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
- Large atria
- 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]
Differentiation of Diastolic Dysfunction from other Medical Conditions
- Right heart failure
- Valvular heart disease
- Pericardial diseases - constrictive pericarditis, cardiac tamponade
- Cardiac tumors
- High output cardiac failure
