Wow catmom777; no more wine? no more coffee? I suspect if you search enough you should find just as many studies calling that BS!
Of course we are all individuals with individual metabolisms. So there are likely people who cafein or alcohol will effect in a negative way and maybe cause more AFIB. Just like some people I know who drank 2 CASES of beer EVERYDAY for 40 years and NEVER had any liver problems! Different stroke for different folks
Personally I went thru this same phase you are at now, after my valve replacement and being put on blood thinners. I researched it – why bother if I cannot have my beloved beer? Well, MY research showed that alcohol is NOT a big bad thing. I asked my cardiologist and on two different visits his various super nurses: ALL said no problem to alcohol. I said what about 3-4 beers a day? Answer: no problem. Based on my experience now since Nov. 2018 open heart surgery, they are correct.
