitting smoking. The study is a powerful call for clinicians to intervene with their patients that smoke – both if you have an MI or if you don’t,” Dr. Fiore told this news organization.

The study involved 2,072 individuals 50 years or younger (median age, 45 years; 81% male) who were hospitalized for an initial MI at two large academic medical centers in Boston. Of these, 33.9% were never-smokers, 13.6% were former smokers, and 52.5% were smokers at the time of their MI.

During a median follow-up of 10.2 years, those who quit smoking had a significantly lower rate of death from any cause (unadjusted hazard ratio, 0.35; 95% confidence interval, 0.19-0.63; P < .001) and a cardiovascular cause (HR, 0.29; 95% CI, 0.11-0.79; P = .02), relative to those who continued to smoke.

The results remained statistically significant in a propensity-matched analysis for both all-cause (HR, 0.30; 95% CI, 0.16-0.56; P < .001) and CV mortality (HR, 0.19; 95% CI, 0.06-0.56; P = .003).

“Although patients who quit smoking were similar to those who continued to smoke with respect to their baseline characteristics, smoking cessation was associated with an approximate 70%-80% reduction in all-cause and CV mortality,” the authors note in their article, published online July 8 in JAMA Network Open.

They say it’s also noteworthy that long-term death rates of never-smokers and former smokers who quit before the MI were nearly identical.

‘A failure of our health care system’

The bottom line, said Dr. Blankstein, is that it is “never too late to quit, and those who experience an MI should do so right away. Our health care system must help promote such efforts, as there is immense room for improvement.”

Dr. Fiore said: “When I see an article like this, it just reminds me that, if you’re really thinking about staying healthy, there is nothing better you can do to improve the quality and longevity of your life than quitting smoking.”

The observation that many patients continue to smoke after MI is a “failure of our health care system, and it’s an individual failure in that these individuals are not able to overcome their powerful nicotine dependence. It’s an unfortunate occurrence that’s resulting in unnecessary deaths,” said Dr. Fiore.

There is no “magic bullet” to overcome nicotine addiction, but there are approved treatments that can “substantially boost quit rates,” he noted.

The two most effective smoking-cessation treatments are varenicline (Chantix) and combination nicotine replacement therapy, a patch combined ideally with nicotine mini lozenges, particularly when combined with some brief counseling, said Fiore.

He encourages cardiologists to get their patients to commit to quitting and then link them to resources such as 1-800-QUIT-NOW or SmokeFree.gov.

Funding for the study was provided by grants from the National Heart, Lung, and Blood Institute. Dr. Blankstein reported receiving research support from Amgen and Astellas. Dr. Fiore had no relevant disclosures.

“Although patients who quit smoking were similar to those who continued to smoke with respect to their baseline characteristics, smoking cessation was associated with an approximate 70%-80% reduction in all-cause and CV mortality,” the authors note in their article, published online July 8 in JAMA Network Open.

They say it’s also noteworthy that long-term death rates of never-smokers and former smokers who quit before the MI were nearly identical.

‘A failure of our health care system’

The bottom line, said Dr. Blankstein, is that it is “never too late to quit, and those who experience an MI should do so right away. Our health care system must help promote such efforts, as there is immense room for improvement.”

Dr. Fiore said: “When I see an article like this, it just reminds me that, if you’re really thinking about staying healthy, there is nothing better you can do to improve the quality and longevity of your life than quitting smoking.”

The observation that many patients continue to smoke after MI is a “failure of our health care system, and it’s an individual failure in that these individuals are not able to overcome their powerful nicotine dependence. It’s an unfortunate occurrence that’s resulting in unnecessary deaths,” said Dr. Fiore.

There is no “magic bullet” to overcome nicotine addiction, but there are approved treatments that can “substantially boost quit rates,” he noted.

The two most effective smoking-cessation treatments are varenicline (Chantix) and combination nicotine replacement therapy, a patch combined ideally with nicotine mini lozenges, particularly when combined with some brief counseling, said Fiore.

He encourages cardiologists to get their patients to commit to quitting and then link them to resources such as 1-800-QUIT-NOW or SmokeFree.gov.

Funding for the study was provided by grants from the National Heart, Lung, and Blood Institute. Dr. Blankstein reported receiving research support from Amgen and Astellas. Dr. Fiore had no relevant disclosures.

Young adult smokers who stop smoking in the first year after an initial myocardial infarction are far less likely to die over the next 10 years than their peers who continue to smoke. Yet nearly two-thirds keep smoking after the event, according to new data from the Partners YOUNG-MI Registry.

“Smoking is one of the most common risk factors for developing an MI at a young age. ... This reinforces the need to have more young individuals avoid, or quit, the use of tobacco,” Ron Blankstein, MD, Brigham and Women’s Hospital and Harvard Medical School, Boston, said in an interview.

Yet, the finding that 62% of young adults continue to smoke 1 year after MI points to an “enormous need for better smoking cessation efforts following a heart attack,” he said.
 

“Powerful” message for clinicians

“This study joins an incredibly powerful body of evidence that says if you quit smoking, you’re going to live longer,” said Michael Fiore, MD, MPH, MBA, director of the University of Wisconsin Center for Tobacco Research and Intervention, Madison, who wasn’t involved in the study.

“As physicians, there is nothing we can do that will have a greater impact for our patients than quitting smoking. The study is a powerful call for clinicians to intervene with their patients that smoke – both if you have an MI or if you don’t,” Dr. Fiore told this news organization.

The study involved 2,072 individuals 50 years or younger (median age, 45 years; 81% male) who were hospitalized for an initial MI at two large academic medical centers in Boston. Of these, 33.9% were never-smokers, 13.6% were former smokers, and 52.5% were smokers at the time of their MI.

During a median follow-up of 10.2 years, those who quit smoking had a significantly lower rate of death from any cause (unadjusted hazard ratio, 0.35; 95% confidence interval, 0.19-0.63; P < .001) and a cardiovascular cause (HR, 0.29; 95% CI, 0.11-0.79; P = .02), relative to those who continued to smoke.

The first order of business in the long-awaited, recently released Centers for Medicare & Medicaid Services (CMS) proposed national coverage decision (NCD) for transcatheter mitral valve repair (TMVR) was to get rid of its familiar moniker.

The document tosses the term TMVR in favor of transcatheter edge-to-edge repair (TEER) “to more precisely define the treatment addressed in this NCD” and differentiate it from other therapies that repair or replace the mitral valve.

(In an off-the-cuff Twitter poll launched right after the CMS document’s release, 80.3% of respondents answered that they “hate” the new acronym and the remainder said they “love” it; those two were the poll’s only choices.)

The NCD proposal goes on to say that CMS coverage of TEER would expand to include treatment of symptomatic moderate-to-severe or severe functional mitral regurgitation (MR) when used with maximally tolerated guideline-directed medical therapy.

The proposed NCD has been expected since March 2019 when the US Food and Drug Administration (FDA) approved the MitraClip (Abbott Vascular) for secondary functional MR. Medicare has covered MitraClip for primary degenerative MR since 2014.

Abbott announced in October 2019 that it would ramp up production of the MitraClip, which is currently the only FDA-approved TEER device.

Further specifications

Even as the new proposed NCD would add CMS coverage for functional MR, it would also decline a coverage statement for degenerative MR. Instead, it proposes to leave such coverage decisions to local Medical Administrative Contractors (MACs), given a relatively low incidence of clip intervention for degenerative MR. Less than 1% of the Medicare population undergo TEER of the mitral valve for that indication, the document says.

“The MACs are structured to be able to take into account local patient, physician, and institutional factors, which are especially important when overall prevalence is very low.”

The proposal also emphasizes that patients undergoing such covered TEER procedures be “under the care of a heart failure physician specialist experienced in the care and treatment of mitral valve disease,» with additional care provided by a heart team that includes a cardiac surgeon, interventional cardiologist, interventional echocardiographer.

The new document is generally consistent with a Consensus Statement from the American Association for Thoracic Surgery, the American College of Cardiology (ACC), the Society for Cardiovascular Angiography and Interventions, and the Society of Thoracic Surgeons published in December 2019 and covered then by theheart.org / Medscape Cardiology.

In anticipation the CMS coverage proposal, the ACC earlier this year published a Focused Update of the 2017 Expert Consensus Decision Pathway on the Management of Mitral Regurgitation to reflect new evidence in the field, mainly the recent clinical trial data on functional MR from the MITRA-FR and COAPT trials.

“The proposed criteria are nicely guided by the multisociety consensus document, which sought to foster optimal patient outcomes while also maintaining access to TEER,” Sammy Elmariah, MD, MPH, from Massachusetts General Hospital in Boston, commented by email.

“These criteria, in conjunction with results of the COAPT trial, establish TEER as the standard of care for patients with symptomatic functional MR despite guideline-directed medical therapy who do not possess an alternative indication for cardiac surgery,” said Elmariah, a coauthor on both the Consensus Statement and the Focused Update.

The proposed NCD seems “reasonable,” cardiothoracic surgeon Michael J. Reardon, MD, Houston Methodist Hospital, said by email. But he thought there might be some objections to the requirement for TEER centers to have a surgery program with a minimum annual volume for mitral-valve surgeries.

The proposed NCD says a hospital must have “a surgical program that performs ≥25 total mitral valve surgical procedures for severe MR per year, of which at least 10 must be mitral valve repairs.”

“There is a very definite relationship between mitral valve surgery volume and surgical outcomes and between TEER volume and TEER outcomes, but no real relationship between mitral valve surgery volumes and TEER outcomes,” Reardon said. “A mitral valve surgery program is important, but how many cases do you need to be able to start and run a TEER program?”

Edwards Lifesciences is currently testing its own device for TEER: the PASCAL transcatheter mitral valve repair system. Early findings from the company’s ongoing CLASP IID trial, a head-to-head comparison of Pascal and MitraClip, are expected in December 2023.

CMS is seeking comments on the proposed national coverage determination, and will render a final decision within 60 days of the end of the 30-day public comment period.

Elmariah discloses receiving research grants from the American Heart Association, the National Institutes of Health, Edwards Lifesciences, Svelte Medical, and Medtronic, and consulting fees from AstraZeneca. Reardon recently reported no relevant conflicts of interest.
