Objective. The widespread use of percutaneous coronary intervention (PCI) has resulted in an increasing number of patients who have undergone prior PCI being referred for coronary artery bypass grafting (CABG). The aim of this study was to determine the association between previous PCI and early and midterm outcomes after CABG. Methods. A total of 54 patients undergoing elective CABG (group 1) between January 2008 and January 2009 were compared to 46 patients who had a history of bare metal stent implantation before CABG (group 2). Mean follow-up was 12 months. Results. The average time interval to CABG following initial PCI was 18.5 months. There was no significant difference in demographic features and risk factors between the two groups (p>0.05). There were also no significant differences in intraoperative and postoperative data, and no significant differences for in-hospital mortality, cardiac mortality and total mortality and in the number of rehospitalizations for cardiac or for all-cause reasons (p>0.05). Conclusion. In this study, previous PCI did not significantly influence the outcomes of CABG in a 12-month follow-up period.
