[|Human|] i am a 39 yr old 6 2 275 male with a history of atrial fib. recently i had a pulmonary vein ablation. The other morning i woke up with blood on my pillow and when i went to spit it was a blood clot. this happenned 2 days in a row. what is the problem?
[|AI|]  Hi Whereas you have Atrial Fibrillation then It's very likely that you must be on some ANTICOAGULANTS like WARFARIN. Have you checked your INR lately if not then get your PT/INR levels checked? To high INR levels could possibly be the reason of your blood from mouth. Another important advise is to consult personally a CARDIOLOGIST and a PULMONOLOGIST for detailed evaluation as the status of the ABLATED PULMONARY VEIN needs to be checked. I wish you good health and luck
