USPSTF says evidence still lacking for AFib screening in asymptomatic patients

A new statement from the U.S. Preventive Services Task Force concludes that current evidence is insufficient to assess the balance of benefits and harms of screening for atrial fibrillation (AFib) in asymptomatic adults.

The guidance is similar to the task force’s 2018 statement on screening for AFib with electrocardiography in asymptomatic adults 65 years or older, but lowers the inclusion age to adults 50 years or older.

“This 2021 evidence review included searching for evidence on additional screening methods such as automated blood pressure cuffs, pulse oximeters, and consumer devices such as smartwatches and smartphone apps. However, even with this expanded scope, the USPSTF did not find evidence to recommend for or against screening for AF,” the task force states.

The prevalence of increases in age from less than 0.2% in adults younger than 55 years to about 10% in those 85 years or older, the group says. The prevalence is higher in men than in women, but it is uncertain if it differs by race and ethnicity.

Although AFib substantially increases the risk for stroke, the stroke risk associated with subclinical AFib, particularly that of shorter duration lasting less than 24 hours or of lower burden, as might be detected by some screening approaches, is “uncertain,” the task force adds.

The updated recommendations were published online in JAMA, along with a separate evidence report and editorial.

The task force reviewed 26 studies in 113,784 patients, including 12 new to the update.

Studies showed that systematic screening detected significantly more AFib than no screening or pulse palpation (absolute difference, 1.0%-4.8% over up to 12 months). In two of the trials, however, only 10.7% and 44.5% of participants actually received the screening test.

The review included three randomized trials of screening vs. no screening that reported on health outcomes, but only one, STROKESTOP, was powered for health outcomes. It found a significantly lower risk for the primary composite endpoint of ischemic or hemorrhagic stroke, system embolism, bleeding leading to hospitalization, and all-cause mortality with twice-daily intermittent single-lead ECG monitoring for 14 days, compared with no screening. However, there were no significant differences in any of the individual outcomes of the composite endpoint.

“Additionally, and probably the most important thing to appreciate for the STROKESTOP study is that it has several limitations,” task force member Gbenga Ogedegbe, MD, MPH, of New York University told this news organization. The intervention was not masked, and outcomes weren’t centrally adjudicated.

Further, “about 11% of patients in the trial had a history of transient ischemic attack (TIA), stroke, or embolism and the population that we’re looking at within the task force are people without symptoms or history of stroke or ischemic attack,” he said. “That’s the fundamental difference here. So those limitations make it difficult to say that STROKESTOP actually has benefit.”

Notably absent from the review was the recent LOOP study, which found no significant benefit on outcomes with continuous monitoring with an implantable loop recorder (ILR) over usual care in older adults.

While it “offers some context for this issue,” it was not eligible for inclusion because 25% of the population had a prior history of stroke, TIA, or embolism and “because this screening approach may not be feasible for primary care settings,” lead author of the Evidence Report Leila Kahwati, MD, MPH, from RTI International’s Social and Health Organizational Research and Evaluation Program and the University of North Carolina at Chapel Hill, explained in an email.

Treatment with warfarin (mean, 1.5 years) was associated with a lower risk for ischemic stroke (relative risk, 0.32) and all-cause mortality (relative risk, 0.68), while direct oral anticoagulants were associated with a lower incidence of stroke (adjusted odds ratio range, 0.32-0.44). Patients had an increased risk for major bleeding with both warfarin (pooled relative risk, 1.8) and direct-acting oral anticoagulants (odds ratio, 1.38-2.21), but confidence intervals did not exclude a null effect.

The USPSTF found no trials that reported on the benefits of anticoagulation therapy in screen-detected patients.

In an accompanying editorial Philip Greenland, MD, points out that the task force’s conclusion differs from the 2020 European Society of Cardiology AFib guideline, which endorses opportunistic screening for AFib by pulse palpation or ECG rhythm strip in patients 65 years or older (class I recommendation) and advises that clinicians consider systematic ECG screening to detect AFib in people 75 years or older, or those at high risk for stroke (class IIa).

To possibly resolve whether screening for AFib in asymptomatic patients is justified, “future trials may need to consider enrolling only higher risk patients and identifying those with AF of longer duration,” said Dr. Greenland, JAMA editor and professor of preventive medicine and medicine at Northwestern University, Chicago.

“One important point raised by the LOOP trial is whether there is a threshold for AF duration that is most strongly associated with stroke risk and therefore most likely to benefit from anticoagulation,” he writes. Indeed, the LOOP authors themselves questioned whether the trial’s short AFib duration of 6 minutes may have led to many low-risk patients being diagnosed and treated.

“Additionally, trials need to recognize the need for longer monitoring periods (preferably continuous), and perhaps novel wearables will allow long-term monitoring, with accurate interpretation of the ECG and long-term adherence,” Dr. Greenland said.

In a related editorial in JAMA Internal Medicine, John Mandrola, MD, Baptist Health Louisville, Ky., and Andrew Foy, MD, Pennsylvania State University, Hershey, point out that continuous ILR monitoring in the LOOP trial found threefold more AFib and led to 2.7-fold higher rates of oral anticoagulation use, compared with standard care. Yet, there was no statistically significant difference in stroke reduction, and the 20% relative reduction in thromboembolic complications in the screened group was offset by a 26% relative increase in major bleeding.

“Perhaps the most remarkable aspect of the AF screening trials is that as the tools for screening improve, from a single 12-lead ECG to 14-day recordings and then the always-on ILR, more AF is detected and more [oral anticoagulant] is used, yet there is little demonstrable improvement in outcomes,” Dr. Mandrola and Dr. Foy write.

The editorialists also point to the potential for rhythm monitoring to lead to misdiagnosis and downstream cascades of care. “If you assume a 2% AF prevalence, even a device with 98% specificity will misdiagnose approximately 2000 individuals for every million screened.”

Dr. Mandrola told this news organization that the “greatest value” of these reports on AF screening and the critical appraisal of them is as an exercise in thinking about the limits of screening for disease. As James Maxwell Glover Wilson and Gunner Jungner wrote in their 1968 textbook, “Principles and Practice of Screening for Disease”: “in theory, screening is an admirable method of combating disease … [but] in practice, there are snags.”

“It would be good for the public to understand these snags…because they also apply to cancer, coronary calcium testing, and vascular screening as well,” Dr. Mandrola said.

Asked whether it’s possible to put the genie back in the bottle now that every other patient in clinic may have an ECG on their wrist, Dr. Ogedegbe said, “if a patient has no history of stroke or TIA and is 50 years or older, really, monitoring with these devices for AFib, there’s no evidence for or against doing that. Ultimately, the clinician has got to use their clinical judgment in talking to these patients.”

A related editorial in JAMA Cardiology suggests that, to be effective, the movement toward consumer-based screening must first show that such an approach improves outcomes and must deal with the paradox that those at highest risk for AFib and AFib-related stroke may be the least likely to own these technologies unless supported by the healthcare system.

“In addition, appropriate care pathways for confirming the diagnosis and, if necessary, initiating appropriate treatment in individuals with positive findings will need to be established,” Rod Passman, MD, Northwestern University, and Ben Freedman, MBBS, PhD, University of Sydney, Australia, say. “It will also be critical to ensure that device costs and variable technological literacy do not create barriers to making screening accessible to all those at risk.”

Finally, in a related editorial in JAMA Network Open Matthew Kalscheur, MD, and Zachary D. Goldberger, MD, both from the University of Wisconsin-Madison, say the potential benefits of early AFib detection should extend beyond stroke prevention.

“Patients identified with AF likely would benefit from targeted management of modifiable risk factors that contribute to AF, including obesity, hypertension, alcohol use, sleep apnea, smoking, and diabetes,” they write.

All members of the USPSTF receive travel reimbursement and an honorarium for participating in USPSTF meetings. Dr. Ogedegbe has a study included in the Evidence-based Practice Center report for this topic. Dr. Kahwati reported no relevant financial conflicts of interest. Dr. Greenland reported receiving research grants from the National Institutes of Health and from the American Heart Association. Dr. Mandrola is a regular contributor to this news organization. Dr. Foy, Dr. Kalscheur, and Dr. Goldberger reported no relevant financial relationships.

No amount of alcohol safe for the heart: WHF

Article Type

Thu, 01/27/2022 - 11:49

The widely held notion that consuming small to moderate amounts of alcohol is good for cardiovascular health is not supported by the data, the World Heart Federation says in a new policy brief.

In fact, the evidence is clear that any level of drinking can contribute to loss of a healthy life, the organization says.

“Over the past several decades, the prevalence of cardiovascular disease has nearly doubled, and alcohol has played a major role in the incidence of much of it,” the WHF said in the brief.

“The portrayal of alcohol as necessary for a vibrant social life has diverted attention from the harms of alcohol use, as have the frequent and widely publicized claims that moderate drinking, such as a glass of red wine a day, can offer protection against cardiovascular disease,” Monika Arora, PhD, member of the WHF advocacy committee and coauthor of the brief, said in a news release.

“These claims are at best misinformed and at worst an attempt by the alcohol industry to mislead the public about the danger of their product,” Dr. Arora added.

The WHF conclusions follow a report in the Lancet based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), which found that there is no safe level of alcohol consumption.

In 2019, nearly 2.4 million deaths were attributed to alcohol, accounting for 4.3% of all deaths globally and 12.6% of deaths in men 15 to 49 years of age.

Even small amounts of alcohol have been shown to raise the risk for cardiovascular disease, including coronary disease, stroke, heart failure, hypertensive heart disease, cardiomyopathy, atrial fibrillation, and aneurysm, the WHF notes.

Studies that claim otherwise are largely based on purely observational research, which fails to account for relevant cofactors, the organization writes.

Based on their summary of the evidence to date, there is no reliable correlation between moderate alcohol consumption and a lower risk for cardiovascular disease.

Alcohol use is also a “major avoidable risk factor” for cancer, digestive diseases, intentional and unintentional injuries, and several infectious diseases, the WHF says.

Alcohol use also has significant economic and social costs, which include costs to individuals and health systems, productivity losses, as well as the increased risk for violence, homelessness, and criminal activity.

The WHF policy brief calls for “urgent and decisive action” to tackle the unprecedented rise in alcohol-related death and disability worldwide.

Recommended actions include boosting restrictions on alcohol availability; advancing and enforcing drinking and driving countermeasures; increasing access to screening, brief interventions, and treatment for alcohol use disorder; enforcing bans on alcohol advertising; establishing a uniform minimum legal drinking age; and mandating health warnings on alcohol products.

Even small amounts of alcohol have been shown to raise the risk for cardiovascular disease, including coronary disease, stroke, heart failure, hypertensive heart disease, cardiomyopathy, atrial fibrillation, and aneurysm, the WHF notes.

Studies that claim otherwise are largely based on purely observational research, which fails to account for relevant cofactors, the organization writes.

Based on their summary of the evidence to date, there is no reliable correlation between moderate alcohol consumption and a lower risk for cardiovascular disease.

Alcohol use is also a “major avoidable risk factor” for cancer, digestive diseases, intentional and unintentional injuries, and several infectious diseases, the WHF says.

Alcohol use also has significant economic and social costs, which include costs to individuals and health systems, productivity losses, as well as the increased risk for violence, homelessness, and criminal activity.

The WHF policy brief calls for “urgent and decisive action” to tackle the unprecedented rise in alcohol-related death and disability worldwide.

Recommended actions include boosting restrictions on alcohol availability; advancing and enforcing drinking and driving countermeasures; increasing access to screening, brief interventions, and treatment for alcohol use disorder; enforcing bans on alcohol advertising; establishing a uniform minimum legal drinking age; and mandating health warnings on alcohol products.

Celebratory binge drinking a potential trigger for new-onset AFib

Article Type

Wed, 01/26/2022 - 11:50

Emergency department visits for atrial fibrillation (AFib) appear to go up on days around some annual events in the United States that many people commemorate by consuming alcohol in excess – think Christmas, New Year’s Day, and Super Bowl Sunday.

The novel finding seemed especially true for people without a previous AFib diagnosis, suggesting that alcohol intake, and especially binge drinking, “may acutely enhance the risk” of new-onset AFib, propose researchers in their Jan. 12 report for the inaugural issue of Nature Cardiovascular Research.

Leveraging an international database of breathalyzer test results, the group saw jumps in alcohol intake across several days surrounding eight “recurrent, nationally recognized events,” which also included U.S. Independence Day and the FIFA World Cup.

They then compared the timing of those events to ED visits linked to acute alcohol ingestion and, separately, to ED visits coded for AFib in 10 years of data that cover all of California.

Collectively, the eight annual occasions for heavy alcohol use corresponded to spikes in both kinds of ED visit. Their relationship to AFib-related visits overall grew in strength when the analysis was restricted to new AFib diagnoses.

The researchers acknowledge the limitations of their observational study. Still, the findings represent “the first evidence that acute exposure to alcohol can lead to a given atrial fib episode in a short period of time, even among those without an established AFib diagnosis,” senior author Gregory M. Marcus, MD, MAS, University of California, San Francisco, told this news organization.

“The observation that this was detectable in the general population is a warning to those who drink heavily that any one episode of excessive alcohol consumption could land them in the ED with atrial fibrillation,” he said.

It’s “definitely speculation,” but such ED visits could represent an opportunity for individuals to link their new arrhythmia with a specific episode of excessive drinking, strengthening the message that the two are likely connected, Dr. Marcus observed. The experience could potentially inspire some to “reduce or eliminate” their alcohol intake in an effort to avoid future AFib.

The group obtained data from 2014 to 2016 on more than 1.2 million breath alcohol measurements from about 36,000 people in 59 countries, half residing in the United States, who used commercially available breathalyzer devices from one manufacturer (BACtrack).  

The 8 days marking recurrent nationally recognized events, and the days before and after them, were associated with mean blood-alcohol concentrations in the top fifth percentile for the year.

The same eight occasions marked significant bumps in ED visits related to acute alcohol ingestion in records from the California Office of Statewide Health Planning and Development (OSHPD), which documented almost 1.2 million such visits from 2005 to 2015.

Collectively in adjusted analysis, the eight nationally recognized events, compared with other days of the year, accounted for 2,640 excess alcohol-related ED visits per 100,000 person-years across all of California (P < .001).

Separately, ED visits coded for a diagnosis of AFib concentrated significantly around those same 8 days, on which there was an excess of 719 such AFib-related visits per 100,000 person-years (P = .008).

The analysis was replicated after exclusion of OSHPD records from anyone with a previous AFib-related ED visit or hospitalization, or previous outpatient procedure related to AFib, such as ablation or cardioversion. It saw 1,757 excess ED visits per 100,000 person-years (P < .001) for what was considered new-onset AFib in association with the eight nationally recognized events, compared with the rest of the year.  

The implication, that a bout of alcohol use leading to an ED visit can acutely raise the risk for a first episode of AFib, was subjected to a “negative control analysis” that focused on ED visits for supraventricular tachycardia. It showed no significant relationships with the eight nationally recognized events.

“We think that helps demonstrate that it’s not just more ED visits, more palpitations, or more heart-related visits per se” associated with acute alcohol use, Dr. Marcus said, “but that it’s something fairly specific to AFib.”

The authors declare no competing interests. Dr. Marcus has previously reported research with Medtronic, Eight Sleep, and Baylis; consulting for InCarda Therapeutics and Johnson & Johnson; and equity in InCarda Therapeutics as cofounder.

CVS Caremark formulary change freezes out apixaban

Article Type
Changed
Thu, 01/20/2022 - 07:00

Patients looking to refill a prescription for apixaban (Eliquis) through CVS Caremark may be in for a surprise following its decision to exclude the direct oral anticoagulant (DOAC) from its formulary starting Jan. 1.

The move leaves just one DOAC, rivaroxaban (Xarelto), on CVS’ commercial formulary and is being assailed as the latest example of “nonmedical switching” used by health insurers to control costs.

In a letter to CVS Caremark backed by 14 provider and patient organizations, the nonprofit Partnership to Advance Cardiovascular Health (PACH) calls on the pharmacy chain to reverse its “dangerously disruptive” decision to force stable patients at high risk of cardiovascular events to switch anticoagulation, without an apparent option to be grandfathered into the new plan.

PACH president Dharmesh Patel, MD, Stern Cardiovascular Center, Memphis, called the formulary change “reckless and irresponsible, especially because the decision is not based in science and evidence, but on budgets. Patients and their health care providers, not insurance companies, need to be trusted to determine what medication is best,” he said in a statement.

Craig Beavers, PharmD, vice president of Baptist Health Paducah, Kentucky, said that, as chair of the American College of Cardiology’s Cardiovascular Team Section, he and other organizations have met with CVS Caremark medical leadership to advocate for patients and to understand the company’s perspective.

“The underlying driver is cost,” he told this news organization.

Current guidelines recommend DOACs in general for a variety of indications, including to reduce the risk of stroke and embolism in nonvalvular atrial fibrillation and to prevent deep vein thrombosis, but there are select instances where a particular DOAC might be more appropriate, he observed.

“Apixaban may be better for a patient with a history of GI bleeding because there’s less GI bleeding, but the guidelines don’t necessarily spell those things out,” Dr. Beavers said. “That’s where the clinician should advocate for their patient and, unfortunately, they are making their decision strictly based off the guidelines.”

Requests to speak with medical officers at CVS Caremark went unanswered, but its executive director of communications, Christina Peaslee, told this news organization that the formulary decision “maintains clinically appropriate, cost-effective prescription coverage” for its clients and members.

“Both the American Heart Association/American College of Cardiology/Heart Rhythm Society and 2021 CHEST guidelines recommend DOACs over warfarin for treatment of various cardiology conditions such as atrial fibrillation, but neither list a specific agent as preferred – showing that consensus clinical guidelines do not favor one over the other,” she said in an email. “Further, Xarelto has more FDA-approved indications than Eliquis (e.g., Xarelto is approved for a reduction in risk of major CV events in patients with CAD or PAD) in addition to all the same FDA indications as Eliquis.”

Ms. Peaslee pointed out that all formulary changes are evaluated by an external medical expert specializing in the disease state, followed by review and approval by an independent national Pharmacy & Therapeutics Committee.

The decision to exclude apixaban is also limited to a “subset of commercial drug lists,” she said, although specifics on which plans and the number of affected patients were not forthcoming.

The choice of DOAC is a timely question in cardiology, with recent studies suggesting an advantage for apixaban over rivaroxaban in reducing the risk of recurrent venous thromboembolism, as well as reducing the risk of major ischemic or hemorrhagic events in atrial fibrillation.

Ms. Peaslee said CVS Caremark closely monitors medical literature for relevant clinical trial data and that most clients allow reasonable formulary exceptions when justified. “This formulary exceptions process has been successfully used for changes of this type and allows patients to get a medication that is safe and effective, as determined by their prescriber.”

The company will also continue to provide “robust, personalized outreach to the small number of members who will need to switch to an alternative medication,” she added.

Dr. Beavers said negotiations with CVS are still in the early stages, but, in the meantime, the ACC is providing health care providers with tools, such as drug copay cards and electronic prior authorizations, to help ensure patients don’t have gaps in coverage.

In a Jan. 14 news release addressing the formulary change, ACC notes that a patient’s pharmacy can also request a one-time override when trying to fill a nonpreferred DOAC in January to buy time if switching medications with their clinician or requesting a formulary exception.

During discussions with CVS Caremark, it says the ACC and the American Society of Hematology “underscored the negative impacts of this decision on patients currently taking one of the nonpreferred DOACs and on those who have previously tried rivaroxaban and changed medications.”

The groups also highlighted difficulties with other prior authorization programs in terms of the need for dedicated staff and time away from direct patient care.

“The ACC and ASH will continue discussions with CVS Caremark regarding the burden on clinicians and the effect of the formulary decision on patient access,” the release says.

In its letter to CVS, PACH argues that the apixaban exclusion will disproportionately affect historically disadvantaged patients, leaving those who can least afford the change with limited options. Notably, no generic is available for either apixaban or rivaroxaban.

The group also highlights a 2019 national poll, in which nearly 40% of patients who had their medication switched were so frustrated that they stopped their medication altogether.

PACH has an online petition against nonmedical switching, which at press time had garnered 2,126 signatures.

One signee, Jan Griffin, who survived bilateral pulmonary embolisms, writes that she has been on Eliquis [apixaban] successfully since her hospital discharge. “Now, as of midnight, Caremark apparently knows better than my hematologist as to what blood thinner is better for me and will no longer cover my Eliquis prescription. This is criminal, immoral, and unethical. #StopTheSwitch.”

What does a pig-to-human heart transplant mean for medicine?

Article Type
Changed
Thu, 01/13/2022 - 15:17

Scientific achievements usually raise big new questions, and the remarkable surgery that took place on Jan. 7, when Maryland resident David Bennett was transplanted with a genetically modified heart from a pig, has been no different.

The 57-year-old with end-stage heart failure had been repeatedly turned down for a standard transplant and was judged a poor candidate for a ventricular assist device. Now his new heart is beating soundly and apparently accepted by his immune system as Mr. Bennett, his physicians at the University of Maryland where the procedure took place, and indeed the world set out on a journey with far more unknowns than knowns.

“I think even just a couple of years ago, people felt that xenotransplantation for the heart and other organs was still a long way off. And it seems like it’s started to move very quickly,” Larry A. Allen, MD, University of Colorado, Aurora, said in an interview.

Demand for donor hearts far outstrips supply, and despite advances in the development of ventricular assist pumps and artificial hearts, “there are still significant limitations to them in terms of clotting, stroke, and infection. We’ve seen the use of those devices plateau,” Dr. Allen said. “So, the concept of a nonhuman source of organs is exciting and very much in need, if people can get it to work.”

“I really credit the surgeons at the University of Maryland for courageous clinical work and a brilliant scientific innovation,” Clyde W. Yancy, MD, MSc, Northwestern University, Chicago, said in an interview. “But it’s always in the implementation that we have to hold our breath.” Heart xenotransplantation is an old idea that “has never before been successful,” he said. And standard heart transplantation has set a high bar, with a 1-year survival of about 90% and low 1-year risk for rejection. Whether the new procedure can meet that standard is unknown, as is its potential for complications, such as chronic rejection or cancers due to long-term immunosuppression. Those are “major questions requiring more time and careful follow-up.”

‘Still a nascent technology’

“This is an exciting and courageous step forward in heart transplantation, and kudos to the team at the University of Maryland,” said Mandeep R. Mehra, MD, Brigham and Woman’s Hospital, Boston. But “there are many challenges here.”

The procedure’s 10 gene modifications were reportedly aimed at preventing hyperacute rejection of the heart and its excessive growth after transplantation, and making the organ less immunogenic, Dr. Mehra said in an interview. But even if those goals are met, could the same changes potentially impede the heart’s adaptation to human physiology, such as during ambulation or stress?

That kind of adaptation may become important. For example, Dr. Mehra observed, normally a pig heart “provides flow in a four-footed configuration, and pig temperature is inherently higher than humans by several degrees, so it will be functioning in a relatively hypothermic environment.”

Transplantation remains the gold standard for patients with advanced heart failure despite modern medical and device therapy, Dr. Allen agreed. But “if we can raise pig hearts that provide the organ, and it can be implanted with a surgery that’s been done for 50 years, and rejection can be managed with gene editing and tailored immunosuppression, then it’s not hard to think about this very rapidly replacing a lot of what we do in the advanced heart failure and transplantation world.”

Certainly, it would be a major advance if the gene editing technique successfully improves the heart’s immunologic compatibility, Dr. Yancy noted. But do we have enough genomic knowledge to select gene deletions and insertions in the safest way for a successful outcome? “We have to appreciate that this is still a nascent technology, and we should be careful that there might be consequences that we haven’t anticipated.”

For example, he said, the xenotransplantation and gene-modifying techniques should be explored in a range of patients, including older and younger people, women and men, and people of different ethnicities and races.

“There may be some differences based on ancestry, based on gender, based on aging, that will influence the way in which these engineered donor hearts are experienced clinically,” Dr. Yancy said.

The xenotransplantation technique’s potential impact on health equity should also be considered, as it “almost assuredly will be a very expensive technology that will be utilized in a very select population,” he noted. “We need to have a really wide lens to think about all of the potential ramifications.”
 

 

 

‘This field needs to evolve’

Dr. Mehra also flagged the procedure’s potential cost should it become mainstream. Perhaps that would promote dialogue on how to primarily use it “after legitimately exhausting all available options, such as total artificial heart support.”

It might also teach the field to take greater advantage of the many donated hearts discarded as suboptimal. “The general usage rate for offered organs is around a third,” despite opportunities to expand use of those that are “less than perfect,” Dr. Mehra said. “I think that the field will grow with the community focusing on reduced discards of current available heart organs, and not necessarily grow because of the availability of ‘xeno-organs.’ ”

“This field needs to evolve because we’re actively transplanting patients today. But in my mind, the real future is to have such a sufficient understanding of the biology of left ventricular dysfunction that transplantation is a rare event,” Dr. Yancy proposed.

“I’m not certain that heart transplantation per se is the endgame. I think the avoidance of transplantation is the real endgame,” he said. “This may be controversial, but my vision of the future is not one where we have a supply of animals that we can use for transplantation. My vision of the future is that heart transplantation becomes obsolete.”

Scientific achievements usually raise big new questions, and the remarkable surgery that took place on Jan. 7, when Maryland resident David Bennett was transplanted with a genetically modified heart from a pig, has been no different.

The 57-year-old with end-stage heart failure had been repeatedly turned down for a standard transplant and was judged a poor candidate for a ventricular assist device. Now his new heart is beating soundly and apparently accepted by his immune system as Mr. Bennett, his physicians at the University of Maryland where the procedure took place, and indeed the world set out on a journey with far more unknowns than knowns.

Pig heart successfully transplanted to man

Article Type
Changed
Tue, 01/11/2022 - 09:46

A genetically modified pig heart has been successfully transplanted into a 57-year-old man who had no other treatment options but is “doing well” 3 days after the procedure, officials at the University of Maryland Medical Center (UMMC), Baltimore, announced Jan. 10.

“This organ transplant demonstrated for the first time that a genetically modified animal heart can function like a human heart without immediate rejection by the body,” they said.

Three genes associated with antibody-mediated rejection had been knocked out in the pig supplying the transplanted heart, and six human genes associated with immune acceptance of the organ had been inserted into the pig’s genome, notes a UMMC press release.

“Lastly, one additional gene in the pig was knocked out to prevent excessive growth of the pig heart tissue, which totaled 10 unique gene edits made in the donor pig,” the release states.

The patient, Maryland resident David Bennett, had required mechanical circulatory support to stay alive but was rejected for standard heart transplantation at UMMC and other centers. He was ineligible for an implanted ventricular assist device due to ventricular arrhythmias.

Mr. Bennett “is being carefully monitored over the next days and weeks to determine whether the transplant provides lifesaving benefits,” the announcement says.

“We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future,” notes a quote from Bartley P. Griffith, MD, the UMMC surgeon who performed the procedure.

The pig supplying the heart was provided to the center by Revivicor (Blacksburg, Virginia), a regenerative medicine company. An experimental antirejection medication (Kiniksa Pharmaceuticals; Lexington, Massachusetts) was also used, in addition to standard immunosuppressants.

Cardiac device interrogation after death ‘richly informative’

Article Type
Changed
Fri, 01/07/2022 - 09:48

 

Interrogating the cardiac implantable electronic device (CIED) after death can yield important information about critical device malfunction, premortem abnormalities, and the mechanism and timing of death, a new study suggests.

Postmortem CIED interrogation is “richly informative” in assisting both cardiac and forensic investigations and “should be considered for select patients with CIEDs undergoing autopsy,” say Elizabeth Paratz, MBBS, department of cardiology, Baker Heart and Diabetes Institute, Prahran, Australia, and colleagues.

Their study results were published online in JACC: Clinical Electrophysiology. 

Cause of death revealed in half of cases

They reviewed CIED interrogations in 260 deceased individuals undergoing medicolegal investigation of sudden death (162 patients) or unexplained death (98 patients) by the Victorian Institute of Forensic Medicine between 2005 and 2020.

Roughly two-thirds were male (68.8%) and their median age was 72.8 years; 202 patients had pacemakers, 56 had defibrillators, and 2 had loop recorders. The cause of death was cardiac in 79.6% of cases.

Postmortem CIED interrogation was successful in 98.5% cases and directly informed cause of death in 131 cases (50.4%), with fatal ventricular arrhythmias identified in 121 patients.

CIED interrogation assisted in determining the cause of death in 63.6% of cases of sudden death and 28.6% of nonsudden death cases.

In 20 cases (7.7%), CIED interrogation uncovered potential device malfunction. Issues included failure to appropriately treat ventricular arrhythmias in 13 cases; lead issues in 3 cases, including 2 cases resulting in failure to treat ventricular arrhythmias; as well as battery depletion in 6 cases.

In 72 patients (27.7%), the device recorded abnormalities in the 30 days before death. These abnormalities included nonsustained ventricular tachycardia in 26 cases, rapid atrial fibrillation in 17, elective replacement indicator or end-of-life status in 22, intrathoracic impedance alarms or lead issues in 3 each, and therapy delivered in 1 instance.

“In several cases, the absence of an arrhythmia carried medicolegal implications: For example, in eight fatal motor vehicle accident cases, only one patient had a ventricular arrhythmia documented on their CIED,” Dr. Paratz and colleagues report.

And in six cases in which the patient was found dead after a prolonged period, CIED interrogation determined time of death. And in one case, CIED interrogation was the primary means of identifying the patient.

Still, postmortem CIED interrogation remains uncommon, the study team notes.

They point to a 2007 survey of Chicago morticians that found roughly 370 CIEDs were explanted per year prior to cremation, but only 4% of morticians had ever returned a CIED to the manufacturer for analysis.

“Encouraging postmortem interrogation of CIEDs may assist in postmarketing surveillance for critical faults, as well as in providing an electrophysiological appraisal of terminal rhythms and device responses in a variety of physiological scenarios,” the researchers say.

The study had no commercial funding. Dr. Paratz is supported by a National Health and Medical Research Council/National Heart Foundation cofunded Postgraduate Scholarship, Royal Australasian College of Physicians JJ Billings Scholarship, and PSA Insurance Cardiovascular Scholarship. The authors have disclosed no relevant financial relationships.

SGLT2 inhibitor use tied to fewer atrial arrhythmias

Article Type
Changed
Tue, 05/03/2022 - 15:02

Patients with cardiac implantable electronic devices (CIEDs) who received treatment with an sodium-glucose cotransporter 2 inhibitor had significantly fewer atrial arrhythmia events, compared with those who never received such a drug, in a prospective analysis of nearly 14,000 patients with a device who were followed for an average of nearly 2 years.

The findings suggest that use of an agent from the class of SGLT2 inhibitors “is associated with a pronounced reduction in atrial arrhythmia burden and all-cause mortality in patients with a CIED in a real-world setting,” said Ilan Goldenberg, MD, at the American Heart Association scientific sessions. “These data indicate possible antiarrhythmic properties of SGLT2 inhibitors that are incremental to the beneficial effects of the drug on heart failure outcomes,” added Dr. Goldenberg, director of the Clinical Cardiovascular Research Center at the University of Rochester (N.Y.).

In a propensity score–matched analysis that included more than 5,000 of the enrolled patients with a CIED, treatment with an SGLT2 inhibitor was tied to a significant 23% relative reduction in atrial arrhythmia events and a 44% relative drop in all-cause death, he reported.
 

Effect mediated by reduced left atrial pressure?

“Other heart failure drugs have shown some decrease in the rate of sudden cardiac death, but this is the first [heart failure] drug to associate with a reduction in atrial arrhythmias,” Dr. Goldenberg noted. “We think that a reduction in left atrial pressure” produced by treatment with an SGLT2 inhibitor “may be linked to the reduction in atrial arrhythmias.”

The study did not show an association of SGLT2-inhibitor use and a change in ventricular arrhythmias, compared with patients with CIEDs who did not receive an agent from this class.

The findings suggest “expanding the possible indications for SGLT2 inhibitors,” commented Harriette G.C. Van Spall, MD, a cardiologist at McMaster University, Hamilton, Ont., who moderated the session where Dr. Goldenberg gave his report.

The study included 13,890 consecutive, prospectively enrolled patients who received a CIED during January 2015–April 2020 at any of five hospitals operated by either of two tertiary health care systems, one run by the University of Rochester and the second based at Sheba Medical Center in Tel HaShomer, Israel. The devices that made patients eligible for the study included permanent pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy devices, and implantable cardiac monitors. A blinded adjudication committee composed of electrophysiologists identified the arrhythmic episodes.

At entry into the study (the time of device implantation), 12,992 patients were not receiving an SGLT2 inhibitor (94%) and 898 (6%) were receiving a drug from this class. Of those, 39% were on dapagliflozin (Farxiga), 35% were on empagliflozin (Jardiance), and 26% were on canagliflozin (Invokana).

Patients receiving an SGLT2 inhibitor at baseline were on average substantially younger than the patients not on this drug class (59 years vs. 69 years); they had a substantially higher prevalence of diabetes (78% vs. 25%), and ischemic cardiomyopathy (63% vs. 39%). Patients on an SGLT2 inhibitor at baseline also had more modestly higher prevalence rates of prior heart failure (38% vs. 31%), and hypertension (69% vs. 63%). Prevalence of a history of atrial fibrillation (AFib) was nearly the same in both groups: 31% in patients on an SGLT2 inhibitor and 35% in those not on these drugs.

The study’s primary endpoint was the total number of arrhythmia events during follow-up of 24,442 patient-years, during which patients exhibited 19,633 atrial arrhythmia events and 3,231 ventricular arrhythmia events.
 

 

 

1% absolute reduction in atrial arrhythmias

A multivariate analysis of the entire population – adjusted for baseline differences in age, diabetes, sex, and history of AFib – showed that treatment with an SGLT2 inhibitor at baseline was linked with a significant 24% relative reduction in incident atrial arrhythmia events, a significant 24% reduction in both atrial and ventricular arrhythmia events, and a 42% relative reduction in all-cause deaths, compared with no SGLT2-inhibitor treatment.

The only analyzed endpoint that showed no significant between-group difference was incidence of ventricular arrhythmias, which was a relative 7% lower in the SGLT2-inhibitor group.

On an absolute basis, treatment with an SGLT2 inhibitor was tied to about a 1% lower rate of atrial arrhythmia events per year, a reduction from a 2.5% rate in those not on an SGLT2 inhibitor to about a 1.5% rate in those taking this drug class.



A second, confirmatory analysis used propensity score matching to identify 5,323 patients not on an SGLT2 inhibitor at baseline who closely matched the 898 patients on an SGLT2 inhibitor. The multivariate modeling for this analysis also adjusted for age, diabetes, sex, and history of AFib.

The results of these analyses closely matched the calculations that used the entire study population. Relative to patients not on an SGLT2 inhibitor those on a drug from this class had 23% fewer atrial arrhythmias, 44% fewer total death, and 22% fewer atrial or ventricular arrhythmias, all significant differences. However, ventricular arrhythmias only reduced by a relative 5%, a nonsignificant difference.

In the propensity score–matched analysis, the absolute reduction in atrial arrhythmias in those on an SGLT2 inhibitor at baseline was roughly 1.3% fewer per year, compared with those not on this drug class.

The study was funded by an unrestricted grant to the University of Rochester from AstraZeneca, the company that markets the SGLT2 inhibitor dapagliflozin (Farxiga). Dr. Goldenberg and Dr. Van Spall had no disclosures.

FDA flags cardiac perforation risks during leadless pacemaker implantation

Article Type

Thu, 11/18/2021 - 13:39

The Food and Drug Administration is reminding health care providers about the risk of major complications if cardiac perforation occurs during leadless pacemaker implantation.

Cardiac perforation is a rare complication and the overall risk associated with leadless pacemaker implantation appears similar to that with traditional transvenous pacemakers, the agency says. However, premarket clinical studies of the Micra leadless pacemaker (Medtronic) suggested major complications related to cardiac perforation appear to be more severe for those receiving a leadless pacemaker.

“Information from real-world use suggests that cardiac perforations associated with Micra leadless pacemakers are more likely to be associated with serious complications, such as cardiac tamponade or death, than with traditional pacemakers,” the FDA said Nov. 17 in a letter to health care professionals.

“The FDA is bringing this information to your attention as a reminder and to encourage you to report leadless pacemaker cardiac perforations and complications related to perforation to the manufacturer and the FDA,” it notes.

The Micra Transcatheter Pacing System in 2015 was the first leadless pacemaker approved in Europe, and was approved in the United States the following year with a mandated postapproval study to help assess continued safety and efficacy. The Micra device is currently the only approved leadless pacemaker in the United States.

The FDA continues to evaluate outcomes in patients who receive leadless pacing systems and recommends that health care providers discuss the risks and benefits of available pacing system options with patients as part of shared clinical decision-making.

Providers are advised to read and carefully follow the instructions for use and training for Medtronic’s Micra pacemaker.

Any adverse events or suspected adverse events related to the Micra Transcatheter Pacing System or any other pacemaker systems should be reported to the FDA through MedWatch, its adverse-event reporting program.

Exercise reduces arm and shoulder problems after breast cancer surgery

Article Type
Changed
Wed, 01/04/2023 - 16:58

Breast cancer treatment often results in shoulder and arm problems, such as chronic pain, restricted shoulder movement, or lymphedema in the armpit area, limiting quality of life and delaying recovery. However, according to a U.K. study published by The BMJ on Nov. 10, women who exercised shortly after having nonreconstructive breast cancer surgery experienced less pain and regained better shoulder and arm mobility at 1 year than those who did not exercise.

“Hospitals should consider training physiotherapists in the PROSPER program to offer this structured, prescribed exercise program to women undergoing axillary clearance surgery and those having radiotherapy to the axilla,” said lead author Julie Bruce, PhD, a specialist in surgical epidemiology with the University of Warwick, Coventry, England.

Up to one-third of women experience adverse effects to their lymphatic and musculoskeletal systems after breast cancer surgery and radiotherapy targeting the axilla. A study of 2,411 women in Denmark found that pain remained for up to 7 years after breast cancer treatment. U.K. guidelines for the management of breast cancer recommend referral to physical therapy if such problems develop, but the best timing and intensity along with the safety of postoperative exercise remain uncertain. A review of the literature in 2019 found a lack of adequate evidence to support the use of postoperative exercise after breast cancer surgery. Moreover, concerns with such exercise have been reported, such as increased risks of postoperative wound complications and lymphedema.

“The study was conducted to address uncertainty whether early postoperative exercise after women at high risk of shoulder and arm problems after nonreconstructive surgery was safe, clinically, and cost-effective. Previous studies were small, and no large high-quality randomized controlled trials had been undertaken with this patient population in the U.K.,” Dr. Bruce said.

In UK PROSPER, a multicenter, randomized controlled trial, researchers investigated the effects of an exercise program compared with usual care for 392 women (mean age 58) undergoing breast cancer surgery at 17 National Health Service (NHS) cancer centers. The women were randomly assigned to usual care with structured exercise or usual care alone. Structured exercise, introduced 7-10 days postoperatively, consisted of a physical therapy–led exercise program comprising stretching, strengthening, and physical activity, along with behavioral change techniques to support exercise adherence. Two further appointments were offered 1 and 3 months later. Outcomes included upper limb function, as measured by the Disability of Arm, Hand, and Shoulder (DASH) questionnaire at 12 months, complications, health related quality of life, and cost effectiveness.

At 12 months, women in the exercise group showed improved upper limb function compared with those who received usual care (mean DASH 16.3 for exercise, 23.7 for usual care; adjusted mean difference 7.81, 95% confidence interval, 3.17-12.44; P = .001). Compared with the usual care group, women in the exercise group reported lower pain intensity, fewer arm disability symptoms, and better health related quality of life.

“We found that arm function, measured using the DASH scale, improved over time and found surprisingly, these differences between treatment groups persisted at 12 months,” Dr. Bruce said. “There was no increased risk of neuropathic pain or lymphedema, so we concluded that the structured exercise program introduced from the seventh postoperative day was safe. Strengthening exercises were introduced from 1 month postoperatively.”

While the authors noted that the study was limited as participants and physical therapists knew which treatment they were receiving, they stressed that the study included a larger sample size than that of previous trials, along with a long follow-up period.

“We know that some women develop late lymphedema. Our findings are based on follow-up at 12 months. We hope to undertake longer-term follow up of our patient sample in the future,” Dr. Bruce said.

The authors declared support from the UK National Institute for Health Research (NIHR) Technology Assessment Programme.

At 12 months, women in the exercise group showed improved upper limb function compared with those who received usual care (mean DASH 16.3 for exercise, 23.7 for usual care; adjusted mean difference 7.81, 95% confidence interval, 3.17-12.44; P = .001). Compared with the usual care group, women in the exercise group reported lower pain intensity, fewer arm disability symptoms, and better health related quality of life.

“We found that arm function, measured using the DASH scale, improved over time and found surprisingly, these differences between treatment groups persisted at 12 months,” Dr. Bruce said. “There was no increased risk of neuropathic pain or lymphedema, so we concluded that the structured exercise program introduced from the seventh postoperative day was safe. Strengthening exercises were introduced from 1 month postoperatively.”

While the authors noted that the study was limited as participants and physical therapists knew which treatment they were receiving, they stressed that the study included a larger sample size than that of previous trials, along with a long follow-up period.

“We know that some women develop late lymphedema. Our findings are based on follow-up at 12 months. We hope to undertake longer-term follow up of our patient sample in the future,” Dr. Bruce said.

The authors declared support from the UK National Institute for Health Research (NIHR) Technology Assessment Programme.
