[Hyperandrogenism as a risk factor of coronary artery disease in young women].

The aim of the study was an attempt to assess the relative roles of common risk factors of coronary artery disease (CAD) and sex hormones in the pathogenesis of CAD in young menstruating women. 38 women in the age of 35-47 years with past myocardial infarction and angiographically proven critical changes in coronary arteries, with one-vessel disease in 22 women (58%) or multi-vessel disease in 16 (42%) were examined. A referee group consisted of 15 healthy women in the age of 35-45 years. In all women multiple risk factors were searched, including value of body mass index (BMI) and waist-hip ratio (WHR). In 4-7 day of sexual cycle at 8.00 a.m. blood from cubital vein was taken to measure concentrations of biochemical parameters and hormones: estradiol, testosterone (T), dehydroepiandrosterone sulphate, folliclestimulating hormone, luteinizing hormone, prolactin, thyreotropin, progesterone, cortisol and sex-hormone binding globulin. In women with CAD, comparing to healthy ones, a higher frequency of arterial hypertension (55% vs 7%), cigarete smoking (95% vs. 46%), hirsutism (84% vs. 30%) and dyslipidaemia was found. Concentration of T was significantly higher in women with CAD than in healthy women (3.5 +/- 1.5 nmol/l--vs. 2.4 +/- 1.0, p < 0.014). In regression analysis was revealed that in multiple parameters a cluster of 2 parameters, dyslipidaemia and hirsutism, was of the best goodness of fit with occurence of CAD. Significant relation with CAD was proven for visceral obesity, eleveted concentration of T and cigarette smoking, either. Conclusions. Apart from common known risk factors as visceral obesity, dyslipidaemia and cigarette smoking it is hiperandrogenism that may participate in pathogenesis of CAD in women in the reproductive age.
