BACKGROUND: Metabolic disturbances are common features of polycystic ovary syndrome (PCOS), which possibly enhance the risk of cardiovascular disease. The aim of this study was to assess the accuracy of lipid accumulation product (LAP) index as a marker of cardiovascular risk in PCOS patients. METHODS: Case–control study including 51 PCOS patients aged between 14 and 35 years and 44 body mass index (BMI) and age-matched controls. Measures included the LAP index, homeostasis model assessment (HOMA) index, glucose tolerance and plasma hormones, cholesterols and triglycerides. RESULTS: LAP index was positively correlated with HOMA index in all subjects (r = 0.70; P < 0.001). Waist circumference (WC) (P = 0.002), HOMA index (P < 0.001) and LAP index (P = 0.035) were higher in PCOS patients than controls. On receiver operating characteristic curve analysis, an LAP index of 34.5 (sensitivity: 84%; specificity 79%) showed a better performance than non-high-density lipoprotein cholesterol, WC or BMI to identify insulin resistance (IR) in all subjects. In PCOS patients, the positive and negative predictive values for LAP 34.5 were 91 and 74%, respectively, compared with 73 and 61%, respectively, for WC 80 cm, and 43 and 20%, respectively, for WC 88 cm. CONCLUSIONS: We have confirmed that IR is more common in PCOS than BMI-matched control women. Furthermore, the LAP index, an easily obtainable measure, is associated with HOMA index and an LAP 34.5 is an additional risk factor for cardiovascular disease in PCOS patients.
