[The long-term success after coronary angioplasty in old age]

Long-term results of coronary angioplasty (CAP) were compared between two age-groups of patients. Group 1 had 227 patients (158 men, 69 women) with a mean age of 70 (65-88) years, group 2 had 717 patients (611 men, 106 women), mean age 54 (20-64) years. Unstable angina was more common in group 1 than group 2 (48.9 vs 37.7%, P < 0.05). Multi-vessel disease was present in 50.7% of those in group 1 and 41.9% in group 2. Primary success of CAP was similar in the two groups (group 1: 88.1%, group 2: 90.5%). The long-term effect at the first follow-up angiography 3-4 months after CAP was slightly less favourable in group 1 than 2 (54.9 vs 58.3%; difference not significant). However, there were more patients with unstable angina in group 1. Thus the angiographic long-term results were worse in the older patients (44.6 vs 60.1%; P < 0.05), while there was no difference between the two groups as regards stable angina (64.7 vs 57.2%). After a second CAP (because of recurrence), the long-term angiographic effect was, if anything, slightly better in the older patients (87.0 vs 77.1%). The death-rate (cardiac causes of death) up to one year after CAP was comparable in the two groups (1.7 vs 0.8%), as was the rate of non-fatal myocardial infarction (2.2 vs 1.3%). These data indicate that clinical and angiographic long-term success after CAP is comparable in older and younger patient groups and age alone does not present a higher risk.
