Inflammatory Mechanisms in Heart Failure with Preserved Ejection Fraction

Area of Science:

• Cardiology
• Immunology
• Pathophysiology

Background:

• Heart failure with preserved ejection fraction (HFpEF) is the predominant form of heart failure.
• Limited therapeutic options are available for HFpEF patients.
• Comorbidity burden is increasingly recognized as a driver of HFpEF.

Purpose of the Study:

• To review the evidence linking comorbidity-driven inflammation to HFpEF pathophysiology.
• To elucidate the mechanistic role of inflammation in myocardial remodeling in HFpEF.

Main Methods:

• Literature review of studies investigating inflammation in HFpEF.
• Analysis of mechanistic pathways connecting comorbidities, inflammation, and cardiac remodeling.

Main Results:

• Comorbidity burden triggers systemic and myocardial inflammation in HFpEF.
• Inflammation contributes to pathological myocardial remodeling, a hallmark of HFpEF.

Conclusions:

• Inflammation is a critical mediator in HFpEF, driven by comorbidities.
• Targeting inflammation represents a potential therapeutic strategy for HFpEF.
