ABSTRACT
OBJECTIVE: To evaluate the use of percutaneous transluminal coronary angioplasty (PTCA) and the immediate procedural outcomes in the elderly at a tertiary care centre. PATIENTS AND METHODS: Between January 1992 and December 1997, a total retrospective cohort study of 2322 consecutive patients aged 60 years or older underwent PTCA. Patients were categorized into three age groups: group A (60 to 69 years of age), which included 1294 patients; group B (70 to 79 years), which included 895 patients; and group C (80 years of age or older), which included 133 patients. PTCA was performed using the newest catheter technology as it became available. RESULTS: Men comprised 63% of the patients in groups A and B combined, and 44% of group C (P<0.001). Canadian Cardiovascular Society angina class IV was present in 45% of group C compared with 30% and 35% in groups A and B, respectively (P<0.001). The proportion of patients with diabetes mellitus and hypertension was similar among the three groups. Acute myocardial infarction before PTCA was twice as common at 4.5% (95% CI 3.7% to 5.3%) in group C, compared with 2.9% (95% CI 2.7% to 3.1%) and 2.2% (95% CI 2.0% to 2.3%) in groups A and B, respectively. The procedural success rate was similar at 93%, 92.7% and 91.7% in groups A, B and C, respectively. A total of five (0.2%) deaths and eight (0.34%) myocardial infarctions occurred in groups A and B combined, while none occurred in group C (not significant). More patients in groups A and B underwent emergency coronary artery bypass graft than in group C: group A - 22, 3.4% (95% CI 3.2% to 3.6%); group B - 16, 3.4% (95% CI 3.2% to 3.6%) and group C - one, 0.75% (95% CI 0.6% to 0.9%). CONCLUSIONS: In this retrospective series of patients, it was shown that PTCA may be performed in the very elderly with high procedural success and acceptable risk. Age alone should not be the criterion to limit the use of PTCA.
