The average stent length is longer and the average stent diameter is shorter in patients with drug-eluting stents versus bare-metal stents during percutaneous coronary intervention.

摘要

Drug-eluting stents (DES) were inserted in 180 patients (270 stents), mean age 63 years, and bare-metal stents (BMS) were inserted in 191 patients (301 stents), mean age 63 years, during percutaneous coronary intervention. Baseline characteristics were similar for patients treated with DES or BMS. The average stent length was longer for DES (16.83 mm) versus BMS (15.45 mm) (P = 0.0026). The average stent diameter was shorter for DES (2.89 mm) versus BMS (3.00 mm) (P = 0.00027). In-hospital stent thrombosis occurred in one of 270 DES (0.4%) versus three3 of 301 BMS (1.0%) (P = not significant).
