BACKGROUND: The RALES trial demonstrated that spironolactone improved the prognosis of patients with heart failure (HF). However, it is unknown whether the discharge use of spironolactone is associated with better long-term outcomes among hospitalized systolic HF patients in routine clinical practice. We examined the effects of spironolactone use at discharge on mortality and rehospitalization by comparing with outcomes in patients who did not receive spironolactone. METHODS: The JCARE-CARD studied prospectively the characteristics and treatments in a broad sample of patients hospitalized with worsening HF and the outcomes were followed with an average of 2.2 years of follow-up. RESULTS: A total of 946 patients had HF with reduced left ventricular ejection fraction (LVEF) (<40%), among whom spironolactone was prescribed at discharge in 435 patients (46%), but not in 511 patients (54%). The mean age was 66.3 years and 72.2% were male. Etiology was ischemic in 39.7% and mean LVEF was 27.1%. After adjustment for covariates, discharge use of spironolactone was associated with a significant reduction in all-cause death (adjusted hazard ratio 0.612, P=.020) and cardiac death (adjusted hazard ratio 0.524, P=.013). CONCLUSIONS: Among patients with HF hospitalized for systolic dysfunction, spironolactone use at the time of discharge was associated with long-term survival benefit. These findings provide further support for the idea that spironolactone may be useful in patients hospitalized with HF and reduced LVEF. Copyright (c) 2010 Mosby, Inc. All rights reserved.
