摘要

Background Preinfarction angina improves survival after acute myocardial infarction (AMI) in nonelderly but not elderly patients in the thrombolytic era. However, it remains unclear whether preinfarction angina has a beneficial effect on clinical outcome in elderly patients undergoing percutaneous coronary intervention (PCI). Methods and Results The study group comprised 484 anterior AMI patients who were admitted within 24 h of onset and underwent emergency PCI. Patients were divided into 2 groups: those aged <70 years (nonelderly patients, n=290) and those aged >/=70 years (elderly patients, n=194). Angina within 24 h before AMI was present in 42% of nonelderly patients and in 37% of elderly patients. In nonelderly patients, preinfarction angina was associated with a lower in-hospital mortality rate (1% vs 7%, p=0.02). Similarly, in elderly patients, preinfarction angina was associated with a lower in-hospital mortality rate (6% vs 16%, p=0.03). Multivariate analysis showed that the absence of preinfarction angina was an independent predictor of in-hospital mortality in both nonelderly (odds ratio 4.20; 95% confidence interval (CI) 1.20-10.6; p=0.04) and elderly patients (odds ratio 3.04; 95%CI 1.06-18.1; p=0.04). Conclusions Angina within the 24 h before AMI is associated with better in-hospital outcomes in elderly and nonelderly patients. (Circ J 2005; 69: 630 - 635).
