Angiographic Inclusion Criteria (visual estimate):

criteria)

criteria)

stenosis >=50% and <100% with Thrombolysis in Myocardial Infarction (TIMI)
flow >1.
Exclusion Criteria:
- Patient has clinical symptoms and/or electrocardiogram (ECG) changes consistent
with acute MI
- Patient has had a known diagnosis of recent MI (ie, within 30 days prior
to index procedure) and has elevated enzymes at time of index procedure as
follows:
- Patients are excluded if any of the following criteria are met at time
of the index procedure.
- If CK MB >2× upper limit of normal (ULN), the patient is excluded
regardless of CK Total.
- If CK MB is 1 2× ULN, the patient is excluded if the CK Total
is >2× ULN.
- If CK Total/CK MB are not used and Troponin is, patients are excluded
if the following criterion is met at time of index procedure.
- Troponin >1× ULN with at least one of the following.
- Patient has ischemic symptoms and ECG changes indicative of ongoing
ischemia (eg, >1 mm ST segment elevation or depression in consecutive
leads or new left bundle branch block [LBBB])
- Development of pathological Q waves in the ECG; or
- Imaging evidence of new loss of viable myocardium or new regional
wall motion abnormality.
Note: For patients who have had a recent MI, CK Total/CK MB (or Troponin if
CK Total/CK MB are not used) must be documented prior to enrolling/randomizing
the patient.
- Patient has received an organ transplant or is on a waiting list for an
organ transplant

before or after index procedure

inhaled steroids are not excluded) or has known life-limiting immunosuppressive
or autoimmune disease (eg, human immunodeficiency virus, systemic lupus erythematosus,
but not including diabetes mellitus)
- Patient is receiving chronic (>=72 hours) anticoagulation therapy (eg, heparin,
coumadin) for indications other than acute coronary syndrome

evidence of hepatitis

clearance <50 ml/min by the Cockcroft Gault formula, or [(140-age)*lean
body weight (in kg)]/[plasma creatinine (mg/dl)*72])

blood transfusions

- Target vessel(s) or side branch has been treated with any type of PCI (eg,
balloon angioplasty, stent, cutting balloon, atherectomy) within 12 months
prior to index procedure

lesion (by visual estimate) with any type of PCI (eg, balloon angioplasty,
stent, cutting balloon, atherectomy) at any time prior to index procedure
- Non-target vessel or side branch has been treated with any type of PCI (eg,
balloon angioplasty, stent, cutting balloon, atherectomy) within 24 hours
prior to index procedure
- Planned or actual target vessel(s) treatment with an unapproved device,
directional or rotational coronary atherectomy, laser, cutting balloon, or
transluminal extraction catheter immediately prior to stent placement
