Abstract
The aim of this study was to investigate the pattern of body fat distribution and its association with metabolic and hormonal cardiovascular risk factors in women undergoing coronary angiography. Thirty of the 51 women exhibited significant coronary artery disease (CAD) (group A), whereas the remaining 21 subjects were free of major coronary stenoses (group B). Twenty-five healthy women without clinical signs of CAD served as a control group (group C). Despite comparable age and body mass index the women of group A had a significantly higher waist-to-hip ratio (WHR), a measure of the pattern of body fat distribution, than those of group C (0.88 +/- 0.07 vs. 0.78 +/- 0.06, P < 0.01). In an oral glucose tolerance test a high prevalence of impaired glucose tolerance or diabetes was found in groups A and B (53% and 63%, respectively) compared with group C (4%, each P < 0.01). The women of groups A and B showed significantly higher blood pressure and triglyceride levels as well as lower HDL-cholesterol than those of group C, whereas total and LDL-cholesterol were not different between the groups. The serum concentrations of testosterone, sex-hormone-binding globulin (SHBG) and cortisol were comparable between the three groups and correlation analysis revealed positive associations between androgens and WHR (r = 0.36, P < 0.01) and serum insulin (r = 0.34, P < 0.01) respectively. These findings indicate that women with angiographically confirmed CAD, and those with clinical signs of CAD but without significant stenosis, frequently exhibit a metabolic syndrome characterized by a cluster of metabolic abnormalities which may underlie the atherosclerotic process.
