Effects of atorvastatin on vascular function, inflammation, and androgens in women with polycystic ovary syndrome: a double-blind, randomized, placebo-controlled trial

To determine the effects of statins on vascular function, inflammation, and androgen levels in women with polycystic ovary syndrome (PCOS), we randomized 20 women with PCOS who had low-density lipoprotein cholesterol levels >100 mg/dL to atorvastatin (40 mg/day) or placebo for 6 weeks and found that atorvastatin reduced androgen levels, biomarkers of inflammation, and blood pressure; increased insulin levels and brachial artery conductance during reactive hyperemia; and failed to improve brachial artery flow–mediated dilation. We conclude that until additional studies demonstrate a clear risk-to-benefit ratio favoring statin therapy in PCOS, statins should only be used in women with PCOS who meet current indications for statin treatment.
