Diastolic heart failure: a review and primary care perspective

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Diastolic heart failure (DHF) is now a recognized distinct entity.
• DHF is highly prevalent, especially in elderly populations, often exceeding systolic heart failure (SHF) incidence.
• Both DHF and SHF contribute to substantial morbidity, mortality, and healthcare costs.

Purpose of the Study:

• To review the current understanding of diastolic heart failure.
• To emphasize evidence-based management approaches for DHF.
• To provide guidance for primary care physicians managing DHF patients.

Main Methods:

• Review of existing literature on DHF pathophysiology and treatment.
• Analysis of clinical trial data, though limited for isolated DHF.
• Synthesis of current concepts and clinical experience in DHF management.

Main Results:

• Consensus confirms DHF as a distinct heart failure type.
• DHF is epidemiologically significant, particularly in older adults.
• Treatment primarily relies on pathophysiology understanding and SHF experience due to limited DHF-specific trials.

Conclusions:

• DHF diagnosis is primarily clinical, with limited supporting data.
• Prognosis and treatment differ between diastolic and systolic heart failure.
• This review focuses on evidence-based management for primary care physicians.
