    Atrial fibrillation usually requires ongoing follow-up, even when symptoms improve.

    Routine visits may review heart rate, rhythm, blood pressure, symptoms, stroke risk, bleeding concerns, and treatment goals.

The article also says

People taking warfarin need regular blood tests called INR tests to make sure its effect remains in the intended range.

Direct-acting anticoagulants do not require INR testing, but kidney function, blood count, and medication interactions still need periodic review.

Tell clinicians and dentists about anticoagulant use before procedures.

Check before starting nonprescription pain relievers, supplements, or new medicines because some can increase bleeding or affect heart rhythm.

Do not change or skip heart or anticoagulant medicines without guidance.

Every sign above is quoted from the sofidex article on Atrial fibrillation. If you are not sure, err upward — it is always reasonable to be checked.
