To evaluate the cardiovascular risk of polycystic ovary syndrome (PCOS), we investigated lipid profile, metabolic pattern, and echocardiography in 30 young women with PCOS and 30 healthy age- and body mass index (BMI)-matched women. PCOS women had higher fasting glucose and insulin levels, homeostasis model assessment score of insulin sensitivity, total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels, and TC/high density lipoprotein cholesterol (HDL-C) ratio and lower HDL-C levels than controls. Additionally, PCOS women had higher left atrium size (32.0 ± 4.9 vs. 27.4 ± 2.1 mm; P <0.0001) and left ventricular mass index (80.5 ± 18.1 vs. 56.1 ± 5.4 g/m2; P <0.0001) and lower left ventricular ejection fraction (64.4 ± 4.1 vs. 67.1 ± 2.6%; P = 0.003) and early to late mitral flow velocity ratio (1.6 ± 0.4 vs. 2.1 ± 0.2; P <0.0001) than controls. When patients and controls were grouped according to BMI [normal weight (BMI, >18 and 2), overweight (BMI, 25.1-30 kg/m2), and obese (BMI, >30 kg/m2)], the differences between PCOS women and controls were maintained in overweight and obese women. In normal weight PCOS women, a significant increase in left ventricular mass indes and a decrease in diastolic filling were observed, notwithstanding no change in TC, LDL-C, HDL-C, TC/HDL-C ratio, and TG compared with controls. In conclusion, our data show the detrimental effect of PCOS on the cardiovascular system even in young women asymptomatic for cardiac disease.
