Summary

Objectives 1. 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) 2. 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 1. Non-inferiority of Promus Element stent compared with Endeavor Resolute stent in reducing target lesion failure (TLF) 2. 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 1. 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 2. 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
