Cardiovascular disease, while rare in women of reproductive age, is the main cause of mortality in menopause. The purpose of our study was to determine the association of natural menopause with cardiovascular risk factors, including their clustering into metabolic syndrome (MS). A random 5 % representative population sample of women aged 45-54 years was examined. In 575 women, we were able to determine their natural reproductive aging status. Multiple regression analysis was used to calculate the association between age, menopausal status, and risk factors under study. After adjustment for age, there was an increase in the odds ratio of developing MS, as defined by NCEP (OR=2.0; 95 % CI [1.1; 3.7]), and an increase in plasma lipid ratios (total cholesterol/HDL-C, LDL-C/HDL-C, apolipoprotein-B/ apolipoprotein-A1; p<0.05 for all) in postmenopausal women. Age, but not menopausal status, was associated with some single components of MS; only waist circumference significantly increased after menopause, independently of age. Clustering of risk factors in MS and lipid ratios (combined factors) was strongly associated with menopause whereas worsening of single components of MS was strongly associated with age. In conclusion, based on our results, the menopause may pose a risk to women through clustering of cardiovascular risk factors beyond simple aging., M. Lejsková ...

Over the last decade, C-reactive protein concentration analyzed by the high sensitivity method (hsCRP) has been proven as a marker of premature atherosclerosis. Concentration exceeding 2 mg/l represents an increased individual risk of myocardial infarction and stroke but strict application of this borderline is complicated by relations of CRP concentrations to other risk factors of cardiovascular diseases. In a large 1 % representative sample of the Czech population, a positive relation of hsCRP to BMI, a waist circumference and triglyceride concentration was documented. Substantial sex differences were found in its relationship to age. Whereas it is continuously increasing in men, this increase appears in women only after menopause. A substantial decrease of body weight and visceral fat volume by increased physical activity is accompanied by significant decrease of hsCRP in young obese women. This decrease was not related to a change of interleukin-6 concentration, although it is supposed to regulate CRP production. CRP concentration is partly under genetic control as a higher concentration in young siblings of probands with proved coronary atherosclerosis was documented. The participation of genes related to lipoprotein metabolism (genes for apolipoprotein CI and apolipoprotein E) influence hsCRP concentrations. We hypothesized that an increased concentration of hsCRP represents a certain marker of proinflammatory status related to central obesity and triglyceride metabolism and it might be related to individual properties of monocytes in atherogenesis., R.
