- (2)Patients who meet either of following criteria
  - ECG changes compatible with new ischemia [e.g. ST depression (at least 1 mm), T wave inversion (at least 2 mm), or hyperacute peaked T waves in 2 contiguous leads].
  - already elevated CK at least twice the upper limit of normal or CK-MB or Troponin I or T above the upper limit of normal or positive qualitative test for Troponin T.
- (3)A percutaneous coronary intervention is planned within 96 hours after the first study drug administration
