Eligibility
Key inclusion criteria
INCLUSION CRITERIA:

Patients with ST-segment elevation acute myocardial infarction meeting all of the following criteria:

* Male or non-pregnant female greater than or equal to 18 years of age (depending on local regulations, minimal age can vary between 18 and 21 years)
* Onset of prolonged (greater than or equal to 20 min) ischemic symptoms at rest less than or equal to 6 hours prior to randomization
* ST-segment elevation of 0.1 mV in 2 or more limb leads, or 0.2 mV in two (2) or more contiguous precordial leads, or left bundle-branch block
* Planned reperfusion therapy with streptokinase, tenecteplase, alteplase or reteplase
* Written informed consent will be obtained

EXCLUSION CRITERIA:

Cardiovascular

* Evidence of cardiogenic shock at randomization
* Acute pericarditis
* History or symptoms suggestive of aortic dissection
* MI precipitated by obvious provoking factors such as arrhythmia, infection, severe anemia, hyperthyroidism, cocaine, or amphetamine

Hemorrhagic Risk

* Any minor head trauma or any other trauma occurring after the index acute myocardial infarction
* Active or recent (< 3 months) bleeding including gastrointestinal bleeding, known presence of occult blood in the stool, or gross hematuria.
* Any history of bleeding diathesis, coagulopathy, platelet disorder, or thrombocytopenia
* Any single reliable recording of systolic blood pressure >180 mm Hg and/or diastolic blood pressure >110 mm Hg prior to randomization
* Any history of stroke or transient ischemic attack; any history of hemorrhagic cerebrovascular disease
* Any known structural damage or other pathologic process involving the central nervous system
* Any head trauma within 6 months prior to randomization
* Major surgery (including CABG), any ophthalmologic surgery, or non-cutaneous biopsy, or substantial trauma within 3 months prior to randomization
* Traumatic or prolonged cardiopulmonary resuscitation (> 2 minutes) within 2 weeks prior to randomization
* Puncture of a non-compressible vessel (artery or vein) within the 24 hours prior to randomization
* Acute peptic ulcer disease within 3 months prior to randomization

Prior or Concomitant Pharmacologic Therapy

* Administration of abciximab (ReoPro), within the previous 7 days or eptifibatide (Integrilin), or tirofiban (Aggrastat) within the previous 24 hours prior to randomization
* Current therapy with oral anticoagulants, or an International Normalized Ratio of >1.5
* Administration of a low molecular weight heparin within 8 hours prior to randomization.
* Known hypersensitivity to low molecular weight heparins, unfractionated heparin or heparin-like products; allergy to pork or pork products
* Known hypersensitivity and/or contra-indication(s) to fibrinolytic drugs (streptokinase, tenecteplase, alteplase and reteplase)

General

* Known clinically significant anemia (Hemoglobin <10 g/dL which is < 6.2 mmol/L)
* Known renal insufficiency with serum creatinine >220 mmol/L (2.5 mg/dL) for men and >175 mmol/L (2.0 mg/dL) for women when assessed prior to baseline examination.
* Advanced neoplastic or other life-threatening disease with a life expectancy of <12 months
* Pregnancy or parturition within the last 90 days or currently breast feeding
* Women of childbearing potential except if post-menopausal, surgically sterile or using accepted method(s) of birth control or having a negative pregnancy test.
* Treatment with other investigational agents in the last 30 days before study entry or previous enrollment in ExTRACT-TIMI 25
* History of drug or alcohol abuse
* Mental condition rendering the patient unable to understand the nature, scope, and possible consequences of the study
