[Impact of prior percutaneous coronary intervention on outcome of coronary artery bypass graft surgery].

Objective: To determine the impact of prior percutaneous coronary intervention (PCI) on outcome of coronary artery bypass graft (CABG) surgery.

Methods: Perioperative data were collected from 1306 patients undergoing CABG from January 2002 to November 2010, including 117 patients with prior PCI and 1 189 patients without prior PCI. Among 117 patients with prior PCI, 99 patients had a single PCI procedure and 18 had multiple PCI procedures. The surgical outcomes including in-hospital mortality and major adverse cardiac events were compared between two groups.

Results: Patients with prior PCI were younger, less likely to have triple vessel and left main stem disease, and less recent myocardial infarction. Interval time between PCI and CABG was (13.39 ± 13.81) months. There were no significant difference in in-hospital mortality (1.7% compared with 0.5 % P=0.156) and major adverse cardiac events (including postoperative myocardial infarction, stroke, and in-hospital death,2.6% compared with 1.1% P=0.167) between two groups.

Conclusion: There was no association between prior PCI and isolated CABG. Good outcomes can be obtained in the group of patients undergoing CABG who have had previous PCI.
