The plasma leptin/adiponectin ratio predicts first cardiovascular event in men: a prospective nested case-control...

Area of Science:

• Endocrinology and Metabolism
• Cardiovascular Disease Research
• Biomarker Discovery

Background:

• The plasma leptin/adiponectin (L/A) ratio is a potential biomarker for atherosclerosis.
• Previous studies suggest the L/A ratio may be superior to individual leptin or adiponectin levels in predicting cardiovascular disease (CVD) risk.

Purpose of the Study:

• To evaluate the predictive value of the L/A ratio for incident CVD in men.
• To compare the predictive power of the L/A ratio against traditional CVD risk factors, microalbuminuria, lipid profiles, hs-CRP, and insulin sensitivity (HOMA(ir)).

Main Methods:

• A prospective nested case-control study involving 103 men with incident CVD and 106 controls.
• Baseline measurements included plasma leptin, adiponectin, L/A ratio, hs-CRP, HOMA(ir), and TC/HDL-C ratio.
• Statistical analysis involved age-adjusted and fully adjusted models to assess CVD prediction.

Main Results:

• Higher plasma leptin levels and L/A ratio were observed in cases compared to controls.
• The L/A ratio remained a significant independent predictor of incident CVD after full adjustment for clinical risk factors (HR: 1.40, p=0.024).
• Individual leptin and adiponectin levels lost their predictive significance after adjustment.

Conclusions:

• The L/A ratio demonstrates potential as a preferential marker for predicting first cardiovascular events in men.
• The L/A ratio offers enhanced predictive value for incident CVD compared to measuring leptin and adiponectin levels independently.
