In recent years, there has been a nationwide trend toward performing percutaneous transluminal coronary angioplasty in patients with multivessel coronary artery disease. The clinical course of 57 consecutive patients who required emergency first-time coronary artery bypass grafting operations were reviewed to assess for difference in outcome between the 28 patients (49%) with single-vessel disease and the 29 patients (51%) with multivessel disease. The two groups were similar in preoperative characteristics except for a higher proportion of chronic obstructive pulmonary disease in the patients with multivessel disease (p = 0.03). Twice as many patients with multivessel disease were in shock (single-vessel disease = 4 [14%], multivessel disease = 8 [28%], p = not significant) en route to the operating room and significantly more patients with multivessel disease required on-going cardiopulmonary resuscitation (single-vessel disease = 0 [0%], multivessel disease = 5 [17%], p = 0.03). Significantly more coronary artery bypass grafts were placed in the patients with multivessel disease (single-vessel disease = 1.5 +/- 0.6, multivessel disease = 2.9 +/- 0.7, p < 0.01), which required longer aortic clamping time (p = 0.02) and cardiopulmonary bypass time (p < 0.01). There were seven postoperative deaths; all but one occurred in patients with multivessel disease (single-vessel disease = 1 [4%], multivessel disease = 6 [21%], p = 0.05). According to multivariate analysis, incremental risk factors of mortality were preoperative shock (p < 0.01), urgent or emergency percutaneous transluminal coronary angioplasty (p = 0.06), and multivessel disease (p = 0.12). Despite a similar incidence of myocardial infarction (single-vessel disease = 8 [29%], multivessel disease = 12 [41%], p = not significant), patients with multivessel disease had a higher incidence of cardiac morbidity (single-vessel disease = 4 [14%], multivessel disease = 11 [38%], p = 0.04) and noncardiac morbidity (single-vessel disease = 4 [14%], multivessel disease = 12 [41%], p = 0.02). By multivariate analysis, incremental risk factors of morbidity were preoperative shock (p < 0.01), multivessel disease (p = 0.02), and ejection fraction < 50% (p = 0.07). In the subset of patients with multivessel disease, preoperative shock, ejection fraction < 50, and an age of 60 years or greater were associated with higher morbidity and mortality. In conclusion, the risk of percutaneous transluminal coronary angioplasty failure is considerably higher in patients with multivessel disease. In certain subsets of patients with multivessel disease, coronary artery bypass grafting would be a safer procedure when compared with percutaneous transluminal coronary angioplasty for initial myocardial revascularization.
