Health Conditions Featured There is little rationale for prescribing aspirin, rather than either warfarin or DOACs, to prevent thromboembolism related to atrial fibrillation, even if bleeding is a concern. The ACC/AHA/HRS 2014 Guidelines (14) give tepid support to the use of aspirin in patients with low risk (CHA 2 DS 2 -VASc ≤1) of thromboembolism—"aspirin may be ...In atrial fibrillation or atrial flutter, the atria do not empty completely into the ventricles with each beat. Over time, some blood inside the atria may stagnate, and blood clots may form. Pieces of the clot may break off, often shortly after atrial fibrillation converts back to normal rhythm—whether spontaneously or because of treatment.
