Myocardial Infarction in Old People

Abstract

The clinical features and outcome were determined for 100 consecutive patients aged 65 years or older with a history of diabetes mellitus who presented to hospital with acute myocardial infarction. Each case was compared with an age- and sex-matched nondiabetic control also admitted to hospital with acute myocardial infarction. Chest pain was equally common in both groups and was the main presenting symptom. Cardiac failure was a more frequent accompaniment in the diabetics, despite the lack of evidence for greater infarct size in this group. The outcome was worst for female diabetics, of whom 46% died. Contrary to popular teaching, painless myocardial infarction is not a specific feature of elderly diabetics.
