A retrospective study of myocardial infarction occurring in elderly patients in a coronary care unit.

Myocardial infarction is a major cause of morbidity and mortality particularly in the elderly. Coronary Care Unit monitoring has resulted in the improvement in prognosis in all age groups. In this study, the clinical course and outcome of 204 consecutive patients with acute myocardial infarction aged over 65 years is retrospectively analysed. All patients were managed in a Coronary Care Unit operating a needs related policy. Those under 75 years (120 patients) were compared to those over that age (84 patients). The groups differed in terms of clinical presentation, cardiac enzymatic rise and response to drug therapy. However they had similar complication rates, morbidity and mortality.
