Two Phenotypes, One Prognosis: Period-Specific Mortality and Prediction of Post-Discharge Events in Acute Heart Failure
Background: The prognostic relevance of left ventricular ejection fraction (LVEF) categories in acute heart failure (AHF) remains debated. We compared the clinical phenotype of patients hospitalized for AHF with preserved (LVEF ≥ 50%) versus reduced (LVEF < 50%) ejection fraction (EF), and compared the prognostic influ...
