Abstract
Backgroud: Several studies have compared outcome of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in the treatment of multivessel coronary disease, but a few were focused on patients with reduced left vetricular function. The aim of the study was to compare effectiveness of PCI and CABG in patients with iscaaemic cardiomyopathy and multivessel coronary disease Methods: This single-center study, included 178 patients, admitted because of symptomatic multivessel coronary disease, ejection fraction of left ventricle (EF) ≤50%, who underwent PCI or CABG, with two-years follow up of adverse cardiac and cerebrovascular events (MACCE), which included mortality, myocardial infarction (MI), target lesion/vessel revascularisation (TLR/TVR) and stroke. Results: There was higher incidence of MACCE in PCI group (18.1% vs. 9.5%, p=0.145). That was mainly because of higher incidence of MI (6% vs. 0%, p=0.021) and TLR/TVR (6% vs. 0%, p=0.021) in PCI group. There was no difference in mortality rate (9.6% in PCI group vs. 9.5% in CABG group, p>0.05). Age, fibrinogen, C-reactive protein were predictors of stent thrombosis, while left ventricular dilatation, EuroSCORE and SYNTAXscore were predictors of mortality in our study. Conclusion: There was no difference in mortality rate during 2-year follow-up after PCI and CABG in studied patients. Incidence of MI and TLR/TVR was higher after PCI comparing with CABG.
