Is There Evidence for Anticoagulation in Atrial Fibrillation?

In 2018, the patients with subclinical atrial fibrillation lasting more than 24 hours or high risk stroke with shorter duration are treated with oral anticoagulants. I think right now the clinical practice is to lean towards anticoagulating as to not given that if there's a strong sense that AFib could be responsible for some arterial thromboembolism already. So you know, given that this is the best we have in terms of guideline, I would stick with that.
