[Effect of the characteristics of the preinfarct period on the state of patients in the 1st year after a myocardial infarct].
From a follow-up of 496 patients (males aged from 20 to 65 years) the authors analyse their condition during the first year after recovery from myocardial infarction. It is shown that preceding arterial hypertension, a history of myocardial infarction and angina pectoris as well as the patient's elderly age have an unfavourable effect with regard to the possible development of circulatory insufficiency during the first year after myocardial infarction which must, without doubt, be taken into account in planning regimens of motor activity for these patients. An unfavourable prognostication factor with regard to the hazard of a new myocardial infarction developing during the first year is a recurrent affection of the cardiac muscle, and in patients of the 60--65 year group, the existence of hypertension prior to myocardial infarction.
