Septic emboli from the vegetation will possibly result in systemic thromboembolism with multiple organ infarction. 另外细菌赘生物所掉落的感染性血栓也可能导致全身性的血栓栓塞，进一步导致多重器官衰竭。
Antiplatelet agents are not as effective as warfarin in reducing the risk of thromboembolism in patients with AF. 抗血小板制剂不能象华法林那样在房颤病中有效地减少血栓栓塞的危险。
