Overview

Diastolic heart failure is one of the examples of heart failure with preserved ejection fraction. Other causes that cause heart failure and do not affect ejection fraction need to be differentiated from this condition.

Differential Diagnosis

Differentiation of Diastolic Dysfunction from Systolic Dysfunction

Characteristics of systolic dysfunction:
- Large, dilated, eccentrically hypertrophied ventricles
- Impaired blood ejection during systole
- Decreased cardiac output and ejection fraction
- Normal or decreased blood pressure
- Can occur in any age and more frequent in men than in women
- Presence of S3 gallop
Characteristics of diastolic dysfunction:
- Small, thickened, concentrically hypertrophied ventricles
- Impaired blood filling during diastole
- Normal ejection fraction
- Systemic elevation of the blood pressure
- Occurs mainly in elderly women
- Presence of S4 gallop ^[1]
