Atrial fibrillation detected after stroke

Atrial fibrillation is one of the important risk factors for ischemic stroke, which can lead to the cardioembolic stroke. On the contrary, ischemic stroke can also result in atrial fibrillation, namely, atrial fibrillation detected after stroke (AFDAS). Studies have shown that the pathophysiological mechanism and prognosis of AFDAS may be different from those of atrial fibrillation known before stroke. The monitoring of AFDAS and its effect on prognosis has become a hot research topic. This article reviews the definition, pathophysiological mechanism, monitoring methods and prognosis of AFDAS.
