To identify the number of Northland stroke patients with atrial fibrillation (AF) and to assess the effective use of warfarin anticoagulation in this group
A retrospective study of patients admitted with stroke or transient ischaemic attack (TIA) to Whangarei Hospital between 1 Jan 2010 and 1 Sept 2010.
Of 198 stroke/TIA patients identified, 47 (24%) had confirmed persistent or paroxysmal AF (PAF) or flutter. Only 12 (31%) patients with pre existing PAF or AF were on warfarin and only 1 patient had an ischaemic stroke while in the therapeutic INR range of 2.0-3.0. The commonest reason cited for no anticoagulation was patients' wishes.
In our region, effective warfarin use for stroke prevention in AF patients is lower than recommended. This may be improved with increased awareness of efficacy and safety of warfarin and more thorough monitoring of INR.
确定北国地区患有心房颤动（AF）的中风患者数量，并评估该组患者对华法林抗凝治疗的有效使用情况。
对2010年1月1日至2010年9月1日期间因中风或短暂性脑缺血发作（TIA）入住旺阿雷医院的患者进行回顾性研究。
在确定的198例中风/TIA患者中，47例（24%）确诊患有持续性或阵发性房颤（PAF）或心房扑动。在已有PAF或AF的患者中，只有12例（31%）接受华法林治疗，且只有1例患者在国际标准化比值（INR）为2.0 - 3.0的治疗范围内发生缺血性中风。未进行抗凝治疗最常见的原因是患者的意愿。
在我们地区，华法林在房颤患者预防中风方面的有效使用率低于推荐水平。通过提高对华法林疗效和安全性的认识以及更全面地监测INR，这种情况可能会得到改善。
