Background And Objectives: An improvement in left ventricular ejection fraction (LVEF) in patients with heart failure (HF) is associated with a better prognosis. Identifying these subjects early after an episode of decompensation, the necessary threshold of LVEF improvement, and its predictive factors are of great interest.
Patients And Methods: One hundred and ten patients hospitalized for HF were prospectively reassessed at an early outpatient visit (mean of 38 days).
