BACKGROUND: Cardiovascular disease remains a major public health problem associated with high mortality. The development of these diseases is associated with many genetic and cardiovascular risk factors, so the study of a person’s genetic predisposition to the development of cardiovascular disease based on gene polymorphism remains actual. The aim of research was to study the combination of polymorphisms of the ADRB1 rs1801253, AGT rs4762, SOD2 rs4880 and CAT rs1001179 genes in healthy young people to assess individual genetic predisposition to the development of cardiovascular disease. MATERIALS AND METHODS: The study involved 33 people aged 19 to 21 years who currently had no pathology of the cardiovascular system. DNA was isolated from oral epithelial cells. Genotyping of DNA samples was determined using real-time polymerase chain reaction. RESULTS: Among those examined, 39.4% had one or two unfavorable alleles for the ADRB1, AGT genes, suggesting a genetic predisposition to the development of cardiovascular disease. Unfavorable alleles of the ADRB1 gene were more common compared to the AGT gene. Each of those examined at risk of developing cardiovascular disease had one or two alleles associated with a decrease in the functioning of enzymes of the antioxidant system. Of the 33 people, only four (12.1%) do not have an unfavorable allele for the SOD2 and CAT genes. CONCLUSIONS: We believe that the determination of polymorphisms in genes for enzymes of the antioxidant system will be an important additional criterion for earlier and more active prevention of cardiovascular disease.
