Lipid profile parameters in men with coronary heart disease in different age categories in connection with sex hormone level

Abstract

Aim of the study was to investigate the main components of the lipid spectrum of blood serum in patients with coronary artery disease, depending on the level of estradiol (E2), testosterone (T) and age.Material and methods. We examined 161 men aged 35–65 years (median [lower quartile; upper quartile] 53.1 [40.1; 59.4] years) with a history of myocardial infarction more than 30 days before inclusion in the study. Patients were divided into groups by age (35–55 and 56–65 years), as well as according to the content of sex hormones: T ≥ 12 nmol/l and T < 12 nmol/l, E2 ≥ 0.194 nmol/l and E2 < 0.194 nmol/l with double determination.Results. Of the studied components of the lipid profile, the greatest number of significant changes in men with coronary artery disease in different groups, depending on age and levels of sex steroids, had triglyceride (TG) level. In men aged 35–55 and 56–65 years with hypogonadism, TG concentration was higher compared to peers with normal androgen levels. In the older age group, relatively younger male patients, both when comparing a cohort of men with low T and with its normal values, TG content was also higher. In groups of patients with T level > 12 nmol/l and ≤ 12 nmol, when controlling for height and body weight, there is a statistically significant direct association of age in men of 56–65 years with TG concentration (r = 0.483, p = 0.023 and r = 0.549, p = 0.008, respectively). It was found that in patients with coronary artery disease in the age groups of 35–55 years and 56–65 years with E2 content ≥ 0.194 nmol/l, the TG level was higher than in men with normal estrogen concentration (p = 0.008 and p = 0.033, respectively). In a partial correlation analysis with control of height and body weight in men aged 35–55 years with coronary artery disease, a statistically significant relationship was found between the level of E2 ≥ 0.194 nmol/l and TG content (r = 0.566, p = 0.009), a similar relationship independent of anthropometric parameters was verified and in the older age group (r = 0.316, p = 0.011). In a multivariate analysis, the level of TG was determined by E2 concentration, the other variables under consideration did not statistically significantly affect it.Conclusions. Hypogonadism in men in each age group studied is associated with elevated TG content. A significant role in the development of hypertriglyceridemia in men is played by hyperestrogenemia in both age groups, being an independent, independent of androgenic status, proatherogenic factor.
