Stents rarely thrombose in the first 24 hours after implantation; secondly, heparin has some influence on the extrinsic pathway. Additionally, if too much heparin is present it interferes with the INR, and the half life of prothrombin suggests that the patient should be anticoagulated with heparin for up to 96 hours after starting warfarin. This is the evidence on which our standard protocol is based.
支架在植入后的最初24小时内很少形成血栓;其次,肝素对外源性途径有一定影响。此外,如果存在过多肝素,会干扰国际标准化比值(INR),并且凝血酶原的半衰期表明,在开始使用华法林后,患者应使用肝素抗凝长达96小时。这就是我们标准方案所依据的证据。
