After a first myocardial infarction, the professional future of 86 patients is studied. 80 men and 6 women are included in the study. The mean age is 50.68 years. Manual workers prevail among affected patients, regardless of their age or of the site of the infarct. 78% of patients under 60 years resumed work, during the first threa months in more than half the cases, without any readjustments. The mean age of patients who resumed work is 47.6 years. Work was more often completely discontinued among office clerks and business managers than among other professions. Difficulties in finding readjusted jobs are greater for manual workers, especially if they belong to a small firm or if they are over 50. From a psychological and professional point of view, rehabilitation should be included in the management of myocardial infarction, even if it's impact on long-term mortality remains unknown.
