We report on 345 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) for stable angina in a 5-year period, with an average follow-up of 34 months (range 12-72). The primary success rate was 94.5%. The late mortality and incidence of myocardial infarction were 1.5% and 2.1% respectively. The rate of recurrence of angina was 34.5% and required PTCA (28.5%) and/or coronary artery bypass grafting (7%). At the end of follow-up 79.5% of patients were free from angina and a further 10% had improved. Our data confirm the importance of PTCA in stable angina.
