"This review systematically addresses the evidence confirming polycystic ovary syndrome (PCOS) as a cardiovascular health threat. Literature in this area is void of long-term prospective studies to adequately evaluate outcome, but there is important evidence using surrogate markers for future development of and presence of cardiovascular disease and diabetes in women with PCOS. In addition, this article reviews the evidence regarding evaluation and management of cardiovascular risk factors in the population of women with PCOS." "Although previously identified as a cause of abnormal uterine bleeding, the term polycystic ovary syndrome (PCOS) was coined in 1935 after Stein and Leventhal reported 7 women who had amenorrhea, hirsutism, obesity, and multicystic appearing ovaries. Since then, a great deal of investigation has gone into why these women have problems of irregular menses, infertility, and hirsutism."

• "Women with PCOS develop diabetes at higher rates and at younger ages than usual. The metabolic syndrome is very prevalent in women with PCOS" "Diabetes does develop earlier and more frequently in women with PCOS."despite this, unlike diabetics-"Some researchers have noted no higher morbidity or mortality rates from circulatory diseases in women with PCOS." "Because of both the high prevalence of type 2 diabetes and impaired glucose tolerance in women with PCOS, we recommend screening all PCOS women using a fasting and 2-hour oral (75 g) glucose tolerance level."
• "Central obesity associated with PCOS is possibly the single most important risk factor for the development of diabetes and cardiovascular disease."
• "Exercise is of obvious benefit in weight reduction and cardiovascular health. In a small (n=21) longitudinal study comparing homocysteine levels in exercising versus nonexercising women with PCOS, Randeva et al found a significant decline in homocysteine levels at 6 months. Patients who complied with a brisk walking regimen showed declines in homocysteine (10.06±3.22 to 7.36±1.96, P<0.001). Homocysteine levels still remained above normal compared to reference range, however. There was also a significant decrease in waist-to-hip ratio, but no decrease in BMI."
• "The use of oral contraceptives in women with PCOS is widespread, and remains a mainstay in the treatment for hirsutism and to protect the endometrium in patients who are oligoovulatory. Given studies in non-PCOS patients which have shown that oral-contraceptive use can confer a higher risk of myocardial infarction, some have questioned the possible deleterious effects of oral contraceptives on the cardiovascular health of patients with PCOS. Several small studies of oral contraceptive use in women with PCOS show worsening of insulin sensitivity, worsening of glucose tolerance in obese patients (but not in nonobese patients)"
• "The goal is to keep the blood pressure <120/80 through lifestyle approaches. Pharmacotherapy is indicated when blood pressure is >140/90. Pharmacotherapy should be initiated at even lower blood pressure cutoff levels in the setting of target organ damage or diabetes. Thiazide diuretics should be part of the regimen for most patients, unless contraindicated. Angiotensin converting enzyme inhibitors or angiotensin receptor blocker are the drugs of choice for those with the metabolic syndrome and hypertension. These should not be used if pregnancy is contemplated."

• "Approximately one-third to one-half of all women and adolescent girls with polycystic ovary syndrome (PCOS) has the metabolic syndrome, associated with increased risk for cardiovascular disease and type 2 diabetes. Evidence suggests that insulin resistance is the likely link between PCOS and the metabolic syndrome."

"More recently, researchers compared stress responses among women with PCOS with those of women in 2 other groups: women with functional hypothalamic secondary amenorrhea (FHSA), or psychogenic amenorrhea, and a control group of normally menstruating women (40). The investigators introduced a cognitive stressor, the Stroop Color Word test, and judged its impact by assessing both cognitive performance and physiological indices in participants. Although women with PCOS did not differ from control group women in cognitive response, the stressor did cause a rise in cortisol levels among women with PCOS that was not observed in control group women. However, the FHSA group was most affected by the stressor, significantly differing from the PCOS and control groups on both types of measures. Consequently, evidence for heightened susceptibility to stress among women with PCOS is at best slight."

"Physicians' impressions about hirsutism range from considering it simply a cosmetic problem to assuming it is de facto evidence of excess androgen. The truth lies somewhere in between. Although unwanted hair is often due to an ethnic or familial trait, about half the cases of hirsutism are due to hyperandrogenism."
