Blood hypertension in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is associated with multiple cardiovascular risk factors. The aims of this study are to investigate the prevalence of hypertension in a female population with PCOS and to correlate hypertension with her clinical and hormonal profile. Materials and methods: it is a transversal study of 79 PCOS patients with mean age of 25±7 years (range 13-44). PCOS diagnosis is made by Rotterdam consensus criteria's (2003). WHO definition of hypertension is used (BP 140/90 mmHg). Blood pressure is measured three times in each patient. Ovarian echography and biochemical assays (GnRH test, androgens, cholesterol, triglycerides, and oral glucose tolerance test) are made before the 5th day of the menstrual cycle. Results: 12% of PCOS women have hypertension. Family history of hypertension is not a predictive factor of hypertension in our study. PCOS patients with hypertension are not significantly older than those without hypertension (28.4±6.5 vs 25.2±7; p=0.12). If compared to PCOS women without hypertension, those with hypertension have a significantly higher BMI (39.2±7 vs 29.6; p=0.0004). PCOS patients with and without hypertension do not differ significantly in their level of androgens and total cholesterol. Triglycerides level is higher in PCOS patients with hypertension (p=0.0.06). In oral glucose tolerance test, areas under the curve of insulin and glucose are significantly higher in PCOS patients with hypertension (respectively p=0.06 and 0.02). The area under the curve of LH during GnRH test is lower in PCOS patients with hypertension (p=0.04). Conclusion: hypertension in PCOS is a marker of metabolic syndrome frequently associated with PCOS.
