Abstract： @@ The application of drug-eluting stent (DES), either sirolimus-eluting stent (Cypher, Cordis, USA) or paclitaxel-eluting stent (Taxus, Boston Scientific, USA), in treatment of patients with coronary artery disease (CAD) has achieved great success.1-4 The high cost of imported DES (either Cypher or Taxus) gave the birth to a China-made, polymer-based, sirolimus-eluting stent (Firebird, Microport Company, China). In March 2003, China Food and Drug Administration approved the clinical use of Firebird stent. However, the safety and efficacy of Firebird stent in comparison with Cypher and Taxus stents are still underestimated.
