Characterization of Cardiac Sympathetic Nervous System and Inflammatory Activation in HFpEF Patients

Area of Science:

• Cardiology
• Physiology
• Pathophysiology

Background:

• Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome.
• The roles of sympathetic nervous system and inflammation in HFpEF pathophysiology require further elucidation.

Purpose of the Study:

• To investigate the presence and correlation of systemic and cardiac sympathetic activation in HFpEF patients.
• To assess systemic and local myocardial inflammatory activation in HFpEF.
• To explore potential therapeutic targets for HFpEF.

Main Methods:

• Assessment of sympathetic nervous system activity.
• Measurement of systemic and myocardial inflammatory markers.
• Correlation analysis with hemodynamic and demographic factors.

Main Results:

• Systemic and cardiac sympathetic activation were confirmed in HFpEF patients.
• Systemic inflammatory activation was detected, but not local myocardial release of cytokines.
• Sympathetic activation correlated with hemodynamic and demographic factors typical of HFpEF.

Conclusions:

• Data suggest a potential role for antiadrenergic therapies in managing specific HFpEF patient populations.
• Local myocardial cytokines do not appear to be implicated in HFpEF myocardial biology.
• Systemic inflammation may contribute to the overall pathophysiology of HFpEF.
