Abstract

To compare the presenting complaint, risk factors, and outcome of suspected acute coronary syndrome (ACS) in those aged 65 and older with those of a younger cohort.

Prospective observational cohort study.

A typical Scottish district general hospital covering a population of 150,000.

Patients presenting with suspected ACS (N=869) over a 6-month period.

Main presenting complaint and major risk factors including electrocardiogram (ECG) changes. Primary outcome measures were percutaneous coronary intervention, recurrent myocardial infarction, and death at 3-month follow-up.

Four hundred seventy-seven (55%) were aged 65 and older. Older patients were less likely to present with chest pain and more likely to present with breathlessness or collapse. They had fewer major risk factors for heart disease. There was a higher proportion with ischemic ECG changes, elevated troponin, and major acute coronary events at follow-up. Older patients were less likely to be accepted for angiography even though they were more likely than the younger cohort to have significant coronary artery disease when angiography was performed (chi-square test, P <.01 for all above).

Older patients with suspected ACS were more likely to present atypically and have worse outcomes than their younger counterparts, despite having fewer major risk factors. The results highlight the importance of age as a predictor of adverse outcome and suggest that clinicians need to ensure equitable access to angiography for older patients.
