Abstract:
Aim: The aim of the study was to evaluate PCI and CABG long-term results in patients with multivessel disease during 8–10 years observation based on the CCS scale, vital status and left ventricular ejection fraction (LVEF). Materials and methods: The analysis involved 100 patients, who were randomized to SOS study (PCI-49; CABG-51) in 1997–2000 in the Silesian Heart Center, Katowice, Poland. There was no difference between both groups according to the basic demographic and angiographic data. The average time of observation was 8,4 ± 0,85 years. Echocardiography was performed four times in each patient: before and after the procedure, 3–4 years later and last time 8–10 years after the procedure. Stenocardia was assessed in accordance with the CCS classification. Results: During nearly 10 years follow-up there was 9 deaths in the PCI group (18%, 4 cardiac -8%) and 8 deaths in the CABG group (16%, 4 cardiac, 8%) (F-Cox-test: p=ns for all cause mortality and cardiac death). LVEF and intensification of stenocardia estimated based on CCS classification were not statistically different between both groups at the end of observation. However, in PCI group LVEF increased significantly (p=0,03), while in CABG group it was unchanged. In both groups improvement of symptoms after revascularization was maintained during the follow-up (Wilcoxon test: p 〈 0.001) but it was achieved with repeat revascularization, which was more frequent in PCI group (30 vs 6%, p=0.003). Conclusions: Long-term results demonstrate that both methods of the myocardial revascularization are equal in terms of long-term survival, release of angina and preservation of left ventricular systolic function.
