Diastolic heart failure: perception of the syndrome and scope of the problem

Area of Science:

• Cardiology
• Heart Failure Research

Background:

• Recent clinical trials like CHARM-Preserved have spurred new questions regarding heart failure with preserved ejection fraction (HFpEF).
• Numerous ongoing trials, including I-PRESERVE, are investigating HFpEF, highlighting its clinical significance.
• Understanding the conceptual rationale and pathophysiological basis of HFpEF is crucial for advancing treatment strategies.

Purpose of the Study:

• To provide a synopsis of the key controversies surrounding diastolic heart failure (HFpEF).
• To address the conceptual and pathophysiological questions arising from recent and ongoing HFpEF clinical trials.
• To summarize the current understanding and identify remaining knowledge gaps in HFpEF.

Main Methods:

• Review of recent clinical trial publications (e.g., CHARM-Preserved).
• Analysis of ongoing clinical trials (e.g., I-PRESERVE) in patients with preserved left ventricular ejection fraction.
• Synthesis of expert contributions and identification of key controversies in the field.

Main Results:

• Significant questions persist regarding the fundamental understanding of diastolic heart failure.
• The pathophysiological basis of HFpEF remains a subject of active investigation and debate.
• Ongoing research aims to refine diagnostic criteria and therapeutic approaches for HFpEF.

Conclusions:

• Diastolic heart failure (HFpEF) represents a significant and complex clinical problem.
• Further research and clinical trials are essential to elucidate the pathophysiology and improve management of HFpEF.
• Addressing current controversies is vital for advancing the care of patients with HFpEF.
