From 1982 to 1984 included, 31 patients under 70 years of age were admitted during the first three hours of a primary myocardial infarction (MI) and are the subject of a randomized prospective study. 16 patients are treated with 5,000 U of heparin given in intravenous bolus, followed with 150,000 IU of urokinase (UK) in intravenous bolus, then 12,000 IU of UK/min for 90 min or a total dose of 1,230,000 IU. 15 patients are treated with heparin alone (intravenous bolus of 5,000 U). Repeated titrations of creatine phosphokinase (CPK) and the coagulation parameters are performed during the first 24 hours. A coronary angiography with ventriculography (RAO 30 degrees) is performed on the 1st day (D1) and the 3rd week (W3). Study of the left ventricular kinetics (LV) is carried out according to the Stanford method. At D1, the rate of coronary patency is 56 p cent (n = 9) in the UK (A) group and 53 p. cent (n = 8) in the control group B (heparin alone). The percentage of late re-thrombosis is 0 p. cent in group A and 12.5 p. cent in group B (heparin alone). 1 patient died in each group. The CPK peak is less high in case of coronary patency in group A than in case of thrombosis (1,444 +/- 413 vs 1,710 +/- 120 U -heparin alone) and occurs earlier (16 +/- 2 h vs 21 +/- 1 h). In group A a significant decrease of fibrinogen (p. 0.01) as well as plasminogen and alpha-2-antiplasmins (p less than 0.001), is noted. No severe haemorrhagic complications nor sustained rhythm disorders are noted.(ABSTRACT TRUNCATED AT 250 WORDS)
