Nowhere near enough information.
Who and when was atrial fibrillation diagnosed?
What is the cause of your AF?
What drugs are you taking?
How old are you?
You are not going to get a meaningful answer to your brief question on AB, but as a general answer...a very general answer ....in my opinion it is off limits or just one small glass of wine daily.
I had a small stroke last November. No damage done but tests showed AF. I was prescribed Apixaban 5mg (twice a day). Which is excellent. My GP said I am less likely than any other person my age to have another stroke.
