The purpose of the study was to investigate the effect of reperfusion therapy on the levels of endothelial nitric oxide synthase in patients with acute myocardial infarction and concomitant type 2 diabetes mellitus. Materials and methods. The study involved patients with acute myocardial infarction, who were divided into groups depending on the presence of type 2 diabetes mellitus and the therapy performed for them: group 1 – 58 patients with acute myocardial infarction and diabetes mellitus who underwent percutaneous coronary intervention; group 2 – 15 patients with acute myocardial infarction and diabetes mellitus who underwent exclusively conservative treatment; group 3 – 40 patients with acute myocardial infarction without diabetes who underwent percutaneous coronary intervention; group 4 – 17 patients with acute myocardial infarction without diabetes, who underwent exclusively conservative treatment. Results and discussion. According to the obtained results, in patients with concomitant type 2 diabetes mellitus, significantly lower levels of endothelial nitric oxide synthase were revealed, compared with patients without disturbances in carbohydrate metabolism, which indicates deeper impairments of endothelial function against the background of hyperglycemia and insulin resistance. Analysis of the effect of reperfusion therapy showed a statistically significant increase in the level of endothelial nitric oxide synthase both in the group of patients with concomitant disorders of carbohydrate metabolism and without them, which indicates an improvement in the processes of endothelium-dependent dilation, regardless of the presence or absence of type 2 diabetes mellitus. The obtained results testify to the positive effect of percutaneous coronary intervention at the level of eNOS, which, in our opinion, will help to improve the vasodilating properties of vascular endothelium and prevent a complicated course of acute myocardial infarction. Conclusion. The patients with acute myocardial infarction and concomitant type 2 diabetes mellitus have significantly lower levels of endothelial nitric oxide synthase levels than patients without type 2 diabetes mellitus that indicates deep violations of endothelial function against background of metabolic changes associated with insulin resistance and hyperglycemia. Reperfusion therapy accelerates its restoration regardless of the presence or absence of type 2 diabetes mellitus
