A Canadian context for the Acute Study of Clinical Effectiveness of Nesiritide and Decompensated Heart Failure (ASCEND-HF) trial.

ABSTRACT: Congestive heart failure comprises a major public health problem destined to grow enormously over the next decade. Paradoxically, and in contrast to acute coronary disease, acute heart failure has been relatively understudied. Current standards of care involve the use of intravenous diuretics and vasodilators; inotropic agents have been restricted to in-hospital use because of concern about their potential harmful effects. The emergence of recombinant human B-type natriuretic peptide (BNP) provides an interesting therapeutic alternative because of its capacity to promote vasodilation as well as increase salt and water excretion, and improve pulmonary congestion by reducing left ventricular filling pressure. This agent will be explored in the Acute Study of Clinical Effectiveness of Nesiritide and Decompensated Heart Failure (ASCEND-HF), the largest ever trial conducted in acute decompensated heart failure. Patients will be studied through day 30 with end points of all-cause mortality in rehospitalization as the primary composite outcome. A variety of mechanistic substudies are planned as well as an assessment of the health care economic implications of acute heart failure and the pathophysiological elements hypothesized to modulate the expected treatment effect examined. The trial is embedded in an academic research organization motif and promises to provide a significant contribution to the body of knowledge in acute heart failure and the care of patients so afflicted.

Project description:BackgroundCongestion is the most frequent cause for hospitalization in acute decompensated heart failure. Although decongestion is a major goal of acute therapy, it is unclear how the clinical components of congestion (eg, peripheral edema, orthopnea) contribute to outcomes after discharge or how well decongestion is maintained.Methods and resultsA post hoc analysis was performed of 496 patients enrolled in the Diuretic Optimization Strategy Evaluation in Acute Decompensated Heart Failure (DOSE-AHF) and Cardiorenal Rescue Study in Acute Decompensated Heart Failure (CARRESS-HF) trials during hospitalization with acute decompensated heart failure and clinical congestion. A simple orthodema congestion score was generated based on symptoms of orthopnea (≥2 pillows=2 points, <2 pillows=0 points) and peripheral edema (trace=0 points, moderate=1 point, severe=2 points) at baseline, discharge, and 60-day follow-up. Orthodema scores were classified as absent (score of 0), low-grade (score of 1-2), and high-grade (score of 3-4), and the association with death, rehospitalization, or unscheduled medical visits through 60 days was assessed. At baseline, 65% of patients had high-grade orthodema and 35% had low-grade orthodema. At discharge, 52% patients were free from orthodema at discharge (score=0) and these patients had lower 60-day rates of death, rehospitalization, or unscheduled visits (50%) compared with those with low-grade or high-grade orthodema (52% and 68%, respectively; P=0.038). Of the patients without orthodema at discharge, 27% relapsed to low-grade orthodema and 38% to high-grade orthodema at 60-day follow-up.ConclusionsIncreased severity of congestion by a simple orthodema assessment is associated with increased morbidity and mortality. Despite intent to relieve congestion, current therapy often fails to relieve orthodema during hospitalization or to prevent recurrence after discharge.Clinical trial registrationURL: http://www.clinicaltrials.gov.

Project description:ImportanceIt remains unclear whether telemonitoring approaches provide benefits for patients with heart failure (HF) after hospitalization.ObjectiveTo evaluate the effectiveness of a care transition intervention using remote patient monitoring in reducing 180-day all-cause readmissions among a broad population of older adults hospitalized with HF.Design, setting, and participantsWe randomized 1437 patients hospitalized for HF between October 12, 2011, and September 30, 2013, to the intervention arm (715 patients) or to the usual care arm (722 patients) of the Better Effectiveness After Transition-Heart Failure (BEAT-HF) study and observed them for 180 days. The dates of our study analysis were March 30, 2014, to October 1, 2015. The setting was 6 academic medical centers in California. Participants were hospitalized individuals 50 years or older who received active treatment for decompensated HF.InterventionsThe intervention combined health coaching telephone calls and telemonitoring. Telemonitoring used electronic equipment that collected daily information about blood pressure, heart rate, symptoms, and weight. Centralized registered nurses conducted telemonitoring reviews, protocolized actions, and telephone calls.Main outcomes and measuresThe primary outcome was readmission for any cause within 180 days after discharge. Secondary outcomes were all-cause readmission within 30 days, all-cause mortality at 30 and 180 days, and quality of life at 30 and 180 days.ResultsAmong 1437 participants, the median age was 73 years. Overall, 46.2% (664 of 1437) were female, and 22.0% (316 of 1437) were African American. The intervention and usual care groups did not differ significantly in readmissions for any cause 180 days after discharge, which occurred in 50.8% (363 of 715) and 49.2% (355 of 722) of patients, respectively (adjusted hazard ratio, 1.03; 95% CI, 0.88-1.20; P = .74). In secondary analyses, there were no significant differences in 30-day readmission or 180-day mortality, but there was a significant difference in 180-day quality of life between the intervention and usual care groups. No adverse events were reported.Conclusions and relevanceAmong patients hospitalized for HF, combined health coaching telephone calls and telemonitoring did not reduce 180-day readmissions.Trial registrationclinicaltrials.gov Identifier: NCT01360203.

Project description:ImportancePersistent congestion is associated with worse outcomes in acute heart failure (AHF). Mineralocorticoid receptor antagonists administered at high doses may relieve congestion, overcome diuretic resistance, and mitigate the effects of adverse neurohormonal activation in AHF.ObjectiveTo assess the effect of high-dose spironolactone and usual care on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels compared with usual care alone.Design, setting, and participantsThis double-blind and placebo (or low-dose)-controlled randomized clinical trial was conducted in 22 US acute care hospitals among patients with AHF who were previously receiving no or low-dose (12.5 mg or 25 mg daily) spironolactone and had NT-proBNP levels of 1000 pg/mL or more or B-type natriuretic peptide levels of 250 pg/mL or more, regardless of ejection fraction.InterventionsHigh-dose spironolactone (100 mg) vs placebo or 25 mg spironolactone (usual care) daily for 96 hours.Main outcomes and measuresThe primary end point was the change in NT-proBNP levels from baseline to 96 hours. Secondary end points included the clinical congestion score, dyspnea assessment, net urine output, and net weight change. Safety end points included hyperkalemia and changes in renal function.ResultsA total of 360 patients were randomized, of whom the median age was 65 years, 129 (36%) were women, 200 (55.5%) were white, 151 (42%) were black, 8 (2%) were Hispanic or Latino, 9 (2.5%) were of other race/ethnicity, and the median left ventricular ejection fraction was 34%. Baseline median (interquartile range) NT-proBNP levels were 4601 (2697-9596) pg/mL among the group treated with high-dose spironolactone and 3753 (1968-7633) pg/mL among the group who received usual care. There was no significant difference in the log NT-proBNP reduction between the 2 groups (-0.55 [95% CI, -0.92 to -0.18] with high-dose spironolactone and -0.49 [95% CI, -0.98 to -0.14] with usual care, P = .57). None of the secondary end point or day-30 all-cause mortality or heart failure hospitalization rate differed between the 2 groups. The changes in serum potassium and estimated glomerular filtration rate at 24, 48, 72, and 96 hours. were similar between the 2 groups.Conclusions and relevanceAdding treatment with high-dose spironolactone to usual care for patients with AHF for 96 hours was well tolerated but did not improve the primary or secondary efficacy end points.Trial registrationclinicaltrials.gov Identifier: NCT02235077.

Project description:OBJECTIVES:This study sought to assess a novel physical rehabilitation intervention in older patients hospitalized for acute decompensated heart failure (ADHF). BACKGROUND:After ADHF, older patients, who are frequently frail with multiple comorbidities, have prolonged and incomplete recovery of physical function and remain at high risk for poor outcomes. METHODS:The REHAB-HF (Rehabilitation Therapy in Older Acute Heart Failure Patients) pilot study was a 3-site, randomized, attention-controlled pilot study of a tailored, progressive, multidomain physical rehabilitation intervention beginning in the hospital and continuing for 12 weeks post-discharge in patients ?60 years hospitalized with ADHF. The primary purpose was to assess the feasibility and reasonableness of the hypothesis that the novel rehabilitation intervention would improve physical function (Short Physical Performance Battery [SPPB]) over 3 months and reduce all-cause rehospitalizations over 6 months. RESULTS:The study enrolled 27 patients with ADHF (ages 60 to 98 years; 59% women; 56% African American; 41% with preserved ejection fraction [?45%]). At baseline, participants had marked impairments in physical function, multiple comorbidities, and frailty. Study retention (89%) and intervention adherence (93%) were excellent. At 3 months, an intervention effect size was measured for the SPPB score of +1.1 U (7.4 ± 0.5 U vs. 6.3 ± 0.5 U), and at 6 months an effect size was observed for an all-cause rehospitalization rate of -0.48 (1.16 ± 0.35 vs. 1.64 ± 0.39). The change in SPPB score was strongly related to all-cause rehospitalizations, explaining 91% of change. CONCLUSIONS:These findings support the feasibility and rationale for a recently launched, National Institutes of Health-funded trial to test the safety and efficacy of this novel multidomain physical rehabilitation intervention to improve physical function and reduce rehospitalizations in older, frail patients with ADHF with multiple comorbidities.

Project description:ImportanceIn PIONEER-HF, among stabilized patients with acute decompensated heart failure (ADHF), the in-hospital initiation of sacubitril/valsartan was well tolerated and led to improved outcomes compared with enalapril. However, there are limited data comparing the strategies of in-hospital vs postdischarge initiation of sacubitril/valsartan.ObjectiveTo describe changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in patients recently hospitalized for ADHF and switching from taking enalapril to taking sacubitril/valsartan after discharge and compare clinical outcomes for patients randomized to receive in-hospital initiation of sacubitril/valsartan vs in-hospital initiation of enalapril who later switched to taking sacubitril/valsartan during an open-label extension phase.InterventionsSacubitril/valsartan titrated to 97/103 mg twice daily.Design, setting, and participantsThe PIONEER-HF trial was a multicenter, randomized, double-blind, active-controlled trial conducted at 129 US sites between May 2016 and May 2018 that compared the in-hospital initiation of sacubitril/valsartan vs enalapril (titrated to target dose, 10 mg twice daily) for 8 weeks among patients admitted for ADHF with reduced ejection fraction and hemodynamic stability. All patients were to continue in a 4-week, open-label study of sacubitril/valsartan; of 881 patients enrolled in PIONEER-HF, 832 (94%) continued in the open-label study.Main outcomes and measuresChanges in NT-proBNP levels from week 8 to 12 as well as the exploratory composite of heart failure rehospitalization or cardiovascular death from randomization through week 12.ResultsOf 881 participants, 226 (27.7%) were women, 487 (58.5%) were white, 297 (35.7%) were black, 15 (1.8%) were Asian, and 73 (8.8%) were of Hispanic ethnicity; the mean (SD) age was 61 (14) years. For patients who continued to take sacubitril/valsartan, NT-proBNP levels declined -17.2% (95% CI, -3.2 to -29.1) from week 8 to 12. The NT-proBNP levels declined to a greater extent for those switching from taking enalapril to sacubitril/valsartan after the week 8 visit (-37.4%; 95% CI, -28.1 to -45.6; P < .001; comparing changes in 2 groups). Over the entire 12 weeks of follow-up, patients that began taking sacubitril/valsartan in the hospital had a lower hazard for the composite outcome compared with patients that initiated enalapril in the hospital and then had a delayed initiation of sacubitril/valsartan 8 weeks later (hazard ratio, 0.69; 95% CI 0.49-0.97).Conclusions and relevanceSwitching patients' treatment from enalapril to sacubitril/valsartan at 8 weeks after randomization led to a further 37% reduction in NT-proBNP levels in patients with heart failure with reduced ejection fraction and a recent hospitalization for ADHF.Trial registrationClinicalTrials.gov identifier: NCT02554890.
