The choice for oral anticoagulant (OAC) therapy was previously limited to the vitamin K antagonists (VKAs). The advent of the direct oral anticoagulants (DOACs) brought with it the expectation that oral anticoagulation would become simpler (with the elimination of routine monitoring and introduction of a fixed-dose anticoagulant), and that the use of VKAs would be slowly phased out. Although DOACs have made anticoagulation more convenient and accessible, we are now faced with what can be described as a tyranny of choice, together with many unanswered questions relating to DOAC use. These include optimal DOAC selection and dosing, use in complex 'real-world' patients, the role for monitoring and issues surrounding adherence. Warfarin remains the anticoagulant of choice in certain scenarios (e.g. metallic heart valves). The future holds much excitement: clinical studies are underway to expand the indications for DOACs and experience continues to grow outside the trials setting.
口服抗凝剂(OAC)治疗以前仅限于维生素K拮抗剂(VKA)。直接口服抗凝剂(DOAC)的出现带来了这样的期望:口服抗凝治疗将变得更简单(无需常规监测并引入固定剂量抗凝剂),并且VKA的使用将逐步淘汰。尽管DOAC使抗凝治疗更方便且更易获得,但我们现在面临着可以说是选择的困境,以及许多与DOAC使用相关的未解决问题。这些问题包括最佳DOAC选择和剂量、在复杂“现实世界”患者中的使用、监测的作用以及依从性相关问题。华法林在某些情况下(如金属心脏瓣膜)仍是首选抗凝剂。未来令人期待:正在进行临床研究以扩大DOAC的适应症,并且在试验环境之外的经验也在不断积累。
