Two-year clinical follow up of coronary drug-eluting stent in patients at high risk for coronary restenosis

OBJECTIVE: To evaluate the long-term follow up of patients at high risk for coronary restenosis. BACKGROUND: Drug-eluting stents (DES) have been proven to reduce restenosis and reintervention compared with bare-metal stents (BMS). Although the safety of DES is not different from that of BMS in the short-to-medium term, concern has arisen about the potential for late stent thrombosis related to delayed endothelialization of the stent struts. METHODS: Among 495 patients who underwent percutaneous coronary intervention between June 2004 and March 2005, we retrospectively identified a subset of 150 patients (30%) at high risk for coronary restenosis on the basis of angiographic characteristics …
