Introduction. There is an increasing interest in the association between erectile dysfunction (ED) and cardiovascular risk factor. Epicardial adipose tissue (EAT) is associated with insulin resistance, increased cardiometabolic risk, and coronary artery disease. Our aim was to investigate relationships between epicardial fat thickness (EFT) as a cardiometabolic risk factor and erectile dysfunction. Method. We selected 30 erectile dysfunction patients without comorbidities and 30 healthy individuals. IIEF-5 score was applied to all patients, and IIEF-5 score below 22 was considered as erectile dysfunction. EFT was measured by echocardiography. Results. Body mass index (BMI) was higher in ED patients than those without ED (28.19 +/- 4.45 kg/m(2) versus 23.84 +/- 2.36 kg/m(2), P = 0.001, resp.). Waist circumstance (WC) was higher in ED patients than those without ED (106.60 +/- 5.90 versus 87.86 +/- 14.51, P = 0.001, resp.). EFT was higher in ED patients compared to non-ED patients (0.49 +/- 0.09 cm versus 0.45 +/- 0.03 cm, P = 0.016, resp.). There was positive correlation among BMI, WC, and EFT. There was negative correlation between EFT and IIEF-5 score (r : -0.632, P = 0.001). Conclusion. EAT, BMI, and WC as cardiometabolic risk factors were higher in erectile dysfunction patients.
