Controlled trial of urokinase in myocardial infarction. A European Collaborative Study.

341 patients with acute myocardial infarction have been treated in intensive or coronary care units. They were randomised into two groups, 172 receiving urokinase and 169 receiving a glucose infusion. Thereafter they were anticoagulated first with heparin and then for a year with oral anticoagulants. Despite a significantly faster regression of electrocardiographic alterations in the urokinase group there was no difference in mortality during the 1-year follow-up (29 deaths in the urokinase and 24 in the control group) and no difference in cardiac functional class between both groups.
