[Venous treatment with streptase in acute myocardial infarct and unstable stenocardia (a new method)].

Streptokinase treatment was carried out in the intensive care unit of III Internal Clinic, the Higher Medical Institute--Plovdiv, on 54 patients, 51 of them with acute myocardial infarction (AMI) and 3 with intermediary coronary syndrome, making use of the preparations streptase (GFR) and avelysin (GDR). A control group of 35 patients with AMI was used. The treatment was initiated with stream administration of heparin 10,000 U and urbazon 20 mg, whereafter streptokinase 1,250,000 U per 1 h was included on that background. The results were determined according to ECG in 30 leads, recorded by 2, 4, 6, 12 and 24 h, according to creatine-phosphokinase activity and the outcome of the disease. The treatment was uninterrupted up to 24 h with the determination of the individual fibrinolytic activity. Normalization of S-T segment was established by 4 h with restoration of ECG in 10 patients, and in the rest--maintaining QS or QR forms. Re-perfusion arrhythmias were observed in 66.67% and data about re-thrombosis--in 13.61%. Lethality was 5.89%. The method is emphasized to be a reliable means for the treatment of AMI.
