If you know you are entirely free of arrhythmia, particularly AF, I would suggest discussing going off a DOAC with your cardiologist, especially if he/she agrees that youre CHA2DS2-VASc score is under 2.0. The rationale to continue the DOAC is not erroneous, especially as we age and become more sedentary, with more sitting for example, but also if you heart has the odd short run of AF. I saw a paper not too long ago that short runs of paroxysmal AF are not as worrying, or risky, as those that go several hours or for a day or more before they convert.
