心房颤动(AF)常伴有体循环栓塞(SE)。在脑血管意外中,6～23%的中风系由心源性栓子引起,其中几乎一半是AF病人,且以二尖辫狭窄者最为多见。业已证实,孤立性AF和伴有冠状动脉疾病、毒性甲状腺肿、体循环高血压及左房扩张等AF病人,其SE发生率亦较高。本文对272例无二尖瓣狭窄的AF病人进行了长期随访研究,旨在评价此种病人SE的危险因素。方法:研究对象为经超声心动图(UCG)检查排除了人工瓣膜或二尖瓣狭窄且均符合随访要求的272例AF病人。除病人死亡或12月内有栓塞发生者仍列为随访对象外,余随访时间均>12月。应用 Atrial fibrillation (AF) is often accompanied by systemic embolism (SE). In cerebrovascular accidents, 6-23% of strokes are caused by cardiogenic emboli, almost half of them being AF patients and most commonly seen with spiked stenosis. It has been confirmed that solitary AF and associated with coronary artery disease, toxic goiter, systolic blood pressure and left atrial expansion and other AF patients, the incidence of SE is also higher. In this paper, 272 patients with non-mitral stenosis in patients with long-term follow-up study of AF to assess the risk factors for SE in such patients. Methods: The subjects were 272 AF patients who underwent echocardiography (UCG) examination that excluded prosthetic valves or mitral stenosis and were eligible for follow-up. Except for the death of the patient or the occurrence of embolism in December is still included in the follow-up, the remaining follow-up time> 12 months. application
