Stem cell therapy for STEMI falls short at 2 years

Article Type
Changed

 

– Longer follow-up has not altered initial negative findings of the randomized phase II TIME trial, which tested the efficacy of early intracoronary stem cell therapy, given on day 3 or 7 after an ST-segment acute MI (STEMI). However, loss of the sickest patients from follow-up may have influenced the findings.

“When TIME (Transplantation in Myocardial Infarction Evaluation) was developed several years ago, the optimal timing for cell delivery following myocardial infarction was not known and had not been directly tested in a prospective clinical trial,” explained lead investigator Jay H. Traverse, MD, director of research at the Minneapolis Heart Institute Foundation and a senior consulting cardiologist at the Abbott Northwestern Hospital, Minneapolis.

Dr. Jay H. Traverse
Results at 6 months among the 120 randomized patients showed improvements but no significant differences between the trial’s cell therapy and placebo groups with respect to measures of global and regional left ventricular (LV) function on cardiac MRI, he recapped at the American Heart Association scientific sessions.

With the new, additional follow-up out to 2 years in 85 patients, both groups saw further gains in LV ejection fraction and further reductions in LV infarct size, as well as stable LV end-diastolic volume index, but still with no significant differences between them.

Of note, however, 10 of the patients lost to follow-up were lost because they received implantable cardioverter defibrillators (ICDs) and, given technologic limitations at the time, could no longer undergo cardiac MRI, Dr. Traverse noted. “These 10 patients are important as we look at the long-term follow-up of TIME because these patients were more likely to have the most severe LV dysfunction and most remodeled left ventricles. This [subset] represents a limitation to long-term follow-up studies in this population.”

Challenges to research

Two challenging issues seen in many trials of cell therapy for cardiovascular disease are their underpowered nature and the changing natural history of the disease, according to session comoderator Timothy D. Henry, MD, head of cardiology at Cedars-Sinai in Los Angeles.

“One of the things with the TIME trial that’s striking, really, is that even though these are high-risk patients, there was almost no mortality in 2 years,” he commented. “Second of all... there were no differences in ejection fraction, but that’s because you are missing 30% of people. And your missing 30% of people are the sick people, so of course if you are just going to follow normal people for 2 years, you’re going to have normal results.”

“What you are seeing is a little bit illusory because all the sick patients got ICDs and we could no longer image them at that time,” Dr. Traverse agreed. “That will be less of an issue in some of our future trials that we have started now, like CONCERT and SENECA, where we are now able to do MRI analysis of people with devices. So that will certainly help.”

Nonetheless, all trials in similar patient populations are plagued by substantial rates of dropout over time and faced with improving outcomes generally, because of better medical therapy, he acknowledged. “You can see as far as the natural history, even taking into account the ICD changes that would have lowered volumes, people are pretty stable on medical therapy. Their ejection fractions and volumes out to 2 years were really quite stable. We have certainly impacted that.”

That issue raises the question of whether investigators should be using other endpoints going forward, according to session panelist Doris A. Taylor, PhD, director of Regenerative Medicine Research at the Texas Heart Institute in Houston.

“One of the things I’ve seen over and over in this field is constantly evolving questions about which endpoints we should follow and what constitutes positive effects,” she commented. “So given the natural history, what are the endpoints we should be using?”

“Patients don’t care what their ejection fraction is per se. But they want to know if they have to get an ICD or if they will be hospitalized for heart failure, and their family is affected if they die,” Dr. Traverse replied. “We definitely need these hard endpoints. The problem is that you need so many patients with these hard endpoints that [the trials] are just financially not very doable. So that’s a big issue.”

Trial details

Patients enrolled in TIME had a first anterior STEMI, underwent reperfusion by angioplasty and stenting, and had LV dysfunction with an ejection fraction of 45% or lower. They all received either autologous bone marrow mononuclear cells or placebo on day 3 or day 7 after their MI by intracoronary infusion.

 

 

Of the initial 120 randomized patients, 10 patients were lost to follow-up because of receipt of an ICD, 3 had died (1 each from cardiovascular causes, pancreatitis, and hemorrhagic stroke), 7 were lost to follow-up for other reasons, and 15 had acquired other contraindications to MRI, according to Dr. Traverse.

At 2 years, the remaining patients in both the cell therapy and placebo groups had roughly 5% absolute increases in LV ejection fraction from baseline and roughly 45% reductions in infarct size from baseline, with no significant differences between groups.

When all patients were combined, about half were determined to have had microvascular obstruction at baseline. This finding was an adverse prognostic factor, associated with poorer recovery of LV function over time, greater adverse LV remodeling, and a higher likelihood of receiving an ICD, Dr. Traverse reported.

He has received a research grant from the National Heart, Lung, and Blood Institute, which sponsored the TIME trial.

Diabetes treatment costs doubled in Sweden since 2006

Article Type

– Sweden has experienced a doubling in its national costs for treating type 2 diabetes from €608 million in 2006 to €1.27 billion in 2014.

The increase is directly related to a surge of more than 100,000 in the number of patients with the disease and has been driven by increased hospitalizations for cardiovascular complications of diabetes, Almina Kalkan, PhD, reported at the annual meeting of the European Association for the Study of Diabetes.

Dr. Almina Kalkan
The number of people being treated for type 2 diabetes jumped from 206,000 in 2006 to 366,500 in 2014, a 78% increase, said Dr. Kalkan, a health economist with AstraZeneca in Stockholm.

Costs jumped on a per-patient level as well, but the increase wasn’t related to diabetes treatment – in fact, antidiabetic medication costs remained stable at 4% over the entire study period. The real driver was the cost of treating heart failure and stroke, which increased by 92% and 73%, respectively, over the study period.
 

“You can really see that preventing these diabetes complications is of major importance, not only for patient quality of life but for reducing health care expenditures,” said Dr. Kalkan.

She and her colleagues searched the Swedish Prescribed Drug Registry to identify patients treated for type 2 diabetes, and linked those patients with annual hospital admissions, discharges, and hospital outpatient visits in the National Patient Register. This database doesn’t contain information on primary care visits, so this was imputed from prior studies, as were data on lost work productivity due to the disease.

According to national records, 206,183 Swedish citizens were treated for type 2 diabetes in 2006; by 2014, that number was 366,492. The mean patient age was unchanged (67 years). There was a significant increase of 2% in the number of patients who had cardiovascular disease (33%-35%). That was driven by increases in heart failure and atrial fibrillation; the proportion with myocardial infarction and stroke was unchanged.

Significantly more patients also had kidney disease by 2014 (1.5%-3.2%), although macrovascular disease had decreased by 4%. Lower limb amputations increased as well.

In the overall analysis, inpatient hospital visits accounted for the bulk of the spending, rising from €355 million in 2006 to €783 million in 2014. This was followed by spending on outpatient hospital care (from €112 million to €303 million). Spending on diabetes medications went from €39 million to €84 million, but the increase stayed proportional at just over 6%.

The total annual cost per patient increased as well, from just under €3,000/year to €3,500/year – an 18% increase.

“We still see that the main driver was inpatient and outpatient hospital care,“ Dr. Kalkan said. “Total inpatient costs increased by 24% per patient, and total outpatient costs increased by 52%.”

The proportion spent on inpatient and outpatient hospital care for each patient increased from 77% to 85% of total expenditures. Again, there was no change in the cost of diabetes medications or in the proportion of costs spent on such drugs.

Dr. Kalkan and her colleagues then conducted a societal cost analysis, which included data on primary care visits and lost job productivity related to diabetes. There was an overall 22% increase in national cost during the study period, rising from €4,200 to €5,300/patient-year.

“Inpatient visits increased by 72%, although length of stay decreased, from 13 to 11 days,” Dr. Kalkan said. “Despite this, the costs proportionately increased. This was directly due to the cost of treating the most common cardiovascular comorbidities of diabetes: heart failure, chest pain, myocardial infarction, and stroke.”

In this analysis, the cost of antidiabetic drugs was also quite small and remained stable, at 4% over the entire study period.

The cost of lost productivity was drawn from a 2015 report issued by the Swedish Institute for Health Economics. This report found that type 2 diabetes was related to a net per patient loss of €206/year in 2006 and €317/year in 2014 – a significant change.

The cost analysis was a collaborative project of AstraZeneca, Uppsala University, and the Karolinksa Institute. Dr. Kalkan is an employee of AstraZeneca.

Dementia prevalence increased in heart failure patients

NEW ORLEANS– Elderly patients with heart failure had a significantly increased prevalence of both dementia and mild cognitive impairment, compared with similar people without heart failure, in an analysis of data collected from more than 6,000 U.S. residents enrolled in a long-term observational study.

Patients diagnosed with either heart failure with reduced ejection fraction or heart failure with preserved ejection fraction had an 89% increased prevalence of dementia and a 41% increased prevalence of mild cognitive impairment (MCI), compared with people from the same cohort who did not develop heart failure, in an analysis that adjusted for several demographic and clinical variables, Lucy S. Witt, MD, reported at the American Heart Association scientific sessions. She speculated that the link between heart failure and dementia and MCI might result from impaired cerebral perfusion in heart failure patients or from effects from heart failure medications.

“Our findings suggest that clinicians should have a higher suspicion for cognitive impairment in patients with heart failure, regardless of other, more classic risk factors,” she said in an interview. “This knowledge could prompt physicians to perform testing [for dementia and MCI], initiate conversations regarding the goals of care or advance care planning, and discuss appropriate living situations” for their patients with heart failure, said Dr. Witt, a researcher at the University of North Carolina in Chapel Hill.

The analysis used data collected for the Atherosclerosis Risk in Communities (ARIC) study, which began in 1987 and enrolled a randomly selected representative cohort of nearly 16,000 women and men aged 45-64 years old who resided in any of four U.S. communities. She specifically focused on the data collected from 6,431 of the participants who returned for a fifth follow-up examination during 2011-2013, including 5,490 people without heart failure, whose average age was 76 years, and 941 participants with heart failure, whose average age was 78 years.

Dementia prevalence at the fifth follow-up visit occurred at an adjusted rate of 5.6% among those without heart failure and 7.0% in those with heart failure. The examinations also found MCI in an adjusted 21.5% of those without heart failure and in 26.2% of those with heart failure, Dr. Witt reported. Adjustments included age, sex, location, education, hypertension, diabetes, depression, alcohol and tobacco use, cerebral vascular disease, marital status, and several other factors.

The relative risk for having dementia among the heart failure patients was roughly similar, regardless of whether ARIC participants with heart failure had a reduced or preserved left ventricular ejection fraction, she said.

ARIC is funded by the National Heart, Lung, and Blood Institute. Dr. Witt had no disclosures.

She speculated that the link between heart failure and dementia and MCI might result from impaired cerebral perfusion in heart failure patients or from effects from heart failure medications.

“Our findings suggest that clinicians should have a higher suspicion for cognitive impairment in patients with heart failure, regardless of other, more classic risk factors,” she said in an interview. “This knowledge could prompt physicians to perform testing [for dementia and MCI], initiate conversations regarding the goals of care or advance care planning, and discuss appropriate living situations” for their patients with heart failure, said Dr. Witt, a researcher at the University of North Carolina in Chapel Hill.

The analysis used data collected for the Atherosclerosis Risk in Communities (ARIC) study, which began in 1987 and enrolled a randomly selected representative cohort of nearly 16,000 women and men aged 45-64 years old who resided in any of four U.S. communities. She specifically focused on the data collected from 6,431 of the participants who returned for a fifth follow-up examination during 2011-2013, including 5,490 people without heart failure, whose average age was 76 years, and 941 participants with heart failure, whose average age was 78 years.

Dementia prevalence at the fifth follow-up visit occurred at an adjusted rate of 5.6% among those without heart failure and 7.0% in those with heart failure. The examinations also found MCI in an adjusted 21.5% of those without heart failure and in 26.2% of those with heart failure, Dr. Witt reported. Adjustments included age, sex, location, education, hypertension, diabetes, depression, alcohol and tobacco use, cerebral vascular disease, marital status, and several other factors.

The relative risk for having dementia among the heart failure patients was roughly similar, regardless of whether ARIC participants with heart failure had a reduced or preserved left ventricular ejection fraction, she said.

NEW ORLEANS– Elderly patients with heart failure had a significantly increased prevalence of both dementia and mild cognitive impairment, compared with similar people without heart failure, in an analysis of data collected from more than 6,000 U.S. residents enrolled in a long-term observational study.

Patients diagnosed with either heart failure with reduced ejection fraction or heart failure with preserved ejection fraction had an 89% increased prevalence of dementia and a 41% increased prevalence of mild cognitive impairment (MCI), compared with people from the same cohort who did not develop heart failure, in an analysis that adjusted for several demographic and clinical variables, Lucy S.

Observational hospital stays for HF linked to worse outcomes

– The Centers for Medicare & Medicaid Services policy providing financial incentives for hospitals to readmit patients for heart failure for an observational stay rather than as an inpatient is antithetical to the patients’ best interests, according to data presented at the American Heart Association scientific sessions.

“We showed that if you get admitted under observation, the risk of you coming back is much higher than if you’re under an inpatient stay,” said Ahmad Masri, MBBS, of the University of Pittsburgh.

CMS doesn’t impose financial penalties on hospitals for readmission of heart failure patients under observational status, and such stays don’t count as inpatient readmissions. Savvy administrators therefore encourage gaming the system through liberal use of the observational stay.

“Since CMS instituted this rule in 2013, there has been a surge in utilization of observational status versus inpatient status,” Dr. Masri noted.

That might make sense if the patients selected for in-hospital observation were less ill at the time than the heart failure patients admitted as inpatients, but that wasn’t the case in his large, retrospective study.

Dr. Masri reported on 21,339 patients with a total of 52,493 admissions for a primary diagnosis of heart failure during 2008-2015 in an 18-hospital health care system. After excluding admissions which involved cardiac surgery or in-hospital mortality, the total was 50,654 admissions.

Of these admissions, 5% were for in-hospital observation; 17% were inpatient admissions with discharge in less than 2 days. The two groups were similar in terms of age, comorbid conditions, and use of guideline-directed medications, although 36% of patients admitted under observation had a left ventricular ejection fraction below 40%, compared with 30% of those with an inpatient admission for less than 2 days.

The majority of patients in both groups were readmitted for heart failure within 1 year; however, the readmission rate was 23% lower in the group with an inpatient stay of less than 2 days, in an analysis adjusted for age, sex, ejection fraction, hypertension, diabetes, pneumonia, chronic obstructive pulmonary disease, liver disease, and renal failure.

Similarly, the group with an inpatient stay of less than 2 days’ duration was 24% less likely to have a cardiac readmission within 1 year than the group admitted for a penalty-free observational stay. The short inpatient stay group’s 1-year all-cause readmission rate was also 24% lower. All of these differences were statistically significant and clinically meaningful.

Yet 1-year all-cause mortality in the two groups was no different.

“This suggests that the difference between these two groups is more of an administrative distinction than a reflection of patient status at time of admission. It looks like it’s just random,” according to Dr. Masri. “There is a real need for a patient-centered, streamlined approach in evaluating and treating patients with heart failure, with a revised treatment-based algorithm and admission rules that guide physicians and shape health care policy.”

He reported having no financial conflicts of interest regarding this study.

Mixed findings on iron repletion in HF

Article Type
Changed

 

– Oral iron supplementation was declared ineffective for the treatment of iron deficiency in patients with heart failure with reduced ejection fraction in one major randomized trial while intravenous ferric carboxymaltose improved exercise capacity and quality of life in another study presented at the American Heart Association scientific sessions.

Iron deficiency is present in roughly half of patients with heart failure with reduced ejection fraction (HFrEF). In affected patients it’s associated with diminished functional capacity and poor quality of life, and is an independent predictor of mortality. Thus, it has emerged as a potential therapeutic target in HFrEF.

Dr. Gregory D. Lewis
Many physicians with iron deficiency in HFrEF on their radar have been prescribing oral iron in affected patients on the grounds that it’s inexpensive, readily available, and perhaps could help. But its clinical utility was untested until Gregory D. Lewis, MD, presented the results of the IRONOUT HF trial at the AHA scientific sessions. And IRONOUT HF showed the therapy to be unequivocally without benefit.

The IRONOUT HF (Oral Iron Repletion Effects on Oxygen UpTake in Heart Failure) trial was a multicenter, randomized, double-blind, placebo-controlled clinical trial conducted by the National Heart, Lung, and Blood Institute’s Clinical Heart Failure Network investigators. It included 225 patients with HFrEF and iron deficiency who were randomized to 16 weeks of oral iron polysaccharide at 150 mg b.i.d. or matching placebo.

The primary endpoint was change from baseline to 16 weeks in exercise capacity, as measured via peak oxygen uptake during cardiopulmonary exercise testing. The results were no better in the iron-supplemented group than in placebo-treated controls. Nor was there any benefit for oral iron therapy in terms of quality of life, as assessed by the Kansas City Cardiomyopathy Questionnaire or any of numerous other secondary endpoints, according to Dr. Lewis, head of the heart failure section and director of the cardiopulmonary exercise testing laboratory at Massachusetts General Hospital, Boston.

Participants’ mean baseline hemoglobin level was 12.6 g/dL, but whether patients were anemic at baseline or not made no difference in terms of outcomes. Rates of venous congestion and bleeding were low during the trial.

The problem, the investigators found, was that high-dose oral iron only minimally repleted iron stores. Transferrin saturation increased by a paltry absolute 3% after 16 weeks of twice-daily therapy. Serum ferritin levels increased only 1/20th as much as after intravenous iron ferric carboxymaltose therapy in the earlier positive FAIR-HF (Ferinject Assessment in Patients With Iron Deficiency and Chronic Heart Failure) trial (N Engl J Med. 2009 Dec 17;361:2436-48).

Levels of hepcidin were elevated in study participants. And the higher the level of hepcidin – which Dr. Lewis called “a massive regulator of iron bioavailability and absorption” – the more refractory patients were to oral iron repletion.

Dr. Stefan D. Anker
Discussant Stefan D. Anker, MD, expanded on this point. Hepcidin regulates iron entry into the body via the gut. If the hepcidin level is elevated because of systemic inflammation, it will deny entry to iron by upregulating ferroportin or direct the iron to be sequestered in macrophages.

“Hepcidin was invented by nature to protect against iron from stimulating growth of bacteria. And when it’s elevated, taking iron orally just has no chance of success,” explained Dr. Anker, professor of cardiology at the University of Gottingen (Germany).

Dr. Anker, who chaired the positive FAIR-HF trial of intravenous iron, said IRONOUT HF was a very well-conducted and definitive clinical trial of oral iron supplementation in HFrEF.

“It’s very simple: Oral iron does not work in patients with chronic heart failure. That’s the take home message. It’s true for peak VO2 [oxygen consumption], for 6-minute walk distance, for symptoms, for quality of life, and even for surrogate markers like NT-proBNP [N-terminal pro b-type natriuretic peptide]. If iron doesn’t get into the body, it’s really difficult to [imagine] that the iron that doesn’t get into the body can exert an effect,” he said.

Dr. Dirk J. van Veldhuisen
At the same late-breaking clinical trials session, Dirk J. van Veldhuisen, MD, presented the results of EFFECT-HF (Effect of Ferric Carboxymaltose on Exercise Capacity in Patients With Iron Deficiency and Chronic Heart Failure), a multicenter European open-label trial in which 172 patients with HFrEF and iron deficiency were randomized to intravenous ferric carboxymaltose or standard therapy with no placebo control. Patients in the active treatment arm received on average 1,200 mg of ferric carboxymaltose dosed in two or three sessions 6 weeks apart.

The primary endpoint in EFFECT-HF was assessor-blinded change in peak VO2 from baseline to week 24. The control group experienced a decrease in peak VO2 over time such that there was a significant difference of 1.0 mL/kg per minute between the two groups.

The ferric carboxymaltose recipients also did significantly better in terms of secondary endpoints including improvement in New York Heart Association functional class, self-reported Patient Global Assessment score, and quality-of-life measures, reported Dr. van Veldhuisen, professor and chairman of cardiology at University Medical Center Groningen (the Netherlands).

Session moderator Clyde Yancy, MD, commented that intravenous iron is not ready for prime time use in clinical practice for several reasons. The open-label EFFECT-HF trial, like the earlier positive double-blind FAIR-HF and CONFIRM-HF IV ferric carboxymaltose trials, was too modest in size to be convincing, especially since this is an expensive and intrusive therapy.

“The endpoint of peak VO2, although a very powerful endpoint, is still one for which there may be some subjectivity, and so we need a more definitive endpoint to be absolutely certain about the potential benefit of the administration of ferric carboxymaltose,” said Dr. Yancy, professor of medicine and chief of cardiology at Northwestern University in Chicago.

Discussant Adrian Hernandez, MD, of the Duke Clinical Research Institute in Durham, N.C., said he considers peak VO2 an important endpoint.

“When you talk to patients, exercise capacity is an outcome that matters to them,” he said. “They often comment that what matters to them is living longer with a better quality of life, free of worsening heart failure, and having improvement in everyday functional status. So the cardiopulmonary exercise test is not just a surrogate endpoint; it’s a measure of functional outcome that matters to patients,” he said.

Still, like Dr. Yancy, Dr. Hernandez said he thinks it’s time to have larger, longer, definitive trials with clinical endpoints in order to understand the role of intravenous iron. Both cardiologists applauded Dr. Anker’s announcement that such a trial, known as FAIR-HF2, is now getting started.

The IRONOUT HF trial was funded by the National Institutes of Health. Dr. Lewis reported receiving research support from a handful of pharmaceutical and medical device companies. Dr. van Velduisen reported serving as a scientific adviser to Vifor Pharma, which sponsored the EFFECT-HF trial. Dr. Anker, who was an EFFECT-HF investigator, serves as a consultant to Vifor and several other companies. Dr. Hernandez was an IRONOUT HF investigator and reported receiving research grants from a handful of pharmaceutical companies.

Patients in the active treatment arm received on average 1,200 mg of ferric carboxymaltose dosed in two or three sessions 6 weeks apart.

The primary endpoint in EFFECT-HF was assessor-blinded change in peak VO2 from baseline to week 24. The control group experienced a decrease in peak VO2 over time such that there was a significant difference of 1.0 mL/kg per minute between the two groups.

The ferric carboxymaltose recipients also did significantly better in terms of secondary endpoints including improvement in New York Heart Association functional class, self-reported Patient Global Assessment score, and quality-of-life measures, reported Dr. van Veldhuisen, professor and chairman of cardiology at University Medical Center Groningen (the Netherlands).

Session moderator Clyde Yancy, MD, commented that intravenous iron is not ready for prime time use in clinical practice for several reasons. The open-label EFFECT-HF trial, like the earlier positive double-blind FAIR-HF and CONFIRM-HF IV ferric carboxymaltose trials, was too modest in size to be convincing, especially since this is an expensive and intrusive therapy.

“The endpoint of peak VO2, although a very powerful endpoint, is still one for which there may be some subjectivity, and so we need a more definitive endpoint to be absolutely certain about the potential benefit of the administration of ferric carboxymaltose,” said Dr. Yancy, professor of medicine and chief of cardiology at Northwestern University in Chicago.

Discussant Adrian Hernandez, MD, of the Duke Clinical Research Institute in Durham, N.C., said he considers peak VO2 an important endpoint.

“When you talk to patients, exercise capacity is an outcome that matters to them,” he said. “They often comment that what matters to them is living longer with a better quality of life, free of worsening heart failure, and having improvement in everyday functional status. So the cardiopulmonary exercise test is not just a surrogate endpoint; it’s a measure of functional outcome that matters to patients,” he said.

Still, like Dr. Yancy, Dr. Hernandez said he thinks it’s time to have larger, longer, definitive trials with clinical endpoints in order to understand the role of intravenous iron. Both cardiologists applauded Dr. Anker’s announcement that such a trial, known as FAIR-HF2, is now getting started.

The IRONOUT HF trial was funded by the National Institutes of Health. Dr. Lewis reported receiving research support from a handful of pharmaceutical and medical device companies. Dr. van Velduisen reported serving as a scientific adviser to Vifor Pharma, which sponsored the EFFECT-HF trial. Dr. Anker, who was an EFFECT-HF investigator, serves as a consultant to Vifor and several other companies. Dr. Hernandez was an IRONOUT HF investigator and reported receiving research grants from a handful of pharmaceutical companies.

Allogeneic stem cells show promise for treating nonischemic dilated cardiomyopathy

Article Type
Changed

 

– Allogeneic stem cells appear to be a safe treatment option for nonischemic dilated cardiomyopathy and show somewhat greater efficacy than autologous stem cells, according to the results of the randomized POSEIDON-DCM trial.

“Nonischemic dilated cardiomyopathy is an incurable condition with significant genetic and immunologic underpinnings,” noted lead investigator Joshua M. Hare, MD, director of the Interdisciplinary Stem Cell Institute and professor of medicine at the University of Miami.

Dr. Joshua M. Hare
“Mesenchymal stem cells are immunomodulatory and immunoprivileged cells with proregenerative effects that have been shown to be safe and to promote reverse remodeling in ischemic cardiomyopathy.”

The phase I/II trial undertook a head-to-head comparison of allogeneic and autologous bone marrow–derived mesenchymal stem cells in 37 patients with nonischemic dilated cardiomyopathy.

Results presented at the American Heart Association scientific sessions and simultaneously published (J Am Coll Cardiol. 2016. doi: 10.1016/j.jacc.2016.11.009) showed that none of the patients in either group experienced a 30-day treatment-emergent serious adverse event, the trial’s primary endpoint.

The allogeneic group had a greater shift to a lesser inflammatory immune profile, and, at 12 months, a lower rate of major adverse cardiac events and more improvement in walk test distance. Additionally, half of patients in the allogeneic group no longer met the ejection fraction cutoff typically used to define dilated cardiomyopathy, compared with only about one-fifth of those in the autologous group.

“Immunomodulation may contribute to the efficacy of allogeneic human mesenchymal stem cells in nonischemic dilated cardiomyopathy, as we have shown suppression of immune activation to a greater degree with the allo versus auto cells,” Dr. Hare said.

“We argue that these data support the use of allogeneic mesenchymal stem cell therapy in future pivotal placebo-controlled clinical trials for this patient population, an important patient population with significant unmet need.”

Trial details

The patients enrolled in POSEIDON-DCM had left ventricular dysfunction due to nonischemic dilated cardiomyopathy and were randomized evenly to allogeneic or autologous stem cell therapy. Stem cells were delivered by transendocardial injection into 10 left ventricular sites using a catheter.

Major finding: At 12 months, the allogeneic group had lower rates than the autologous group of major adverse cardiac events (20.3% vs. 57.1%, P = .0186) and all-cause rehospitalizations (28.2% vs. 70.0%, P = .0447).

Data source: A randomized phase I/II trial among 37 patients with nonischemic dilated cardiomyopathy (POSEIDON-DCM trial).

Disclosures: Dr. Hare disclosed that he has an ownership interest in and is a consultant or advisory board member for Vestion.

TRUE-AHF: Urgent vasodilator therapy in acute HF provides no long-term benefit

Article Type
Changed

– An investigational synthetic natriuretic peptide given early during hospitalization for acute decompensated heart failure didn’t produce any of the hoped-for intermediate- or long-term clinical benefits in the phase III TRUE-AHF study, Milton Packer, MD, reported at the American Heart Association scientific sessions.

The failure of this investigational vasodilator, ularitide, to influence downstream cardiovascular mortality or early readmission for heart failure closes the door on the once-promising hypothesis that myocardial microinjury occurring during ADHF is due to ventricular distension, observed Dr. Packer, the Distinguished Scholar in Cardiovascular Science at Baylor University Medical Center, Dallas. “Ularitide did exactly what we expected it to do while we were giving it: we caused intravascular decompression, we reduced cardiac wall stress, but we did not affect cardiac microinjury, and we didn’t change long-term cardiovascular mortality or any of our secondary endpoints, including and in particular the 30-day risk of rehospitalization for heart failure,” he said.

Bruce Jancin/Frontline Medical News
Dr. Milton Packer
TRUE-AHF was a double-blind, randomized trial in which 2,157 patients hospitalized for acute decompensated heart failure (ADHF) at 156 centers in 23 countries were assigned to a 48-hour intravenous infusion of ularitide or placebo. Of note, treatment began early: a median of 6.1 hours from the time of initial clinical evaluation. That’s the soonest-ever intervention investigated in a clinical trial in ADHF.

During a median follow-up of 15 months there were 236 cardiovascular deaths in the ularitide group and 225 in the control group, a nonsignificant difference. Nor were there any differences between the two groups in secondary endpoints including length of stay in the ICU during the index hospitalization, rehospitalization for ADHF within 30 days of discharge, or the composite of all-cause mortality or cardiovascular hospitalization within 6 months, which occurred in 40.7% of the ularitide group and 37.2% of controls.

The explanation for this lack of long-term benefit lies in the finding that myocardial microinjury wasn’t prevented by the rapid reduction of cardiac distension produced by ularitide. This was evident in the therapy’s inability to dampen the rise in high-sensitivity cardiac troponin T which occurred in the initial 48 hours of the study.

“The trial demonstrated the effects and safety of ularitide. However, to gain long-term benefits on hospitalizations and death in patients following a hospital admission for heart failure, physicians must focus on the drugs that patients take as an outpatient rather than the drugs they receive as an inpatient,” Dr. Packer concluded.

Dr. Clyde Yancy
Discussant Clyde Yancy, MD, called ADHF a persistent challenge.

“Readmission rates remain stubbornly at 20% within 30 days and near 50% at 6 months. Acute decompensation is an inflection point in the natural history of heart failure with subsequent 1-year mortality rates consistently approximating 25%. Clearly there is something about the hospitalization that is a herald event which speaks to much worse outcomes, compared with chronic ambulatory heart failure,” said Dr. Yancy, professor of medicine and chief of cardiology at Northwestern University in Chicago.

He agreed with Dr. Packer that in light of the TRUE-AHF results, what Dr. Yancy termed “the early injury hypothesis” isn’t worth further pursuit.

Ularitide thus joins a long list of failed therapies for ADHF. Treatments that have convincingly been shown to have no significant impact on mortality and at best only modest impact on morbidity include continuous IV infusion of loop diuretics in the DOSE trial; the arginine vasopressin antagonists, which failed to impress in EVEREST, SECRET, and TACTICS; nesiritide (Natrecor) in the ASCEND-HF trial; and levosimendan (Simdax), which proved disappointing in the SURVIVE and REVIVE II studies, according to Dr. Yancy.

The jury is still out on serelaxin, he added. The drug showed a favorable signal in the RELAX-AHF trial. The results of RELAX II are awaited with interest.

“Today we still don’t have an effective single intervention for acute decompensated heart failure other than process-of-care improvement,” the cardiologist noted.

What holds promise for improved long-term outcomes in ADHF at this point? Dr. Yancy said sacubitril/valsartan (Entresto) is intriguing based upon the results of the PARADIGM-HF trial (N Engl J Med. 2014;371:993-1004). But the drug needs to be studied prospectively in patients in the throes of ADHF before it can appropriately be recommended for the purpose of changing the natural history of this disorder, Dr. Yancy stressed.

Devices such as the implantable pulmonary catheter are under study as a promising means of altering the natural history of ADHF by identifying actionable signals of impending decompensation weeks beforehand, he added.

The TRUE-AHF trial was sponsored by Cardiorentis. Dr. Packer reported serving as a consultant to that company and more than a dozen other pharmaceutical and medical device companies.

Interatrial shunt benefits sustained for 1 year in HFpEF patients

Article Type

NEW ORLEANS – An interatrial septal shunt device continued to provide “sustained and meaningful clinical benefit” at 1-year follow-up for 64 patients who had heart failure with preserved ejection fraction (HFpEF), David M. Kaye, MD, PhD, reported at the American Heart Association scientific sessions.

American Heart Association
Dr. David Kaye
REDUCE LAP-HF (Reduced Elevated Left Atrial Pressure in Patients With Heart Failure), a manufacturer-sponsored, nonrandomized, open-label study established the device’s safety and performance in a relatively small group of patients. A larger, double-blind, randomized trial with sham controls is now underway “to validate the utility of this novel therapy,” said Dr. Kaye of Alfred Hospital, Melbourne.

Overall survival at 1 year was 95%. Three patients died (one from combined pneumonia and renal failure, one from a fatal stroke, and one from an undetermined cause) and one was lost to follow-up. Thirteen patients required 17 hospitalizations for heart failure.

Six-minute walk distance improved from 331 meters at baseline to 363 meters. NYHA classification improved dramatically, as did quality of life scores as assessed by the Minnesota Living with HF questionnaire.

All 48 devices that were evaluable on echocardiographic imaging remained patent, showing continued left-to-right shunting. Left ventricular ejection fraction remained unchanged while right ventricular ejection fraction was significantly elevated over baseline levels. “In conjunction, there were modest but stable reductions in LV end-diastolic volume index with a concomitant rise in RV end-diastolic index,” he said.

A subset of 18 study participants underwent heart catheterization during both rest and exercise so that hemodynamics could be assessed. Exercise time increased significantly, from 8.2 minutes at baseline to 9.7 minutes at 6 months and to 10.4 minutes at 1 year. Similarly, peak work capacity during supine cycling increased from 48 watts at baseline to 60 watts at 6 months and 55 watts at 1 year. These benefits occurred without any increase in pulmonary capillary wedge pressure.

Systemic blood pressure did not change over time, either at rest or during exercise. Left and right atrial volumes also remained unchanged.

Perhaps most importantly, Dr. Kaye said, right-sided cardiac output increased significantly, while left-sided cardiac output remained unchanged. There was no evidence of increased pulmonary pressure or pulmonary vascular resistance. This meant that patients could do more physical activity for a given level of left atrial pressure, he said.

American Heart Association
Dr. Nancy Sweitzer
To discussant Nancy K. Sweitzer, MD, PhD, the most important aspect of the 1-year results of REDUCE LAP-HF was the strong showing for device safety. Sustained, chronic elevation in right-sided output has never been studied, so the effects are unknown. But the results are encouraging because device flow remained left-to-right in all evaluated patients.

Furthermore, 1-year mortality was lower in this trial, at 4.6%, than in the placebo groups of the I-PRESERVE trial in irbesartan (5.2%) and the U.S. group of the TOPCAT trial in spironolactone (7.7%), said Dr. Kaye, professor and chief of cardiology at the University of Arizona, Tuscon.

Device therapy could have an enormous impact in carefully selected patients with HFpEF, for whom there are no medical treatments, despite the nonrandomized nature of the trial.

REDUCE LAP-HF was funded by Corvia Medical, maker of the shunt device. Dr. Kaye is an unpaid member of Corvia’s scientific advisory group. Dr. Sweitzer is an investigator in the ongoing randomized trial of the interatrial shunt.

REDUCE LAP-HF (Reduced Elevated Left Atrial Pressure in Patients With Heart Failure), a manufacturer-sponsored, nonrandomized, open-label study established the device’s safety and performance in a relatively small group of patients. A larger, double-blind, randomized trial with sham controls is now underway “to validate the utility of this novel therapy,” said Dr. Kaye of Alfred Hospital, Melbourne.

Overall survival at 1 year was 95%. Three patients died (one from combined pneumonia and renal failure, one from a fatal stroke, and one from an undetermined cause) and one was lost to follow-up. Thirteen patients required 17 hospitalizations for heart failure.

Six-minute walk distance improved from 331 meters at baseline to 363 meters. NYHA classification improved dramatically, as did quality of life scores as assessed by the Minnesota Living with HF questionnaire.

All 48 devices that were evaluable on echocardiographic imaging remained patent, showing continued left-to-right shunting. Left ventricular ejection fraction remained unchanged while right ventricular ejection fraction was significantly elevated over baseline levels. “In conjunction, there were modest but stable reductions in LV end-diastolic volume index with a concomitant rise in RV end-diastolic index,” he said.

A subset of 18 study participants underwent heart catheterization during both rest and exercise so that hemodynamics could be assessed. Exercise time increased significantly, from 8.2 minutes at baseline to 9.7 minutes at 6 months and to 10.4 minutes at 1 year. Similarly, peak work capacity during supine cycling increased from 48 watts at baseline to 60 watts at 6 months and 55 watts at 1 year. These benefits occurred without any increase in pulmonary capillary wedge pressure.

Systemic blood pressure did not change over time, either at rest or during exercise. Left and right atrial volumes also remained unchanged.

Perhaps most importantly, Dr. Kaye said, right-sided cardiac output increased significantly, while left-sided cardiac output remained unchanged. There was no evidence of increased pulmonary pressure or pulmonary vascular resistance. This meant that patients could do more physical activity for a given level of left atrial pressure, he said.

To discussant Nancy K. Sweitzer, MD, PhD, the most important aspect of the 1-year results of REDUCE LAP-HF was the strong showing for device safety. Sustained, chronic elevation in right-sided output has never been studied, so the effects are unknown. But the results are encouraging because device flow remained left-to-right in all evaluated patients.

Furthermore, 1-year mortality was lower in this trial, at 4.6%, than in the placebo groups of the I-PRESERVE trial in irbesartan (5.2%) and the U.S. group of the TOPCAT trial in spironolactone (7.7%), said Dr. Kaye, professor and chief of cardiology at the University of Arizona, Tuscon.

Device therapy could have an enormous impact in carefully selected patients with HFpEF, for whom there are no medical treatments, despite the nonrandomized nature of the trial.

VIDEO: Bariatric surgery may protect against heart failure

– Results of a new 40,000-patient Swedish observational study provide the strongest evidence to date suggesting a causal relationship between bariatric surgery and reduced risk of heart failure, according to Johan Sundström, MD.

The study, which included patients drawn from two large Swedish national registries, demonstrated that bariatric surgery was associated with a 46% reduction in the incidence of heart failure during a median 4.1 years of follow-up, compared with an intensive lifestyle modification program for weight loss.

“These are observational data, but it’s a very large study population – and probably there will never be a large randomized trial of bariatric surgery versus weight loss through intensive lifestyle modification as a means of reducing the risk of heart failure,” Dr. Sundström, professor of epidemiology and a cardiologist at Uppsala (Sweden) University, said at the American Heart Association scientific sessions.

The study included 25,804 bariatric surgery patients in SOReg, the Scandinavian Obesity Surgery Registry, and a matched comparator group of 13,701 participants in a Swedish national registry of obese participants in a commercial Sweden-based intensive structural lifestyle modification program for weight loss called Itrim. The two groups were matched for baseline body mass index, which was a mean of 41.5 kg, and numerous other demographic factors and comorbid conditions. Participants weighed an average of 119 kg at baseline. None of the subjects had a history of heart failure.

The bariatric surgery group lost substantially more weight than did the lifestyle modification group: an average loss of about 35 kg after 1 year, which was 18.8 kg more than in the lifestyle modification group. After 2 years, the bariatric surgery group had an average of 22.6 kg more weight loss than did the comparison group.

The primary outcome was hospitalization for new-onset heart failure during a median 4.1 years of follow-up. Subjects were well below the age range when the incidence of heart failure accelerates – they averaged 41 years of age – but 73 of them did develop heart failure during follow-up. The incidence was 46% lower in the bariatric surgery patients. This supports the study hypothesis that bariatric surgery leads to a low incidence of new-onset heart failure, compared with intensive lifestyle modification because of its larger weight loss effect.

When Dr. Sundström and his coinvestigators combined the two study groups, they found that a 10-kg weight loss at 1 year was associated with a 23% reduction in the risk of heart failure during follow-up, irrespective of whether the weight loss was achieved surgically or through the lifestyle program.

“A great way of studying causality is to take away the exposure and note what happens to the outcome. If there’s a causal link, then if you take away the risk factor – in this case, obesity – the disease should go away,” he explained in a video interview.

The reduced risk of heart failure in the bariatric surgery patients wasn’t because of fewer acute MIs. Indeed, their acute MI rate during follow-up was similar to that of the lifestyle modification group. But bariatric surgery was associated with relative risk reductions of 35%-37% for atrial fibrillation or need for diabetes or blood pressure–lowering medications at 1 year – and atrial fibrillation, diabetes, and hypertension are all established risk factors for heart failure, Dr. Sundström noted.

The Itrim intensive lifestyle modification program entailed an initial very-low-energy diet for the first 3 months in order to achieve massive weight loss, followed by a 9-month maintenance program involving motivational counseling, exercise, behavioral therapy, and a restricted diet.

Dr. Sundström said he and his coinvestigators plan to continue the study and expand it to look at differences in additional cardiovascular endpoints as patients age.

The study was funded by the U.S. National Institute of Diabetes and Digestive and Kidney Diseases, Uppsala University, the Karolinska Institute, and the Swedish Research Council. Dr. Sundström reported serving as a scientific advisor to Itrim.

Heart failure readmission metric not linked to care quality

Metric flaws should raise alarm
Article Type
Changed

Metrics used by the Centers for Medicare & Medicaid Services to determine penalties for heart failure hospital readmissions are not associated with quality of care or overall clinical outcomes, according to data presented at the annual scientific sessions of the American Heart Association.

Ambarish Pandey, MD, of the University of Texas Southwestern Medical Center in Dallas, and his colleagues analyzed data from centers participating in the American Heart Association’s Get With The Guidelines-Heart Failure (GWTG-HF) registry linked to Medicare claims from July 2008 to June 2011. Centers were stratified as having low risk-adjusted readmission rates and high risk-adjusted readmission rates based on publicly available data from 2013.

The study included 171 centers with 43,143 patients. Centers were almost evenly split between low- and high-risk–adjusted 30-day readmission rates, with just a few more (51%) falling in the low-risk–adjusted category.

Performance was nearly equal (95.7% for centers with a low risk-adjusted readmission rate vs. 96.5% for those with high risk-adjusted rate) for median adherence to all performance measures, as was the case for median percentage of defect-free care (90.0% vs. 91.1%, respectively) and composite 1-year outcome of death or all-cause readmission rates (median 62.9% vs. 65.3%, respectively). The higher readmission group had higher 1-year all-cause readmission rates (median, 59.1% vs. 54.7%), Dr. Pandey and his colleagues reported in the study that was published simultaneously in JACC: Heart Failure (2016 Nov 15. doi. org/10.1016/j.jchf.2016). One-year mortality rates were lower in the higher readmission group with a trend toward statistical significance (median, 28.2% vs. 31.7%; P = 0.07).

Taken together, the findings suggest the 30-day readmission metrics currently used by CMS to determine readmission penalties are not associated with quality of care or overall clinical outcomes, Dr. Pandey and his colleagues wrote. Results showing higher 30-day readmissions do not necessarily reflect poor quality of care and may be related to other factors.

“These findings question the usefulness of the [hospital readmission reduction program] metric in identifying and penalizing hospitals with low quality of care,” Dr. Pandey wrote, adding that the findings were consistent with previous studies that have demonstrated a lack of association between in-hospital quality of care and 30-day readmission rates.

CMS implemented the federal Hospital Readmissions Reduction Program (HRRP) in 2012 to provide financial incentives for hospitals to reduce readmissions. Under the program, CMS uses claims data to determine whether readmission rates for heart failure, acute myocardial infarction, and pneumonia at eligible hospitals are higher than would be predicted by CMS models. Centers with higher than expected readmission rates face up to a 3% reimbursement penalty.

These authors add to a chorus of voices expressing concern regarding the appropriateness and validity of the 30-day readmission metric. Arguably, this metric has driven our entire provider workforce to construct machinery designed to reduce short-term posthospitalization utilization, while doing little to improve quality for the 5.7 million (and counting) Americans with heart failure.

Dr. Marvin A. Konstam
The 30-day readmission metric, with its many flaws and clear direction to reduce utilization and cost but without focus on patient well-being, should serve as an alarm that we are heading in the wrong direction of allowing government policy makers, rather than patients, to drive the design of clinical care metrics. Alternatively, the government can and should play an important role in facilitating an environment of integrated health care systems and market-based competition, within which consumers can drive the advancement of their own health.
