心房顫動（Atrial fibrillation, AF）會導致心房內血液滯留，極易形成血栓（Thrombus）。若血栓脫落並隨血液循環進入腦部，將造成缺血性中風（Ischemic stroke）。AF 是中風最強力的危險因子，其風險比一般人高出數倍。臨床上對於 AF 病人，抗凝血治療是預防中風的標準護理目標。
Atrial fibrillation (AF) causes blood to pool in the atria, predisposing the client to thrombus formation. If a thrombus is dislodged and travels through the circulation into the brain, an ischemic stroke results. AF is the strongest risk factor for stroke, increasing the risk by several times compared with the general population. Clinically, anticoagulation is the standard nursing goal for preventing stroke in AF clients.
