Abstract

Six hundred and eighty four patients (629 men), all aged under 60 years, who had survived for 28 days after a first acute myocardial infarction were studied to determine the influence of the site of infarction on long term prognosis. The infarct site was not significantly related to age nor to extent of infarct at the time of the acute episode. Mechanical complications were more common in patients with anteroseptal infarctions, while atrioventricular conduction disturbances were more commonly found in those with inferior infarction. The site of infarction was not related to smoking habits or angina before the infarction or at 2 year follow up. Life table methods did not show any relation between infarction site and morbidity or mortality either two years or 15 years after the initial infarction.
