Effect of High-intensity Statin With Ezetimibe COmbination theRapy Versus High-intensity sTatin Monotherapy After Percutaneous Coronary Intervention With Drug-eluting Stents; the ESCORT Trial

All eligible patients who underwent coronary revascularization with newer generation DES implantation will be enrolled according to inclusion/exclusion criteria after voluntary agreement with informed consent. At the time of enrollment, we will stratify the patients according to LDL-cholesterol <100mg/dL, acute coronary syndrome, and DES type, and randomly assign them in two groups according to lipid-lowering therapy with a 1:1 ratio: "Combination therapy group" vs. "Statin monotherapy group". In this study, four types of new generation DES will be used: Orsiro (Biotronik), Firehawk (Microport), Genoss (Genoss) or D+Storm (CGBIO).

In this study, OCT substudy will be performed for the patients with diffuse long lesions requiring total stented length ≥30 mm (targeted for 700 patients in the trial). Corresponding patients will be randomly assigned into two groups according to the OCT-based optimal expansion criteria with a 1:1 ratio: meeting "Absolute expansion" vs. "Relative expansion". The absolute expansion criteria is defined as a minimum stent area (MSA) >4.5mm2, while the relative expansion criteria is defined as achieving an MSA ≥ 80% of the mean reference lumen area or ≥ 100% of the distal reference lumen area. The patients will receive DES implantation under OCT guidance and stent optimization will be performed to satisfy the assigned expansion criteria.
