Purpose
Objectives
- To compare the safety and long-term effectiveness of coronary stenting with the new platform Everolimus-Eluting coronary stenting system (EECSS, Promus Element) compared with the Zotarolimus-Eluting coronary stenting system (ZECSS, Endeavor Resolute) in patients with coronary heart disease (CHD)
- To determine the short-term efficacy and safety of triple anti-platelet therapy (TAT, Aspirin 100mg qd, Clopidogrel 75mg qd and Cilostazol 100mg bid) compared with double-dose clopidogrel dual anti-platelet therapy (DDAT, Aspirin 100mg qd and Clopidogrel 150mg qd) in patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES)
Study design Prospective, open-label, 2-by-2 multifactorial, randomized, multicenter trial to test the following in CHD patients
- Non-inferiority of Promus Element stent compared with Endeavor Resolute stent in reducing target lesion failure (TLF)
- Non-inferiority of TAT compared with DDAT in reducing net clinical outcome Patients will be randomized in a 2-by-2 factorial manner according to the type of drug eluting stent (EECSS vs. ZECSS) and the type anti-platelet regimen (TAT vs. DDAT). Randomization will also be stratified per presence of DM.
Patient enrollment 3750 patients enrolled at 50 centers in Republic of Korea
Patient follow-up Clinical follow-up will occur at 1, 3, 12, 24, 36 months after the procedure. Angiographical follow-up will be recommended to all participants at 13 months after the procedure. Investigator or designee may conduct follow-up as telephone contacts or office visits.
Primary endpoint
- Target lesion failure (TLF), defined as a composite of cardiac death, target vessel-related myocardial infarction (MI) and ischemia-driven target lesion revascularization (TLR) up to 12 months for the stent arm
- Net clinical outcome, defined as a composite of cardiac death, nonfatal MI, CVA and major bleeding by PLATO criteria at 1 month for the anti-platelet arm

- Subject must be at least 18 years of age.
- Subject is able to verbally confirm understandings of risks, benefits and treatment alternatives of receiving the Promus Element or Endeavor Resolute stents, and he/she or his/her legally authorized representative provides written informed consent prior to any study related procedure.
- Subject must have significant lesion (>50% by visual estimate) in any of the coronary arteries, venous or arterial bypass grafts.
- Subject must have evidence of myocardial ischemia (e.g., stable, unstable angina, recent infarction, silent ischemia, positive functional study or a reversible changes in the electrocardiogram (ECG) consistent with ischemia). In subjects with diameter stenosis > 70%, evidence of myocardial ischemia does not have to be documented.
Angiographic Inclusion Criteria
- Target lesion(s) must be located in coronary artery, venous or arterial bypass graft with diameter of ≥ 2.5 mm and ≤ 4.00 mm.
- Target lesion(s) must be amenable for percutaneous coronary intervention.
Exclusion criteria

Those with true anaphylaxis to prior contrast media, however, should not be enrolled.)
- Systemic (intravenous) Everolimus or Zotarolimus use within 12 months.
- Female of childbearing potential, unless a recent pregnancy test is negative, who possibly plan to become pregnant any time after enrollment into this study.
- History of bleeding diathesis, known coagulopathy (including heparin-induced thrombocytopenia), abnormal hemogram (Hb<10g/dL or PLT count <100,000/μL) or will refuse blood transfusions
- Patients with severe LV systolic dysfunction (LVEF<25%) or cardiogenic shock
- Gastrointestinal or genitourinary bleeding within the prior 3 months, or major surgery within 2 months.
- Non-cardiac co-morbid conditions are present with life expectancy <1 year or that may result in protocol non-compliance (per site investigator's medical judgment).

- Symptomatic heart failure
