20891 patients who were admitted to hospital within 6 hr of the onset of symptoms of acute myocardial infarction were randomised to:

Thrombolysis:

  • streptokinase (1.5 MU over 30-50 min)
  • t-PA (100 mg over 3 hr)

Anticoagulation:

  • aspirin daily for 30 days (325 mg)
  • aspirin daily for 30 days plus subcutaneous heparin (12500 IU subcutaneous twice daily)

There were no significant differences in the 35 day mortality rates between:

  • streptokinase and t-PA
  • aspirin and aspirin+heparin

There was a small, but significant, increased incidence of stroke associated with t-PA.
