Abstract 4415: Comparison of Subsequent Vascular Response in Diabetic Patients Following Coronary Stenting Between Sirolimus- and Paclitaxel-Eluting Stents: Optical Coherence Tomography Analysis
Background: Diabetes mellitus is one of the major predictors for target lesion revascularization even in drug-eluting stent era. The aim of this study is to evaluate the differences of chronic vascular response in patients with diabetes mellitus (DM) following coronary stenting between sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES) using optical coherence tomography (OCT).
Methods: We examined non-restenotic 60 SESs and 60 PESs were imaged with motorized OCT pull-back system (1 mm/s) at 9-month follow-up and analyzed at interval of 1 mm. Neointimal coverage of stent struts and the incidence of stent malapposition were evaluated.
Results: See table⇓.
Conclusions: SES could not prevent neointimal growth in DM group. However, subsequent vascular response after PES implantation in DM group was similar to that in non DM group. OCT findings
