The aim of this study was to investigate the impact of previous repeated PCI on the subsequent coronary artery bypass grafting CABG . Methods Between January 1990 and January 2008 a total of 894 patients underwent first-time isolated elective CABG. Among the 894 patients 515 patients had had no PCI group A 179 patients had had single PCI Group B and 200 patients had had multiple PCI 2-15 times mean times group C before CABG. These groups were compared in terms of early and late clinical results. Results Preoperative left ventricular ejection fraction was significantly higher in group A group A 58 13 group B 54 12 and group C 54 12 . Number of bypass grafts was significantly smaller in group C A B C . Although there was no statistically significant difference among the groups in-hospital mortality in group C was higher than that in group A and B A B C p . Survival analysis by Kaplan-Meier method mean follow-up 58 43 methods revealed that freedom from all-cause death and cardiac death was significantly lower in group C in comparison with group A. Freedom from cardiac event was significantly higher in group C than that in group A. Multivariate analysis identified a number of previous PCI as an independent risk factor for cardiac death. Conclusions Repeated PCI increased risk for long-term prognosis of subsequent CABG.
