[Effectiveness of heparin in patients with acute myocardial infarction].

Clinical pattern and complications of the disease were studied in 62 heparin-treated patients with large-focal myocardial infarction as compared to a control group of 59 patients treated with a polarizing mixture of glucose, insulin, potassium, analgetics and tranquilizers. The changes of the necrotic area and lesion were assessed on the basis of precardiac charting. The results obtained were correlated to the data on central hemodynamics, heart contractility and pumping function, gaseous exchange and acid-base balance.
