Coronary Microvascular Dysfunction and Heart Failure with Preserved Ejection Fraction - implications for Chronic Inflammatory Mechanisms

Area of Science:

• Cardiology
• Pathophysiology
• Molecular Medicine

Background:

• Coronary microvascular dysfunction (CMD) is a critical factor in acute cardiac events and chronic conditions.
• CMD is implicated in coronary no-reflow post-percutaneous coronary interventions and diastolic dysfunction in heart failure with preserved ejection fraction (HFpEF).
• Chronic low-grade inflammation is increasingly recognized as a contributor to cardiovascular complications, potentially linking HFpEF mechanisms.

Purpose of the Study:

• To review the current evidence on the role of CMD in the development of HFpEF.
• To focus on the molecular mediators of chronic inflammation and oxidative stress involved in CMD and HFpEF.
• To discuss potential therapeutic strategies for the treatment and prevention of CMD-related HFpEF.

Main Methods:

• Literature review of recent studies.
• Analysis of molecular mechanisms linking inflammation, oxidative stress, and CMD.
• Synthesis of evidence regarding the hyaluronan-CD44 axis in cardiovascular pathologies.

Main Results:

• CMD is a significant contributor to HFpEF pathophysiology.
• Pro-inflammatory mediators and oxidative stress are key molecular players in CMD-related HFpEF.
• The hyaluronan-CD44 axis presents a potential area for further research and therapeutic intervention.

Conclusions:

• CMD plays a crucial role in the development of HFpEF.
• Targeting inflammatory and oxidative stress pathways, including the hyaluronan-CD44 axis, may offer novel therapeutic avenues for HFpEF.
• Further research is warranted to elucidate these mechanisms and develop effective treatments.
