Ilie IR et al. - Polycystic ovary syndrome (PCOS) is possibly the most common endocrinopathy of reproductive age, characterized by hyperandrogenism and oligomenorrhea. Endothelial dysfunction, impaired arterial structure, or proinflammatory markers are early features of atherosclerosis, and can be used as surrogate indicators of future coronary artery disease in women with PCOS. However, as the latest studies show, these symptoms are the result of deleterious effects that cardiovascular risk factors, in particular insulin resistance and obesity, produce on the vascular wall, rather than to the presence of PCOS per se.
