Intervention Model: Single Group Assignment
Masking: None (Open Label)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with clinically significant de novo coronary artery disease
  • Stenting only with Endeavor® stents
  • The sum of stent length is less than 60 mm for one lesion. The sum of stent length in multiple lesions does not matter.

Exclusion Criteria:

  • Cardiogenic shock
  • ST-elevation myocardial infarction within 48 hours of symptom onset
  • Prior implantation of drug-eluting stents
  • Left ventricular dysfunction (echocardiographic left ventricular ejection fraction < 25%)
  • Stenting both branch of bifurcation lesion
  • Left main trunk lesion
  • Graft vessels
  • Patients who have to receive clopidogrel due to other conditions
  • Patients who have to receive warfarin, cilostazol or other antiplatelet therapy
  • Patient with chronic renal failure (S-Cr > 2.0 mg/dl)
  • Hypersensitivity to clopidogrel or aspirin
  • Expectant survival less than 1 year
  • Women who plan to become pregnant
  • Patients with bleeding diathesis (coagulopathy, thrombocytopenia or platelet dysfunction, Gastrointestinal or genitourinary bleeding within the prior 3 months)
  • Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
