@dannydamon I could't figure out how to reply to you on the Mayo Clinic Discussion. I would have a discussion with the cardiologist who has been following you since you left the hospital and ask him if you still have Afib. The can do a holter monitor test where they monitor you for 24 hours or even a week to see if you still have Afib. If you don't have it then you can see if there is any reason why you need to stay on Warfarin. I was put on xarelto instead of warfarin because I couldn't manage taking it 4 times a day. Good luck. If you do have Afib, there are a couple of procedures they can do to reverse it. Most people don't have symptoms so you might still have it.
