THE LIPID METABOLISM IN YOUNG AND MEDIUM MEN AGE WITH MYOCARDIAL INFARCTION AND RECURRENT EPISODES OF ISCHEMIA

Relevance. Dyslipidemia is considered one of the main risk factors for the development of recurrent myocardial infarction and early postinfarction angina. Aim. To evaluate the features of lipid metabolism in acute and subacute myocardial infarction in men under 60 years old with recurrent episodes of ischemia (recurrent myocardial infarction and/or early postinfarction angina) to search for new approaches to improve prevention measures. Material and methods. The study included men aged 19-60 years old with type I myocardial infarction. Patients are divided into two age-comparable groups: I - the study group, with recurrent myocardial infarction - 68 patients; II - control, without it - 427 patients. A comparative assessment of lipid metabolism parameters and their dynamics in selected groups were performed. Results. The study group differed in higher levels of total serum cholesterol (6.17±1.78 mmol/l) from the control group (5.56±1.28 mmol/l; p=0.02) at the end of the third week of disease, its dynamics during the observation period (I: 9.1%; p<0.0001; II: -1.8%; p<0.0001) and the dynamics of the atherogenic coefficient (I: -4.7.1; p=0.02; II: 6.3%; p<0.0001). In both groups, the group showed an increase in lipoproteins of low (I: 33.1; p=0.02; II: 45.5%; p<0.0001) and very low density (I: 275.8; p=0,0004; II: 233.4%; p<0.0001), atherogenic indices, decrease: triglycerides (I: -31.8%; p=0.02; II: -1.7%; p<0.0001) and high-density lipoproteins (I: -0.6%; p=0.02; II: -6.1%; p<0.0001). Conclusions. The group with recurrent ischemia is characterized by more pronounced hypercholesterolemia at the end of the subacute period of myocardial infarction in comparison with the control group due to an increase in the concentrations of atherogenic lipid metabolism fractions. The dynamics of indices and the coefficient of atherogenicity during this period is multidirectional, which requires additional study.
