[Long-term prognosis of myocardial infarct].
The authors study the long-term prognosis of a population of male subjects having survived 24 to 48 hours to their first myocardial infarction. The mean annual mortality is 6%. The long-term cumulated survival is particualarly influenced by a high blood pressure and by heart failure occurring during the acute episode and in a lesser proportion by age; the prognosis at long-term is not or little influenced by family history, cholesterolemia, cigarette smoking or the presence of angina before infarction. The presence or absence of heart failure and high blood pressure allows to make sub-groups with very different long-term prognosis. In the framework of secondary prevention of ischaemic heart diseases, the authors propose to start a controlled study implying both a programme of physical activity and a long-term energical treatment of arterial hypertension.
