Why the study?
Knowledge about stroke risk in paroxysmal atrial fibrillation is limited, and most patients do not receive prophylactic anticoagulation despite guideline recommendations.
Is the risk of stroke different between patients with paroxysmal atrial fibrillation and those with permanent atrial fibrillation?
Is the risk of stroke different between patients with paroxysmal atrial fibrillation and those with permanent atrial fibrillation?
Ischaemic stroke risk is similar in paroxysmal and permanent atrial fibrillation, highlighting the need for appropriate anticoagulation in paroxysmal AF patients as per guidelines.

May support equating anticoagulation in PxAF with PermAF; leaves open this hypothesis pending randomized confirmation.**[[1]](https://pubmed.ncbi.nlm.nih.
