title: Long-term outcome of percutaneous transluminal coronary angioplasty and coronary bypass surgery for multivessel coronary artery disease.
abstract: We studied the short- and long-term outcomes of 97 patients treated with percutaneous transluminal coronary angioplasty (PTCA) and 72 patients treated with coronary artery bypass graft surgery (CABG) for multivessel coronary artery disease in a single hospital in 1989. Patients treated with CABG had a higher angina class, a higher incidence of diabetes mellitus and a greater extent of the disease. Complete revascularization was achieved in 61 patients (85%) with CABG and in 45 patients (46%) with PTCA (p < 0.001). Initial success of PTCA and CABG was obtained in 95% and 94% of the patients with PTCA and CABG, respectively. Actuarial survival rates at 5 years were similar (96% in the PTCA group; 94% in the CABG group). Fewer patients suffered from cardiac death or myocardial infarction in the CABG group than in the PTCA group, but this difference was not significant. The rate of survival free from death, myocardial infarction, CABG and repeat PTCA, was significantly higher in the CABG group than in the PTCA group (85% vs 48%; p < 0.001). These results suggest that CABG provides a favorable long-term outcome in patients with multivessel coronary artery disease and that PTCA provides a similar outcome in these patients when applied to suitable lesions, although more patients who undergo PTCA require repeat procedures.
