Summary
Compile acute (30-day) clinical outcomes data and 9-month angiographic and intravascular ultrasound (IVUS) data for the PROMUS Element™ Everolimus- Eluting Coronary Stent System in the treatment of patients with a single de novo atherosclerotic lesion
Eligibility Criteria
Inclusion Criteria
- Patient (or legal guardian) understands the study requirements and the treatment procedures and provides written informed consent before any study-specific tests or procedures are performed
- Patient is eligible for percutaneous coronary intervention (PCI)
- Patient has documented stable angina pectoris (Canadian Cardiovascular Society [CCS] Classification 1, 2, 3, or 4) or documented silent ischemia; or unstable angina pectoris (Braunwald Class IB-C, IIB-C, or IIIB-C)
- Patient is an acceptable candidate for coronary artery bypass grafting (CABG)
- Patient has a left ventricular ejection fraction (LVEF) >=30% as measured within 30 days prior to enrollment
- Patient is willing to comply with all specified follow-up evaluations
Angiographic Inclusion Criteria:
- Target lesion must be a de novo lesion located in a native coronary artery with visually estimated diameter of >=2.25 mm and =50% and 1.
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 (within 30 days prior to the index procedure) and has elevated enzymes at the time of the index procedure as follows.
- Patients are excluded if any of the following criteria are met at the time of the index procedure
- If creatine kinase, MB band (CK-MB) >2× upper limit of normal (ULN), the patient is excluded regardless of the creatine kinase (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, the patients are excluded if the following criterion is met at the time of the index procedure.
- Troponin >1× ULN with at least one of the following.
- Patient has ischemic symptoms and electrocardiogram (ECG) changes indicative of ongoing ischemia (e.g., >1mm ST segment elevation or depression in consecutive leads or new left bundle branch block [LBBB]);
- Development of pathological Q-waves in the ECG
- 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 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 the 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 (e.g., 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
- Patient has a platelet count 700, 000 cells/mm3
- Patient has a white blood cell (WBC) count =2.0 mm in diameter
- Involves a clinically significant side branch <2.0 mm in diameter that has a clinically significant stenosis at the ostium
- TIMI flow 0 (total occlusion) or TIMI flow 1 prior to wire crossing
- Excessive tortuosity proximal to or within the lesion
- Extreme angulation proximal to or within the lesion
- Target lesion and/or target vessel proximal to the target lesion is moderately to severely calcified
- Restenotic from previous intervention
- Thrombus, or possible thrombus, present in the target vessel
- Patient has an additional clinically significant lesion(s) in the target vessel for which an intervention within 12 months after the index procedure is likely to be required
