Breakthrough in heart failure with preserved ejection fraction: are we there yet?

Area of Science:

• Cardiology
• Vascular Biology
• Pathophysiology

Background:

• Heart failure with preserved ejection fraction (HFPEF) presents a significant and growing global health challenge.
• The complex and heterogeneous nature of HFPEF has hindered the development of effective therapeutic strategies.
• Emerging evidence highlights systemic inflammation and endothelial dysfunction as key contributors to HFPEF pathophysiology.

Purpose of the Study:

• To review the critical role of the endothelium in maintaining cardiovascular homeostasis.
• To elucidate how disrupted endothelial signaling pathways contribute to the development of HFPEF.
• To summarize novel therapeutic approaches targeting endothelial dysfunction in HFPEF.

Main Methods:

• Literature review focusing on endothelial function in cardiovascular homeostasis.
• Analysis of signaling pathways implicated in HFPEF pathogenesis.
• Survey of current and emerging therapies for HFPEF.

Main Results:

• The endothelium plays a vital role in regulating vascular tone, inflammation, and permeability.
• Dysfunctional endothelial signaling contributes to the structural and functional changes observed in HFPEF.
• Several novel therapeutic targets within endothelial pathways are under investigation.

Conclusions:

• Systemic inflammation and endothelial dysfunction are central to HFPEF.
• Targeting endothelial pathways represents a promising therapeutic avenue for HFPEF.
• Further research is needed to translate these findings into effective clinical treatments.
