The drug-eluting stents reduce restenosis rate compared to bare metal stents. The clinical efficacy is greater in some subgroups of patients at high risk of restenosis. The aim of this study is to evaluate the use of drug-eluting stent based on the recommendations of the French Society of Cardiology and his impact on the restenosis rate at 2 years. We included all patients who had coronary angioplasty with stenting in 2008. We evaluated the percentage of drug-eluting stent, the proportion of patients for which the French recommendations have been followed, and the rate of clinical restenosis at 2 years. Four hundred and seventy-nine angioplasties were performed in 2008. The percentage of drug-eluting stents was 21.8%. Acute coronary syndrome with or without elevation of the ST segment were the main indications of angioplasty (67.9%). For the 115 drug-eluting stents implanted in 2008, French recommendations were followed in 93% of cases (107 stents). For 89 patients who received DES, these recommendations were followed in 91% of cases (81 patients). The clinical restenosis rate at two years evaluated in 89% of patients was 5.6%. The rate of in-stent restenosis in bare metal and drug-eluting stents were 5.9% and 3.7%. The use of DES in our center is characterized by a small rate and a good compliance of the recommendations of the French Society of Cardiology. This strategy is associated with a low rate of restenosis at 2 years of follow-up.
