Purpose

The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions.

Exclusion Criteria:

  • 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
  • Patient is receiving or scheduled to receive chemotherapy within 30 days before or after index procedure
  • Patient is receiving oral or intravenous immunosuppressive therapy (ie, 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
