Abstract

To analyze the clinical and anatomic findings of patients undergoing coronary angioplasty for mild angina, and determine the short- and long-term outcome, a retrospective data bank analysis of 3,729 patients who underwent coronary angioplasty at the Mayo Clinic between July 31, 1980 and January 30, 1991 was performed. Of these patients, 217 (6%) had stable Canadian Heart Association class I or II angina at the time of the procedure and constitute the study population. Patients were followed for a median of 37 months after the procedure. The mean age of patients was 60 years; 82% were men. Prior myocardial infarction occurred in 22% of patients. Multivessel disease was present in 68% of patients, and mean left ventricular ejection fraction was 65 ± 11%. Angioplasty was clinically successful in 196 patients (90%), 271 of 318 lesions (85%) were successfully dilated. There were no in-hospital deaths. Coronary artery bypass was performed during hospitalization in 12 patients (5.5%), and myocardial infarction occurred in 3 (1.4%); bypass or infarction occurred in 13 patients (5.9%). During follow-up of the 196 successfully treated patients, there were 9 deaths (4.5%), 16 patients (7%) developed myocardial infarction, 30 (15%) underwent coronary artery bypass surgery, and 36 (17%) developed severe angina. The probability of having any of these adverse cardiac events after 6-year follow-up was 39%; an additional 24% of patients developed recurrent mild angina during follow-up. It is concluded that mild stable angina was an infrequent indication for coronary angioplasty at the Mayo Clinic. Although coronary angioplasty was successful in most patients with mild angina, and complications were infrequent, most patients developed recurrent mild angina or had an adverse cardiac event during 6-year follow-up.
