Key exclusion criteria
* Patient has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute myocardial infarction (MI)
* Patient has had a known diagnosis of recent MI (ie, within 72 hours 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 creatine kinase-myoglobin band (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 with unstable angina or 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 white blood cell (WBC) count <3,000 cells/mm3
* Patient has documented or suspected liver disease, including laboratory evidence of hepatitis
* Patient is on dialysis or has known renal insufficiency (ie, estimated creatinine clearance <50 ml/min by the Cockcroft Gault formula, or [(140-age)*lean body weight (in kg)]/[plasma creatinine (mg/dl)*72])
* Patient has history of bleeding diathesis or coagulopathy or will refuse blood transfusions
* Patient has had a cerebrovascular accident (CVA) or transient ischemic attack (TIA) within past 6 months, or has any permanent neurologic defect that may cause non-compliance with the protocol

* 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
* Planned PCI or CABG after index procedure
* Patient previously treated at any time with coronary intravascular brachytherapy
* Patient has a known allergy to the study stent system or protocol-required concomitant medications (eg, stainless steel, platinum, cobalt, chromium, nickel, tungsten, acrylic, fluoropolymers, everolimus, thienopyridines, aspirin, contrast) that cannot be adequately premedicated
* Patient has active peptic ulcer or active gastrointestinal (GI) bleeding
* Patient has one of the following.

* Other serious medical illness (eg, cancer, congestive heart failure) that may reduce life expectancy to less than 24 months
* Current problems with substance abuse (eg, alcohol, cocaine, heroin, etc.)
* Planned procedure that may cause non-compliance with protocol or confound data interpretation
* Patient is participating in another investigational drug or device clinical trial that has not reached its primary endpoint
* Patient intends to participate in another investigational drug or device clinical trial within 12 months after index procedure
* Patient with known intention to procreate within 12 months after index procedure (Women of child-bearing potential who are sexually active must agree to use a reliable method of contraception from the time of screening through 12 months after the index procedure.)
* Patient is a woman who is pregnant or nursing (A pregnancy test must be performed within 7 days prior to the index procedure in women of child-bearing potential)
