Abstract

Objectives The aim of this study was to evaluate the extent of neointimal response after the implantation of a second-generation drug-eluting stent, zotarolimus-eluting stent (ZES-ER, Endeavor Resolute) or everolimus-eluting stent (EES, Xience V), using intravascular ultrasound (IVUS) in diabetic patients. Materials and methods In all, 154 diabetic patients with de-novo coronary lesions were randomized to be implanted with a ZES-ER or EES, and the angiographic follow-up at 9 months combined with a complete IVUS study was available for 96 patients with 101 lesions. Results Baseline demographic and lesion parameters were similar in both groups at index percutaneous coronary intervention. On follow-up angiography, in-stent late lumen loss and minimal lumen diameter were not different between the two groups. On IVUS study, neointimal hyperplasia volume [median (interquartile range): ZES-ER vs. EES; 2.25 mm 3 (0.57-6.25) vs. 1.59 mm 3 (0.45-8.37), P=0.615] and in-stent percentage of volume obstruction [median (interquartile range): ZES-ER vs. EES; 1.16% (0.33-3.61) vs. 0.77% (0.29-4.01), P=0.615] showed similar results between the two groups. Conclusion In diabetic patients, the second-generation drug-eluting stents, ZES-ER and EES, were comparable in inhibiting neointimal proliferation.
