[Impact of prior percutaneous coronary intervention on outcome of coronary artery bypass graft surgery].
ABSTRACT To determine the impact of prior percutaneous coronary intervention (PCI) on outcome of coronary artery bypass graft (CABG) surgery.
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.
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.
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.
