title: Comparison of results of coronary angioplasty for acute myocardial infarction in patients > or =75 years of age versus patients <75 years of age.
abstract: We reviewed 1,063 consecutive patients treated with direct coronary angioplasty for acute myocardial infarction (AMI): 261 were > or =75 and 802 were <75 years of age. Compared with the younger group, the older group had a higher percentage of women (48% vs 22%, p <0.0001), multivessel coronary disease (50% vs 39%, p <0.01), overall in-hospital mortality (8.4% vs 3.7%, p <0.01), cardiac mortality rate (6.1% vs 3.1%, p <0.05), and noncardiac mortality rate (2.3% vs 0.6%, p <0.05). Successful reperfusion was achieved in both groups at a similarly high rate (93% and 95%, p = NS). Hospital mortality was similar whether reperfusion was successful or failed. Successful compared with unsuccessful angioplasty decreased mortality rates in the older (6.6% vs 33%, p <0.0001) and younger (3.0% vs 18%, p <0.0001) groups. When reperfusion was successful, the cardiac mortality rate in older patients was not significantly higher than in younger patients: 4.1% vs 2.4%, p = NS.
