diastolic heart failure
Heart failure with preserved ejection fraction caused by impaired ventricular relaxation and filling.
Full Definition
Diastolic heart failure, also known as heart failure with preserved ejection fraction (HFpEF), occurs when the left ventricle maintains normal systolic function but has impaired relaxation and filling during diastole. This results in elevated filling pressures and reduced cardiac output despite preserved ejection fraction. The condition is often associated with left ventricular hypertrophy, hypertension, diabetes, and aging. Diagnosis requires clinical signs of heart failure with normal or near-normal ejection fraction and evidence of diastolic dysfunction.
Usage
Usage note: Prefer 'heart failure with preserved ejection fraction' in formal documentation.
