AIMS: Recent studies suggested that abciximab reduces the risk of restenosis in diabetic patients receiving coronary bare metal stent. We sought to evaluate whether abciximab may reduce in-segment late luminal loss (LLL), in patients with diabetes mellitus undergoing elective drug-eluting stents (PES) implantation. METHODS and RESULTS: We conducted a prospective, randomized, double-blind study on diabetic patients after a paclitaxel-eluting stent (PES) implantation on de novo coronary artery lesions. 132 consecutive patients with diabetes (mean age 63.1+/-7.4 years, 82 males) were randomized to abciximab (n=66) or placebo (n=66). Among the 124 (93.9%) patients who underwent a 6-months angiographic follow-up, the mean difference in in-segment LLL between patients who received abciximab and placebo was 0.02 mm (P=0.8). In addition, the rates of angiographic in-segment restenosis were comparable between the two groups (14.3 versus 9.8%, P=0.5). Cumulative rates of clinical events did not differ (death: 1.5 versus 1.5, P=0.9 and MI: 1.5 versus 3%, P=0.8) between abciximab and placebo group, respectively. Similarly, the incidence of target lesion revascularization was 9.1% and 6.1% (P=0.7) at six months, in the two groups. CONCLUSIONS: Abciximab does not seem to have any impact on the extent of in-segment LLL in diabetic patients undergoing an elective PES implantation.

Abstract
AIMS: Recent studies suggested that abciximab reduces the risk of restenosis in diabetic patients receiving coronary bare metal stent. We sought to evaluate whether abciximab may reduce in-segment late luminal loss (LLL), in patients with diabetes mellitus undergoing elective drug-eluting stents (PES) implantation. METHODS and RESULTS: We conducted a prospective, randomized, double-blind study on diabetic patients after a paclitaxel-eluting stent (PES) implantation on de novo coronary artery lesions. 132 consecutive patients with diabetes (mean age 63.1+/-7.4 years, 82 males) were randomized to abciximab (n=66) or placebo (n=66). Among the 124 (93.9%) patients who underwent a 6-months angiographic follow-up, the mean difference in in-segment LLL between patients who received abciximab and placebo was 0.02 mm (P=0.8). In addition, the rates of angiographic in-segment restenosis were comparable between the two groups (14.3 versus 9.8%, P=0.5). Cumulative rates of clinical events did not differ (death: 1.5 versus 1.5, P=0.9 and MI: 1.5 versus 3%, P=0.8) between abciximab and placebo group, respectively. Similarly, the incidence of target lesion revascularization was 9.1% and 6.1% (P=0.7) at six months, in the two groups. CONCLUSIONS: Abciximab does not seem to have any impact on the extent of in-segment LLL in diabetic patients undergoing an elective PES implantation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
