The amount of epicardial adipose tissue (EAT), a component of body visceral adiposity, has been linked to the presence and severity of cardiovascular disease through multiple mechanisms. Polycystic ovary syndrome (PCOS) is characterized by insulin resistance and subclinical inflammation, which participate in the mechanism of atherosclerosis. We searched if the patients with PCOS have increased EAT thickness (EATT), along with its relation to the measures of adiposity and insulin sensitivity. A total of 41 subjects with PCOS and 46 age and body mass index (BMI) matched healthy controls were enrolled. EAT was measured by echocardiography above the free wall of the right ventricle. Insulin resistance was assessed by homeostasis model assessment of insulin resistance (HOMA-IR) formula, and plasma adiponectin level was measured by ELISA. Compared to healthy controls EATT and HOMA-IR score were significantly higher (p=0.0001 for both) while plasma adiponectin concentration was significantly lower (p=0.048) in women with PCOS. EATT correlated positively with total cholesterol, triglyceride, luteinizing hormone (LH) and negatively with sex hormon binding globuline (p<0.05 for all), whereas it displayed no correlation to plasma adiponectin level (p=0.924). Triglyceride level was the significant determinant of EATT in logistic regression analysis (p=0.035). Thickness of the EAT is increased in patients with PCOS in conjunction with hyperandrogenity. Prospective studies are required to identify the relation of EAT and cardiovascular risk in patients with PCOS.
