ABSTRACT
Polycystic ovary syndrome [PCOS] is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Little is known about cardiovascular risk factors in patients with PCOS. We investigated plasma markers of cardiovascular disease in Saudi women with PCOS, with an emphasis on asymmetric dimethylarginine [ADMA] and total homocysteine [tHcy]. Fifty Saudi women with PCOS diagnosed by the Rotterdam criteria [mean age [SD] 30.2 [3.0] years] and 40 controls without PCOS [mean age 29.3 [2.5] years] had measyrements taken of clinical, metabolic, and hormonal parameters, including plasma ADMA, tHcy, lipoprotein [a] [[Lp[a]], and serum high sensitivity C-reactive protein [hs-CRP], nitric oxid, and fibrinogen. Insulin resistance was calculated by the homeostasis model assessment [HOMA-IR]. Women with PCOS had significantly higher fasting insulin, HOMA-IR, and luteinizing hormone [LH] levels than healthy controls [P<.001]. Lipid profile, free androgen index [FAI], ADMA, tHcy, hsCRP, and Lp[a] were significantly higher in women with PCOS compared with healthy controls [P<.001]. The women with PCOS had significantly lower nitric oxide and high-density lipoprotein cholesterol [HDL-C] levels compared with healthy controls [P<.001]. Our study revealed that Saudi women with PCOS had a significantly different levels of plasma markers of cardiovascular disease compared with normal controls. Therefore, clinicians who manage women with PCOS should follow up on these markers to reduce the risk of cardiovascular disease
