ABSTRACT
In 212 patients aged 75 years and older the immediate and long-term results of percutaneous transluminal coronary angioplasty (PTCA) were assessed. For 293 stenoses the primary angiographic success rate was 96% and the overall clinical success rate was 90.6%. Angioplasty caused a myocardial infraction in 7 patients (3.3%), 2 patients (0.9%) needed emergency aorto coronary bypass surgery, and 4 patients (1.9%) died following the procedure. Actuarial 7 year survival was calculated at 69.3% with a standard deviation (SD) of 8%. Actuarial cardiac survival at 7 years was 92.1% (SD 3%), whereas non-cardiac survival at 7 years was 75.3% (SD 9%). Actuarially, at 7 years 98.5% (SD 1%) were estimated to remain free from myocardial infarction in the angioplasty-related area, 95.7% (SD 2%) to remain free from any myocardial infarction, 93.9% (SD 2%) to remain free from re-PTCA because of a recurrence, 84.7% (SD 5%) to remain free from any re-PTCA, and 97.1% (SD 2%) to remain free from (re)-operation. Fifty-two point three percent (SD 8%) were estimated to remain free from any cardiac event. If recurrence of angina is taken into account, only 25.8% (SD 13%) remain asymptomatic during 7 years follow-up. After successful angioplasty in patients aged 75 and older the chance of remaining free from any event or angina at 7 years actuarial follow-up gets as low as 15.7% (SD 9%). We conclude that in selected elderly patients angioplasty can be performed with a high success rate, although the periprocedural mortality and morbidity appear to be higher than in the younger age group. During long-term follow-up, most of the patients remain free of cardiac events and survival appears to be largely dependent on noncardiac factors. However, long-term relief from angina is probably less than in younger patients.
