Gender characteristics of lipid profile parameters and markers of vascular inflammation in patients with stable angina pectoris ingroups with presence and absence of type 2 diabetes

The study of the parameters of the lipid profile and markers of the inflammatory reaction of the vascular wall in patients with stable angina pectoris in the presence or absence of type 2 diabetes mellitus (T2DM) is of great importance for revealing the gender characteristics of the pathophysiological mechanisms of the development and course of diseases, developing secondary prevention of complications and determining the prognosis. 194 patients with stable angina pectoris (SA), single-vessel coronary artery disease, mean age 60.3 ± 7.8 years were examined. Patients were divided into two groups: group 1 - patients with SA without diabetes 2 (n = 152), group 2 - with SA and diabetes 2 (n = 42). In each group, subgroups of men and women are distinguished. The study of biomarkers was carried out upon admission to the hospital on the background of therapy, taken on an outpatient basis. The study included a complex of parameters of the lipid spectrum, markers of the inflammatory response, endothelial dysfunction, and carbohydrate metabolism parameters. A comparative analysis of biomarkers revealed an excess of reference values of atherogenic lipid fractions in both groups of patients, regardless of patient gender. Moreover, in the first group of patients, in the subgroup of women, a significant excess of the level of TC, PL (a), and ApoA-1 was registered compared with the subgroup of men. In the second group, there were no significant differences in parameters between the male and female subgroups. Evaluation of the parameters of the inflammatory reaction revealed in the subgroup of women with T2DM a steady tendency to exceed the level of hs-CRP, TNF-α, homocysteine compared with both men and women in the SA group without T2DM. The logistic regression revealed the main biochemical markers that affect the aggravation of the course of IHD in women with T2DM: this is a uric acid level of more than 380 mmol / l - OS 11.5 (95% CI 1.71-77.69), TNF-α more 8 pg / ml - OR 7.5 (95% CI 1.07-52.46) and an increase in TG - OR 3.33 (95% CI 1.073-10.335). Thus, women of the 2nd group with the presence of T2DM are characterized by the highest level of atherogenic fractions of lipids, markers of vascular inflammation, glucose and HbA1c, which may indicate the greatest potential for the development of atherothrombotic complications in this subgroup of patients.
