This study examines the influence of a successful PCI upon preoperative patient profile, peroperative management and postoperative, including one-year follow-up, results. From January 1999 through December 2001, 1141 patients (91%) underwent coronary artery bypass grafting (CABG) as the primary intervention for myocardial revascularization (group A) and 113 patients (9%) underwent primary CABG after an initially successful PCI (group B). Patients undergoing CABG after a failed PCI were not

Left main coronary artery stenosis was significantly lower in group B (Ps0.004). The number of diseased vessels did not differ between the two groups. However, less distal anastomoses were performed in group B (Ps0.001). Postoperatively there was no statistically significant differences, in the percentages of myocardial infarction, arrhythmias, reinterventions, neurological, renal and pulmonary complications, and hospital mortality. One-year follow-up did not show any statistically significant differences in cardiac related mortality (Ps0.25) or recurrent ischemic events (Ps0.27). Multivariate analysis did not identify a successful PCI as a risk factor for early and late adverse outcomes. Previous PCI does not seem to result in a higher postoperative mortality or morbidity after CABG.
