Worsening heart failure during hospitalization for acute heart failure: Insights from the Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND-HF).

ABSTRACT: Despite initial in-hospital treatment of acute heart failure (HF), some patients experience worsening HF (WHF). There are limited data about the outcomes and characteristics of patients who experience in-hospital WHF.We assessed the characteristics and outcomes of patients with and without WHF in the ASCEND-HF trial. Worsening HF was defined as at least 1 symptom or sign of new, persistent, or WHF requiring additional intravenous inotropic/vasodilator or mechanical therapy during index hospitalization. We assessed the relationship between WHF and 30-day mortality, 30-day mortality or HF hospitalization, and 180-day mortality. We also assessed whether there was a differential association between early (days 1-3) vs late (day ?4) WHF and outcomes. Of 7,141 patients with acute HF, 354 (5%) experienced WHF. Patients with WHF were more often male and had a history of atrial fibrillation or diabetes, lower blood pressure, and higher creatinine. After risk adjustment, WHF was associated with increased 30-day mortality (odds ratio 13.37, 95% CI 9.85-18.14), 30-day mortality or HF rehospitalization (odds ratio 6.78, 95% CI 5.25-8.76), and 180-day mortality (hazard ratio 3.90, 95% CI 3.14-4.86) (all P values < .0001). There was no evidence of a difference in outcomes between early and late WHF (all P values for comparison ? .2).Worsening HF during index hospitalization was associated with worse 30- and 180-day outcomes. Worsening HF may represent an important patient-centered outcome in acute HF and a focus of future treatments.

Project description:BackgroundOutcomes associated with episodes of hypotension while hospitalized with acute decompensated heart failure are not well understood.Methods and resultsUsing data from Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND-HF), we assessed factors associated with in-hospital hypotension and subsequent 30-day outcomes. Patients were classified as having symptomatic or asymptomatic hypotension. Multivariable logistic regression was used to determine factors associated with in-hospital hypotension, and Cox proportional hazards models were used to assess the association between hypotension and 30-day outcomes. We also tested for treatment interaction with nesiritide on 30-day outcomes and the association between in-hospital hypotension and renal function at hospital discharge. Overall, 1555 of 7141 (21.8%) patients had an episode of hypotension, of which 73.1% were asymptomatic and 26.9% were symptomatic. Factors strongly associated with in-hospital hypotension included randomization to nesiritide (odds ratio, 1.98; 95% confidence interval [CI], 1.76-2.23; P<0.001), chronic metolazone therapy (odds ratio, 1.74; 95% CI, 1.17-2.60; P<0.001), and baseline orthopnea (odds ratio, 1.31; 95% CI, 1.13-1.52; P=0.001) or S3 gallop (odds ratio, 1.21; 95% CI, 1.06-1.40; P=0.006). In-hospital hypotension was associated with increased hazard of 30-day mortality (hazard ratio, 2.03; 95% CI, 1.57-2.61; P<0.001), 30-day heart failure hospitalization or mortality (hazard ratio, 1.58; 95% CI, 1.34-1.86; P<0.001), and 30-day all-cause hospitalization or mortality (hazard ratio, 1.40; 95% CI, 1.22-1.61; P<0.001). Nesiritide had no interaction on the relationship between hypotension and 30-day outcomes (interaction P=0.874 for death, P=0.908 for death/heart failure hospitalization, P=0.238 death/all-cause hospitalization).ConclusionsHypotension while hospitalized for acute decompensated heart failure is an independent risk factor for adverse 30-day outcomes, and its occurrence highlights the need for modified treatment strategies.Clinical trial registration urlhttp://www.clinicaltrials.gov.

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.
