Streptokinase in acute myocardial infarction: western Washington randomized trial--protocol and progress report

A randomized trial of intracoronary thrombolysis in a multicenter, geographically limited community has been undertaken. There have been no deaths or important morbidity because of heart catheterization. Preliminary data analysis has shown that patient entry within 3 hours of the onset of infarction has been the exception rather than the rule. It is anticipated that this trial will be completed by mid 1983. It is hoped that the data obtained from this study will help clarify the role of thrombolysis in acute myocardial infarction.
