Aim. To identify genetic markers of risk for ST-elevated myocardial infarction (STEMI).Material and methods. The study included 210 patients (119 men, 91 women) with STEMI, hospitalized from December 21, 2016 to June 16, 2017 The average age of men was 55,5±9,5 years, women — 57,5±9,1 years. The diagnosis of STEMI was verified according to the criteria of the European Society of Cardiology (2015, 2017). During hospitalization, patients underwent clinical and instrumental examination, stipulated by medical care standards and clinical guidelines We also conducted a genetic study of single nucleotide polymorphisms (SNPs), which showed their association with the risk of coronary artery disease (CAD) and acute myocardial infarction (AMI) according to the GWAS: rs2820315 of the LMOD1 gene (Leiomodin 1, mapped on chromosome 1), rs9349379 of the PHACTR1 gene (regulator 1 of actin and phosphotase, localized on chromosome 6p241), rs867186 of the PROCR gene (Protein C receptor, located on chromosome 20q11.22), rsi1799883 of the FABP2 gene (Fatty acid-binding protein 2, located on chromosome 4q26). Statistical data analysis was performed using the SPSS 170.5 software package and authorial odds ratio (OR) calculator.Results. Carriage of the CC genotype of rs2820315 polymorphism of the LMOD gene is associated with an increased risk of STEMI by 1,87 times (95% CI 1,2862,722, p=0,016). Carriers of the CT genotype of rs2820315 polymorphism have a reduced risk of STEMI (OR 0,633; 95% CI 0,436-0,918, p=0,016).Conclusion. In order to identify risk groups for STEMI development, the study of the rs2820315 polymorphism of the LMOD gene is recommended. This will define the high-risk group for STEMI for developing of personalized programs for primary and secondary prevention of cardiovascular events in practical health care, which will contribute to reducing of STEMI mortality.
