Objective. to develop independent predictors for predicting long-term myocardial infarction (MI) in patients (pts) with unstable angina (UA) after coronary artery stenting (PCI) based on the results of a seven-year follow-up. Materials and Methods. The study involved 165 pts with UA and coronary artery stenting (PCI). PCI was performed in 3.2±1.6 days after admission to the in-patient department. Drug-coated stents (Xience V and Biomatrix) were used, the average number of stents was 2.1±0.8 per person, the average length of the stented area was 43.12±25.6 mm, and the average diameter of the implanted stents was 3.12±0.5 mm. All patients were assessed for troponin I, myeloperoxidase, and C-reactive protein levels; coagulation hemostasis was assessed; and a thrombin generation test was performed. The aggregatogram was performed on the analyzer Multiplate (ASPI-test, ADP-test). The patients underwent echocardiography, coronary angiography. Double antithrombotic therapy with clopidogrel 75 mg and acetylsalicylic acid 75 mg was prescribed for 12 months. The follow-up period was 7±1.6 years. Results. Repeated UA developed in 91 (55.2%) pts during a 7-year follow-up period, myocardial in
