The announcement of the new recommendation on daily low dose aspirin is very recent. The advice that I heard on not using aspirin to prevent clots with an afib episode is maybe 5 years old. I was told in 2015 to take full dose aspirin for a month after an episode. Noone says that now. Instead, they did an echo to check for clots after an episode. (I am not saying don't take it, and follow your own doc.)

From the web, explaining the different kinds of meds:
Anticoagulants such as heparin or warfarin (also called Coumadin) slow down your body's process of making clots. Antiplatelet drugs, such as aspirin, prevent blood cells called platelets from clumping together to form a clot.

More:
The similar bleeding risk combined with the questionable effectiveness for reducing stroke risk means aspirin is not a good option for most AFib patients. While aspirin may not be an effective approach to reducing stroke risk in AFib patients, it may still be prescribed as a treatment for other heart conditions.

Hi @hmccarth5. Wondering whether you thought you were taking Eliquis to prevent A-fib. I'm taking Coumadin for a different purpose -- to reduce chances for a clot to develop when A-fib causes blood to remain in an atrium of the heart long enough to clot there. When my pharmacologist suggested that I consider switching from Coumadin to Eliquis, I asked whether that would prevent A-fib events, and I was told by the doctors on my medical team that Eliquis is not a cure for A-fib, but only a preventive for clotting. They outlined options for A-fib therapy, one of which is based on medication, but not an anticoagulant, which Eliquis and Coumadin are. Like you perhaps, I have A-fib that is asymptomatic, but it shows up every time I have an electrocardiogram (EKG) at my HMO. My daily Coumadin apparently does nothing to cure the disease, but it keeps me free of blood clots. Martin
