Cardiovascular Risk in the Different Phenotypes of Polycystic Ovary Syndrome

Cardiovascular Risk in the Different Phenotypes of Polycystic Ovary Syndrome: Background: The polycystic ovary syndrome (PCOS) is the commonest endocrine disorder in women of reproductive age and shows substantial phenotypic variability. According to the presence of the three diagnostic criteria of PCOS, i.e. oligo- and/or anovulation, hyperandrogenemia and/or clinical signs of high androgen levels, and polycystic ovaries, four different phenotypes of PCOS are identified. It appears that these phenotypes differ in the prevalence of several established and emerging cardiovascular risk factors. Methods: We searched the literature for studies that compared the cardiovascular risk profile of patients with the different phenotypes of PCOS. Results: Patients with both anovulation and hyperandrogenemia have more pronounced insulin resistance and higher levels of proinflammatory and prothrombotic mediators than patients with polycystic ovaries and either anovulation or hyperandrogenemia. Conclusion: Given that these differences appear to be mainly driven by the more pronounced obesity of the former patients, diet and exercise aiming at weight loss should constitute the cornerstone of management of PCOS and should be particularly emphasized in patients with the higher risk phenotypes of the syndrome.
