Some molecular genetic markers of progressive atherosclerosis in patients with coronary heart disease
Abstract
The aim of the study is to evaluate the association of some molecular genetic markers with progressive atherosclerosis. Material and methods. In total, the study included 202 patients (147 men and 55 women), who were divided into 2 groups. The 1st (main) group included patients with coronary artery disease (100 people) who had a combination of two or more cardiovascular events during the last 2 years before inclusion: myocardial infarction or unstable angina pectoris, arterial stenting for urgent indications (coronary and peripheral), stroke; acute ischemia, thrombosis or amputation of the lower extremities. The 2nd group (comparisons) included 102 patients with coronary artery disease who did not have any of the above cardiovascular events during the last 2 years before inclusion. DNA was isolated from peripheral blood samples by phenol-chloroform extraction. Results. According to the frequencies of genotypes of the I/D polymorphism (rs36232792) of the SOD1 gene, no statistically significant differences were obtained between the group with progressive atherosclerosis and the control, neither in general, nor when divided by sex and age. The odds ratio of developing progressive atherosclerosis in carriers of the rare homozygous DD genotype of the rs3834129 polymorphism of the CASP8 gene is 2.3 ne is 2.3 times higher compared to carriers of the other two genotypes (DD vs II + ID, 95 % CI 1.1–5.1; p = 0.037). In men, the odds ratio is higher than in the general group – 4.4, p = 0.015. Women also tend to accumulate carriers of the DD genotype in the group with progressive atherosclerosis (26.7 % vs 16.0 %), but the differences do not reach the level of statistical significance. Conclusions. The carriage of the DD genotype of the rs3834129 polymorphism of the CASP8 gene is associated with progressive atherosclerosis in patients with CAD. No association of I/D polymorphism (rs36232792) of the SOD1 gene with progressive atherosclerosis was found. Acknowledgments. The molecular genetic fragment of the study was supported by State Budget theme no. 122031700094-5.
