LEPTIN GENE EXPRESSION IN EPICARDIAL ADIPOSE TISSUE IN MALES WITH CORONARY HEART DISEASE

Objective. Evaluate leptin gene expression in epicardial adipose tissue in males with coronary heart disease (CHD). Design and methods. We enrolled 106 males: 57 males with CHD aged 61,3 ± 1,1 years old and 49 males without CHD aged 57,3 ± 1,3 years old (p > 0,05). Epicardial adipose tissue (EAT) specimens were obtained in 65 males (57 males with CHD and 8 males with valvular heart disease without CHD) undergoing cardiac surgery. Serum leptin was measured by immune enzyme assay (IEA). Leptin mRNA (messenger ribonucleic acid) level in EAT was assessed by real-time polymerase chain reaction. All patients underwent coronaroangiography and echocardiography. Results. Leptin mRNA level in EAT was significantly higher in males with CHD and atherosclerosis of main coronary arteries. Patients with multivessel (3 and more coronary arteries) atherosclerotic lesions showed higher leptin mRNA level in EAT than in subjects with lesions of 1–2 coronary artery and in patients without CHD: 2,84 ± 0,04 (RU), 1,91 ± 0,03 RU and 1,41 ± 0,02 RU, respectively (р < 0,05). Conclusions. Paracrine activity of epicardial adipose tissue plays a role in the pathogenesis of coronary atherosclerotic lesions in males
