I have chronical non stop AF (blessed with no feeling of it). For blood thinners I take only Nattokinase (1 at every 6 hours) - if I don't take it, I have very difficult time with breathing. Taking also Magnesium, Hawthorne and Arjuna (top Ayurveda herb for heart problems).
Also take first thing in the morning Cardio Chelate. Good luck!
