Background: Traditional strategies for primary cardiovascular prevention have been insufficient in reducing the high rates of coronary ischemic events in women, probably because these women are often stratified into low-risk groups. However, cardiovascular diseases continue to be the main cause of morbidity and mortality in women worldwide. We hypothesized that carotid atherosclerosis (CA) is common in middle-aged women. Methods: We prospectively evaluated asymptomatic peri- and post-menopausal women with no cardiovascular diseases or the use of hormone therapy from two gynecologic clinics. All the patients underwent full clinical and laboratory evaluation and underwent a B-mode ultrasound for carotid evaluations. The presence of CA was defined as the presence of plaque and/or carotid intima-media thickness (CIMT)>1.00 mm. We performed logistic regression to evaluate independent predictors of CA. Results: We studied 823 women (age: 54.4±5.4 years; body mass index-BMI: 28.5±4.9 kg/m2; diabetes:10%; hypertension: 58%). The prevalence of CA was 12.7% for the entire population and 11% for the low-risk sub-group as defined by a Framingham risk score <5%. In the multivariate model, age: odds ratio (OR) = 1.54, 95% confidence interval (CI) = 1.25–1.89,p<0.001; current smoker status: OR = 2.69, 95% CI = 1.48–4.91, p = 0.001; total cholesterol: OR = 1.13, 95% CI = 1.03–1.24, p = 0.008; and systolic blood pressure: OR = 1.01, 95% CI = 1.00–1.02, p = 0.030 remained independently associated with CA. Conclusion: Subclinical CA is common among asymptomatic middle-aged women, and traditional risk factors are independently associated with CA. These findings are particularly relevant for improving cardiovascular health in women. [ABSTRACT FROM AUTHOR]

WAIST circumference , *MENOPAUSE , *ATHEROSCLEROSIS , *SEX hormones , *INSULIN resistance - Abstract
Background: The high-sensitivity C-reactive protein (hs-CRP) seems to be associated with the presence of atherosclerosis. The association between menopause-related changes in endogenous sex hormones and hs-CRP levels remains controversial. Objective: To compare the levels of hs-CRP in pre- and postmenopausal women and to evaluate the association of endogenous sex hormones, waist circumference (WC) and insulin resistance with the levels of hs-CRP. Methods: This cross-sectional study included 145 women (age range: 45-65 years), 56 premenopausal and 89 postmenopausal. Patients were evaluated for hormonal and lipid profile, HOMA-IR, hs-CRP and WC. Each variable was first assessed for correlation with log hs-CRP using a univariate model, and significant variables were then added to the multivariate regression model. A p value <0.05 was considered statistically significant. Results: The hs-CRP is higher in postmenopausal patients (3.6 ± 4.9 versus 2.6 ± 3.7, p = 0.004). The log hs-CRP was positively correlated with WC ( r = 0.13, p = 0.005), HOMA-IR ( r = 0.29, p = 0.001), and triglycerides ( r = 0.50, p = 0.01). The menopausal status ( p = 0.02) and WC ( p = 0.00003) behaved as independent predictors of hs-CRP levels. No correlation was found between hs-CRP and the time since menopause ( r = −0.1, p = 0.58). Conclusions: The hs-CRP is higher in postmenopausal patients. The menopausal status and WC were independently associated with hs-CRP levels in this sample of pre and postmenopausal women.

Abstract: Objective: To evaluate the presence of premature subclinical atherosclerosis, measured by examining carotid intima-media thickness (IMT) and to investigate whether the IMT may be linked to low-grade chronic inflammation, assessed by C-reactive protein (CRP), in young women with polycystic ovary syndrome (PCOS). Methods: Fifty seven PCOS patients and 37 similarly aged and weight controls underwent B-mode ultrasonography of the carotid arteries for IMT measure. All these women were also screened for CRP and metabolic parameters including fasting insulin, glucose, lipid and androgen levels. Differences between means were analyzed by Student''s unpaired t-test and analysis of correlations between parameters was performed by using Pearson''s correlation. Results: CRP was significantly higher in PCOS patients than in controls (3.1mg/dL vs. 1.4mg/dL; p =0.004). No difference was noted in IMT mean between PCOS cases and controls (0.52mm vs. 0.53mm; p =0.35). IMT did not correlate with CRP but exhibited a significant positive correlation with total testosterone (r =0.72, p =0.01). Conclusion: This study suggests that PCOS itself is not associated with structural arterial injury, carotid IMT is not linked to low-grade chronic inflammation and hyperandrogenism may be associated with subclinical atherosclerosis and cardiovascular risk in young women with PCOS. Additional research is needed to clarify these findings. [Copyright &y& Elsevier]
