COmparison and Modification in Neointimal Pattern Assessed by Optical Coherence Tomography With High Versus Moderate Efficacy Statin Treatment After Drug Eluting Stent Implantation: COMPASS Trial

July 26, 2016 updated by: Yonsei University
This study is a prospective randomized trial to evaluate and compare the quantitative and qualitative characteristics of neointimal formation between high and low efficacy statin treatment after drug eluting stent (DES) implantation, in patients with homogeneous or heterogeneous neointimal pattern accessed by Optical Coherence Tomography (OCT). The investigators postulate that high efficacy statin could have superior effect on modification of neointimal pattern, compared with lower efficacy statin. Our main hypothesis is that Atorvastatin 40mg, high efficacy statin might have superior effect on modification of neointimal pattern evaluated by serially followed OCT, compared with pravastatin 20mg in patients with DES implantation.
