heart failure with preserved ejection fraction

Full Definition

A form of heart failure characterized by symptoms and signs of heart failure but with preserved left ventricular systolic function, typically defined as ejection fraction ≥50%. Patients with HFpEF present unique challenges in cardiac rehabilitation due to diastolic dysfunction, exercise intolerance, and different response patterns to exercise training. Exercise prescription requires careful attention to volume status, filling pressures, and symptom monitoring.

Usage

Usage note: Distinguish from HFrEF (reduced ejection fraction); exercise responses differ between these conditions.

In Context

• "The HFpEF patient required modified exercise protocols due to diastolic dysfunction." — Treatment plan
• "Exercise training benefits in heart failure with preserved ejection fraction focus on functional improvement rather than mortality reduction." — Clinical guideline
