To determine the efficacy of multivessel coronary angioplasty, 569 consecutive patients undergoing multivessel angioplasty were compared with 569 age- and sex-matched control patients undergoing single-vessel angioplasty. Baseline variables were similar except for number of diseased vessels and greater left ventricular dysfunction in the multivessel group. Major in-hospital complication rates (death, 0% vs 0.5%; Q wave myocardial infarction, 0.5% vs 0.9%; emergency bypass surgery, 2.5% vs 3.2%) were similar for multivessel and single-vessel angioplasty. The 5-year actuarial survival rate was 93% for multivessel angioplasty and 92% for single-vessel angioplasty. Event-free survival was similar except that patients undergoing multivessel angioplasty had an 8% higher incidence of repeat coronary angioplasty in the first year of follow-up (p = 0.03). Multivessel coronary angioplasty can be performed with results comparable to those of single-vessel angioplasty with the exception of a higher incidence of repeat angioplasty.
