PURPOSE: To evaluate parameters related with arterial pressure and metabolic profile in women with polycystic ovary syndrome (POS). METHODS: This monocentric study at the University Hospital Endocrinology Section included 60 women aged 18-45 years, 42 being diagnosed with POS and acting as 18 controls. All women were subjected to transvaginal ultrasound and monitored for arterial pressure for 24 h in the ambulatory (MAP). Venous blood samples were taken between 07.00 and 09.00, after 12 h fasting. Basal (BG) and fasting glucose concentrations, total cholesterol and its fractions, triglycerides and insulin (to calculate the homeostatic assay insulin-resistance, HOMA-IR) were measured. Collected data were the mean arterial blood pressure (24-h awake/sleep cycle), arterial pressure nocturnal descensus, glycemia and fasting glucose for HOMA-IR, and lipid profile. The Student's t test was used to compare homogeneous variables; the Mann-Whitney test was used to compare non-homogeneous variables; the Pearson's correlation coefficient was used to search for correlation between the variables. The c² test was used for comparison of the absence of nocturnal descensus. Significance was taken as p<0.05. RESULTS: The mean age of the patients with POS was 27.4±5.5 (18-45 years, n=42) and the body mass index (BMI) was 30.2±6.5 kg/m² (18.3-54.9). In the Control Group, the mean age was 31.4±6.1 (18-45 years) and the BMI was 27.1±6.2 kg/m² (18.3-54.9, n=18). No difference in the metabolic parameters and insulin resistance was observed between the two groups. Comparison between these parameters and MAP showed that the only parameter with a correlation was the BMI, independent of the POS diagnosis. This was not seen in nocturnal descensus, which was uncorrelated with POS and any of the other studied parameters. CONCLUSION: POS women do not show higher arterial blood pressure, glycemia, HDL-col, TG, HOMA-IR and BMI compared to non-POS women. However, POS patients showed correlation between arterial pressure and BMI, suggesting that obesity is a primary factor involved in arterial pressure changes in these patients.

PURPOSE: to investigate the prevalence of elevated blood pressure (BP) in patients with polycystic ovary syndrome (PCOS) and to correlate the BP levels with other cardiovascular risk factors. METHODS: a cross-sectional study was conducted on 113 PCOS women (26.2±4.3 years) and on a Control Group of 242 healthy women from the general population (26.8±5.0 years). The variables considered were: systolic and diastolic BP, anthropometric parameters and plasma levels of glucose, total cholesterol, HDL-cholesterol, and triglycerides. The BP values were classified according to the V Brazilian Guidelines of Hypertension. Statistical analysis was performed by intergroup comparison with the Student's t-test and χ2 test, and correlation analysis was performed using Pearson's coefficient. RESULTS: the PCOS Group showed a significantly higher prevalence of altered BP (>130/85 mmHg) than the Control Group (18.6 versus 9.9%, respectively; p<0.05). PCOS women had higher mean systolic BP, body mass index (BMI), waist circumference (WC), triglycerides and fasting glucose, and lower HDL-cholesterol, compared to the Control Group (p<0.01). In the PCOS Group, the values of systolic and diastolic BP showed a significant positive correlation with age, BMI, WC, and triglycerides (p<0.05). CONCLUSIONS: according to the results obtained, it is possible to conclude that the frequency of women with BP values above the normal limit was significantly higher in the PCOS Group than in the Control Group. Additionally, the BP values also correlated with other cardiovascular risk factors. These findings underscore the importance of preventive strategies in PCOS women, in order to prevent pathological events related to the cardiovascular system.
