Background—The contributions of risk factors and disease pathogenesis to heart failure with
preserved ejection fraction (HFPEF) versus heart failure with reduced ejection fraction …

Aims We assessed the clinical characteristics and prognosis of chronic heart failure patients
with improved ejection fraction (HFIEF) compared with persistently reduced ejection fraction …

Objectives: This study sought to evaluate the incidence, the predictors, and the associations
with outcomes of changes in ejection fraction (EF) in heart failure (HF) patients. Background …

Importance Adoption of guideline-directed medical therapy for patients with heart failure is
variable. Interventions to improve guideline-directed medical therapy have failed to …

BACKGROUND: The influence of patient age and sex on delivery of guideline-
recommended heart failure (HF) therapies in contemporary outpatient settings has not been …

Importance Patients categorized as having heart failure (HF) with left ventricular ejection
fraction (LVEF) in the midrange between 40% and 50%(HFmrEF) are known to be at …

Background—Patients with heart failure (HF) are typically designated as having reduced or
preserved ejection fraction (HFREF, HFPEF) because of the importance of left ventricular …

The clinical syndrome comprising heart failure (HF) symptoms but with a left ventricular
ejection fraction (EF) that is not diminished, eg, HF with preserved EF, is increasingly the …

HEART FAILURE (HF) IS A MAJOR PUBLIC HEALTH PROB-lem, with a prevalence of more
than 5 million cases and an incidence of 660 000 new cases per year in the United States …

Despite use of similar drugs, outcomes of recent heart failure (HF) trials were frequently
neutral in heart failure with normal left ventricular ejection fraction (HFNEF) and positive in …
