The Heart Failure with Preserved Ejection Fraction Conundrum-Redefining the Problem and Finding Common Ground?

Area of Science:

• Cardiology
• Heart Failure Research

Background:

• Heart failure with preserved ejection fraction (HFpEF), also known as diastolic heart failure (DHF), constitutes over 50% of congestive heart failure (CHF) cases.
• The increasing elderly population is projected to drive an epidemic rise in HFpEF, escalating healthcare costs and straining infrastructure.
• Unlike systolic heart failure (SHF), HFpEF presents significant uncertainties regarding risk factors, pathophysiology, and effective treatment monitoring.

Purpose of the Study:

• To review current understanding and recent advancements in the field of HFpEF.
• To highlight the limitations in diagnosing and managing HFpEF compared to SHF.
• To provide perspective on emerging trends and future directions in HFpEF research.

Main Methods:

• Review of recent epidemiological observations and guideline changes.
• Analysis of diagnostic tools, including the role of exercise diastolic stress testing.
• Evaluation of current therapeutic strategies and their limitations in HFpEF.

Main Results:

• Existing guidelines for HFpEF rely heavily on general symptoms and static echocardiographic parameters.
• The exercise diastolic stress test offers a more dynamic assessment and warrants increased clinical focus.
• Current therapeutic options for HFpEF are largely extrapolated from SHF without specific prognostic data.

Conclusions:

• HFpEF represents a growing clinical challenge with evolving diagnostic and therapeutic landscapes.
• Further research is essential to clarify risk factors, pathophysiology, and develop effective, evidence-based treatments for HFpEF.
• The field anticipates significant advancements and new thinking in HFpEF management over the next decade.
