ABSTRACT
Eleven patients underwent thrombolytic therapy with streptodekase-1 and 19 with streptodekase-2. Of these, 11 patients suffered acute myocardial infarction, 10 had unstable angina pectoris, 6 thromboembolism of the pulmonary artery, 2 thromboembolism of the peripheral arteries and 1 thrombosis of the femoral vein. Administration of streptodekase-2 brought about an increase of the total blood fibrinolytic activity (the fibrinolysis time dropped from 248.8 +/- 82.1 to 137.5 +/- 42.5 min after 12 h), plasmin activation (from 0.00 +/- 0.00 to 23.5 +/- 7.5 mg after 24 h), reduction of the plasminogen content (from 94.0 +/- 2.5 to 46.8 +/- 5.3% after 12 h). The parameters of the coagulation hemostasis did not undergo any appreciable changes. Fibrinolysis activation following streptodekase-2 administration was unchanged within the first 48 hours. No material differences were identified in fibrinolysis activation in patients given streptodekase-2 and streptodekase-1. Administration of streptodekase-2 was found to exert a marked beneficial clinical effect on acute myocardial infarction, unstable angina pectoris, thromboembolism of the pulmonary and peripheral arteries.

Clinical course of the disease and the formation of the necrotic focus (as evidenced by precordial mapping from 35 ECG leads) were assessed in 88 patients with acute myocardial infarction, treated with 1,000,000 IU urokinase, in comparison to 41 untreated control patients. Thrombolytic therapy, started within the first 6 hours of myocardial infarction, was associated with a better clinical course of the disease. Urokinase administration after 6 hours from the onset of the symptoms produced no clinical improvement, did not limit the necrotic focus and failed to reduce mortality, as compared to the controls. The assessment of the efficiency of thrombolytic treatment demonstrated an at least 30% increment of venous flow in 45% of patients. Intravenous urokinase administration was accompanied by an activation of blood fibrinolytic system, and there was a tendency to fibrinolysis depression on the day following the administration.
