Increased operator experience and technologic advances have led to increased utilization of percutaneous transluminal coronary angioplasty1 (PTCA), but precise indications for this procedure in certain subsets of patients have not been adequately defined. Elderly patients are undergoing PTCA more often,2 yet there is little information regarding initial results, complication rates and long-term outcome in this group. Therefore, to evaluate the safety and efficacy of angioplasty in the elderly, we performed a retrospective review of all patients 75 years of age or older who underwent PTCA at our institution during a 3-year interval (January 1985 through November 1987). A similar number of patients (but younger than 75 years of age) who underwent PTCA during the same period were randomly selected for comparative purposes. This report summarizes the early and late results of PTCA in these patients.
