Atrial fibrillation (AF) is the most frequent heart arrhythmia and causes a substantial proportion of ischemic strokes. AF has a marked impact on stroke severity, as well as on morbidity and mortality in these patients. The importance of AF as an etiologic factor of stroke increases in the elderly and in the last few years its detection has increased. The presence of AF leads to more severe initial neurological involvement, longer hospitalization, greater disability and a lower probability of discharge to home. In addition, AF is an independent risk factor for mortality, especially in women and the elderly. All these factors lead to a higher social and economic impact among stroke patients with AF.
心房颤动（AF）是最常见的心律失常，是导致相当一部分缺血性中风的原因。AF对中风严重程度以及这些患者的发病率和死亡率有显著影响。AF作为中风病因的重要性在老年人中增加，并且在过去几年中其检出率有所上升。AF的存在会导致更严重的初始神经功能受累、更长的住院时间、更大的残疾以及更低的回家出院概率。此外，AF是死亡率的独立危险因素，尤其是在女性和老年人中。所有这些因素导致AF中风患者产生更高的社会和经济影响。
