BACKGROUND: Among patients in need of coronary revascularization before an elective vascular operation, the value ofcoronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) in preventing perioperative myocardial infarctions is uncertain. We hypothesized that more complete revascularization would improve outcomes after vascular surgery. METHODS: In this Veterans Affairs Cooperative trial involving 18 medical centers, 222 patients underwent elective vascular surgery after coronary revascularization. The mode of coronary revascularization was selected at each site by the local investigators (CABG in 91 patients and PCI in 131 patients). The vascular surgical indications were similar in both groups. RESULTS: There were 2 deaths in the CABG group (2.2%) and 5 deaths in the PCI group (3.8%; p = 0.497) after the vascular procedure. There were fewer perioperative myocardial infarctions after the vascular operation in CABG patients (6.6%) than in PCI patients (16.8%; p = 0.024), despite more diseased vessels in the CABG group (3.0 +/- 1.3 versus 2.2 +/- 1.4, respectively; p < 0.001). The completeness of revascularization (defined as the number of coronary artery vessels revascularized relative to the total number of vessels with a stenosis > or = 70%) in patients in the CABG and PCI groups was 117% +/- 63% and 81% +/- 57%, respectively (p < 0.001). Hospital length of stay in CABG versus PCI patients was 6 (4, 8) and 7 (4, 10) days, respectively (p = 0.078). CONCLUSIONS: Among patients receivingmultivessel coronary artery revascularization as prophylaxis for elective vascular surgery, patients having a CABG had fewer myocardial infarctions and tended to spend less time in the hospital after the vascular operation than patients having a PCI. More complete revascularization accounted for the intergroup differences.
