title: Efficacy of intracoronary and intravenous urokinase in acute myocardial infarction.
abstract: The efficacy of intracoronary and intravenous urokinase was studied in 83 patients with acute evolving myocardial infarction. Urokinase was administered intracoronary in 48 patients with a success rate of 89% obtained after 47 +/- 32 minutes of infusion of a dose of 255.000 +/- 224.000 IU. In-hospital mortality in this group of patients was 10%. Severe arrhythmias were observed in 33% of the patients and the reocclusion rate at the re-study was 16%. Intravenous urokinase was administered as 200.000 IU bolus followed by 1.220.000 IU infusion in 21 patients. Angiography performed in this group of patients 48 hours after therapy showed a patency rate of 66%. A single intravenous bolus of 500.000 IU of urokinase was administered to 14 patients. At angiography all patients but one were found reperfused. The value of intravenous low-dose bolus injection of urokinase in acute myocardial infarction needs hower to be assessed with a properly designed clinical trial.
