Introduction and aim: Polycystic Ovary Syndrome (PCOS) is a common disorder associated with a wide range of endocrine and metabolic abnormalities. Obesity is present in about 4550% of PCOS women. Increased cardiovascular risk factors and evidence of subclinical cardiovascular disease (CVD) have been reported in PCOS. The aim of the present study was to evaluate whether visceral fat amount may be considered as predictor for early CVD in PCOS women.
Patients and methods: The procedures used were in accordance with the guidelines of the Helsinki Declaration on human experimentation. The study was approved by the local Ethical Committee. Two-hundred PCOS women and 100 healthy age- and body mass index-matched women were enrolled in this prospective baseline-controlled clinical study. Non-invasive markers of early CVD [carotid intima-media thickness (IMT), brachial arterial flow-mediated dilation (FMD)] and visceral fat amount [using abdominal ultrasonography] were evaluated. Inflammatory biomarkers [C-reactive protein (CRP), fibrinogen, white blood cells (WBC) count, plasminogen activated inhibitor (PAI)-1], hormonal and metabolic parameters were also investigated.
Results: Subjects with PCOS had significantly (P<0.001) higher visceral fat compared to healthy women [31.4+7.3 vs. 28.0+6.1, mm+
Conclusions: The early impairment of endothelial structure and function, the increase of low-grade chronic inflammation and insulin resistance in women with PCOS are associated with increased central fat excess. Visceral fat amount could be an important predictor of subclinical CVD in PCOS.
