Although an increased surgical risk of ischemic myocardial disease is widely accepted, amelioration of this risk after coronary artery bypass is poorly defined. We compared the outcomes of major elective general and peripheral vascular operations in 181 patients with prior coronary artery bypass grafting (CABG) with outcomes in an age-, gender-, and procedure-matched group without prior CABG (NOCABG). Despite the perception of a greater operative risk in the CABG patients (more CABG patients in American Society of Anesthesiologists [ASA] class III and fewer in ASA class I, p<0.001), mortality (1.1% CABG versus 2.8% NOCABG) and morbidity (18.8% CABG versus 18.5% NOCABG) rates in the two groups were not significantly different. For patients who have undergone successful CABG, it appears that: (1) the risk of subsequent elective major general and vascular surgical operations is similar to that of an age-, gender-, and procedure-matched cohort, and (2) the mortality rate after elective operations is low.
