Abstract: Introduction: Percutaneous coronary intervention (PCI) has been increasingly performed to treat coronary artery disease. The performance of multiple PCI has also been increasing. Consequently, the percentage of patients presenting for coronary artery bypass graft (CABG) surgery is reported to vary from 13 to 40%. The influence of previous PCI on CABG outcomes has been studied in single center, regional studies, registries and meta-analyses. Some reports showed a negative effect on mortality and morbidity in early or long-term follow-up, but others did not find this influence. Methods and Results: A cohort of 3007 patients consecutively operated for CABG, 261 of them with previous PCI, were included in this analysis. Comparison of the groups ""previous PCI"" and ""primary CABG"" was made in the original cohort and in a propensity score matched cohort of 261 patients. There were some differences in preoperative clinical characteristics in both types of cohort, even in the matched one. Outcomes were compared at 30 days, 1 year and 5 years of follow-up. There were no statistically significant differences in mortality in any period or cohort. There were some differences in other outcomes as readmission and composite events, including cardiovascular death at 1 and 5 years of follow-up. These differences, neverthless, were not confirmed in comparison with the matched cohort. Conclusion: Although there are some limitations in this study, it was not found consistent negative influence of previous PCI on CABG.
