title: Relation of body fat distribution in men and degree of coronary narrowings in coronary artery disease.
abstract: This study evaluates the relation between body fat distribution and severity of coronary artery disease (CAD). The study sample comprised 33 patients with angiographically demonstrated CAD and 10 angiographically normal control subjects. Body fat distribution was estimated by computed tomography and degree of coronary narrowings by angiographic score. Body weight, body mass index and total and subcutaneous abdominal adipose tissue areas showed no statistical differences in the 2 groups; visceral abdominal adipose tissue area and the visceral to subcutaneous abdominal adipose tissue area ratio were significantly higher in patients with CAD (p < 0.05). There was a significant correlation between visceral fat and triglycerides, apoprotein B and sum of glucose and insulin during glucose oral tolerance test. Sum of insulin during glucose oral tolerance test, visceral abdominal adipose tissue area and visceral/subcutaneous abdominal adipose tissue area ratio correlated significantly with severity of CAD, as evaluated by coronary score in all subjects and in CAD patients alone. Stepwise multiple regression analysis using the coronary score as the dependent variable and anthropometric and metabolic parameters as independent variables shows that in all subjects and in CAD patients alone, visceral/subcutaneous abdominal adipose-tissue area ratio entered the regression first and the sum of insulin during glucose oral tolerance test second. The results suggest that visceral abdominal adipose tissue area and visceral to subcutaneous abdominal adipose tissue area ratio may be cardiovascular risk factors.
