Coronary Artery Disease
Conditions
Brief summary
This study is designed as a prospective, randomized, multi-center trial to demonstrate an inequality between IVUS-guided versus angiography-guided implantation of everolimus-eluting stents(EES) at long lesions(\> 28 mm) in clinical outcomes at 12 months as a primary objective and safety of 6- month dual antiplatelet therapy following EES implantation in comparison with a 12-month dual antiplatelet therapy.
Detailed description
The primary purpose of this study is to investigate the impact of IVUS guidance on the clinical outcomes after implantation of DES at long lesions \> 28 mm.
Interventions
Patients will be randomized in a two-by-two factorial manner according to the use of IVUS guidance (IVUS guidance vs. no IVUS guidance) for the PCI and the duration of dual anti-platelet therapy (100 mg/day aspirin and 75mg/day clopidogrel for 6 months vs. 12 months) after PCI. Each randomization of the enrolled subjects will be done 1:1.
