Heart Failure

The American College of Cardiology has issued an expert consensus clinical guidance document for the evaluation and management of adults with key cardiovascular consequences of COVID-19.

The document makes recommendations on how to evaluate and manage COVID-associated myocarditis and long COVID and gives advice on resumption of exercise following COVID-19 infection.

The clinical guidance was published online March 16 in the Journal of the American College of Cardiology.

“The best means to diagnose and treat myocarditis and long COVID following SARS-CoV-2 infection continues to evolve,” said Ty Gluckman, MD, MHA, cochair of the expert consensus decision pathway. “This document attempts to provide key recommendations for how to evaluate and manage adults with these conditions, including guidance for safe return to play for both competitive and noncompetitive athletes.”

The authors of the guidance note that COVID-19 can be associated with various abnormalities in cardiac testing and a wide range of cardiovascular complications. For some patients, cardiac symptoms such as chest pain, shortness of breath, fatigue, and palpitations persist, lasting months after the initial illness, and evidence of myocardial injury has also been observed in both symptomatic and asymptomatic individuals, as well as after receipt of the COVID-19 mRNA vaccine. 

“For clinicians treating these individuals, a growing number of questions exist related to evaluation and management of these conditions, as well as safe resumption of physical activity,” they say. This report is intended to provide practical guidance on these issues.
 

Myocarditis

The report states that myocarditis has been recognized as a rare but serious complication of SARS-CoV-2 infection as well as COVID-19 mRNA vaccination.

It defines myocarditis as: 1.cardiac symptoms such as chest pain, dyspnea, palpitations, or syncope; 2. elevated cardiac troponin; and 3. abnormal electrocardiographic, echocardiographic, cardiac MRI, and/or histopathologic findings on biopsy.

The document makes the following recommendations in regard to COVID-related myocarditis:

When there is increased suspicion for cardiac involvement with COVID-19, initial testing should consist of an ECG, measurement of cardiac troponin, and an echocardiogram. Cardiology consultation is recommended for those with a rising cardiac troponin and/or echocardiographic abnormalities. Cardiac MRI is recommended in hemodynamically stable patients with suspected myocarditis.

Hospitalization is recommended for patients with definite myocarditis, ideally at an advanced heart failure center. Patients with fulminant myocarditis should be managed at centers with an expertise in advanced heart failure, mechanical circulatory support, and other advanced therapies.

Patients with myocarditis and COVID-19 pneumonia (with an ongoing need for supplemental oxygen) should be treated with corticosteroids. For patients with suspected pericardial involvement, treatment with NSAIDs, colchicine, and/or prednisone is reasonable. Intravenous corticosteroids may be considered in those with suspected or confirmed COVID-19 myocarditis with hemodynamic compromise or MIS-A (multisystem inflammatory syndrome in adults). Empiric use of corticosteroids may also be considered in those with biopsy evidence of severe myocardial infiltrates or fulminant myocarditis, balanced against infection risk.

As appropriate, guideline-directed medical therapy for heart failure should be initiated and continued after discharge.

The document notes that myocarditis following COVID-19 mRNA vaccination is rare, with highest rates seen in young males after the second vaccine dose. As of May 22, 2021, the U.S. Vaccine Adverse Event Reporting System noted rates of 40.6 cases per million after the second vaccine dose among male individuals aged 12-29 years and 2.4 cases per million among male individuals aged 30 and older. Corresponding rates in female individuals were 4.2 and 1 cases per million, respectively.

But the report says that COVID-19 vaccination is associated with “a very favorable benefit-to-risk ratio” for all age and sex groups evaluated thus far.

In general, vaccine-associated myocarditis should be diagnosed, categorized, and treated in a manner analogous to myocarditis following SARS-CoV-2 infection, the guidance advises.
 

Long COVID

The document refers to long COVID as postacute sequelae of SARS-CoV-2 infection (PASC), and reports that this condition is experienced by up to 10%-30% of infected individuals. It is defined by a constellation of new, returning, or persistent health problems experienced by individuals 4 or more weeks after COVID-19 infection.

Although individuals with this condition may experience wide-ranging symptoms, the symptoms that draw increased attention to the cardiovascular system include tachycardia, exercise intolerance, chest pain, and shortness of breath.

Nicole Bhave, MD, cochair of the expert consensus decision pathway, says: “There appears to be a ‘downward spiral’ for long-COVID patients. Fatigue and decreased exercise capacity lead to diminished activity and bed rest, in turn leading to worsening symptoms and decreased quality of life.” She adds that “the writing committee recommends a basic cardiopulmonary evaluation performed up front to determine if further specialty care and formalized medical therapy is needed for these patients.”

The authors propose two terms to better understand potential etiologies for those with cardiovascular symptoms:

PASC-CVD, or PASC-cardiovascular disease, refers to a broad group of cardiovascular conditions (including myocarditis) that manifest at least 4 weeks after COVID-19 infection.

PASC-CVS, or PASC-cardiovascular syndrome, includes a wide range of cardiovascular symptoms without objective evidence of cardiovascular disease following standard diagnostic testing.

The document makes the following recommendations for the management of PASC-CVD and PASC-CVS.

For patients with cardiovascular symptoms and suspected PASC, the authors suggest that a reasonable initial testing approach includes basic laboratory testing, including cardiac troponin, an ECG, an echocardiogram, an ambulatory rhythm monitor, chest imaging, and/or pulmonary function tests.

Cardiology consultation is recommended for patients with PASC who have abnormal cardiac test results, known cardiovascular disease with new or worsening symptoms, documented cardiac complications during SARS-CoV-2 infection, and/or persistent cardiopulmonary symptoms that are not otherwise explained.

Recumbent or semirecumbent exercise (for example, rowing, swimming, or cycling) is recommended initially for PASC-CVS patients with tachycardia, exercise/orthostatic intolerance, and/or deconditioning, with transition to upright exercise as orthostatic intolerance improves. Exercise duration should also be short (5-10 minutes/day) initially, with gradual increases as functional capacity improves.

Salt and fluid loading represent nonpharmacologic interventions that may provide symptomatic relief for patients with tachycardia, palpitations, and/or orthostatic hypotension.

Beta-blockers, nondihydropyridine calcium-channel blockers, ivabradine, fludrocortisone, and midodrine may be used empirically as well.
 

Return to play for athletes

The authors note that concerns about possible cardiac injury after COVID-19 fueled early apprehension regarding the safety of competitive sports for athletes recovering from the infection.

But they say that subsequent data from large registries have demonstrated an overall low prevalence of clinical myocarditis, without a rise in the rate of adverse cardiac events. Based on this, updated guidance is provided with a practical, evidence-based framework to guide resumption of athletics and intense exercise training.

They make the following recommendations:

• For athletes recovering from COVID-19 with ongoing cardiopulmonary symptoms (chest pain, shortness of breath, palpitations, lightheadedness) or those requiring hospitalization with increased suspicion for cardiac involvement, further evaluation with triad testing – an ECG, measurement of cardiac troponin, and an echocardiogram – should be performed.
• For those with abnormal test results, further evaluation with cardiac MRI should be considered. Individuals diagnosed with clinical myocarditis should abstain from exercise for 3-6 months.
• Cardiac testing is not recommended for asymptomatic individuals following COVID-19 infection. Individuals should abstain from training for 3 days to ensure that symptoms do not develop.
• For those with mild or moderate noncardiopulmonary symptoms (fever, lethargy, muscle aches), training may resume after symptom resolution.
• For those with remote infection (≥3 months) without ongoing cardiopulmonary symptoms, a gradual increase in exercise is recommended without the need for cardiac testing.

Based on the low prevalence of myocarditis observed in competitive athletes with COVID-19, the authors note that these recommendations can be reasonably applied to high-school athletes (aged 14 and older) along with adult recreational exercise enthusiasts.

Future study is needed, however, to better understand how long cardiac abnormalities persist following COVID-19 infection and the role of exercise training in long COVID.

The authors conclude that the current guidance is intended to help clinicians understand not only when testing may be warranted, but also when it is not.

“Given that it reflects the current state of knowledge through early 2022, it is anticipated that recommendations will change over time as our understanding evolves,” they say.

The 2022 ACC Expert Consensus Decision Pathway on Cardiovascular Sequelae of COVID-19: Myocarditis, Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), and Return to Play will be discussed in a session at the American College of Cardiology’s annual scientific session meeting in Washington in April.

A year of high-intensity interval training seemed to benefit obese middle-aged adults at a high risk of heart failure, but omega-3 fatty acid supplementation didn’t have any effect on cardiac biomarkers measured in a small, single-center, prospective study.

“One year of HIIT training reduces adiposity but had no consistent effect on myocardial triglyceride content or visceral adiposity,” wrote lead author Christopher M. Hearon Jr., PhD, and colleagues in JACC: Heart Failure. “However, long-duration HIIT improves fitness and induces favorable cardiac remodeling.” Omega-3 supplementation, however, had “no independent or additive effect.” Dr. Hearon is an instructor of applied clinical research at University of Texas Southwestern Medical Center in Dallas.

Investigators there and at the Institute for Exercise and Environmental Medicine at Texas Health Presbyterian Hospital Dallas studied 80 patients aged 40-55 years classified as high risk for HF and obese, randomizing them to a year of high-intensity interval training (HIIT) with supplementation of either 1.6 g omega-3 FA or placebo daily; or to a control group split between supplementation or placebo. Fifty-six patients completed the 1-year study, with a compliance rate of 90% in the HIIT group and 92% in those assigned omega-3 FA supplementation.

Carl J. “Chip” Lavie, MD, of the John Ochsner Heart and Vascular Institute in New Orleans, commented that, although the study was “extremely well done from an excellent research group,” it was limited by its small population and relatively short follow-up. Future research should evaluate HIIT and moderate exercise on clinical events over a longer term as well as different doses of omega-3 “There is tremendous potential for omega-3 in heart failure prevention and treatment.”
 

HIIT boosts exercise capacity, more

In the study, the HIIT group showed improvement in a number of cardiac markers: around a 22% improvement in exercise capacity as measured by absolute peak and relative peak oxygen uptake (VO₂), even without significant weight loss. They improved an average of 0.43 L/min (0.32-0.53; P < .0001) and 4.46 mL/kg per minute (3.18-5.56; ^P < .0001), respectively.

The researchers attributed the increase in peak VO₂ to an increase in peak cardiac output averaging 2.15 L/min (95% confidence interval, 0.90-3.39; P = .001) and stroke volume averaging 9.46 mL (95% CI, 0.65-18.27; P = .04). A year of exercise training also resulted in changes in cardiac remodeling, including increases in left ventricle mass and LV end diastolic volume, averaging 9.4 g (95% CI, 4.36-14.44; P < .001) and 12.33 mL (95% CI, 5.61-19.05; P < .001), respectively.  

The study also found that neither intervention had any appreciable impact on body weight, body mass index, body surface area or lean mass, or markers of arterial or local carotid stiffness. The exercise group had a modest decrease in fat mass, averaging 2.63 kg (95% CI,–4.81 to –0.46; P = .02), but without any effect from omega-3 supplementation.

The study acknowledged that high-dose omega-3 supplements have been found to lower triglyceride levels in people with severe hypertriglyceridemia, and hypothesized that HIIT alone or with omega-3 supplementation would improve fitness and biomarkers in people with stage A HF. “Contrary to our hypothesis, we found that one year of n-3FA [omega-3 FA] supplementation had no detectable effect on any parameter related to cardiopulmonary fitness, cardiovascular remodeling/stiffness, visceral adiposity, or myocardial triglyceride content,” Dr. Hearon and colleagues wrote.

The study “shows that obese middle-aged patients with heart failure with preserved ejection fraction [HFpEF] can markedly improve their fitness with HIIT and, generally, fitness is one of the strongest if not the strongest predictor of prognosis and survival,” said Dr. Lavie.

“Studies are needed on exercise that improves fitness in both HF with reduced ejection fraction and HFpEF, but especially HFpEF,” he said.

The study received funding from the American Heart Association Strategically Focused Research Network. Dr. Hearon and coauthors have no relevant disclosures. Dr. Lavie is a speaker and consultant for PAI Health, the Global Organization for EPA and DHA Omega-3s and DSM Nutritional Products.

The study received funding from the American Heart Association Strategically Focused Research Network. Dr. Hearon and coauthors have no relevant disclosures. Dr. Lavie is a speaker and consultant for PAI Health, the Global Organization for EPA and DHA Omega-3s and DSM Nutritional Products.
 

A year of high-intensity interval training seemed to benefit obese middle-aged adults at a high risk of heart failure, but omega-3 fatty acid supplementation didn’t have any effect on cardiac biomarkers measured in a small, single-center, prospective study.

“One year of HIIT training reduces adiposity but had no consistent effect on myocardial triglyceride content or visceral adiposity,” wrote lead author Christopher M. Hearon Jr., PhD, and colleagues in JACC: Heart Failure. “However, long-duration HIIT improves fitness and induces favorable cardiac remodeling.” Omega-3 supplementation, however, had “no independent or additive effect.” Dr. Hearon is an instructor of applied clinical research at University of Texas Southwestern Medical Center in Dallas.

Investigators there and at the Institute for Exercise and Environmental Medicine at Texas Health Presbyterian Hospital Dallas studied 80 patients aged 40-55 years classified as high risk for HF and obese, randomizing them to a year of high-intensity interval training (HIIT) with supplementation of either 1.6 g omega-3 FA or placebo daily; or to a control group split between supplementation or placebo. Fifty-six patients completed the 1-year study, with a compliance rate of 90% in the HIIT group and 92% in those assigned omega-3 FA supplementation.

Carl J. “Chip” Lavie, MD, of the John Ochsner Heart and Vascular Institute in New Orleans, commented that, although the study was “extremely well done from an excellent research group,” it was limited by its small population and relatively short follow-up. Future research should evaluate HIIT and moderate exercise on clinical events over a longer term as well as different doses of omega-3 “There is tremendous potential for omega-3 in heart failure prevention and treatment.”
 

HIIT boosts exercise capacity, more

In the study, the HIIT group showed improvement in a number of cardiac markers: around a 22% improvement in exercise capacity as measured by absolute peak and relative peak oxygen uptake (VO₂), even without significant weight loss. They improved an average of 0.43 L/min (0.32-0.53; P < .0001) and 4.46 mL/kg per minute (3.18-5.56; ^P < .0001), respectively.

The researchers attributed the increase in peak VO₂ to an increase in peak cardiac output averaging 2.15 L/min (95% confidence interval, 0.90-3.39; P = .001) and stroke volume averaging 9.46 mL (95% CI, 0.65-18.27; P = .04). A year of exercise training also resulted in changes in cardiac remodeling, including increases in left ventricle mass and LV end diastolic volume, averaging 9.4 g (95% CI, 4.36-14.44; P < .001) and 12.33 mL (95% CI, 5.61-19.05; P < .001), respectively.  

The study also found that neither intervention had any appreciable impact on body weight, body mass index, body surface area or lean mass, or markers of arterial or local carotid stiffness. The exercise group had a modest decrease in fat mass, averaging 2.63 kg (95% CI,–4.81 to –0.46; P = .02), but without any effect from omega-3 supplementation.

The study acknowledged that high-dose omega-3 supplements have been found to lower triglyceride levels in people with severe hypertriglyceridemia, and hypothesized that HIIT alone or with omega-3 supplementation would improve fitness and biomarkers in people with stage A HF. “Contrary to our hypothesis, we found that one year of n-3FA [omega-3 FA] supplementation had no detectable effect on any parameter related to cardiopulmonary fitness, cardiovascular remodeling/stiffness, visceral adiposity, or myocardial triglyceride content,” Dr. Hearon and colleagues wrote.

The study “shows that obese middle-aged patients with heart failure with preserved ejection fraction [HFpEF] can markedly improve their fitness with HIIT and, generally, fitness is one of the strongest if not the strongest predictor of prognosis and survival,” said Dr. Lavie.

“Studies are needed on exercise that improves fitness in both HF with reduced ejection fraction and HFpEF, but especially HFpEF,” he said.

Cancer significantly raises a patient’s risk for cardiovascular morbidity and mortality, particularly within the first year after diagnosis and irrespective of cancer type, according to a population-based study.

The retrospective analysis, which included data from more than 200,000 patients with cancer, found that a new cancer diagnosis significantly increased the risk of cardiovascular (CV) death (hazard ratio [HR], 1.33) as well as other CV events, including stroke (HR, 1.44), heart failure (HR, 1.62) and pulmonary embolism (HR, 3.43).

From the results, the researchers concluded that a “new cancer diagnosis is independently associated with a significantly increased risk for cardiovascular death and nonfatal morbidity regardless of cancer site.”

The findings were published in the Journal of the American College of Cardiology: CardioOncology (2022 Mar;4[1]:85-94).

Patients with cancer and cancer survivors are known to have an increased risk for heart failure, but evidence on the risk for other CV outcomes remains less clear. In addition, the authors noted, many cancer therapies – including chest irradiation and chemotherapy – can increase a person’s risk of incident CV disease during treatment and after, but data on the long-term CV risk among cancer survivors conflict.

D. Ian Paterson, MD, of the University of Alberta, Edmonton, and coauthors wanted to clarify how a new cancer diagnosis at various sites and stages might affect a person’s risk for fatal and nonfatal CV events over the long term.

The current analysis included data from 224,016 patients with a new cancer diagnosis identified from an administrative database of more than 4.5 million adults residing in Alberta. The researcher identified 73,360 CV deaths and 470,481 nonfatal CV events between April 2007 and December 2018.

Comparing CV events in those with and in those without cancer, the authors found that patients with cancer had a 33% increased risk for CV mortality over the 12-year study follow-up, after adjusting for sociodemographic data and comorbidities (HR, 1.33; 95% confidence interval [CI], 1.29-1.37). Patients with cancer also had an increased risk for stroke (HR, 1.44), heart failure (HR, 1.62) and pulmonary embolism (HR, 3.43), though not myocardial infarction (HR, 1.01; 95% CI, 0.97 – 1.05), compared to those without cancer.

The extent of the risk varied somewhat by cancer stage, time from diagnosis, and cancer type.

A new cancer diagnosis put patients at a significantly higher risk of CV mortality, heart failure, stroke, or pulmonary embolism, regardless of the cancer site, but the risk of CV events was highest for patients with genitourinary, gastrointestinal, thoracic, nervous system, and hematologic malignancies. These patients accounted for more than half of the cancer cohort and more than 70% of the incident CV burden.

Patients with more advanced cancer were at the highest risk for poor CV outcomes, but even those with very early-stage disease faced an elevated risk.

The risk for CV events was greatest in the first year following a cancer diagnosis for all outcomes (HRs, 1.24-8.36) but remained significantly elevated for CV death, heart failure, and pulmonary embolism a decade later.

Overall, the authors concluded that “patients with cancer constitute a high-risk population for CV disease” over the long term and suggested that those with cancer “may benefit from comanagement that includes cardiologists as well as stroke and thrombosis specialists.”

In an accompanying editorial, Hiroshi Ohtsu of Juntendo University in Tokyo, and colleagues concluded that the work “has remarkable strengths” and important clinical implications. However, they said that additional steps may be warranted before translating these findings to clinical practice.

For example, the study is limited by its retrospective population-based design and the lack of data on cancer therapy as well as on several patient factors, including ethnicity, smoking, and physical activity.

The study authors agreed, noting that future work should evaluate how cancer therapies and other potential contributors to poor CV outcomes influence patients’ risk.

“Such work would potentially lead to better prediction of CV risk for patients with cancer and survivors and improved prevention and treatment strategies,” they wrote.

The study was supported by a foundation grant from the Canadian Institutes of Health Research. The authors have disclosed no relevant financial relationships. The editorial was supported in part by funding to individual authors from the Japan Society for the Promotion of Science/Ministry of Education, Culture, Sports, Science and Technology, the Ministry of Health, Labour and Welfare, and the Agency for Medical Research and Development.

The genetically altered pig’s heart “worked like a rock star, beautifully functioning,” the surgeon who performed the pioneering Jan. 7 xenotransplant procedure said in a press statement on the death of the patient, David Bennett Sr.

“He wasn’t able to overcome what turned out to be devastating – the debilitation from his previous period of heart failure, which was extreme,” said Bartley P. Griffith, MD, clinical director of the cardiac xenotransplantation program at the University of Maryland, Baltimore.

University of Maryland Medical Center

Representatives of the institution aren’t offering many details on the cause of Mr. Bennett’s death on March 8, 60 days after his operation, but said they will elaborate when their findings are formally published. But their comments seem to downplay the unique nature of the implanted heart itself as a culprit and instead implicate the patient’s diminished overall clinical condition and what grew into an ongoing battle with infections.

The 57-year-old Bennett, bedridden with end-stage heart failure, judged a poor candidate for a ventricular assist device, and on extracorporeal membrane oxygenation (ECMO), reportedly was offered the extraordinary surgery after being turned down for a conventional transplant at several major centers.

“Until day 45 or 50, he was doing very well,” Muhammad M. Mohiuddin, MD, the xenotransplantation program’s scientific director, observed in the statement. But infections soon took advantage of his hobbled immune system.

Given his “preexisting condition and how frail his body was,” Dr. Mohiuddin said, “we were having difficulty maintaining a balance between his immunosuppression and controlling his infection.” Mr. Bennett went into multiple organ failure and “I think that resulted in his passing away.”


 

Beyond wildest dreams

The surgeons confidently framed Mr. Bennett’s experience as a milestone for heart xenotransplantation. “The demonstration that it was possible, beyond the wildest dreams of most people in the field, even, at this point – that we were able to take a genetically engineered organ and watch it function flawlessly for 9 weeks – is pretty positive in terms of the potential of this therapy,” Dr. Griffith said.

But enough questions linger that others were more circumspect, even as they praised the accomplishment. “There’s no question that this is a historic event,” Mandeep R. Mehra, MD, of Harvard Medical School, and director of the Center for Advanced Heart Disease at Brigham and Women’s Hospital, both in Boston, said in an interview.

Still, “I don’t think we should just conclude that it was the patient’s frailty or death from infection,” Dr. Mehra said. With so few details available, “I would be very careful in prematurely concluding that the problem did not reside with the heart but with the patient. We cannot be sure.”

For example, he noted, “6 to 8 weeks is right around the time when some cardiac complications, like accelerated forms of vasculopathy, could become evident.” Immune-mediated cardiac allograft vasculopathy is a common cause of heart transplant failure.

Or, “it could as easily have been the fact that immunosuppression was modified at 6 to 7 weeks in response to potential infection, which could have led to a cardiac compromise,” Dr. Mehra said. “We just don’t know.”

“It’s really important that this be reported in a scientifically accurate way, because we will all learn from this,” Lori J. West, MD, DPhil, said in an interview.

Little seems to be known for sure about the actual cause of death, “but the fact there was not hyperacute rejection is itself a big step forward. And we know, at least from the limited information we have, that it did not occur,” observed Dr. West, who directs the Alberta Transplant Institute, Edmonton, and the Canadian Donation and Transplantation Research Program. She is a professor of pediatrics with adjunct positions in the departments of surgery and microbiology/immunology.

Dr. West also sees Mr. Bennett’s struggle with infections and adjustments to his unique immunosuppressive regimen, at least as characterized by his care team, as in line with the experience of many heart transplant recipients facing the same threat.

“We already walk this tightrope with every transplant patient,” she said. Typically, they’re put on a somewhat standardized immunosuppressant regimen, “and then we modify it a bit, either increasing or decreasing it, depending on the posttransplant course.” The regimen can become especially intense in response to new signs of rejection, “and you know that that’s going to have an impact on susceptibility to all kinds of infections.”
 

Full circle

The porcine heart was protected along two fronts against assault from Mr. Bennett’s immune system and other inhospitable aspects of his physiology, either of which could also have been obstacles to success: Genetic modification (Revivicor) of the pig that provided the heart, and a singularly aggressive antirejection drug regimen for the patient.

The knockout of three genes targeting specific porcine cell-surface carbohydrates that provoke a strong human antibody response reportedly averted a hyperacute rejection response that would have caused the graft to fail almost immediately.

Other genetic manipulations, some using CRISPR technology, silenced genes encoded for porcine endogenous retroviruses. Others were aimed at controlling myocardial growth and stemming graft microangiopathy.  

Mr. Bennett himself was treated with powerful immunosuppressants, including an investigational anti-CD40 monoclonal antibody (KPL-404, Kiniksa Pharmaceuticals) that, according to UMSOM, inhibits a well-recognized pathway critical to B-cell proliferation, T-cell activation, and antibody production.

“I suspect the patient may not have had rejection, but unfortunately, that intense immunosuppression really set him up – even if he had been half that age – for a very difficult time,” David A. Baran, MD, a cardiologist from Sentara Advanced Heart Failure Center, Norfolk, Va., who studies transplant immunology, said in an interview.

“This is in some ways like the original heart transplant in 1967, when the ability to do the surgery evolved before understanding of the immunosuppression needed. Four or 5 years later, heart transplantation almost died out, before the development of better immunosuppressants like cyclosporine and later tacrolimus,” Dr. Baran said.

“The current age, when we use less immunosuppression than ever, is based on 30 years of progressive success,” he noted. This landmark xenotransplantation “basically turns back the clock to a time when the intensity of immunosuppression by definition had to be extremely high, because we really didn’t know what to expect.”
 

Emerging role of xeno-organs

Xenotransplantation has been touted as potential strategy for expanding the pool of organs available for transplantation. Mr. Bennett’s “breakthrough surgery” takes the world “one step closer to solving the organ shortage crisis,” his surgeon, Dr. Griffith, announced soon after the procedure. “There are simply not enough donor human hearts available to meet the long list of potential recipients.”

But it’s not the only proposed approach. Measures could be taken, for example, to make more efficient use of the human organs that become available, partly by opening the field to additional less-than-ideal hearts and loosening regulatory mandates for projected graft survival.

“Every year, more than two-thirds of donor organs in the United States are discarded. So it’s not actually that we don’t have enough organs, it’s that we don’t have enough organs that people are willing to take,” Dr. Baran said. Still, it’s important to pursue all promising avenues, and “the genetic manipulation pathway is remarkable.”

But “honestly, organs such as kidneys probably make the most sense” for early study of xenotransplantation from pigs, he said. “The waiting list for kidneys is also very long, but if the kidney graft were to fail, the patient wouldn’t die. It would allow us to work out the immunosuppression without putting patients’ lives at risk.”

Often overlooked in assessments of organ demand, Dr. West said, is that “a lot of patients who could benefit from a transplant will never even be listed for a transplant.” It’s not clear why; perhaps they have multiple comorbidities, live too far from a transplant center, “or they’re too big or too small. Even if there were unlimited organs, you could never meet the needs of people who could benefit from transplantation.”

So even if more available donor organs were used, she said, there would still be a gap that xenotransplantation could help fill. “I’m very much in favor of research that allows us to continue to try to find a pathway to xenotransplantation. I think it’s critically important.”

Unquestionably, “we now need to have a dialogue to entertain how a technology like this, using modern medicine with gene editing, is really going to be utilized,” Dr. Mehra said. The Bennett case “does open up the field, but it also raises caution.” There should be broad participation to move the field forward, “coordinated through either societies or nationally allocated advisory committees that oversee the movement of this technology, to the next step.”

Ideally, that next step “would be to do a safety clinical trial in the right patient,” he said. “And the right patient, by definition, would be one who does not have a life-prolonging option, either mechanical circulatory support or allograft transplantation. That would be the goal.”

Dr. Mehra has reported receiving payments to his institution from Abbott for consulting; consulting fees from Janssen, Mesoblast, Broadview Ventures, Natera, Paragonix, Moderna, and the Baim Institute for Clinical Research; and serving on a scientific advisory board NuPulseCV, Leviticus, and FineHeart. Dr. Baran disclosed consulting for Getinge and LivaNova; speaking for Pfizer; and serving on trial steering committees for CareDx and Procyrion, all unrelated to xenotransplantation. Dr. West has declared no relevant conflicts.

But it’s not the only proposed approach. Measures could be taken, for example, to make more efficient use of the human organs that become available, partly by opening the field to additional less-than-ideal hearts and loosening regulatory mandates for projected graft survival.

“Every year, more than two-thirds of donor organs in the United States are discarded. So it’s not actually that we don’t have enough organs, it’s that we don’t have enough organs that people are willing to take,” Dr. Baran said. Still, it’s important to pursue all promising avenues, and “the genetic manipulation pathway is remarkable.”

But “honestly, organs such as kidneys probably make the most sense” for early study of xenotransplantation from pigs, he said. “The waiting list for kidneys is also very long, but if the kidney graft were to fail, the patient wouldn’t die. It would allow us to work out the immunosuppression without putting patients’ lives at risk.”

Often overlooked in assessments of organ demand, Dr. West said, is that “a lot of patients who could benefit from a transplant will never even be listed for a transplant.” It’s not clear why; perhaps they have multiple comorbidities, live too far from a transplant center, “or they’re too big or too small. Even if there were unlimited organs, you could never meet the needs of people who could benefit from transplantation.”

So even if more available donor organs were used, she said, there would still be a gap that xenotransplantation could help fill. “I’m very much in favor of research that allows us to continue to try to find a pathway to xenotransplantation. I think it’s critically important.”

Unquestionably, “we now need to have a dialogue to entertain how a technology like this, using modern medicine with gene editing, is really going to be utilized,” Dr. Mehra said. The Bennett case “does open up the field, but it also raises caution.” There should be broad participation to move the field forward, “coordinated through either societies or nationally allocated advisory committees that oversee the movement of this technology, to the next step.”

Ideally, that next step “would be to do a safety clinical trial in the right patient,” he said. “And the right patient, by definition, would be one who does not have a life-prolonging option, either mechanical circulatory support or allograft transplantation. That would be the goal.”

Dr. Mehra has reported receiving payments to his institution from Abbott for consulting; consulting fees from Janssen, Mesoblast, Broadview Ventures, Natera, Paragonix, Moderna, and the Baim Institute for Clinical Research; and serving on a scientific advisory board NuPulseCV, Leviticus, and FineHeart. Dr. Baran disclosed consulting for Getinge and LivaNova; speaking for Pfizer; and serving on trial steering committees for CareDx and Procyrion, all unrelated to xenotransplantation. Dr. West has declared no relevant conflicts.

The genetically altered pig’s heart “worked like a rock star, beautifully functioning,” the surgeon who performed the pioneering Jan. 7 xenotransplant procedure said in a press statement on the death of the patient, David Bennett Sr.

“He wasn’t able to overcome what turned out to be devastating – the debilitation from his previous period of heart failure, which was extreme,” said Bartley P. Griffith, MD, clinical director of the cardiac xenotransplantation program at the University of Maryland, Baltimore.

University of Maryland Medical Center

Representatives of the institution aren’t offering many details on the cause of Mr. Bennett’s death on March 8, 60 days after his operation, but said they will elaborate when their findings are formally published. But their comments seem to downplay the unique nature of the implanted heart itself as a culprit and instead implicate the patient’s diminished overall clinical condition and what grew into an ongoing battle with infections.

The 57-year-old Bennett, bedridden with end-stage heart failure, judged a poor candidate for a ventricular assist device, and on extracorporeal membrane oxygenation (ECMO), reportedly was offered the extraordinary surgery after being turned down for a conventional transplant at several major centers.

“Until day 45 or 50, he was doing very well,” Muhammad M. Mohiuddin, MD, the xenotransplantation program’s scientific director, observed in the statement. But infections soon took advantage of his hobbled immune system.

Given his “preexisting condition and how frail his body was,” Dr. Mohiuddin said, “we were having difficulty maintaining a balance between his immunosuppression and controlling his infection.” Mr. Bennett went into multiple organ failure and “I think that resulted in his passing away.”


 

Beyond wildest dreams

The surgeons confidently framed Mr. Bennett’s experience as a milestone for heart xenotransplantation. “The demonstration that it was possible, beyond the wildest dreams of most people in the field, even, at this point – that we were able to take a genetically engineered organ and watch it function flawlessly for 9 weeks – is pretty positive in terms of the potential of this therapy,” Dr. Griffith said.

But enough questions linger that others were more circumspect, even as they praised the accomplishment. “There’s no question that this is a historic event,” Mandeep R. Mehra, MD, of Harvard Medical School, and director of the Center for Advanced Heart Disease at Brigham and Women’s Hospital, both in Boston, said in an interview.

Still, “I don’t think we should just conclude that it was the patient’s frailty or death from infection,” Dr. Mehra said. With so few details available, “I would be very careful in prematurely concluding that the problem did not reside with the heart but with the patient. We cannot be sure.”

For example, he noted, “6 to 8 weeks is right around the time when some cardiac complications, like accelerated forms of vasculopathy, could become evident.” Immune-mediated cardiac allograft vasculopathy is a common cause of heart transplant failure.

Or, “it could as easily have been the fact that immunosuppression was modified at 6 to 7 weeks in response to potential infection, which could have led to a cardiac compromise,” Dr. Mehra said. “We just don’t know.”

“It’s really important that this be reported in a scientifically accurate way, because we will all learn from this,” Lori J. West, MD, DPhil, said in an interview.

Little seems to be known for sure about the actual cause of death, “but the fact there was not hyperacute rejection is itself a big step forward. And we know, at least from the limited information we have, that it did not occur,” observed Dr. West, who directs the Alberta Transplant Institute, Edmonton, and the Canadian Donation and Transplantation Research Program. She is a professor of pediatrics with adjunct positions in the departments of surgery and microbiology/immunology.

Dr. West also sees Mr. Bennett’s struggle with infections and adjustments to his unique immunosuppressive regimen, at least as characterized by his care team, as in line with the experience of many heart transplant recipients facing the same threat.

“We already walk this tightrope with every transplant patient,” she said. Typically, they’re put on a somewhat standardized immunosuppressant regimen, “and then we modify it a bit, either increasing or decreasing it, depending on the posttransplant course.” The regimen can become especially intense in response to new signs of rejection, “and you know that that’s going to have an impact on susceptibility to all kinds of infections.”
 

Full circle

The porcine heart was protected along two fronts against assault from Mr. Bennett’s immune system and other inhospitable aspects of his physiology, either of which could also have been obstacles to success: Genetic modification (Revivicor) of the pig that provided the heart, and a singularly aggressive antirejection drug regimen for the patient.

The knockout of three genes targeting specific porcine cell-surface carbohydrates that provoke a strong human antibody response reportedly averted a hyperacute rejection response that would have caused the graft to fail almost immediately.

Other genetic manipulations, some using CRISPR technology, silenced genes encoded for porcine endogenous retroviruses. Others were aimed at controlling myocardial growth and stemming graft microangiopathy.  

Mr. Bennett himself was treated with powerful immunosuppressants, including an investigational anti-CD40 monoclonal antibody (KPL-404, Kiniksa Pharmaceuticals) that, according to UMSOM, inhibits a well-recognized pathway critical to B-cell proliferation, T-cell activation, and antibody production.

“I suspect the patient may not have had rejection, but unfortunately, that intense immunosuppression really set him up – even if he had been half that age – for a very difficult time,” David A. Baran, MD, a cardiologist from Sentara Advanced Heart Failure Center, Norfolk, Va., who studies transplant immunology, said in an interview.

“This is in some ways like the original heart transplant in 1967, when the ability to do the surgery evolved before understanding of the immunosuppression needed. Four or 5 years later, heart transplantation almost died out, before the development of better immunosuppressants like cyclosporine and later tacrolimus,” Dr. Baran said.

“The current age, when we use less immunosuppression than ever, is based on 30 years of progressive success,” he noted. This landmark xenotransplantation “basically turns back the clock to a time when the intensity of immunosuppression by definition had to be extremely high, because we really didn’t know what to expect.”
 

Emerging role of xeno-organs

Xenotransplantation has been touted as potential strategy for expanding the pool of organs available for transplantation. Mr. Bennett’s “breakthrough surgery” takes the world “one step closer to solving the organ shortage crisis,” his surgeon, Dr. Griffith, announced soon after the procedure. “There are simply not enough donor human hearts available to meet the long list of potential recipients.”

More than 18 months after the Watchman FLX device was licensed by the Food and Drug Administration for closure of the left atrial appendage (LAA), a prospective analysis of registry data presented at CRT 2022, sponsored by MedStar Heart & Vascular Institute, supports its safely outside of the clinical trial setting.

The data, drawn from the LAA occlusion registry of the National Cardiovascular Data Registry, showed a mortality rate at 45 days of under 1.0%, which was consistent with the acceptably low rate of other adverse events, according to Samir R. Kapadia, MD, chair of cardiovascular medicine at the Cleveland Clinic.

Only 0.5% had a pericardial effusion within 45 days of LAA closure that required intervention. Of those without effusion, 95% had a leak of less than 3 mm and 82% had no leak at all, according to Dr. Kapadia.

Patients enrolled in this analysis, called SURPASS (Surveillance Post Approval Analysis Plan), had undergone left atrial closure with the device from August 2020 to September 2022. There were no exclusion criteria. Ultimately, 2 years of follow-up is planned.

With more than 16,000 patients enrolled, the data on 14,363 patients in this initial 45-day analysis represents “the largest number of Watchman FLX patients evaluated to date,” Dr. Kapadia reported.
 

Device implantation success 97.5%

The Watchman FLX, which is delivered to the left atrial appendage by a transcatheter approach, was deployed successfully in 97.5% of all 16,048 patients enrolled in the registry. In the 398 cases without successful deployment, the anatomy was not conducive in nearly 70%. Other reasons included failure to meet device-release criteria and change in patient condition.

The outcomes of interest at 45 days were ischemic strokes, systemic emboli, device-related thrombi, device embolization, and bleeding. The primary endpoints at 2 years will be strokes and thrombotic events.

For stroke, the incidence within 45 days was 0.39%. About 25% of the strokes were hemorrhagic and the remainder were ischemic. There was 1 systemic embolism (0.01%), 5 device embolizations (0.03%), and 30 device-related thrombotic events (0.24%). Major bleeding occurred in 508 patients (3.55%).

For context, Dr. Kapadia compared these results to those observed in the PINNACLE FLX trial, which was a nonrandomized but prospective study of the Watchman FLX published about 1 year ago. In PINNACLE FLX, the enrollment was open to patients indicated for oral anticoagulation but who had an appropriate rationale for seeking a nonpharmacological alternative.

Taken from different studies, the outcomes at 45 days should not be construed as a direct comparison, but the similarity of the results can be considered reassuring, according to Dr. Kapadia.

For the composite safety endpoint of all-cause death, ischemic stroke, systemic embolism, or implantation-related events requiring intervention, the rates in SURPASS (0.4%) and PINNACLE FLX (0.5%) were nearly identical. Device leak rates (82.0% vs. 82.8%), stroke rates (0.4% vs. 0.7%), and all-cause death rates (0.9% vs. 0.5%) were also similar.

The similarity of the SURPASS and PINNACLE FLX data provides another level of reassurance.

“The SURPASS registry confirms the safety of the Watchman Flex in the real-world experience when the device is being used by many different operators in a large patient population,” Dr. Kapadia said in an interview.

In “appropriately selected patients,” the SURPASS data confirm that the Watchman FLX device “provides a safe and effective treatment option,” he added.

Relative to the PINNACLE FLX study, which enrolled 400 patients, it is noteworthy that the median age in SURPASS was older (76 vs. 73.8 years), a potential disadvantage in demonstrating comparable safety. The proportion of non-White patients was similar (6.7% vs. 6.3%). SURPASS had a higher proportion of women (40% vs. 35.5%).

The SURPASS data are credible, according to Vivek Y. Reddy, MD, director of cardiac arrhythmia services, Mount Sinai Health System, New York.

“While there are certainly limitations to registry data, I do feel pretty confident that these procedural complication and success rates [in SURPASS] do indeed reflect reality,” said Dr. Reddy, who was a coauthor of the PINNACLE FLX trial. In general, the SURPASS data “mirror most of our clinical experiences in routine clinical practice.”

With these registry data backing up multiple clinical studies, Dr. Reddy concluded, “I do believe that it is fair to say that Watchman-FLX implantation is a quite safe procedure.”

Dr. Kapadia reported no potential conflicts of interest. Dr. Reddy reported a financial relationship with Boston Scientific.

Although the Sentinel cerebral embolism protection (CEP) device may not significantly reduce the overall stroke rate in patients after they’ve had transcatheter aortic valve replacement (TAVR), the device may improve survival and reduce the severity of procedure-related stroke, a retrospective database study reported.

Investigators led by Samir R. Kapadia, MD, chair of cardiovascular medicine at the Cleveland Clinic, analyzed outcomes of 136,382 patients in the Nationwide Readmissions Database who had TAVR in 2018-2019. The dataset included 10,201 people who received the Sentinel CEP device during TAVR.

The proportion of patients who had a stroke after TAVR was similar in both groups – 1.85% (189) in the CEP group and 1.94% (1,447) in the CEP nonusers – but, as Dr. Kapadia pointed out, the stroke outcomes between the two groups were noticeably different.

“Interestingly enough, what we found was that the people with the CEPs who had a stroke had half the mortality, and they were going home at a significantly higher rate, than the people who had a stroke and didn’t have CEPs,” Dr. Kapadia said in an interview. A previous registry study of 276,316 TAVR patients reported the overall rate of post-TAVR stroke declined from 2.75% to 2.3% over an 8-year period. The CEP device, approved in December 2017, had been available in the last 2 years of that study.

In the current retrospective database study, CEP patients went home after their post-TAVR strokes at a rate of 28.2%, compared with 19.9% for those who didn’t have CEP (P = .011). The in-hospital death rates were 6.3% and 11.8% for the respective groups (P = .023), and the 30-day readmission rates were 15.9% and 16.8% (P = .91). “The readmission rate is similar, but if you survive you get admitted,” Dr. Kapadia reported in a research letter published in JACC: Cardiovascular Interventions.

CEP involves inserting a catheter in the right wrist during TAVR. The catheter deploys two filters, one in the left carotid artery, the other on the right carotid and radial arteries, to capture embolic debris. After the aortic valve is seated and the TAVR completed, the CEP filters are removed.

Potential effectiveness of filters

The study builds on work by Dr. Kapadia and colleagues reported in the PARTNER trial, which showed that CEP filters consistently captured embolized debris resulting in smaller brain lesions after TAVR than no filters. The hypothesis for the latest study, Dr. Kapadia said, “was that, even though the stroke rates may be very similar between the TAVR patients who had CEP and those who did not, the filter removed the large embolic particles, although there were small particles. In those cases, the consequence of stroke would be much less in the sense that you would have minor strokes, and you would either not die from the stroke or you would be able to walk home safely if you did have a stroke.”

In Dr. Kapadia’s experience, the filters capture up to 80% of embolic debris. The Cleveland Clinic used CEP in 96.5% of its TAVR cases in 2021, he said, adding that national rates are considerably lower because Medicare doesn’t reimburse for the procedure. An observational registry study reported that 13% of TAVR procedures used CEP by December 2019.

Dr. Kapadia said that the PROTECTED TAVR trial of the CEP device has completed data gathering and should report results later in 2022. The study randomized 3,000 patients to TAVR with or without CEP.

Dr. Kapadia noted that the findings require further study to validate them. “If it is all true, it will change the practice; it will make TAVR safer.”

David J. Cohen, MD, MSc, director of clinical and outcome research at the Cardiovascular Research Foundation in New York, called the study findings “provocative,” adding: “It makes points that we’ve seen in previous studies and certainly suggests there may be an important benefit of cerebral embolism protection that has not been well established to date.” Dr. Cohen is also director of academic affairs at St. Francis Hospital in Roslyn, N.Y.

The primary two findings of the study – lower risk of death and greater likelihood of discharge to home in CEP patients who had strokes after TAVR – “suggest that, while data on whether embolic protection actually prevents strokes is controversial and not at all definitive, these data suggest that perhaps one additional mechanism of benefit is that it’s making it much less severe when stroke occurs. That would obviously be of tremendous value.”

The findings are in line with other “suggestions that have not yet been explained,” Dr. Cohen said. “They may provide sort of a unifying explanation of why embolic protection may not prevent as many strokes as we thought but they may still be a very valuable adjunct.”

Boston Scientific distributes the Sentinel CEP device used in the study. Dr. Kapadia is the principal investigator of the PROTECTED TAVR trial, sponsored by Boston Scientific. Dr. Kapadia and study coauthors reported no other disclosures. Dr. Cohen is a consultant to Boston Scientific.

CEP involves inserting a catheter in the right wrist during TAVR. The catheter deploys two filters, one in the left carotid artery, the other on the right carotid and radial arteries, to capture embolic debris. After the aortic valve is seated and the TAVR completed, the CEP filters are removed.

Potential effectiveness of filters

The study builds on work by Dr. Kapadia and colleagues reported in the PARTNER trial, which showed that CEP filters consistently captured embolized debris resulting in smaller brain lesions after TAVR than no filters. The hypothesis for the latest study, Dr. Kapadia said, “was that, even though the stroke rates may be very similar between the TAVR patients who had CEP and those who did not, the filter removed the large embolic particles, although there were small particles. In those cases, the consequence of stroke would be much less in the sense that you would have minor strokes, and you would either not die from the stroke or you would be able to walk home safely if you did have a stroke.”

In Dr. Kapadia’s experience, the filters capture up to 80% of embolic debris. The Cleveland Clinic used CEP in 96.5% of its TAVR cases in 2021, he said, adding that national rates are considerably lower because Medicare doesn’t reimburse for the procedure. An observational registry study reported that 13% of TAVR procedures used CEP by December 2019.

Dr. Kapadia said that the PROTECTED TAVR trial of the CEP device has completed data gathering and should report results later in 2022. The study randomized 3,000 patients to TAVR with or without CEP.

Dr. Kapadia noted that the findings require further study to validate them. “If it is all true, it will change the practice; it will make TAVR safer.”

David J. Cohen, MD, MSc, director of clinical and outcome research at the Cardiovascular Research Foundation in New York, called the study findings “provocative,” adding: “It makes points that we’ve seen in previous studies and certainly suggests there may be an important benefit of cerebral embolism protection that has not been well established to date.” Dr. Cohen is also director of academic affairs at St. Francis Hospital in Roslyn, N.Y.

The primary two findings of the study – lower risk of death and greater likelihood of discharge to home in CEP patients who had strokes after TAVR – “suggest that, while data on whether embolic protection actually prevents strokes is controversial and not at all definitive, these data suggest that perhaps one additional mechanism of benefit is that it’s making it much less severe when stroke occurs. That would obviously be of tremendous value.”

The findings are in line with other “suggestions that have not yet been explained,” Dr. Cohen said. “They may provide sort of a unifying explanation of why embolic protection may not prevent as many strokes as we thought but they may still be a very valuable adjunct.”

Although the Sentinel cerebral embolism protection (CEP) device may not significantly reduce the overall stroke rate in patients after they’ve had transcatheter aortic valve replacement (TAVR), the device may improve survival and reduce the severity of procedure-related stroke, a retrospective database study reported.

Investigators led by Samir R. Kapadia, MD, chair of cardiovascular medicine at the Cleveland Clinic, analyzed outcomes of 136,382 patients in the Nationwide Readmissions Database who had TAVR in 2018-2019. The dataset included 10,201 people who received the Sentinel CEP device during TAVR.

The proportion of patients who had a stroke after TAVR was similar in both groups – 1.85% (189) in the CEP group and 1.94% (1,447) in the CEP nonusers – but, as Dr. Kapadia pointed out, the stroke outcomes between the two groups were noticeably different.

“Interestingly enough, what we found was that the people with the CEPs who had a stroke had half the mortality, and they were going home at a significantly higher rate, than the people who had a stroke and didn’t have CEPs,” Dr. Kapadia said in an interview. A previous registry study of 276,316 TAVR patients reported the overall rate of post-TAVR stroke declined from 2.75% to 2.3% over an 8-year period. The CEP device, approved in December 2017, had been available in the last 2 years of that study.

In the current retrospective database study, CEP patients went home after their post-TAVR strokes at a rate of 28.2%, compared with 19.9% for those who didn’t have CEP (P = .011). The in-hospital death rates were 6.3% and 11.8% for the respective groups (P = .023), and the 30-day readmission rates were 15.9% and 16.8% (P = .91). “The readmission rate is similar, but if you survive you get admitted,” Dr. Kapadia reported in a research letter published in JACC: Cardiovascular Interventions.

The chance that patients with severe aortic stenosis (AS) will receive aortic valve replacement (AVR) is worse than the flip of a coin, even a decade after the gamechanging transcatheter option became available, a new study suggests.

Of the study’s 6,150 patients with an indication or potential indication for AVR, 48% received the procedure at Massachusetts General Hospital and its partner institution Brigham and Women’s Hospital, both in Boston – both of which have active, high-volume transcatheter and surgical AVR (TAVR/SAVR) programs.

“Essentially, this is a best-case scenario. So, unfortunately, I think on the national level we are likely to see rates that are far worse than what we observed here,” senior author Sammy Elmariah, MD, PhD, Massachusetts General Hospital, told this news organization.

The volume of AVR increased more than 10-fold over the 18-year study period (2000 to 2017), driven by the exponential growth of TAVR, he noted. However, the graying of America led to an even greater increase in the number of patients with severe AS and an indication for AVR.

The study, led by Shawn X. Li, MD, MBA, of Mass General, was published in the March 8 issue of the Journal of the American College of Cardiology.

Previous research has provided equally compelling data on the undertreatment of AS, including a 2021 study using natural language processing (NLP) that found AVR use was just 35.6% within 1 year of diagnosis and varied wildly among managing cardiologists.

The present study used NLP tools to identify symptoms consistent with severe AS in the medical record coupled with echocardiographic data from 10,795 patients with severe AS (valve area <1 cm2). Patients were divided into four AS subtypes and then classified as having a class 1 indication (high-gradient AS with symptoms or reduced ejection fraction [EF]) or a potential class 2a indication (low-gradient AS with symptoms) for AVR.

Among patients with high-gradient AS and class 1 indication for AVR, 1 in 3 did not receive AVR over the study period, including 30% with a normal EF and 47% with a low EF.

In those with low-gradient AS, 67% with a normal EF and 62% with a low EF did not receive AVR. The low-gradient groups were significantly less likely to receive AVR both in the entire study period and in the more contemporary period from 2014 to 2017, despite the valvular heart disease guideline 2014 update indicating AVR was “reasonable” in patients with low-gradient AS – a 2a recommendation upgraded to class 1 in the most recent 2020 update.
 

Better survival

In patients with a class 1 or potential class 2a indication, AVR was associated with a significantly lower risk of mortality in all four AS subgroups:

• High gradient/normal EF: 3% vs. 15%; adjusted hazard ratio, 0.42
• High-gradient/low EF: 16% vs. 72%; aHR, 0.28
• Low-gradient/normal EF: 5% vs. 14%; aHR, 0.73
• Low-gradient/low EF: 11% vs. 34%; aHR, 0.48; P < .001 for all

“I think what we need to do is change the paradigm, such that patients with a valve area that is less than or equal to 1 [cm2] is severe aortic stenosis until proven otherwise, and that essentially establishes a premise by which we default to treat these patients unless we can prove that it is in fact moderate,” Dr. Elmariah said.

Unfortunately, the opposite is currently true today, he said, and the default is not to treat and put patients through surgery or an invasive TAVR procedure unless physicians can definitively prove that it is severe AS. But they’re not always correct and don’t always have the ability to truly differentiate moderate from severe disease.

“The question, therefore, is ‘What do we do with those patients?’” Dr. Elmariah asked. “I think if a patient has symptoms, then we are obligated to intervene, given the stark difference in mortality that one sees when these patients go undertreated.”
 

Sounding the alarm

Robert Bonow, MD, a professor of cardiology at Northwestern University in Chicago and a writing committee member for the 2014 guideline update, said the study is a “big wake-up call” and “the take-home message is that we are missing some patients who have treatable aortic stenosis.”

The sheer magnitude of the problem, however, can be difficult to fully ascertain from administrative data like this, he said. Notably, patients who did not receive AVR were significantly older, with 37% aged 81-90 years and 12% over age 90, and had a lower hematocrit and lower estimated glomerular filtration rate. But it’s not clear how many had cancer, end-stage renal disease, or severe lung disease, which could have factored into the decision to undergo AVR.

“What’s also an issue is that over 50% of patients had low gradient disease, which is very problematic and takes careful assessment in an individual patient,” said Dr. Bonow, who is also editor-in-chief of JAMA Cardiology. “That’s all being generated by a low valve area of less than 1 cm2 from echo reports, so that’s not necessarily a careful prospective echo assessment ... so some of the patients with low-gradient disease may not have true severe aortic stenosis.”

Dr. Elmariah agreed that echocardiogram reports are not always clear cut and pointed out that referral to a valve specialist was highly predictive of whether or not a patient underwent AVR, supporting the class 1 guideline recommendation.

He also noted that Mass General is launching the DETECT-AS trial to determine whether electronic physician notifications highlighting clinical practice guideline recommendations will improve AVR utilization over standard care in 940 patients with severe AS on echocardiogram, defined by a valve area less than 1 cm2.

Reached for comment, Catherine Otto, MD, director of the Heart Valve Clinic at the University of Washington, Seattle, and a fellow member of the 2014 guideline writing committee, said “this adds to the data [that] we’re undertreating severe aortic stenosis, and it continues to be surprising given the availability of transcatheter options.”

Increasingly active patterns of physical activity were linked with reduced rates of overall mortality and cardiovascular disease (CVD), but early rather than later in late life, in a 20-year follow-up cohort study.

In this population of people older than 65 years, researchers found that physical activity overall was associated with lower rates of incident CVD, particularly among men, and the association was strongest in people 70 to 75 years of age, rather than in older age groups.

They also looked at “trajectories,” or changes in activity over time, and found that a stable-high trajectory of activity was associated with a significantly lower risk for cardiovascular outcomes in men than in those with a stable-low trajectory. For women, more physical activity was consistently associated with lower CVD outcomes, although not statistically significantly so, except for overall mortality, which did reach significance.

Notably, the greatest reduction in cardiovascular risk was reported in people who did more than 20 minutes of physical exercise each day, and it was more pronounced in those 70 years of age.

Physical activity was also associated with a lower incidence of heart failure and coronary heart disease in older people, again especially early on in late life, reported Claudio Barbiellini Amidei, MD, University of Padua, Italy, and colleagues.

The data suggest that physical activity is more effective in preventing CVD onset when implemented early rather than later in life, noted Dr. Amidei in an email.

“The findings of our study are suggestive of a protective effect of physical activity in late-life on cardiovascular health. WHO recommendations for adults and older adults are to practice at least 20 minutes of moderate to vigorous physical activity per day. I believe this is a realistic target, and policy makers should raise awareness on the importance of achieving this goal at all ages, including in late-life,” Dr. Amidei said.

The study was published online Feb. 14 in Heart.

Previous research has demonstrated that the most benefit of high physical activity, compared with low, begins at about 60 years of age, and that is because younger people are at much lower risk, noted Carl “Chip” Lavie MD, FACC, medical director of cardiac rehabilitation and prevention, Ochsner Clinical School–The University of Queensland School of Medicine, New Orleans, who was not involved in the study.

“At quite old ages, for example over age 80, resistance exercise or weight training and balance training may be even more important than aerobic training,” he added.

Activity ‘trajectories’

The benefits of physical activity on cardiovascular risk are well established, the researchers note. Less clear is the role that trajectories of activity over time play, although research to date suggests a reduction in risk with increasing activity from mid-life to early old age, they write.

For the current analysis, the researchers assessed 3,099 Italian participants. Mean age was about 75 years, and baseline data were collected from 1995 to 1997.

Follow-up visits were conducted after 4 years and again after 7 years. Using hospital medical records and mortality data, the researchers were able to collect surveillance data through 2018. Hospital records, surveys, and clinical assessments helped them identify incident and prevalent cardiovascular diseases, such as stroke, coronary heart disease, and heart failure.

Participants’ physical activity patterns were classified as stable-high, low-increasing, high-decreasing, and stable-low. Exposure was evaluated at 70, 75, 80, and 85 years of age.

“In our analyses, we focused on moderate to vigorous physical activity, and these include a broad range of exercises, such as walking very briskly, playing tennis, [and] jogging, but comprise also other activities, such as gardening or doing household chores,” said Dr. Amidei.

Patterns of stable-low physical activity were linked to a significantly greater risk for cardiovascular outcomes in men than patterns of stable-high physical activity (hazard ratio, 0.48; 95% confidence interval, 0.27-0.86; P for trend = .002).

No significant relation was found between physical activity and stroke, the researchers note.

“The benefits of physical activity seem to lessen above the age of 75 years and seem more important in men,” noted Dr. Lavie. “This may be partly due to the higher risk of CVD in men. Women typically lag 13 to 15 years behind men for CVD but start catching up in older years.”

Limitations of the study include lack of information regarding physical activity during mid-life, the limited number of stroke events, the relatively few participants older than 85 years, and potential recall bias, the researchers note.

Another limitation was that the physical activity data were based on patient surveys collected 3 years apart and did not involve the use of an accelerometer, the researchers add.

“Future observational studies are required to confirm our findings and pathophysiological studies are warranted to examine the underlying biological mechanisms. Physical activity is likely to be beneficial at any age, but to summarize our findings, we could say that when it comes to being physically active, the sooner the better,” concluded Dr. Amidei.

Dr. Amidei reports no relevant financial relationships.

Previous research has demonstrated that the most benefit of high physical activity, compared with low, begins at about 60 years of age, and that is because younger people are at much lower risk, noted Carl “Chip” Lavie MD, FACC, medical director of cardiac rehabilitation and prevention, Ochsner Clinical School–The University of Queensland School of Medicine, New Orleans, who was not involved in the study.

“At quite old ages, for example over age 80, resistance exercise or weight training and balance training may be even more important than aerobic training,” he added.

Activity ‘trajectories’

The benefits of physical activity on cardiovascular risk are well established, the researchers note. Less clear is the role that trajectories of activity over time play, although research to date suggests a reduction in risk with increasing activity from mid-life to early old age, they write.

For the current analysis, the researchers assessed 3,099 Italian participants. Mean age was about 75 years, and baseline data were collected from 1995 to 1997.

Follow-up visits were conducted after 4 years and again after 7 years. Using hospital medical records and mortality data, the researchers were able to collect surveillance data through 2018. Hospital records, surveys, and clinical assessments helped them identify incident and prevalent cardiovascular diseases, such as stroke, coronary heart disease, and heart failure.

Participants’ physical activity patterns were classified as stable-high, low-increasing, high-decreasing, and stable-low. Exposure was evaluated at 70, 75, 80, and 85 years of age.

“In our analyses, we focused on moderate to vigorous physical activity, and these include a broad range of exercises, such as walking very briskly, playing tennis, [and] jogging, but comprise also other activities, such as gardening or doing household chores,” said Dr. Amidei.

Patterns of stable-low physical activity were linked to a significantly greater risk for cardiovascular outcomes in men than patterns of stable-high physical activity (hazard ratio, 0.48; 95% confidence interval, 0.27-0.86; P for trend = .002).

No significant relation was found between physical activity and stroke, the researchers note.

“The benefits of physical activity seem to lessen above the age of 75 years and seem more important in men,” noted Dr. Lavie. “This may be partly due to the higher risk of CVD in men. Women typically lag 13 to 15 years behind men for CVD but start catching up in older years.”

Limitations of the study include lack of information regarding physical activity during mid-life, the limited number of stroke events, the relatively few participants older than 85 years, and potential recall bias, the researchers note.

Another limitation was that the physical activity data were based on patient surveys collected 3 years apart and did not involve the use of an accelerometer, the researchers add.

“Future observational studies are required to confirm our findings and pathophysiological studies are warranted to examine the underlying biological mechanisms. Physical activity is likely to be beneficial at any age, but to summarize our findings, we could say that when it comes to being physically active, the sooner the better,” concluded Dr. Amidei.

Increasingly active patterns of physical activity were linked with reduced rates of overall mortality and cardiovascular disease (CVD), but early rather than later in late life, in a 20-year follow-up cohort study.

In this population of people older than 65 years, researchers found that physical activity overall was associated with lower rates of incident CVD, particularly among men, and the association was strongest in people 70 to 75 years of age, rather than in older age groups.

They also looked at “trajectories,” or changes in activity over time, and found that a stable-high trajectory of activity was associated with a significantly lower risk for cardiovascular outcomes in men than in those with a stable-low trajectory. For women, more physical activity was consistently associated with lower CVD outcomes, although not statistically significantly so, except for overall mortality, which did reach significance.

Notably, the greatest reduction in cardiovascular risk was reported in people who did more than 20 minutes of physical exercise each day, and it was more pronounced in those 70 years of age.

Physical activity was also associated with a lower incidence of heart failure and coronary heart disease in older people, again especially early on in late life, reported Claudio Barbiellini Amidei, MD, University of Padua, Italy, and colleagues.

The data suggest that physical activity is more effective in preventing CVD onset when implemented early rather than later in life, noted Dr. Amidei in an email.

“The findings of our study are suggestive of a protective effect of physical activity in late-life on cardiovascular health. WHO recommendations for adults and older adults are to practice at least 20 minutes of moderate to vigorous physical activity per day. I believe this is a realistic target, and policy makers should raise awareness on the importance of achieving this goal at all ages, including in late-life,” Dr. Amidei said.

New signals of a potential additive benefit from the nonsteroidal mineralocorticoid antagonist finerenone (Kerendia) and a sodium-glucose transporter 2 inhibitor in patients with type 2 diabetes and chronic kidney disease (CKD) emerged in a follow-up report from the FIDELITY analysis, which combined data from more than 13,000 patients who received finerenone in either of the two pivotal trials with the agent.

The analysis showed that the 877 patients enrolled in either the FIDELIO DKD or FIGARO DKD trials taking an SGLT2 inhibitor at baseline had a 37% relative reduction in their urinary albumin-to-creatinine ratio (UACR), compared with placebo-treated patients after a median of 3 years on treatment.

Among the remaining 12,149 patients who did not receive an SGLT2 inhibitor, finerenone cut the average UACR by 32%, compared with placebo, said Peter Rossing, DMSc, MD, who presented the findings on Feb. 27 at the World Congress of Nephrology 2022 in Kuala Lumpur, Malaysia.

Primary endpoint results for FIDELIO-DKD and FIGARO-DKD also suggest similar additive effects of finerenone plus an SGLT2 inhibitor.

Results of the composite renal endpoint in each study – progression to kidney failure, renal death, or at least a 57% decline in estimated glomerular filtration rate (eGFR) from baseline – showed a 58% relative risk reduction in patients who received agents from both drug classes and a 20% relative risk reduction in those who only received finerenone, a between-group difference that was not significant.

For the composite cardiovascular event endpoint – cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure – the rate fell by 37%, compared with placebo, in patients who also received an SGLT2 inhibitor, and by 13%, compared with placebo, in those who received finerenone but no SGLT2 inhibitor, also a difference that was not significant.

‘A lot of interest in finerenone’ in U.S.

“The benefits of finerenone on cardiovascular and kidney outcomes were consistent, irrespective of SGLT2 inhibitor use at baseline,” concluded Dr. Rossing, professor and head of research at the Steno Diabetes Center in Copenhagen.

The new findings are a “suggestion that the two classes might be additive [in their effects], but more data are needed,” Dr. Rossing said during his presentation.

But he cautioned that in both pivotal trials randomization did not consider SGLT2 inhibitor use. All patients in the two trials were already receiving a renin-angiotensin system (RAS) inhibitor as background treatment, either an ACE inhibitor or angiotensin-receptor blocker.

The consequence of treatment with finerenone combined with an SGLT2 inhibitor is of growing importance because “an SGLT2 inhibitor is now recommended in most guidelines” for the type of patients enrolled in the two finerenone trials, explained Dr. Rossing.

He also noted that the first guideline to recommend routine use of finerenone in indicated patients appeared recently in the annual update to Standards of Medical Care in Diabetes – 2022 published by the American Diabetes Association.

The 2022 Standards states: “In patients with CKD who are at increased risk for cardiovascular events or CKD progression or are unable to use an SGLT2 inhibitor, a nonsteroidal mineralocorticoid receptor antagonist (finerenone) is recommended to reduce CKD progression and cardiovascular events.”

Results from FIDELIO-DKD, reported in the New England Journal of Medicine in 2020, and the main study, FIGARO-DKD, published in the same journal in 2021, led the Food and Drug Administration to approve finerenone in July 2021 to slow the progression of renal disease in patients with type 2 diabetes and CKD.

“My impression is that in the United States there is a lot of interest in finerenone,” Dr. Rossing said during the discussion following his presentation.

Finerenone has also been recently approved in the European Union.
 

‘Consistent’ benefits irrespective of SGLT2 inhibitors

“The cardiovascular and kidney benefits of finerenone were consistent irrespective of SGLT2 inhibitor use. This is definitely interesting and warrants a randomized controlled trial” to examine the relationship in a more rigorous way, commented Tejas Desai, MD, a nephrologist with the Department of Veterans Affairs, Charlotte, N.C.

That study, CONFIDENCE, is on its way, Dr. Rossing said during his talk. The randomized phase 2 trial has a planned enrollment of 800 patients with type 2 diabetes and CKD and three treatment groups: finerenone plus placebo, the SGLT2 inhibitor empagliflozin (Jardiance) plus placebo, or finerenone plus empagliflozin. The study will launch later in 2022 and has a planned completion date of late 2023.

“SGLT2 inhibitors, compared with finerenone, is where all of this is headed. We need a large trial that adjudicates the best medication to use with a RAS inhibitor,” Dr. Desai said in an interview.

The new analyses from the combined FIDELITY study expand on a previous report presented at the 2021 annual congress of the European Society of Cardiology and published in the European Heart Journal.
 

‘Impressive’ effect on cardiovascular events

The main findings from FIDELITY presented in those earlier reports, in 13,026 patients, showed there was a significant 14% relative reduction in the composite cardiovascular endpoint with finerenone, compared with placebo, during a median 3 years of follow-up.

The same report documented, in the total combined cohort, a significant 23% relative reduction in the composite renal endpoint in those taking finerenone compared with placebo.

“Reducing the risk of cardiovascular endpoints by a relative 14% is impressive,” and the time course showed a “relatively quick onset of action,” Dr. Desai noted.

He also characterized the enrolled patients, which included many with stage 3 or 4 CKD, as “not the sickest population of patients with CKD,” but rather “relatively healthier patients with CKD.”

Dr. Desai also downplayed the importance of the observed reduction in UACR associated with finerenone in FIDELITY.

“UACR is a surrogate marker. Results from many studies have shown improvements in UACR only to not show protection against falls in eGFR rate,” Dr. Desai said.

He was also reassured by the low incidence of hyperkalemia that led to discontinuation, which occurred in 1.7% of patients taking finerenone and in 0.6% of those taking placebo.

The types of patients enrolled in FIDELIO-DKD and FIGARO-DKD, who did not have eGFR rates below 25 mL/min per 1.73 m², are not particularly susceptible to this adverse effect, he said, noting, “I’m not overly concerned with hyperkalemia in this CKD population.

“I’m more concerned about [hyperkalemia in] patients with CKD and an eGFR of less than 25 mL/min per 1.73 m², but this was less than 1% of the enrolled population,” Dr. Desai observed.

FIDELIO-DKD, FIGARO-DKD, and FIDELITY were sponsored by Bayer, which markets finerenone (Kerendia). Dr. Rossing reported being a consultant for Bayer and other drug companies, and receiving research funding from AstraZeneca and Novo Nordisk. Dr. Desai reported no relevant financial relationships.

Strong new evidence on the need to use an appropriately sized cuff in blood pressure measurement has come from the cross-sectional randomized trial Cuff(SZ).

The study found that in people in whom a small adult cuff was appropriate, systolic BP readings were on average 3.6 mm Hg lower when a regular adult size cuff was used.

However, systolic readings were on average 4.8 mm Hg higher when a regular cuff was used in people who required a large adult cuff and 19.5 mm Hg higher in those needing an extra-large cuff based on their mid-arm circumference.

The diastolic readings followed a similar pattern (-1.3 mm Hg, 1.8 mm Hg, and 7.4 mm Hg, respectively).

“We found that using the regular adult cuff in all individuals had striking differences in blood pressure,” lead author Tammy M. Brady, MD, PhD, Johns Hopkins University School of Medicine, Baltimore, told this news organization. “And that has a lot of clinical implications.”
