Outcome Measures

Primary Outcomes (1)

  • The incidence of, and time to, the composite endpoint of death, nonfatal MI, recurrent myocardial ischemia, or need for coronary revascularization

    30 days

Secondary Outcomes (5)

  • The incidence of, and time to, the composite endpoint of death, nonfatal MI, recurrent myocardial ischemia, or need for coronary revascularization

    6 months

  • The incidence of myocardial necrosis (as detected by elevated cardiac troponin I or T).

    24 hours

  • The incidence of major (including non-CABG-related) and minor hemorrhage.

    48 hours and 30 days

  • The incidence of all-cause mortality, nonfatal MI, and the combination.

    30 and 180 days

  • One or more of the followings: hemodynamic instability, congestive heart failure, Clinical need for antithrombotic/antiplatelet therapy beyond aspirin, identifiable culprit lesion on diagnostic coronary angiography

NO INTERVENTION

Interventions

Enoxaparin will be given subcutanteously at a dose of 1mg/kg every 12 hours for a minimum of 48 hours (4 doses) and a maximum of 8 days until a diagnostic / therapeutic procedure is performed, or at the discretion of the investigator.

  • Renal insufficiency or renal dialysis;
  • A prosthetic heart valve;
  • Any other clinically relevant serious diseases;
  • Current evidence of inebriation with alcohol or intoxication resulting from other drug abuse;
  • Treatment with other investigational agents or devices within the previous 30 days, planned use of investigational drugs or devices, or has previously enrolled in this trial;
