Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Onset of symptoms of AMI within six hours prior to randomisation
  • A twelve-lead electrocardiogram with one of the following: ST-segment elevation ≥ 0.1 millivolt (mV) in two or more limb leads, or ≥ 0.2 mV in two or more contiguous precordial leads indicative of AMI, or left bundle-branch block
  • Age ≥ 18
  • Informed consent received

Exclusion Criteria:

  • Hypertension defined as blood pressure > 180/110 mm Hg (systolic BP >180 mm Hg and/or diastolic BP >110 mm Hg) on repeated measurements during current admission prior to randomization
  • Use of abciximab (ReoPro ®) or other glycoprotein-IIb/IIIa antagonists within the preceding 7 days
  • Major surgery, biopsy of a parenchymal organ, or significant trauma within 2 months
  • Any minor head trauma and any other trauma occurring after onset of the current myocardial infarction
  • Any known history of stroke or transient ischemic attack or dementia
  • Any known structural damage of the central nervous system
  • Prolonged cardiopulmonary resuscitation (>10 minutes) in the previous two weeks
  • Current oral anticoagulation
  • Standard unfractionated heparin (heparin sodium) >5000 IU or a subcutaneous dose within 6 hours of randomization of a therapeutic dose of any low molecular weight heparin
  • Known thrombocytopenia (prior platelet count below 100000 cells/μl (100 x10**9/l))
  • Known renal insufficiency (prior S-creatinine >2.5 mg% (>220 μmol/l) for men and >2.0 mg% (>175 μmol/l)) for women
  • Pregnancy or lactation, parturition within the previous 30 days. Women of childbearing potential must have a negative pregnancy test, or use a medically accepted method of birth control
  • Treatment with an investigational drug under another study protocol in the past 7 days
  • Previous enrollment in this study
  • Known sensitivity to TNK-tPA, tPA, abciximab, heparin or low molecular weight heparin
  • Any other condition that the investigator feels would place the patient at increased risk if the investigational therapy is initiated
  • Inability to follow protocol and comply with follow-up requirements
