The good news I can offer, is I have been in and out of permanent AFib for 15 years and have been on Warfarin even when not known to be in AFib and I no blood clots have ever been detected. Some people have trouble with
Warfarin, it takes a very regular
diet to hold steady. Aspirin us usually, I believe, used if the patient can tolerate, taken with food I think most of us can. Warfarin requires reglar blood coagulation tests, aspirin doesn't.
