非瓣膜性房颤（NVAF）是心源性脑卒中的重要危险因素，与卒中死亡风险独立相关。目前，对NVAF 导致心源性卒中的机制尚未完全阐明，有研究表明一些生物标志物和风险评分可以预估NVAF相关脑卒中 的发生发展。本文对NVAF患者发生脑卒中的相关危险因素进行综述。

Nonvalvular atrial fibrillation (NVAF) is an important risk factor for cardiogenic stroke and is independently associated with stroke death. Mechanism of NVAF leading to cardiogenic stroke has not been fully elucidated, and studies have shown that some biomarkers and risk scores can predict the occurrence and development of NVAF related stroke. This article reviews the relevant risk factors for stroke in NVAF patients.
