BACKGROUND: Available data suggest that improvement in left ventricular ejection fraction
(LVEF) is a major predictor of improved survival in heart failure (HF). Although certain factors …

Background: Among patients with heart failure (HF) with reduced ejection fraction (EF),
improvements in left ventricular EF (LVEF) are associated with better outcomes and remain …

Background Many patients with heart failure (HF) with reduced ejection fraction (HF r EF)
experience improvement or recovery of left ventricular ejection fraction (LVEF). Data on …

Importance Heart failure (HF) guidelines recognize that a subset of patients with HF and
preserved left ventricular ejection fraction (LVEF) previously had reduced LVEF but …

Background—Randomized trials have demonstrated the efficacy of several new therapies
for heart failure (HF) with reduced ejection fraction over the preceding 2 decades. This study …

Background—Heart failure with recovered or improved ejection fraction (HFiEF) has been
proposed as a new category of HF. Whether HFiEF is clinically distinct from HF with …

Background—About one half of patients with heart failure (HF) have preserved ejection
fraction (HFPEF) rather than reduced ejection fraction (HFREF). The differences in risk …

Background: Epidemiology of patients with worsening heart failure and reduced ejection
fraction (HFrEF) in the real-world setting is not well described. Objectives: The purpose of …

stolic dysfunction, preserved systolic function). Infiltrative processes, toxic causes, infections
of the myocardium, and systemic conditions, such as collagen vascular diseases with …

Objectives: The aim of this study was to assess the prognostic importance of left ventricular
ejection fraction (LVEF) in stable outpatients with heart failure (HF). Background: Although …
