ABSTRACT
OBJECTIVE:
Acute myocardial infarction (AMI) is an important cause of mortality and morbidity in older patients. The aim of this study was to determine the proportion of unselected admissions with AMI that is older than 75 years and to examine management and outcomes in this group.DESIGN:
An historical cohort study of consecutive unselected admissions with AMI identified using the Hospital In Patient Enquiry (HIPE) database and validated according to MONICA criteria for definite or probable AMI.SETTING:
An acute cardiac unit in a university teaching hospital/cardiac tertiary referral center.RESULTS:
Of 1059 patients, 606 (57%) were older than 65 years and 309 (29.2%) were older than 75 years. Mean age in this group was 80.5 years. Hospital mortality was almost twice as high as in patients younger than 75 years (28% vs 15%, P < .001), and age was an independent predictor of short- and long-term mortality following AMI. Women constituted a significantly higher proportion of older patients. Family history of AMI and cigarette smoking were less prevalent in older patients. Mean cholesterol was lower and comorbidities were higher. Other baseline characteristics, including previous AMI, did not differ. However older patients were less likely to receive thrombolysis (13% vs 36%, P < .001), aspirin (76% vs 86%, P < .01), or beta-blockers (25% vs 51%, P < .001) and were less likely to undergo cardiac catheterization or revascularization. Only 53% were admitted to coronary care.CONCLUSION:
Patients more than age 75 comprise almost one-third of patients with AMI and have a poor prognosis. Although age is an independent predictor of mortality following AMI, suboptimal management may contribute to the high mortality in these patients.
