Sex Differences in Clinical Course and Patient-Reported Outcomes Among Patients Hospitalized for Heart Failure

Abstract Objectives The goal of this study was to evaluate differences in clinical and patient-reported outcomes between women and men hospitalized for acute HF. Background Among patients hospitalized for heart failure (HF), it is unclear if symptom burden, response to therapy, and patient-reported quality of life (QOL) are different in women as compared with men. Methods The ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) trial randomized 7,141 patients hospitalized for HF with reduced or preserved ejection fraction (EF) to receive nesiritide or placebo in addition to standard care. Clinical endpoints included 30-day mortality and rehospitalization and 180-day mortality. Patient-reported QOL was assessed at baseline, discharge, and 30 days using the EuroQOL 5 dimensions (EQ-5D) survey. Results Among 7,141 total patients, 4,697 (65.8%) were men and 2,444 (34.2%) were women. Among patients with EF ≤40%, women were less likely to receive angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker and beta-blocker therapy, and less likely to have an implantable cardioverter-defibrillator (all p  0.05), but women experienced less in-hospital weight loss and urine output (all p  Conclusions In this acute HF population, women had similar risk of mortality and rehospitalization as compared with men, but experienced worse patient-reported QOL during and after hospitalization that persisted after adjustment for demographic and clinical factors. Current acute HF management may work similarly in either sex for purposes of preventing clinical events, but may be less equipped to improve patient-reported outcomes in women as compared with men.
