AIMS: Patients with diabetes mellitus have increased risk of in-stent restenosis after coronary stent implantation due to neointimal hyperplasia (NIH). The aim of this study was to use quantitative coronary angiography (QCA) and volumetric intravascular ultrasound (IVUS) to evaluate the effects of the sirolimus-eluting Cypher® stent (SES) and the zotarolimus-eluting Endeavor® stent (ZES) on angiographic late lumen loss and intima hyperplasia in diabetic patients. METHODS AND RESULTS: In the DiabeDES III trial, 127 patients were randomised to SES or ZES stent implantation. Angiographic 10-month follow-up data were available in 105 patients, including 48 SES and 57 ZES treated patients. Angiographic endpoints were in-stent late lumen loss and minimal lumen diameter. IVUS endpoints included NIH volume and in-stent percent volume obstruction. Baseline clinical characteristics and lesion parameters were similar in the two groups. At 10-month follow-up, angiographic in-stent late lumen loss (0.14±0.37 mm vs. 0.74±0.45 mm, p<0.001) was reduced and minimum lumen diameter was higher (2.36±0.53 mm vs. 1.96±0.65, p<0.001) in the SES group as compared to the ZES group. As compared to the ZES group, NIH volume was significantly reduced in the SES group (median [interquartile range]: 0.0 mm3 [0.0 to 1.2] vs. 16.5 mm3 [6.2 to 31.1], p<0.001). In-stent% volume obstruction was significantly reduced in SES as compared to ZES (median [interquartile range]: 0.0% [0.0-0.7] vs. 13.0% [6.7-20.8], p<0.001). CONCLUSIONS: In diabetic patients, the SES reduced angiographic late lumen loss and inhibited NIH more effectively than ZES.
