EARLY AND LONG-TERM CLINICAL OUTCOMES IN PATIENTS WITH UNSTABLE ANGINA AND CORONARY ARTERY STENTING

Aim. To study early and long-term clinical outcomes in patients with unstable angina (UA) and coronary artery stenting based on the results of a seven-year follow-up. Materials and Methods. The study included 165 patients with UA and coronary artery stenting. The average age of patients was 59.04±10.34 years; the number of male patients was 129 (78.2%). The risk by the GRACE scale was 96.9±17.46 points. The average number of affected coronary arteries was 2.23±1.07 per person, the average number of implanted stents was 2.10±1.45 per person, the average length of the stented area was 43.12±25.6 mm. Everolimus- or sirolimus-eluting stents were used. All patients were assessed for troponin I, myeloperoxidase, and C-reactive protein; platelet, plasma, and vascular hemostasis were evaluated. The patients underwent echocardiography, coronary angiography. The follow-up period was 7±1.6 years. Results. During a 7-year follow-up period, with endovascular treatment strategy and double antithrombotic therapy with clopidogrel 75 mg and acetylsalicylic acid 75 mg repeated UA developed in 91 (55.2%) pts and myocardial infarction was registered in 21 (12.7%) pts. Cardiovascular mortality was 7.3%
