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
