Patiromer allows more CKD patients to continue on spironolactone
PHILADELPHIA – Among patients with chronic kidney disease with resistant hypertension, coadministration of patiromer enables more patients to stay on spironolactone, Bryan Williams, MD, of University College London, said at the scientific meeting of the Heart Failure Society of America.
Having the potassium-binding polymer on board allowed for more persistent use of spironolactone, both in the subgroup of patients with heart failure, and those without, he said in a late-breaking clinical trials session.
In the international, phase 2 AMBER (Spironolactone With Patiromer in the Treatment of Resistant Hypertension in Chronic Kidney Disease) trial, 295 patients with chronic kidney disease (estimated glomerular filtration rate from 25 to 45 mL/min per 1.73 m2) were randomly assigned to treatment with spironolactone either placebo (148) or patiromer (147).
, for a significant between-group difference of 19.5% (P less than .0001). In addition, blood pressure lowering was significantly greater in the patiromer (–11.7 mm Hg) than in the placebo (–10.8 mm Hg) group. Results of the AMBER trial were published concurrently with Dr. Williams’ presentation (Lancet 2019 Sep 15; doi: 10.1016/S0140-6736(19)32135-X).
While spironolactone is a “highly effective” drug, studies supporting guideline recommendations for its use in resistant hypertension have largely excluded patients with advanced chronic kidney disease because of increased risk of developing spironolactone-induced hyperkalemia, Dr. Williams told attendees. It remains unclear, however, whether coadministration of patiromer will improve long-term outcomes. Also, many placebo-treated patients in AMBER were able to continue on spironolactone without the help of patiromer, prompting one attendee to question whether there was a smarter way to target the drug, rather than treating all patients up front.
“I don’t think it’s going to be easy to say, ‘this patient’s going to respond, and this patient’s not going to respond,’ ” Dr. Williams said in response, “but at least we have an opportunity to try now in a group of patients who simply may be denied treatment because of a perception that it is difficult to use spironolactone in them.”
That perception is actually not unreasonable, he added, given that 66% of patients in the placebo group in AMBER developed hyperkalemia, suggesting that spironolactone is “not an easy drug to use” in chronic kidney disease patients.
John Teerlink, MD, of the San Francisco VA Medical Center, said the AMBER study is “another building block” in a series of developments of enabling therapies.
“I think it’s a great message for all of us to begin thinking about other therapies we can use to help modify our use of these potential life-saving therapies,” he said in a panel discussion of the results.
Patiromer’s impact on longer-term outcomes is the focus of DIAMOND, a phase 3, randomized, placebo controlled trial that is currently recruiting. DIAMOND will determine whether giving patiromer to patients who developed hyperkalemia on renin-angiotensin-aldosterone system (RAAS) inhibitors decreases cardiovascular deaths and hospitalizations, by virtue of enabling continued RAAS inhibitor use.
Funding for AMBER came from Relypsa, which markets patiromer (Veltassa). Dr. Williams reported consulting for Relypsa during the conduct of the study, along with disclosures outside the scope of the AMBER study (Daiichi Sankyo, Pfizer, Novartis, Servier, Boehringer Ingelheim, and Vascular Dynamics).

REPORTING FROM HFSA 2019
Dapagliflozin approved for reducing HF hospitalization in diabetes
The Food And Drug Administration has approved the sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin (Farxiga) for reducing the risk of hospitalization for heart failure in adults with type 2 diabetes and established cardiovascular disease or multiple cardiovascular risk factors, according to a statement from AstraZeneca.
The approval was based on results from the DECLARE-TIMI 58 cardiovascular outcomes trial, which evaluated dapagliflozin in more than 17,000 patients with type 2 diabetes and cardiovascular risk factors or cardiovascular disease. They showed that dapagliflozin significantly reduced the risk of the primary composite endpoint of hospitalization for heart failure by 27%, compared with placebo (2.5% vs. 3.3%; HR, 0.73; 95% confidence interval, 0.61-0.88).
The drug is an oral, once-daily SGLT2 inhibitor initially approved as a monotherapy or combination therapy for glycemic control in adults with type 2 diabetes. It has additional benefits of weight loss and reduction in blood pressure in concert with diet and exercise in the same population.
“,” Ruud Dobber, PhD, executive vice president of the company’s biopharmaceuticals business unit, said in the statement. “This is promising news for the 30 million people living with type 2 diabetes in the U.S., as heart failure is one of the earliest cardiovascular complications for them, before heart attack or stroke. [Dapagliflozin] now offers the opportunity for physicians to act sooner and reduce the risk of hospitalization for heart failure.”
In September, the agency granted dapagliflozin a Fast Track designation to reduce the risk of cardiovascular death, or the worsening of heart failure in adults with heart failure with reduced ejection fraction or preserved ejection fraction, based on the phase 3 DAPA-HF and DELIVER trials. It also gave the drug Fast Track designation to delay the progression of renal failure and prevent CV and renal death in patients with chronic kidney disease based on the phase 3 DAPA-CKD trial, the statement noted.

GALACTIC: Early vasodilation strategy no help in acute heart failure
PARIS – A practical strategy of early and aggressive vasodilation and optimization of long-term medication for acute heart failure did not budge all-cause mortality or 180-day readmission rates, according to results of a pragmatic trial presented at the annual congress of the European Society of Cardiology.
“To our great disappointment, the curves were superimposable” between intervention and control arms in the GALACTIC (Goal-directed Afterload Reduction in Acute Congestive Cardiac Decompensation) trial, said lead investigator Christian Eugen Mueller, MD. “There was no signal of a benefit” for those receiving the targeted intervention: the adjusted hazard ratio was 1.07 for the composite primary endpoint of all-cause mortality or 6-month readmission for acute heart failure (P = 0.59).
GALACTIC, explained Dr. Mueller, was the largest investigator-initiated, randomized, controlled trial of pharmacologic therapy for acute heart failure (AHF).
“It is different in that it did not investigate a single drug, but a strategy of early, intensive, and sustained vasodilation. It is also unique in that it used individual doses of well-characterized, widely available, and mostly inexpensive drugs,” said Dr. Mueller, director of the Cardiovascular Research Institute at the University Hospital, Basel, Switzerland. “So this would have the beauty that, if it has a positive finding, you – in whatever country you come from – would be immediately able to apply it once you’re back home in your institution.”
The study attempted to address the gap between symptom amelioration and long-term outcomes when patients arrive in the ED with AHF. “Despite symptomatic improvement achieved from loop diuretics, mortality and morbidity remain unacceptably high,” said Dr. Mueller, with 40%-50% of AHF patients experiencing rehospitalization or death within 180 days of discharge.
Much remains unknown about the optimal treatment strategy for AHF. Aggressive vasodilation has been shown to improve outcomes in less-severe AHF, and intravenous nitrates are known to improve outcomes in AHF where severe pulmonary edema is present – “a phenotype representing only about 5% of patients,” noted Dr. Mueller. Still, “it is unknown whether aggressive vasodilation also improves outcomes in the much more common less-severe phenotype.”
Also, previous trials that ran intravenous vasodilators at a fixed dose for 48 hours did not improve AHF outcomes, so a one-size-fits-all strategy was not one the GALACTIC investigators sought to pursue.
In addition to a flexible regimen, “any strategy applied needs to take into consideration that the vast majority of patients with acute heart failure, after initial treatment in the ED, are then treated in a general cardiology ward,” added Dr. Mueller.
This meant that intravenous nitrate infusion was not part of the GALACTIC trial; rather, sublingual and transdermal nitrates were used, explained Dr. Mueller. “Transdermal application has the beauty that if you have an adverse effect – and hypotension is the most dangerous one – you can immediately remove the patch, and thereby avoid any further harm.”
The two-part strategy tested in GALACTIC involved reducing cardiac filling pressures by maintaining or increasing organ perfusion, while also increasing “long-term lifesaving therapy” targeting the renin-angiotensin-aldosterone system during hospitalization, with a goal to continue optimal treatment long term.
ACE inhibitors or angiotensin receptor blockers were added on the second day of hospitalization for the intervention group, said Dr. Mueller, and “in the ideal setting, up-titrated very aggressively from day to day.
“However, as you know, up-titration to target dose is sometimes wishful thinking in this frail population,” he said, so the GALACTIC trial protocol included a scheme to back dosing off for hypotension, hypokalemia, or worsening renal function. Systolic BP guided how aggressively vasodilation and ACE inhibitor/angiotensin receptor blocker therapy were escalated.
In the end, 382 patients randomized to the intervention arm received early, intensive, and sustained vasodilation, and the 399 patients in the control arm received standard-of-care treatment according to ESC guidelines. These figures omit two patients in the standard-of-care arm who withdrew consent, but follow-up was otherwise complete, said Dr. Mueller. Physicians treating patients in both study arms had discretion to use such other therapies as loop diuretics, beta-blockers, aldosterone antagonists, and cardiac devices.
Adult patients coming to the ED with acute dyspnea classified as New York Heart Association class III or IV were eligible if they had brain natriuretic peptide (BNP) levels of at least 500 ng/L, or N-terminal of the prohormone BNP (NT-proBNP) levels of at least 2,000 ng/L.
Overall, patients enrolled in GALACTIC were in their late 70s, and women made up 37% of the population.
The actual median BNP for enrollees was about 1,250 ng/L, and the median NT-proBNP was just under 6,000 ng/L. The median left ventricular ejection fraction was 37%. About a third of patients had diabetes, and 85% had hypertension. Over half had known chronic heart failure, about a third had prior history of MI, and half of patients had atrial fibrillation at baseline.
“Signs of congestion were present in all patients, and over 90% had rales on physical examination,” said Dr. Mueller.
Patients who were destined for the ICU, those who had systolic BP below 100 mm Hg or marked creatinine elevation, or who required cardiopulmonary resuscitation were excluded. Also excluded were patients with known structural defects such as severe valvular stenosis, congenital heart disease, or hypertrophic obstructive cardiomyopathy. GALACTIC also excluded patients with isolated right ventricular failure caused by pulmonary hypertension.
Prespecified subgroup analyses compared women with men, and those younger than 75 years with older participants. Women saw a significantly higher hazard ratio for readmission or death, indicating a potential harm from the intervention, said Dr. Mueller. An additional analysis stratified patients by left ventricular ejection fraction. Aside from the intervention’s negative effect on women participating in the trial, no other subgroups benefited or were harmed by an early vasodilation strategy.
Alexandre Mebazaa, MD, the designated discussant for the presentation, said that, although the GALACTIC trial was neutral, it represents “an important step forward in acute heart failure.
“Congratulations: First, because we know that in the critically ill condition it’s very difficult to do trials,” and the GALACTIC investigators succeeded in enrolling patients within the first 5 hours of presentation to EDs, noted Dr. Mebazaa, professor of anesthesiology and critical care medicine at the Paris Diderot School of Medicine.
He added that GALACTIC succeeded in continuing vasodilator use beyond the 48-hour mark. “For the first time, you had the courage to go a little bit further down, and we see that patients got the drug with vasodilator properties for 2 days or more.”
However, the long recruitment period for GALACTIC – first enrollment began in 2007 – meant that the study design reflected a thought process about AHF that doesn’t necessarily reflect current practice, noted Dr. Mebazaa. “The trial was designed many years ago, and at that time, we were still thinking that giving very aggressive treatment in the first hours could have an impact.
“Now, when we will be treating patients with vasodilators with acute heart failure – at least myself and my group – I would really wonder whether there is still evidence in the world to support the use of those agents.”
Dr. Mueller noted limitations of the GALACTIC trial, including the lack of generalizability to patients with systolic hypotension or severe renal dysfunction, since these populations were excluded. Also, “the open-label design, which was mandated by the aim to test a strategy, not a single drug, may have introduced a bias in the unblinded assessment of dyspnea” during inpatient stay.
The study was funded by several Swiss research institutions and had no industry support. Dr. Mueller reported no relevant conflicts of interest. Dr. Mebazaa reported financial relationships with Roche, Service, Novartis, AstraZeneca, S-Form Pharma, 4Teen$4, Adrenomed, and Sphingotec.

Also, previous trials that ran intravenous vasodilators at a fixed dose for 48 hours did not improve AHF outcomes, so a one-size-fits-all strategy was not one the GALACTIC investigators sought to pursue.
In addition to a flexible regimen, “any strategy applied needs to take into consideration that the vast majority of patients with acute heart failure, after initial treatment in the ED, are then treated in a general cardiology ward,” added Dr. Mueller.
This meant that intravenous nitrate infusion was not part of the GALACTIC trial; rather, sublingual and transdermal nitrates were used, explained Dr. Mueller. “Transdermal application has the beauty that if you have an adverse effect – and hypotension is the most dangerous one – you can immediately remove the patch, and thereby avoid any further harm.”
The two-part strategy tested in GALACTIC involved reducing cardiac filling pressures by maintaining or increasing organ perfusion, while also increasing “long-term lifesaving therapy” targeting the renin-angiotensin-aldosterone system during hospitalization, with a goal to continue optimal treatment long term.
ACE inhibitors or angiotensin receptor blockers were added on the second day of hospitalization for the intervention group, said Dr. Mueller, and “in the ideal setting, up-titrated very aggressively from day to day.
“However, as you know, up-titration to target dose is sometimes wishful thinking in this frail population,” he said, so the GALACTIC trial protocol included a scheme to back dosing off for hypotension, hypokalemia, or worsening renal function. Systolic BP guided how aggressively vasodilation and ACE inhibitor/angiotensin receptor blocker therapy were escalated.
In the end, 382 patients randomized to the intervention arm received early, intensive, and sustained vasodilation, and the 399 patients in the control arm received standard-of-care treatment according to ESC guidelines. These figures omit two patients in the standard-of-care arm who withdrew consent, but follow-up was otherwise complete, said Dr. Mueller. Physicians treating patients in both study arms had discretion to use such other therapies as loop diuretics, beta-blockers, aldosterone antagonists, and cardiac devices.
Adult patients coming to the ED with acute dyspnea classified as New York Heart Association class III or IV were eligible if they had brain natriuretic peptide (BNP) levels of at least 500 ng/L, or N-terminal of the prohormone BNP (NT-proBNP) levels of at least 2,000 ng/L.
Overall, patients enrolled in GALACTIC were in their late 70s, and women made up 37% of the population.
The actual median BNP for enrollees was about 1,250 ng/L, and the median NT-proBNP was just under 6,000 ng/L. The median left ventricular ejection fraction was 37%. About a third of patients had diabetes, and 85% had hypertension. Over half had known chronic heart failure, about a third had prior history of MI, and half of patients had atrial fibrillation at baseline.
“Signs of congestion were present in all patients, and over 90% had rales on physical examination,” said Dr. Mueller.
Patients who were destined for the ICU, those who had systolic BP below 100 mm Hg or marked creatinine elevation, or who required cardiopulmonary resuscitation were excluded. Also excluded were patients with known structural defects such as severe valvular stenosis, congenital heart disease, or hypertrophic obstructive cardiomyopathy. GALACTIC also excluded patients with isolated right ventricular failure caused by pulmonary hypertension.
Prespecified subgroup analyses compared women with men, and those younger than 75 years with older participants. Women saw a significantly higher hazard ratio for readmission or death, indicating a potential harm from the intervention, said Dr. Mueller. An additional analysis stratified patients by left ventricular ejection fraction. Aside from the intervention’s negative effect on women participating in the trial, no other subgroups benefited or were harmed by an early vasodilation strategy.
Alexandre Mebazaa, MD, the designated discussant for the presentation, said that, although the GALACTIC trial was neutral, it represents “an important step forward in acute heart failure.
“Congratulations: First, because we know that in the critically ill condition it’s very difficult to do trials,” and the GALACTIC investigators succeeded in enrolling patients within the first 5 hours of presentation to EDs, noted Dr. Mebazaa, professor of anesthesiology and critical care medicine at the Paris Diderot School of Medicine.
He added that GALACTIC succeeded in continuing vasodilator use beyond the 48-hour mark. “For the first time, you had the courage to go a little bit further down, and we see that patients got the drug with vasodilator properties for 2 days or more.”
However, the long recruitment period for GALACTIC – first enrollment began in 2007 – meant that the study design reflected a thought process about AHF that doesn’t necessarily reflect current practice, noted Dr. Mebazaa. “The trial was designed many years ago, and at that time, we were still thinking that giving very aggressive treatment in the first hours could have an impact.
“Now, when we will be treating patients with vasodilators with acute heart failure – at least myself and my group – I would really wonder whether there is still evidence in the world to support the use of those agents.”
Dr. Mueller noted limitations of the GALACTIC trial, including the lack of generalizability to patients with systolic hypotension or severe renal dysfunction, since these populations were excluded. Also, “the open-label design, which was mandated by the aim to test a strategy, not a single drug, may have introduced a bias in the unblinded assessment of dyspnea” during inpatient stay.
The study was funded by several Swiss research institutions and had no industry support. Dr. Mueller reported no relevant conflicts of interest. Dr. Mebazaa reported financial relationships with Roche, Service, Novartis, AstraZeneca, S-Form Pharma, 4Teen$4, Adrenomed, and Sphingotec.

TAVR, SAVR share same infective endocarditis risk
PARIS – The risk of infective endocarditis following transcatheter aortic valve replacement (TAVR) for the treatment of severe aortic stenosis proved to be the same as after surgical replacement in a French national propensity score–matched study.
This finding from what is believed to be the largest-ever study of infective endocarditis following TAVR will come as a surprise to many physicians. It’s easy to mistakenly assume the risk of this feared complication is lower – and perhaps even negligible – in TAVR patients since the procedure doesn’t involve a significant surgical wound, it’s briefer, the hospital length of stay is shorter, and recovery time is markedly less than with surgical aortic valve replacement (SAVR).
Not so, Laurent Fauchier, MD, PhD, said in presenting the study findings at the annual congress of the European Society of Cardiology.
“Do not think there is a lower risk of infective endocarditis. Be aware, be careful, and provide appropriate antibiotic prophylaxis, just as surgeons do in SAVR. Don’t think, as I did, that with TAVR with no pacemaker implantation there is no risk of infective endocarditis. The TAVR valve is a device, it’s a prosthesis, and the risk is very similar to that of surgery,” advised Dr. Fauchier, a cardiologist at Francois Rabelais University in Tours, France.
He presented a study of all of the nearly 108,000 patients who underwent isolated TAVR or SAVR in France during 2010-2018. The data source was the French national administrative hospital discharge record system. Since the TAVR patients were overall markedly older and sicker than the SAVR patients, especially during the first years of the study, he and his coinvestigators performed propensity score matching using 30 variables, which enabled them to narrow the field of inquiry down to a carefully selected study population of 16,291 TAVR patients and an equal number of closely similar SAVR patients.
A total of 1,070 cases of infective endocarditis occurred during a mean follow-up of just over 2 years. The rate of hospital admission for this complication was 1.89% per year in the TAVR group and similar at 1.71% per year in the SAVR cohort.
Of note, all-cause mortality in TAVR patients who developed infective endocarditis was 1.32-fold greater than it was in SAVR patients with infective endocarditis, a statistically significant difference. The explanation for the increased mortality risk in the TAVR group probably has to do at least in part with an inability on the part of the investigators to fully capture and control for the TAVR group’s greater frailty, according to the cardiologist.
Risk factors for infective endocarditis shared in common by TAVR and SAVR patients included male gender, a higher Charlson Comorbidity Index score, and a greater frailty index. The main predictors unique to the TAVR patients were atrial fibrillation, anemia, and tricuspid regurgitation. And although pacemaker and defibrillator implantation were risk factors for infective endocarditis in the SAVR patients, it wasn’t predictive of increased risk in the TAVR population. Dr. Fauchier called this finding “quite reassuring” given that roughly 20% of the TAVR group received a pacemaker.
The causative microorganisms for infective endocarditis were essentially the same in the TAVR and SAVR groups, simplifying antimicrobial prophylaxis decision making.
Dr. Fauchier reported having no financial conflicts regarding the study, conducted free of commercial support. He serves as a consultant to and/or on speakers’ bureaus for Bayer, BMS Pfizer, Boehringer Ingelheim, Medtronic, and Novartis.

Treatment guided by remote readings works when used as intended
PHILADELPHIA – A heart failure management strategy guided by home lung fluid measurements from the remote dielectric sensing (ReDS) system can significantly reduce recurrent hospitalizations, as long as the technology is used as intended.
A ReDS-directed management strategy did not significantly reduce recurrent hospitalizations for acute decompensated heart failure (ADHF) in the traditional intent-to-treat analysis of the randomized, controlled SMILE trial, William T. Abraham, MD, of the Ohio State University, Columbus, said at the annual scientific meeting of the Heart Failure Society of America.
However, use of the Food and Drug Administration–cleared thoracic fluid status monitoring system to guide treatment changes did cut such hospitalizations by 58% in a modified intent-to-treat population that excluded patients who failed to take daily measurements at home and who didn’t receive modified treatment despite actionable readings, Dr. Abraham reported in an oral presentation.
“These observations may support an adherence-based approach to the utilization and reimbursement of ReDS-guided management in recently discharged ADHF patients,” he said.
The ReDS system consists of a device that, within about 90 seconds, provides a measurement of lung fluid via a focused electromagnetic radar beam that passes through the right lung, Dr. Abraham said. Clinicians access data from measurements patients initiate at home through a secure, cloud-based system, and then initiate changes to heart failure management as warranted based on a ReDS-specific treatment algorithm, Dr. Abraham said.
The postmarketing SMILE study of the ReDS system was stopped early because of an administrative decision by the sponsor, according to Dr. Abraham. However, 268 patients enrolled at 43 U.S. sites continued to the end of the study, with an average follow-up of about 6 months, while readmissions were collected and adjudicated by an independent clinical events committee.
A total of 135 patients were randomized to a ReDS-based management strategy, while 133 were randomized to standard of care, the investigator said.
Most of the medication changes made in response to ReDS measurements were increased diuretics because of high lung fluid volume measurements, or decreased diuretics in response to low measurements, though some changes in vasodilator medications were also made, Dr. Abraham said.
The ReDS-directed management approach yielded a “highly nonsignificant” 19% reduction in recurrent or cumulative heart failure readmissions (P = .36); by contrast, after removing nonadherent, noncompliant cases, there were 11 hospitalizations in 91 treatment patients, compared with 43 hospitalizations in 133 control patients, yielding a hazard ratio of 0.42 (95% CI, 0.22-0.82; P = .01).
“This comes back to the adage that, if you don’t use it, you can’t improve clinical outcomes,” he said, explaining that this study’s modified intent-to-treat population was defined by excluding patients who took no ReDS measurements for more than 20 consecutive days; or by clinicians who received at least eight notifications of out-of-range ReDS values yet didn’t implement the ReDS treatment algorithm.
There were no adverse events reported as being definitely related to the use of the device, and five adverse events reported as possibly related to the device, Dr. Abraham said.
SMILE was sponsored by Sensible Medical Innovations. Dr. Abraham reported disclosures (consultant/advisory board) related to Sensible Medical Innovations, Abbott, Boehringer Ingelheim, Victorious Medical, V-Wave Medical, and others.

FDA adds diabetic kidney disease, heart failure indications to canagliflozin
The Food and Drug Administration has approved canagliflozin (Invokana) for the treatment of diabetic kidney disease and for reduction of the risk of hospitalization for heart failure in patients with type 2 diabetes and diabetic kidney disease, which makes it the first drug indicated for diabetic kidney disease treatment in 20 years.
FDA approval, which was announced in a press release by Janssen, the drug’s manufacturer, is based on results from the phase 3 CREDENCE trial. In that study patients with type 2 diabetes and chronic diabetic kidney disease received either 100 mg canagliflozin or placebo. Patients who received canagliflozin experienced a 30% reduction in the risk of the primary composite endpoint, which included end-stage kidney disease, doubling of serum creatinine, and renal or cardiovascular death. The risk of secondary outcomes were also reduced in patients receiving canagliflozin, including a 39% reduction in the risk of hospitalization for heart failure.
The most common adverse events associated with canagliflozin, according to the label, are female genital mycotic infections, urinary tract infection, and increased urination. Serious adverse events associated with canagliflozin include ketoacidosis, kidney problems, serious urinary tract infections, hypoglycemia, necrotizing fasciitis, serious allergic reaction, and bone fractures.
“The real battle to turn the tide on kidney disease is in early detection and slowing its progression so that patients stay healthier and fewer patients reach kidney failure,” LaVerne A. Burton, president and CEO of the American Kidney Fund, said in the press release. “We are so grateful that advances in kidney disease research are producing treatment options that help to slow the progression of diabetic kidney disease and reduce the risk of hospitalization for heart failure.”

Heart disease raises risk of severe cutaneous adverse reactions to allopurinol
Researchers have found that patients with heart disease have an increased risk of hospitalization for severe cutaneous adverse reactions to allopurinol, with factors like chronic kidney disease and high initial dosage adding to that risk.
“Physicians who prescribe allopurinol should look for these risk factors so that they may consider initiating lower-dosage allopurinol and other precautions, which may prevent this rare but serious adverse reaction,” Chio Yokose, MD, of Massachusetts General Hospital in Boston and coauthors wrote in the Canadian Medical Association Journal.
To further investigate known associations between heart disease and severe cutaneous adverse reactions to allopurinol – including Stevens-Johnson syndrome and toxic epidermal necrolysis – the researchers used an administrative database known as Population Data BC to conduct a cohort study of allopurinol initiators in British Columbia between 1997 and 2015. Individuals with a history of severe cutaneous adverse reactions before starting allopurinol were excluded.
Of the 130,325 allopurinol users identified, 109 were hospitalized for allopurinol-associated severe cutaneous adverse reactions within 3 months of starting the drug. One in 655 allopurinol users with heart disease were admitted to the hospital for allopurinol-associated severe cutaneous adverse reaction (risk ratio = 1.53 per 1,000; 95% confidence interval, 1.10-2.06), compared with 1 in 1,548 allopurinol users without heart disease (risk ratio = 0.65 per 1,000; 95% CI, 0.50-0.82).
After multivariable analysis, other significant associations with hospital admission included chronic kidney disease (relative risk, 1.88; 95% CI, 1.17-3.02) and an initial allopurinol dosage greater than 100 mg/day (RR, 2.78; 95% CI, 1.75-4.43). In addition, patients with heart disease, chronic kidney disease, and an initial dosage greater than 100 mg/day had an 11-fold higher risk of hospital admission (RR, 11.13; 95% CI, 4.66-26.58).
The authors acknowledged their study’s limitations, including potential misclassification of reactions and comorbidities that can stem from a reliance on ICD codes. However, they also noted that “any misclassification is expected to be nondifferential” and bias results toward the null accordingly.
The study was funded by the Canadian Institutes of Health Research. One author reported receiving a grant from the National Institutes of Health and research support from AstraZeneca, along with consulting fees from Takeda, Selecta Biosciences, and Horizon.

Researchers have found that patients with heart disease have an increased risk of hospitalization for severe cutaneous adverse reactions to allopurinol, with factors like chronic kidney disease and high initial dosage adding to that risk.
“Physicians who prescribe allopurinol should look for these risk factors so that they may consider initiating lower-dosage allopurinol and other precautions, which may prevent this rare but serious adverse reaction,” Chio Yokose, MD, of Massachusetts General Hospital in Boston and coauthors wrote in the Canadian Medical Association Journal.
To further investigate known associations between heart disease and severe cutaneous adverse reactions to allopurinol – including Stevens-Johnson syndrome and toxic epidermal necrolysis – the researchers used an administrative database known as Population Data BC to conduct a cohort study of allopurinol initiators in British Columbia between 1997 and 2015. Individuals with a history of severe cutaneous adverse reactions before starting allopurinol were excluded.
Of the 130,325 allopurinol users identified, 109 were hospitalized for allopurinol-associated severe cutaneous adverse reactions within 3 months of starting the drug. One in 655 allopurinol users with heart disease were admitted to the hospital for allopurinol-associated severe cutaneous adverse reaction (risk ratio = 1.53 per 1,000; 95% confidence interval, 1.10-2.06), compared with 1 in 1,548 allopurinol users without heart disease (risk ratio = 0.65 per 1,000; 95% CI, 0.50-0.82).
After multivariable analysis, other significant associations with hospital admission included chronic kidney disease (relative risk, 1.88; 95% CI, 1.17-3.02) and an initial allopurinol dosage greater than 100 mg/day (RR, 2.78; 95% CI, 1.75-4.43). In addition, patients with heart disease, chronic kidney disease, and an initial dosage greater than 100 mg/day had an 11-fold higher risk of hospital admission (RR, 11.13; 95% CI, 4.66-26.58).
The authors acknowledged their study’s limitations, including potential misclassification of reactions and comorbidities that can stem from a reliance on ICD codes. However, they also noted that “any misclassification is expected to be nondifferential” and bias results toward the null accordingly.
The study was funded by the Canadian Institutes of Health Research. One author reported receiving a grant from the National Institutes of Health and research support from AstraZeneca, along with consulting fees from Takeda, Selecta Biosciences, and Horizon.

Beta-blockers effective, safe for HFrEF with renal dysfunction
PARIS – Beta-blocking drugs were as effective for improving survival in patients with moderately severe renal dysfunction as they were in patients with normal renal function in a meta-analysis of more than 13,000 patients, a finding that seemed to solidify the role for this drug class for essentially all similar heart failure patients, regardless of their renal function.
This evidence could reshape usual care because “renal impairment is often considered a barrier in clinical practice” for starting a beta-blocker drug in patients with heart failure with reduced ejection fraction (HFrEF), Dipak Kotecha, MBChB, said at the annual congress of the European Society of Cardiology.
“We have shown with sufficient sample size that beta-blockers are effective in reducing mortality in patient with HFrEF and in sinus rhythm, even in those with an eGFR [estimated glomerular filtration rate] of 30-44 mL/min per 1.73 m2,” said Dr. Kotecha, a cardiologist at the University of Birmingham (England). “The results suggest that renal impairment should not obstruct the prescription and maintenance of beta-blockers in patients with HFrEF.”
“This important study was a novel attempt to look at [HFrEF] patients with renal insufficiency to see whether they received the same benefit from beta-blockers as other patients, and they did. So renal insufficiency is not a reason to withhold beta-blockers” from these patients, commented Mariell Jessup, MD, a heart failure physician and chief science and medical officer for the American Heart Association in Dallas. “The onus is on clinicians to find a reason not to give a beta-blocker to a patient with HFrEF because they are generally well tolerated and they can have enormous benefit, as we saw in this study,” she said in a video interview.
The analysis run by Dr. Kotecha and associates used data collected in 11 of the pivotal randomized, controlled trial run for beta-blockers during the 1990s and early 2000s, with each study comparing bucindolol, bisoprolol, carvedilol, metoprolol XL, or nebivolol against placebo. The studies collectively enrolled 18,637 patients, which the investigators whittled down in their analysis to 17,433 after excluding patients with a left ventricular ejection fraction below 50% or who were undocumented. The subgroup with HFrEF included 13,861 patient in sinus rhythm at entry, 2,879 with atrial fibrillation, and 693 with an unknown atrial status. The main analysis ran in the 13,861 patients with HFrEF and in sinus rhythm; 14% of this cohort had an eGFR of 30-44 mL/min per 1.73 m2 and 27% had an eGFR of 45-59 mL/min per 1.73 m2. The median age of all patients in the main analysis was 65 years, 23% were women, and their median left ventricular ejection fraction was 27%.
During follow-up of about 3 years, the impact of beta-blocker treatment on survival, compared with placebo, was “substantial” for all strata of patients by renal function, except for those with eGFRs below 30 mL/min per 1.73 m2. (Survival was similar regardless of beta-blocker treatment in the small number of patients with severe renal dysfunction.) The number needed to treat to prevent 1 death in patients with an eGFR of 30-44 mL/min per 1.73 m2 was 21, the same as among patients with an eGFR of 90 mL/min per 1.73 m2 or more, Dr. Kotecha said.
Among the subgroup of patients with atrial fibrillation, beta-blockers appeared to exert no survival benefit, compared with placebo. The investigators did not assess the survival benefits exerted by any individual beta-blocker, compared with the others, and Dr. Kotecha stressed that “my belief is that this is a class effect” and is roughly similar across all the beta-blockers used in the studies.
The analysis also showed good safety and tolerability of the beta-blockers in patients with renal dysfunction. The incidence of adverse events leading to treatment termination was very similar in the beta-blocker and placebo arms, and more than three-quarters of patients in each of the two subgroups with renal dysfunction were maintained on more than 50% of their target beta-blocker dosage.
Dr. Kotecha has been an advisor to Bayer, a speaker on behalf of Atricure, and has received research funding from GlaxoSmithKline and Menarini. Dr. Jessup had no disclosures.
This analysis of individual patient data is very important and extends our knowledge. The results confirm that beta-blocker treatment reduces mortality in patients with heart failure with reduced ejection fraction (HFrEF) and in sinus rhythm who also have moderately severe renal dysfunction with an estimated glomerular filtration rate as low as 30-44 mL/min per 1.73 m2. This is good news for patients with HFrEF and kidney disease. Clinicians often use comorbidities as a reason not to prescribe or up-titrate beta-blockers. These results show that beta-blockers can be used at guideline-directed dosages, even in patients with renal dysfunction. The findings highlight the importance of not looking for excuses to not treat patients with a beta-blocker. Do not worry about renal function.

Machine learning–derived risk score predicts heart failure risk in diabetes patients
PHILADELPHIA – For patients with high-risk diabetes, a novel, machine learning–derived risk score based on 10 common clinical variables can identify those facing a heart failure risk of up to nearly 20% over the ensuing 5 years, an investigator said at the annual meeting of the Heart Failure Society of America.
The risk score, dubbed WATCH-DM, has greater accuracy in predicting incident heart failure than traditional risk-based models, and requires no specific cardiovascular biomarkers or imaging, according to Muthiah Vaduganathan, MD, MPH, a cardiologist at Brigham and Women’s Hospital and faculty at Harvard Medical School in Boston.
The tool may help inform risk-based monitoring and introduction of sodium-glucose transporter 2 (SGLT2) inhibitors, which have been shown in multiple clinical trials to prevent heart failure in at-risk patients with type 2 diabetes mellitus (T2DM), Dr. Vaduganathan said.
“Patients identified at high risk based on WATCH-DM should be strongly considered for initiation of SGLT2 inhibitors in clinical practice,” Dr. Vaduganathan said in an interview.
WATCH-DM is available online at cvriskscores.com. Work is underway to integrate the tool into electronic health record systems at Brigham and Women’s Hospital and at the University of Texas Southwestern Medical Center in Dallas. “I expect that to be launched in the next year,” he said.
The WATCH-DM score was developed based on data from the ACCORD (Action to Control Cardiovascular Risk in Diabetes) trial, including 8,756 T2DM patients with inadequate glycemic control at high cardiovascular risk and no heart failure at baseline.
Starting with 147 variables, the investigators used a decision-tree machine learning approach to identify predictors of heart failure.
“What machine learning does is automate the variable selection process, as a form of artificial intelligence,” Dr. Vaduganathan said.
The WATCH-DM risk score was based on the 10 best-performing predictors as selected by machine learning, including body mass index, age, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, serum creatinine, high-density lipoprotein cholesterol, QRS duration, prior myocardial infarction, and prior coronary artery bypass grafting.
The 5-year risk of heart failure was just 1.1% for patients with WATCH-DM scores in the lowest quintile, increasing in a graded fashion to nearly 20% (17.4%) in the highest quintile, study results show.
Findings of the study were simultaneously published in the journal Diabetes Care.
Dr. Vaduganathan said he is supported by an award from Harvard Catalyst. He provided disclosures related to Amgen, AstraZeneca, Baxter Healthcare, Bayer AG, Boehringer Ingelheim (advisory boards), and with Novartis and the National Institutes of Health (participation on clinical endpoint committees).

Drug abuse–linked infective endocarditis spiking in U.S.
Hospitalizations for infective endocarditis associated with drug abuse doubled in the United States from 2002 to 2016, in a trend investigators call “alarming,” and link to a concurrent rise in opioid abuse.
Patients tend to be younger, poorer white males, according to findings published online in the Journal of the American Heart Association.
For their research, Amer N. Kadri, MD, of the Cleveland Clinic and colleagues looked at records for nearly a million hospitalizations for infective endocarditis (IE) in the National Inpatient Sample registry. All U.S. regions saw increases in drug abuse–linked cases of IE as a share of IE hospitalizations. Incidence of drug abuse–associated IC rose from 48 cases/100,000 population in 2002 to 79/100,000 in 2016. The Midwest saw the highest rate of change, with an annual percent increase of 4.9%.
While most IE hospitalizations in the study cohort were of white men (including 68% for drug-linked cases), the drug abuse–related cases were younger (median age, 38 vs. 70 years for nondrug-related IE), and more likely male (55.5% vs. 50%). About 45% of the drug-related cases were in people receiving Medicaid, and 42% were in the lowest quartile of median household income.
The drug abuse cases had fewer renal and cardiovascular comorbidities, compared with the nondrug cases, but were significantly more likely to present with HIV, hepatitis C, alcohol abuse, and liver disease. Inpatient mortality was lower among the drug-linked cases – 6% vs. 9% – but the drug cases saw significantly more cardiac or valve surgeries, longer hospital stays, and higher costs.
“Hospitalizations for IE have been increasing side by side with the opioid epidemic,” the investigators wrote in their analysis. “The opioid crisis has reached epidemic levels, and now drug overdoses have been the leading cause of injury-related death in the U.S. Heroin deaths had remained relatively low from 1999 until 2010 whereas it then increased threefold from 2010-2015.” The analysis showed a rise in drug abuse–associated IE “that corresponds to this general period.” The findings argue, the investigators said, for better treatment for opioid addiction after hospitalization and greater efforts to make drug rehabilitation available after discharge. The researchers described as a limitation of their study the use of billing codes that changed late in the study period, increasing detection of drug abuse cases after 2015. They reported no outside funding or conflicts of interest.

The drug abuse cases had fewer renal and cardiovascular comorbidities, compared with the nondrug cases, but were significantly more likely to present with HIV, hepatitis C, alcohol abuse, and liver disease. Inpatient mortality was lower among the drug-linked cases – 6% vs. 9% – but the drug cases saw significantly more cardiac or valve surgeries, longer hospital stays, and higher costs.
“Hospitalizations for IE have been increasing side by side with the opioid epidemic,” the investigators wrote in their analysis. “The opioid crisis has reached epidemic levels, and now drug overdoses have been the leading cause of injury-related death in the U.S. Heroin deaths had remained relatively low from 1999 until 2010 whereas it then increased threefold from 2010-2015.” The analysis showed a rise in drug abuse–associated IE “that corresponds to this general period.” The findings argue, the investigators said, for better treatment for opioid addiction after hospitalization and greater efforts to make drug rehabilitation available after discharge. The researchers described as a limitation of their study the use of billing codes that changed late in the study period, increasing detection of drug abuse cases after 2015. They reported no outside funding or conflicts of interest.

Hospitalizations for infective endocarditis associated with drug abuse doubled in the United States from 2002 to 2016, in a trend investigators call “alarming,” and link to a concurrent rise in opioid abuse.
Patients tend to be younger, poorer white males, according to findings published online in the Journal of the American Heart Association.
For their research, Amer N. Kadri, MD, of the Cleveland Clinic and colleagues looked at records for nearly a million hospitalizations for infective endocarditis (IE) in the National Inpatient Sample registry. All U.S. regions saw increases in drug abuse–linked cases of IE as a share of IE hospitalizations. Incidence of drug abuse–associated IC rose from 48 cases/100,000 population in 2002 to 79/100,000 in 2016. The Midwest saw the highest rate of change, with an annual percent increase of 4.9%.
