The clinical quandary of left and right ventricular diastolic dysfunction and diastolic heart failure

Area of Science:

• Cardiology
• Heart Failure Research

Background:

• Diastolic heart failure (DHF) is clinically similar to systolic heart failure (SHF) without direct left ventricular (LV) function assessment.
• DHF is diagnosed in patients with heart failure signs/symptoms but preserved LV function and ejection fraction (EF).
• Commonly associated with hypertension or infiltrative cardiac diseases, DHF contrasts with diastolic dysfunction, a mechanical LV relaxation issue diagnosed via echocardiography.

Purpose of the Study:

• To critically review the progression of diastolic dysfunction to diastolic heart failure.
• To analyze current treatment strategies for diastolic heart failure.
• To assess available data on diastolic dysfunction progression to systolic heart failure.

Main Methods:

• Literature review and critical analysis of existing data.
• Examination of diagnostic criteria for diastolic dysfunction and diastolic heart failure.
• Review of treatment recommendations and reported outcomes.

Main Results:

• Diastolic dysfunction is a mechanical abnormality of LV relaxation, distinct from clinical diastolic heart failure.
• Diastolic heart failure is characterized by heart failure symptoms with preserved ejection fraction.
• Current treatment focuses on risk reduction and symptom management; data on progression to systolic heart failure is limited.

Conclusions:

• Distinguishing diastolic heart failure from systolic heart failure requires direct assessment of left ventricular function.
• Diastolic dysfunction, a mechanical issue, may not always manifest as clinical heart failure.
• Further research is needed on the progression of diastolic dysfunction to systolic heart failure and its management.
