    Abstract:
    We analyzed the long-term outcome of 198 patients after unsuccessful percutaneous transluminal coronary angioplasty. Forty-nine percent underwent emergency coronary artery bypass grafting surgery, 17% had elective bypass surgery, and 34% were treated medically. The in-hospital mortality rate was 4%, and myocardial infarction occurred in 36% of patients. Follow-up was completed in 100% of patients with a mean follow-up period of 35 +/- 22 months. Actuarial cardiac survival at 4 years was 97% in the emergency bypass surgery group, 100% in the elective bypass surgery group, and 86% in the medically treated group. Actuarial event-free survival (freedom from myocardial infarction, bypass surgery, coronary angioplasty, and cardiac death) at 4-year follow-up was 81% in 198 patients, 90% in the emergency bypass surgery group, 85% in the elective bypass surgery group, and 65% in the medically treated group. Results of multivariate analysis showed that emergency or elective bypass surgery after failed coronary angioplasty, normal or mildly impaired left ventricular function, and male sex were predictors of better outcome at 4 years.
