摘要 目的本研究通过比较初始剂量3mg和5mg对NVAF患者抗凝作用的影响,了解国人的华法林最佳起始剂量,为临床进一步合理应用华法林提供更多证据。方法选取2004年7月至2005年12月就诊的卒中中危或高危NVAF患者173例,所有患者随机分入3mg治疗组和5mg治疗组。两组患者均调整华法林剂量,使INR维持于2.0~3.0。随访2个月,观察两组患者达稳定INR所需时间、发生INR增高、主要出血/血栓栓塞事件的差异。结果两组基线特征差异无显著性。3mg治疗组达稳定INR的时间与5mg组相似。3mg治疗组的INR增高发生率显著低于5mg组。5mg治疗组有5例发生轻微出血(牙龈/鼻腔)(6.9%),两组间差异有显著性。结论对于中国NVAF患者,应用华法林以3mg为初始剂量是安全、可行的,与5mg相比,疗效相似而INR过高的发生明显减少。3mg可能是国人NVAF应用华法林的更佳初始剂量。
