The authors investigated the efficacy and prognosis of emergency percutaneous trans luminal coronary angioplasty (PTCA) in elderly patients. A study was conducted on the early and late prognosis of the study group composed of 66 younger patients < sixty-five years in Group A and 46 elderly patients seventy years in Group B who underwent reperfusion therapy, including PTCA, for acute myocardial infarction (AMI). No difference was seen in the initial success rate of 82% for Group A and 85% for Group B, or in the vessel patency in the predischarge coronary arteriogram (CAG) with 84% for Group A and 87% for Group B. However, in-hospital mortality was 3% for Group A and 11% for Group B.

The patient restenosis rate in the 4.2 months follow-up CAG was 28% for Group A and 50% for Group B. The lesion restenosis rate was 30% for Group A and 53% for Group B (P < 0.05), and the late period mortality rate was 3% for Group A and 11% for Group B. Although there was no difference in the initial success rate of reperfusion through PTCA for AMI in the elderly as compared with the younger patient group, poorer results were seen in the restenosis rate and mortality rate.
