[Revascularization of myocardium: coronary artery bypass grafting or stenting?].
The aim of the study was comparative analysis of long-term results (5 years) after coronary angioplasty and stenting (CAS) and coronary artery bypass grafting (CABG). The results of the treatment of 1100 patients with coronary heart disease, operated since 1999 to 2006 year, were analyzed. 720 (65.5%) patients had undergone CABG (group 1), 226 (20.5%) had had an implantation of stents with pharmaceutical coverage (group 2) 154 (14%) had been implanted with stents without pharmaceutical coverage (group 3). Clinical examination as a rule had occurred before operation, 29-30 days after operation and in every 12 months after discharge from the hospital. Five years survival rate in group of CABG patients was 85.9% and in groups of CAS patients it was 84.1% and 70.8% respectively. Restenosis occurred more frequently in CAS patients: in group 2 in 18.1% patients, in group 3--in 70.1% In group of CABG patients acute myocardial infarction occurred in 11.9% cases to the end of 5th year, in groups 2 and 3 this index was 10.9% and 18.3% respectively. Angina pectoris was absent in 1 year in CABG patients (62%) than in CAS patients (46.7% and 24.3% in groups 2 and 3 respectively; p < 0.05). Comparing results of CAS with use of stents with and without pharmaceutical coverage, the best clinical result was in the group with implanted stents of new generation. Relatively better clinical effect during 5 years occurred in CABG patients.
