Association between omentin and echo parameters in patients with chronic heart failure

Area of Science:

• Cardiology
• Endocrinology
• Biomedical Research

Background:

• Adipokines from adipose tissue are linked to heart disease via inflammation and apoptosis.
• Omentin is identified as a novel adipokine.
• Investigating omentin's role in chronic heart failure (CHF) is crucial.

Purpose of the Study:

• To examine the relationship between circulating omentin levels and cardiac dysfunction in patients with CHF.
• To determine if omentin can serve as a biomarker for cardiac dysfunction in CHF.

Main Methods:

• Studied 189 CHF patients, measuring serum omentin and echocardiographic parameters.
• Divided patients into two groups based on left ventricular ejection fraction (EF): EF ≥40% (EF-H) and EF <40% (EF-L).
• Utilized linear regression and multiple logistic regression analyses to assess correlations and associations.

Main Results:

• The EF-L group had significantly higher omentin levels than the EF-H group (P<0.001).
• Serum omentin positively correlated with left atrial diameter, left ventricular end-systolic, and end-diastolic dimensions.
• Serum omentin negatively correlated with left ventricular ejection fraction (r=-0.45, P=0.001).
• High omentin levels were associated with cardiac dysfunction in CHF patients (OR=1.22, P=0.009).

Conclusions:

• Elevated serum omentin shows a mild relationship with cardiac volume and function changes in CHF patients.
• The clinical utility of omentin in CHF requires further investigation.
• Omentin's precise role in the pathophysiology of heart failure needs clarification.
