OBJECTIVE - It is still controversial whether sirolimus-eluting stent (SES) and paclitaxel-elutingstent (PES) are equally effective in patients with diabetes. In these patients, multiple individual variables may be responsible for neointimal hyperplasia, thus making difficult the comparison of the two drug-eluting stents (DES). RESEARCH DESIGN AND METHODS- We designed a prospective, randomized study to compare the efficacy in prevention of restenosis of SES and PES, both implanted in the same diabetic patient with multiple de novo coronary intervention. We enrolled 60 patients with diabetes with at least two significant de novo angiographic stenoses in different coronary segements. The primary end point was in-stent late luminal loss (LLL) at 8-month angiographic follow-up. RESULTS - A total of 120 lesions were successfully treated with the randomly assigned DES (SES, n = 60; PES, n = 60). In-stent LLL was lower in the SES than in the PES group (0.26 +/- 0.4 vs.0.50 +/- 0.6 mm; P = 0.01). Coronary lesions treated with SES presented a reduced in-scent LLL in 40 (68%) patients, while PES resulted in a lower in-stent LLL in 19 (32%) patients (P = 0.0002). At multivariable analysis, the type of DES implanted was the only independent predictor of in-stent LLL (odds ratio 2.3 [95% CI 1.1-5.0]; P = 0.03). CONCLUSIONS- SES directly compared with PES in the same diabetic patient is associated with a decrease in the extent of in-stent LLL at 8 months, suggesting a reduced risk of restenosis.

Abstract

OBJECTIVE - It is still controversial whether sirolimus-eluting stent (SES) and paclitaxel-elutingstent (PES) are equally effective in patients with diabetes. In these patients, multiple individual variables may be responsible for neointimal hyperplasia, thus making difficult the comparison of the two drug-eluting stents (DES). RESEARCH DESIGN AND METHODS- We designed a prospective, randomized study to compare the efficacy in prevention of restenosis of SES and PES, both implanted in the same diabetic patient with multiple de novo coronary intervention. We enrolled 60 patients with diabetes with at least two significant de novo angiographic stenoses in different coronary segements. The primary end point was in-stent late luminal loss (LLL) at 8-month angiographic follow-up. RESULTS - A total of 120 lesions were successfully treated with the randomly assigned DES (SES, n = 60; PES, n = 60). In-stent LLL was lower in the SES than in the PES group (0.26 +/- 0.4 vs.0.50 +/- 0.6 mm; P = 0.01). Coronary lesions treated with SES presented a reduced in-scent LLL in 40 (68%) patients, while PES resulted in a lower in-stent LLL in 19 (32%) patients (P = 0.0002). At multivariable analysis, the type of DES implanted was the only independent predictor of in-stent LLL (odds ratio 2.3 [95% CI 1.1-5.0]; P = 0.03). CONCLUSIONS- SES directly compared with PES in the same diabetic patient is associated with a decrease in the extent of in-stent LLL at 8 months, suggesting a reduced risk of restenosis.
