Opis

Inclusion Criteria:

  • Subjects greater than or equal to 18 years of age undergoing cardiac catheterization with planned percutaneous coronary intervention (if coronary anatomy is suitable) for an indication of chest pain +/or anginal equivalent felt by the treating physician to be related to coronary ischemia.

  • At least one of the following (a through c):

    1. Functional study (exercise, or pharmacologic) within the past 8 weeks consistent with ischemia as manifested by at least one of the following:

      1. A reversible defect on nuclear imaging.
      2. A reversible wall-motion abnormality by echocardiography.
      3. Horizontal or down-sloping ST-depressions greater than 1 mm on electrocardiogram (ECG) (if no imaging performed).
    2. Prior coronary revascularization [percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG)].
    3. A cardiac catheterization with at least one coronary artery lesion amenable to PCI (not yet performed) within 14 days prior to enrollment.

Exclusion Criteria:

  • Known creatine kinase-myocardial bands (CK-MB)or cardiac troponin greater than the upper limit of normal at time of screening
  • Planned PCI for acute myocardial infarction (MI) or planned PCI within 48 hours of fibrinolytic therapy for ST segment elevation myocardial infarction (STEMI)
