heart failure with preserved ejection fraction
Also written as: HFpEF — heart failure with preserved ejection fraction
A type of heart failure where the heart's pumping function appears normal but filling is impaired, also known as diastolic heart failure.
Full Definition
Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome characterized by symptoms and signs of heart failure in the presence of a normal or near-normal left ventricular ejection fraction (typically ≥50%). Previously termed diastolic heart failure, HFpEF results from impaired ventricular relaxation and increased filling pressures rather than reduced contractility. The condition is increasingly common, particularly in elderly patients with hypertension, diabetes, and obesity. Diagnosis requires evidence of elevated filling pressures through echocardiography, cardiac catheterization, or elevated natriuretic peptides, as standard imaging may appear deceptively normal.
Usage
Usage note: Prefer 'HFpEF' over outdated 'diastolic heart failure' in contemporary documentation.
