To compare the long-term outcome after percutaneous coronary intervention with onew-generation drug-eluting stents (n-DES) to oolder generation DES (o-DES), and bare-metal stents (BMS) in a real-world population. less thanbrgreater than less thanbrgreater thanWe evaluated 94 384 consecutive stent implantations (BMS, n 64 631; o-DES, n 19 202; n-DES, n 10 551) in Sweden from November 2006 to October 2010. All cases of definite stent thrombosis (ST) and restenosis were documented in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Older generation DES were classified as: Cypher and Cypher Select (Cordis Corporation, Miami, FL, USA), Taxus Express and Taxus Libert (Boston Scientific Corporation), and Endeavor (Medtronic Inc.) and n-DES as: Endeavor Resolute (Medtronic Inc.), XienceV, Xience Prime (Abbott Laboratories) and Promus, Promus Element (Boston Scientific Corporation). The Cox regression analyses unadjusted and adjusted for clinical and angiographic covariates showed a statistically significant lower risk of restenosis in n-DES compared with BMS [adjusted hazard ratio (HR) 0.29; 95 confidence interval (CI): 0.250.33] and o-DES (HR 0.62; 95 CI: 0.530.72). A lower risk of definite ST was found in n-DES compared with BMS (HR 0.38; 95 CI: 0.280.52) and o-DES (HR, 0.57; 95 CI: 0.410.79). The risk of death was significantly lower in n-DES compared with o-DES (adjusted HR: 0.77; 95 CI: 0.630.95) and BMS (adjusted HR: 0.55; 95 CI: 0.460.67). less thanbrgreater than less thanbrgreater thanPercutaneous coronary intervention with n-DES is associated with a 38 lower risk of clinically meaningful restenosis, a 43 lower risk of definite ST, and a 23 lower risk of death compared with o-DES in this observational study from a large real-world population.

Safety and efficacy of drug-eluting vs. bare metal stents in patients with diabetes mellitus : long-term follow-up in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR)

AIMS: Patients with diabetes mellitus have more extensive coronary artery disease, more disease progression, and restenosis. The use of drug-eluting stents (DES) in these patients is widespread, despite uncertain long-term safety and efficacy. METHODS AND RESULTS: All consecutive patients with diabetes mellitus in Sweden who underwent percutaneous coronary intervention were entered into the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) during 2003-06 with complete follow-up for 1-4 years (median 2.5). Patients who received at least one DES (n = 4754) were compared with those who received only bare metal stents (BMS) (n = 4956) at the index procedure. Combined outcome of death or myocardial infarction (MI) showed no difference for DES vs. BMS, relative risk (RR), 0.91 [95% confidence interval (CI), 0.77-1.06]. Myocardial infarction was significantly less common with DES in patients who received only one stent RR, 0.80 (95% CI, 0.66-0.96). The restenosis rate was 50% lower in DES-treated patients RR, 0.50 (95% CI, 0.35-0.70) and was associated with a higher adjusted RR of MI, RR, 5.03 (95% CI, 4.25-5.97). DES was associated with reduced restenosis rates in all subgroups of diabetic patients with the greatest benefit in stent diameters <3 mm or stent length >20 mm. The number of lesions treated with DES to prevent one restenosis ranged from 11 to 47 in various subgroups. CONCLUSION: This real-life registry study shows that restenosis was halved by DES in diabetic patients with stable or unstable coronary disease, with similar risk of death or MI up to 4 years compared with BMS.
