Aim. During one-year follow-up, to assess the effect of genetic and nongenetic factors on the risk of poor outcomes in patients after myocardial infarction (MI) with high medical adherence.Material and methods. The study included 250 patients admitted to the hospital due to MI in the period from September 1, 2018 to May 1, 2019 and with a potentially high medical adherence. Twelve months after MI, patients were assessed for adherence to therapy and the effect of genetic and nongenetic factors on the patient prognosis.Results. Within 12 months after MI, 70 (28,0%) patients had a composite endpoint: all-cause death, MI, cerebral stroke, and nonelective coronary revascularization. There were following factors increasing the risk of composite endpoint: non-Q-wave MI (relative risk (RR), 2,63; 95% confidence interval (CI): 1,63-4,25 (p=0,001); left ventricular ejection fraction ≤35% — RR, 2,03; 95% CI: 1,17-3,50 (p<0,0001); CYP2C19 GA/AA genotype (RR, 1,58; 95% CI: 1,06-2,37 (p<0,00001)).Conclusion. The study results allow identifying patients with a high risk of poor outcome: patients with non-Q-wave MI, left ventricular ejection fraction ≤35%, and CYP2C19 GA/AA genotype.

Purpose of the study. Analyze the parameters of the interaction between the left ventricle and the arterial system in patients with chronic forms of coronary heart disease and to identify relationships with levels of proadrenomedullin (MR‑proADM) and N‑terminal precursor of the brain natriuretic peptide B (NT‑proBNP).Materials and methods.240 patients with chronic forms of coronary heart disease (median – 55,9 [43; 63] years) and Q‑forming myocardial infarction in the past were examined. Of these, 110 patients with myocardial infarction and preserved lef ventricular ejection fraction and 130 patients with ischemic cardiomyopathy. All patients were calculated parameters of lef ventricular‑arterial interaction and the determination in blood serum levels of MR‑proADM and NT‑proBNP.Results.In patients with ischemic cardiomyopathy, an increase in the lef ventricular‑arterial interaction index was detected (2,51 [1,18; 5,00]), which reflects a decrease in the functional abilities and efficiency of the heart. In patients with myocardial infarction and a preserved left ventricular ejection fraction, this indicator was in the range of normal values (0,78 [0,55; 1,07]), which indicates an effective cardiac work. A study of MR‑proADM and NT‑proBNP levels demonstrated an increase in both groups (1,72 [1,56; 1,98] nmol/l and 779,3 [473; 2193] pg/ml in the group of patients with ischemic cardiomyopathy; 0,89 [0,51; 1,35] nmol/l and 246 [118; 430] pg/ml in the group of patients with myocardial infarction and preserved left ventricular ejection fraction), and the correlation analysis with left ventricular‑arterial coupling interaction parameters allowed identify statistically significant connections (in the group of patients with ischemic cardiomyopathy: with the level of MR‑proADM ‑ r=0,67, p=0,006, with the level of NT‑proBNP ‑ r=0,78, p<0,001; in the group of patients with myocardial infarction and preserved left ventricular ejection fraction: with MR‑proADM level ‑ r=‑0,52, p=0,024, with NT‑proBNP level ‑ r =‑0,38, p=0,037).Conclusion.The findings suggest a pathogenetic association between the biomarkers under study and the parameters of left ventricular‑arterial coupling interaction.
