Subcutaneous and Epicardial Adipose Tissue Leptin Gene Expression in Coronary Artery Disease Patient

Objective. To assess the expression of the leptin gene (LEP) in the epicardial (EAT) and subcutaneous (SAT) adipose tissue in coronary artery disease (CAD) patients.Methods. 107 people were examined: 87 with CAD (57 men, 30 women), 20 without CAD (10 men, 10 women). Biopsy of EAT, SAT, coronary angiography, heart computed tomography, blood leptin levels were estimate, mRNA expression of the LEP gene evaluated by PCR.Results. In CAD patients with multivessel coronary artery lesion, the level of blood leptin is the highest. The expression of the LEP gene in EAT is higher in men than in women, in men with CAD higher than in non-coronary artery disease patients, and with a multivascular coronary lesion higher than in a 1–2 vascular lesion. Expression of the LEP gene in EAT in women with CAD is higher than with no CAD, and does not depend on the severity of coronary atherosclerosis. In SAT, LEP gene expression in men with CAD is higher than without CAD; women with CAD are lower than without CAD. Expression of the LEP gene in SAT is higher in men with a multivascular lesion than in 1–2 vascular lesion, and lower in women with a multivascular damage.Conclusions. The expression of the leptin gene in women is higher in SAT, and in men in EAT. Expression of the leptin gene in EAT with CAD is higher than without CAD. The expression of the leptin gene in SAT in men with CAD, especially with multivessel lesions, is higher than without coronary artery disease.
