排除标准
- •Subject has clinical symptoms and/or electrocardiogram (ECG) changes consistent with acute myocardial infarction (MI).
- •Subject with unstable angina or recent MI (clinically diagnosed within 3 days) must have creatine kinase (CK)/ creatine kinase-myoglobin band(CK-MB) or troponin documented prior to the procedure and are excluded if any of the following criteria are met at the time of the index procedure:
- •If CK MB >2× upper limit of normal (ULN), the subject is excluded regardless of the CK Total.
- •If CK Total >2× ULN, CK-MB must be drawn and the subject is excluded if CK-MB is abnormal.

- •Development of pathological Q waves in the ECG or;
- •Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality Note: Subjects who do not have unstable angina or recent MI must still have CK/CK-MB drawn prior to the index procedure. However, the results for these subjects do not need to be available prior to the index procedure and there are no exclusion criteria based on these studies.
- •Subject is receiving chronic (≥72 hours) anticoagulation therapy (e.g., heparin, coumadin) for indications other than acute coronary syndrome.

- •Subject has had a cerebrovascular accident (CVA) or transient ischemic attack (TIA) within the past 6 months, or has any permanent neurologic defect that may cause non-compliance with the protocol.

- •Target vessel has been treated within 10 mm proximal or distal to the target lesion (by visual estimate) with any type of PCI (e.g., balloon angioplasty, stent, cutting balloon, or atherectomy) at any time prior to the index procedure.
- •Non-target vessel or side branch has been treated with any type of PCI (e.g., balloon angioplasty, stent, cutting balloon, atherectomy) within 1 day prior to the index procedure.
- •Note: 1 lesion in a non-target vessel may be treated during the index procedure prior to the treatment of the target (study) lesion.
- •Planned or actual target vessel 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 the index procedure.
- •Subject previously treated at any time with coronary intravascular brachytherapy.
- •Subject has known allergy to the study stent system or protocol-required concomitant medications (e.g., stainless steel, platinum, chromium, nickel, iron, thienopyridines and acetylsalicylic acid (ASA)) and contrast (that cannot be adequately premedicated).
- •Subject has any other serious medical illness (e.g., cancer, congestive heart failure) that may reduce life expectancy to less than 12 months.
- •Subject has current problems with substance abuse (e.g., alcohol, cocaine, heroin, etc.).
- •Subject has a planned procedure that may cause non-compliance with the protocol or confound data interpretation.
- •Subject is participating in another investigational drug or device clinical trial that has not reached its primary endpoint or intends to participate in another investigational drug or device clinical trial within 12 months after the index procedure.
- •Subject is female of childbearing potential with a positive pregnancy test within 14 days before the index procedure, is lactating, or intends to become pregnant during the study.
- •Subject has more than 1 target lesion, or more than 1 target lesion and 1 non-target lesion, which will be treated during the index procedure.
- •Angiographic Exclusion Criteria:
- •Target lesion meets any of the following criteria:
- •Aorto-ostial location (i.e., lesion located within 5 mm of the ostium by visual estimate)
- •Left main location
