心房纤颤(AF)病人的卒中发病率比一般人高5倍,此类病人更易发生心源性脑栓塞;虽然对心脏病应用抗凝剂预防脑栓塞的复发目前已获得普遍承认,但对用药开始时间、持续时间以及是普遍应用或选择应用则尚有争议,抗凝治疗应根据基本疾病而定已获公认。由于近来风湿性瓣膜性心脏病(RHD)已趋向减少,AF更常发生于非风湿性非瓣膜性心脏病(NVHD),推测系由于冠状动脉硬化与心房缺血所致。
Atrial fibrillation (AF) patients with stroke incidence of 5 times higher than the average person, such patients more prone to cardiogenic cerebral embolism; although the application of anticoagulant anticoagulant heart disease prevention of recurrent cerebral embolism has been generally recognized, but the use of drugs The timing of onset, duration, and the prevalence or choice of application are controversial and anticoagulant therapy should be established based on underlying disease. Due to the recent trend toward reduced rheumatic valvular heart disease (RHD), AF occurs more frequently in non-rheumatic non-valvular heart disease (NVHD), presumably due to coronary atherosclerosis and atrial ischemia.
