Relevance. Currently, the number of percutaneous coronary interventions continues to increase, which leads to an increase in the absolute number of restenosis cases, which is the main complication of the long-term postoperative period. The search for risk factors responsible for restenosis and artery re-narrowing mechanisms in order to prevent this complication is an important goal in interventional cardiology. Risk factors for the restenosis development include clinical, angiographic and genetic factors. An active search for biomolecular markers associated with the coronary artery restenosis is currently underway. Objective: to study the role of polymorphic variants C-174G of the IL6 gene and C-819T of the IL10 gene as a risk factor for the development of restenosis in patients after stent implantation. Materials and Methods : The study included 113 patients with stable coronary artery disease, who had previously undergone balloon angioplasty and implantation of drug-eluting stents, and 62 patients with intact arteries that were included to the control group. Statistical data processing was carried out using the R-language program and the SPSS Statistics 20 software package. Results: GG genotype for IL6 gene was associated with the development of coronary artery disease. In the subgroup of patients over 65 years of age and instent restenosis, the GG genotype was significantly less frequent. The homozygous CC genotype for IL10 gene was associated with rapid angiographic in-stent restenosis progression.
