慢性心房纤颤是老年人新发生血栓栓塞性卒中的一个独立的危险因素,其发生率随年龄的增长而递增。颅外颈动脉疾病(ECDA)是老年人新发生粥样硬化性脑梗死的一个独立的危险因素。作者对1846名老年人平均随访了45个月,前瞻性地研究报告了慢性心房纤颤和ECAD(管腔狭窄40％～80％)与新发生血栓栓塞性卒中发生率之间的关系。
Chronic atrial fibrillation is an independent risk factor for new-onset thromboembolic stroke in the elderly, and its incidence increases with age. Extracranial carotid disease (ECDA) is an independent risk factor for new-onset atherosclerotic cerebral infarction in the elderly. The authors followed an average of 1846 elderly patients for 45 months and prospectively reported the relationship between chronic atrial fibrillation and ECAD (stenosis of 40% to 80%) and the incidence of thromboembolic stroke.
