During one year 279 patients were observed after myocardial infarction while working. Four clinical variants during the restorative period with concrete symptomatics have been isolated: the congestive cardiac insufficiency, angina pectoris, neurotic and with few symptoms. These symptoms can serve to differentiate selection of treatment and also to help the physician in selecting rehabilitation and to offer opinion as to prognosis.
