Watchdog group calls out risks associated with private equity in cardiology, other specialties – Cardiovascular Business

Lets call out private equitys abuse for what it is: legal looting, she said. The Private Equity Stakeholder Projects new state risk index is a razor-sharp tool in the fight to hold private equity accountable. Together, were taking on this trillion-dollar, behemoth industry thats hurting working people and sucking money out of the rest of the economy.

By providing transparent data on the risks associated with private equity investments, we empower communities, working families, and policymakers to advocate for change and protect their states from the threats posed by unchecked private equity firms, added Chris Noble, PESP policy director. This is an important step toward mitigating the risk and tangible harms wrought by private equity across the county.

The rise of PE continues to be one of the biggest trends in all of healthcare, and its presence in cardiology seems to be growing by the day. Cardiovascular Associates of America, Cardiovascular Logistics and other PE-backed cardiology management groups are acquiring more and more practices, and the trend has shown no signs of slowing down.

A recent survey found that a majority of physicians have a negative opinion about the rise of PE in cardiology, radiology and other healthcare specialties. Just last month, thousands of U.S. physicians united to launch a new Coalition for Patient-Centered Care.

In addition, the increasing influence of PE was one of the biggest topics at ACC.24, the annual meeting of the American College of Cardiology (ACC). ACC.24 focused on the business of cardiology much more than previous ACC meetings, in part as a response to ongoing trends cardiologists are witnessing throughout the country.

TAVR Found Non-Inferior to SAVR for Low-Risk Patients – Diagnostic and Interventional Cardiology

April 11, 2024 Transcatheter aortic valve replacement (TAVR) was found to bring no increased risks and was associated with substantial decreased rates of death or stroke at one year in lowrisk patients, compared with surgical aortic valve replacement (SAVR), according to findings presented at the American College of Cardiologys Annual Scientific Session.

TAVR and SAVR are procedures to replace a damaged aortic valve that is not functioning properly. U.S. guidelines recommend TAVR, a catheter-based approach in which the new valve is threaded to the heart through a blood vessel in the groin or chest, over open-heart SAVR for older patients and those with high cardiovascular risk. However, previous studies and different countries guidelines have varied when it comes to determining the optimal approach for younger and lower-risk patients.

We can now provide strong data that in this low-risk patient population, you could very safely offer TAVR vs. SAVR, said Moritz Seiffert, MD, professor of cardiology at BG University Hospital Bergmannsheil, Ruhr University Bochum in Bochum, Germany, and one of the study authors. TAVR is less invasive; its usually performed under local anesthesia, lasting 30-60 minutes, and the convalescence is shorter than with open chest surgery. [These findings offer] a strong argument toward catheter-based treatment, at least for the one-year timeframe of this study, in these patients.

The DEDICATE-DZHK6 trial compared TAVR vs. SAVR in 1,414 patients who underwent valve replacement procedures at 38 centers in Germany.

All patients enrolled in the trial were eligible for either TAVR or SAVR and had similar characteristics in terms of the severity of aortic stenosis (narrowing of the valve which makes it harder for blood to flow efficiently) and a similar balance of risks and benefits expected with either type of procedure. Patients with bicuspid valves, previous heart surgery or additional coronary or valvular diseases requiring further treatment were excluded. The average age of participants was 74 years and 43% were women.

Researchers randomly assigned half of the participants to undergo TAVR and the other half to SAVR. Since the trial was intended to mirror real-world conditions, many decisions were left to the local heart teams at each study site, rather than strict predetermined study protocols. Local interdisciplinary heart teams determined which patients were eligible to participate in the study based on broad inclusion criteria. Operators selected which replacement valve to use and followed their own centers standard practices for performing the procedures.

The co-primary safety endpoint was designed to assess whether TAVR was non-inferior to SAVR as indicated by an absolute increase of no more than 1% in the composite rate of death or stroke at one year. The trial met this endpoint, showing that people who underwent TAVR were 47% less likely than those undergoing SAVR to experience death or stroke at one year. Event rates for several secondary endpoints, including all-cause death or disabling stroke, were also significantly lower in patients undergoing TAVR compared with those undergoing SAVR at one year.

Although we primarily tested for non-inferiority, the magnitude of the difference surprised us, Seiffert said. Valve prosthesis selection based on individual patients anatomical and medical considerations may have played a role. In addition, the COVID-19 pandemic might have amplified the surgical risk. In fact, the relative difference was comparable to previous studies, but the overall higher event rates and larger patient population may have led to these significant results.

Researchers plan to further investigate some factors that set the trial apart from previous studies and may have contributed to the substantially reduced risk in the TAVR group, including the relatively high proportion of females in the study group. The data were consistent among the subgroups tested so far.

Overall, researchers said that the findings are likely generalizable to patient populations and health care environments across many developed countries.

What it really adds to previous trials is that it mirrors clinical routine, Seiffert said. Its completely industry independent, not focused on one particular device but comparing a catheter-based strategy to a surgical strategy overall. That makes it more applicable and aligned with the types of decisions physicians are making in their daily medical work.

The researchers will continue to track outcomes for at least five years. Future analyses will include additional metrics for assessing clinical superiority as well as quality of life outcomes. In addition, researchers plan to examine whether certain subgroups appear to derive specific risks or benefits from one approach or the other.

The study was funded by German Center for Cardiovascular Research with financial support by the German Heart Foundation. This study was simultaneously published online in the New England Journal of Medicine at the time of presentation.

Telemedicine Strategy After MI Scores a Win in TELE-ACS – TCTMD

ATLANTA, GAA telemedicine-based approach to care after acute coronary syndromes can reduce readmissions to the hospital, visits to the emergency department (ED), and the rates of stroke and MI, according to results from the randomized TELE-ACS trial. Notably, use of the management strategy also was linked a reduction in patient-reported symptoms.

MI remains one of the leading causes of mortality in the UK despite cutting-edge medical and interventional therapies, said Nasser S. Alshahrani, MSc (Imperial College London, England, and King Khalid University, Abha, Saudi Arabia), presenting the data at the recent American College of Cardiology (ACC) 2024 Scientific Session. Moreover, around 10% of patients return to the hospital within 30 days of their event.

TELE-ACS, said Alshahrani, was designed to see if a novel telemonitoring system-based algorithm would reduce hospital readmissions for patients post-ACS by using well-validated technologies coupled with an urgent remote consultation with a cardiologist.

One question at the outset was whether the remote monitoring would provide enough information to guarantee clinicians could effectively assess patients without necessitating a face-to-face encounter, he said. The results, simultaneously published in the Journal of the American College of Cardiology, suggest the answer to that is yes.

ACC President Cathleen Biga, MSN, RN (Cardiovascular Management of Illinois, Woodridge), said she was struck by this trial and others at the meeting that focused on transformation of care delivery. So much of medicine has evolved, yet our quality hasnt gotten better, Biga commented. We have got to figure out a different way of caring for our patients because our MI readmission rate, our 30-day mortality after an acute coronary syndrome, the needle isnt moving. So what are we going to do differently to help move that needle?

Biga said the TELE-ACS trial speaks to the possibilities that a remote approach could continue to offer MI patients in todays practice.

The COVID-19 pandemic abruptly upended care back in 2020, Biga pointed out. We went completely telehealth in 12 hours, . . . before we opened our office that Monday. We changed in a nanosecond. Then, as the world grew more used to the virus, we went right back to packed waiting rooms [and] in-person visits, she noted.

Telemedicine vs Usual Care

Alshahrani and colleagues analyzed data for 337 patients (mean age 58.1 years; 86% male; 46% white) with at least one cardiovascular risk factor who had been hospitalized with ACS between January 2022 and April 2023. Three-quarters had hypercholesterolemia, nearly 60% were smokers or had a history of smoking, around half had hypertension, four in 10 had a family history of CAD, and a little more than a quarter had diabetes.

Prior to discharge, the patients were randomized to receive either telemedicine-based or standard care; to participate, they had to have access to a smartphone or other smart device.

In the intervention group, patients received a telemonitoring package consisting of a 12-lead ECG belt (SHL SmartHeart; SHL Telemedicine), an automated blood-pressure monitor (Omron Basic M2; Omron Corporation), and a pulse oximeter (Kinetik Wellbeing), as well as training in how to use the devices. They also received follow-up phone calls for training at 2, 4, and 8 weeks.

When these patients felt symptoms they thought were potentially cardiac, they used their telemonitoring tools, with the details transmitted to a cardiologist. The cardiologist performed remote clinical assessment and then triaged patients to receive either reassurance with clinical follow-up as previously planned or advice to contact their general practitioner, go to the ED for further testing, or call emergency services. Cardiologists based their decision-making on an algorithm that categorized symptoms and clinical parameters. Remote consultations were available from 7 AM to 11 PM on weekdays; outside of these time frames, or if they didnt hear from a cardiologist within 15 minutes of reporting their symptoms, patients were meant to seek medical advice through the usual clinical pathways.

In the control arm, patients sought medical advice through the usual pathways and received standard routine clinical care, with remote, phone-based follow-up at 3, 6, and 9 months.

We have got to figure out a different way of caring for our patients, because . . . the needle isnt moving. Cathleen Biga

Study participants made a total of 169 calls, 64% of them during the active hours on weekdays. Reported symptoms were most often chest pain/discomfort, followed by palpitations and general weakness.

Of the 108 calls during the active hours, 54.6% resulted in patients receiving reassurance. Another 26.9% were advised to visit their general practitioner, 13.9% told to visit the ED, and 4.62% recommended to call emergency services.

By 6-month follow-up, there were 20 readmissions with telemedicine and 50 with standard care. Thus, the time to readmission (primary endpoint) was reduced with the remote strategy, as were visits to the ED and MIs. Stroke trended lower, though the rate of all-cause death was identical in the two groups.

Moreover, patients in the telemedicine group had fewer unplanned coronary revascularizations than did controls (3% vs 9%) and were less likely to report chest pain (9% vs 24%), breathlessness (21% vs 39%), and dizziness (6% vs 18%).

Telemonitoring in the active study arm ceased at 6 months. Notably, though, the initial effect between 0 to 6 [months] was large enough to leave a legacy effect up to 9 months, Alshahrani said.

At 9-month follow-up, hospital readmissions still were less common with the intervention than with usual care (HR 0.35; 95% CI 0.21-0.59). So, too, were visits to the emergency department (HR 0.66; 95% CI 0.46-0.94) and the rate of invasive coronary angiography and/or angioplasty (4% vs 10%; P= 0.03). However, there was no longer a difference in symptoms between the two groups.

Alshahrani, in his presentation, cited several limitations to their study. Among them were its predominately male population, the potential for recall bias due to retrospective collection of symptom data, and the fact that participants were required to have access to a smartphone.

Additionally, the high level of support for the telemedicine group, with prompt cardiology responses, may be challenging to replicate outside a trial setting, requiring significant investment and training, he continued, while technological barriers and infrastructure requirements may pose some obstacles to implementation. . . . Further studies need to establish the feasibility of implementation in different healthcare systems.

We were surprised by the large effect. Nasser S. Alshahrani

Malissa Wood, MD (Lee Health Heart Institute, Fort Myers, FL), discussant for the TELE-ACS results, highlighted the decrease in MI with monitoring. Do you think the intervention was related to that, as far as the patients knowing that they were being monitored or that they could reach out to someone? Did you look at any psychosocial variables to see if that reduced stress, anxiety, or depression in that population that may have been related to that reduction in myocardial infarction?

We were surprised by the large effect, and it could be because of the high level of support that we delivered and also the patient education on symptoms at the point of contact and then at regular intervals thereafter, Alshahrani explained. It could be the Hawthorne effect: when the patient is monitored, they tend to change their behavior.

For ease of use, Wood suggested that going forward it would be good to have a device that incorporates all three measurementsoxygen saturation, blood pressure, and ECG readingsso you dont have the patient having to [use] all these different devices to transmit data.

Biga, speaking with TCTMD, said that much of the positive impact in TELE-ACS may come from the fact that telemedicine offered a way to connect regularly with a human touch, albeit remote, that was reassuring but also offered practical advice and constant education. This can be valuable for patients feeling overwhelmed by the intricacies of their care after discharge, she said.

As Biga noted, the challenge lies in how to implement the strategy. Patients may prefer to call their own doctors office over a less-familiar hotline, and any added personnel or other resources to handle these calls must be paid for. The most convenient, cost-effective option going forward might be third-party companies to streamline remote monitoring, she added, so the practices dont carry the burden, because the payment from [Medicare for] remote patient monitoring isnt going to begin to cover the cost of that: you have the equipment and the intellectual property.

Scaling up is tricky, especially with the tsunami of data, Biga stressed. In just one of her practices, Biga said, 900 patients are seen a daymore than five times the number of participants in the intervention arm of TELE-ACS. The real-world math is daunting, she pointed out. How many MIs do I have a month? Can I get them all hooked up and compliant and have the staff to analyze that data?

Impact of Interatrial Shunt May Vary by Heart Failure Type – Diagnostic and Interventional Cardiology

April 6, 2024 Patients with heart failure who had a small shunt inserted between the hearts left and right atria did not see any significant benefits overall compared with those who received a placebo procedure after a median of 22 months follow-up, in a study presented at the American College of Cardiologys Annual Scientific Session.

The trial, called RELIEVE-HF, is the first randomized placebo-procedure controlled trial of interatrial shunting that included patients with both major types of heart failure: heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). While the trial did not meet its primary endpoint, it moves the field forward by offering signals that the benefits and risks of interatrial shunts may vary by heart failure type, according to researchers.

Gregg Stone, MD

When you examine the outcomes in patients with heart failure across a broad range of left ventricular ejection fraction, the Ventura interatrial shunt was extremely safe but did not improve outcomes compared with no treatment. However, in a prespecified analysis, data suggest that the shunt may be beneficial in patients with HFrEF and worsen outcomes in patients with HFpEF, said Gregg Stone, MD, professor of cardiology and population health sciences at Icahn School of Medicine at Mount Sinai in New York and the studys first author. We believe further studies are warranted to confirm the benefits we observed in patients with reduced ejection fraction.

Heart failure is a condition in which the heart becomes too weak or stiff to effectively pump blood, leading to fatigue, organ damage, shortness of breath and an increased risk of life-threatening cardiovascular events. In HFrEF, the heart muscle becomes weak and does not squeeze as hard as it should. In HFpEF, the left ventricle becomes stiff and does not properly fill with blood.

The Ventura shunt is one of several interatrial devices being tested to aid in the treatment of heart failure. It is designed to form a small connection or passage between the left and right atria to allow blood to leave the left atriumespecially as left atrial pressure risesthus reducing the pressure in the left atrium and the lungs. High left atrial pressure is a primary cause of shortness of breath and hospitalizations related to heart failure.

The trial randomized 508 patients at 94 sites in North America, Europe, Israel, Australia and New Zealand. All participants had symptomatic heart failure despite taking medications at maximally tolerated doses. About 40% of participants had HFrEF and 60% had HFpEF.

Participants were randomly assigned to undergo a procedure to insert the Ventura shunt or a placebo procedure in which a script was followed with all the same protocols to mask patients as to whether the shunt was inserted. Operators were aware of which procedure each patient received but patients, their families and the rest of the medical teams taking care of the patient after the procedure were not. Researchers tracked outcomes in each participant for at least one year and up to two years.

The results showed no significant difference between groups in terms of the trials primary endpoint, a hierarchical composite ranking of death from any cause; heart transplant or left ventricular assist device; heart failure hospitalizations; worsening of outpatient heart failure events; and change in quality of life, as measured using the Kansas City Cardiomyopathy Questionnaire (KCCQ). This hierarchical composite approach for assessing efficacy allows diverse types of outcomes to be incorporated in ranked fashion into an overall win ratio reflecting the overall outcome of a drug or device.

In a pre-planned analysis focused on heart failure type, patients with HFrEF who received the shunt were found to have improvements across all outcomes assessed (especially fewer hospitalizations for heart failure), while those with HFpEF who received the shunt were found to have increased rates of death and heart failure hospitalizations. This difference could be attributed to the greater compliance or flexibility of the heart muscle with HFrEF, potentially allowing it to more easily accommodate the extra blood flowing into the right atrium, Stone said.

There were no device-related or procedure-related major adverse cardiovascular or neurologic events in either group during the duration of the trial.

Surprisingly, a marked improvement in quality of life as measured with KCCQ was observed across all groupsincluding those who received a placebo procedure, both with HFrEF and HFpEFsuggesting that the metric may not be a reliable indicator for quality-of-life outcomes in this context, Stone said.

There was a tremendous placebo effect, he said. These observations, especially the fact that quality of life improved in HFpEF patients who were more likely to be hospitalized for heart failure and had reduced survival after shunt treatment, raise questions about the interpretation of this quality-of-life measure in these kinds of trials.

Although the observed differences in outcomes among people with different types of heart failure may inform future research and development for interatrial devices, the researchers said that the trial was not powered to show differences in the two types of heart failure. As such, these results should be considered exploratory. They also said that the results may not be applicable to other interatrial shunts beyond the Ventura shunt.

The study was funded by V-Wave Medical.

SGLT-2 Inhibitors Show Mixed Results After Heart Attack – Diagnostic and Interventional Cardiology

April 6, 2024 Use of the sodium glucose cotransporter-2 (SGLT-2) inhibitor empagliflozin following a heart attack did not show a significant benefit in reducing overall heart failure hospitalizations or death from any cause, according to a study presented at the American College of Cardiologys Annual Scientific Session. However, researchers said the drug may be helpful in reducing heart failure risks, including hospitalization, following a heart attack.

Javed Butler, MD

Despite falling short of its primary endpoint, results from the EMPACT-MI trial found that people who took empagliflozin had a significantly lower risk of certain outcomes directly related to heart failure, including first hospitalization for heart failure, total hospitalization for heart failure and a composite of heart failure hospitalization and death from heart failure, without any increased risk of adverse events.

We found that empagliflozin did not reduce mortality after a heart attack but did reduce the risk of heart failure after heart attack, said Javed Butler, MD, president of the Baylor Scott and White Research Institute in Dallas, distinguished professor of medicine at the University of Mississippi in Jackson, Mississippi, and the studys lead author. To have a 25% to 30% reduction in heart failure hospitalizations is pretty clinically meaningful, but if you put it together with all-cause mortality, it was not a positive study for our primary endpoint.

SGLT-2 inhibitors were initially approved to treat Type 2 diabetes by lowering blood sugar. As evidence has mounted pointing to their benefits in reducing heart failure and other forms of heart disease, researchers have sought to determine whether these drugs could help to prevent heart failure even in people without diabetes or chronic kidney disease.

A heart attack can damage the heart muscle in ways that sometimes lead to heart failure, a condition in which the heart becomes too weak or too stiff to effectively pump blood throughout the body. The EMPACT-MI trial was designed to determine whether SGLT-2 inhibitors could safely help to prevent heart failure and reduce mortality in people with a high risk of heart failure following a heart attack.

The study enrolled 6,522 people treated for acute myocardial infarction at 451 centers in 22 countries. Participants had no history of heart failure but had at least one heart failure risk factor in addition to signs of potential heart dysfunction as indicated by a newly lowered left ventricle ejection fraction to below45% and/or signs or symptoms of congestion requiring treatment. About 32% had Type 2 diabetes. On average, participants were 64 years old and approximately 25% were women and 84% were White. Within 14 days of being admitted to the hospital for a heart attack, half of the participants were randomly assigned to receive empagliflozin at a dose of 10 mg daily, while the other half received a placebo. Researchers tracked outcomes for a median of just under 18 months.

The studys primary composite endpoint occurred in 8.2% of those who received empagliflozin and 9.1% of those receiving a placebo, a difference that was not statistically significant. There was also no difference in the rate of death from any cause, which occurred in 5.2% of those receiving empagliflozin and 5.5% of the control group.

All secondary endpoints related specifically to heart failure outcomes were significantly reduced among patients who received empagliflozin. For example, those receiving empagliflozin were 23% less likely to experience a first heart failure hospitalization and 33% less likely to experience any heart failure hospitalizationincluding recurrent hospitalizationscompared with those taking a placebo. The composite rate of total heart failure hospitalizations and death from heart failure was also 31% lower among those receiving empagliflozin.

Among patients who were not taking common heart failure therapies such as diuretics, angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor/neprilysin inhibitor (ARNI) at the time of their initial hospital discharge, those taking empagliflozin were significantly less likely to start such therapies within six months compared with those taking a placebo.

In terms of heart failure outcomes, the data is not only strong, but its consistent with what weve found over the past 10 years in yet another population, Butler said. This finding is completely consistent in both direction and magnitude with other studies of SGLT-2 inhibitors in populations with diabetes and chronic kidney disease.

While as a pragmatic trial design to simplify trial procedures and make it easier on both the participants and the sites, the study had limitations that may have influenced the findings, researchers said. For example, because outcomes were not adjudicated by independent reviewers, outpatient heart failure events were not formally captured as part of the primary endpoint. However, researchers said data on outpatient heart failure visits were collected as part of the study protocols for assessing adverse events. An analysis of these events showed outpatient visits for heart failure were substantially lower in participants who received empagliflozin compared with placebo.

Another limitation was the use of all-cause mortality as part of the primary endpoint, which meant that deaths unrelated to heart failure were included in the endpoint even though the study drug was unlikely to influence them. There were also some unusual circumstances that may have influenced rates of both hospitalization and death, including the COVID-19 pandemic and conflicts involving Russia, Ukraine and Israel, all countries that participated in the trial.

Finally, researchers said that the follow-up period may have been too short to fully capture any difference in mortality related to heart failure. Since people who developed heart failure following their heart attack typically did not begin to show heart failure symptoms until a few months later, any reductions in mortality would not be expected to emerge until after that.

We just did not have long enough follow-up to see whether that heart failure prevention would lead to a benefit in mortality, but its a reasonable clinical thing to say that if youre preventing heart failure, its a good thing, Butler said.

The study was funded by Boehringer Ingelheim and Eli Lilly.

This study was simultaneously published online in the New England Journal of Medicine at the time of presentation.

Butler presented the study, Empagliflozin After Acute Myocardial Infarction: Results of the EMPACTMI Trial, on day one of the 3-day ACC.24 conference.
