1
Atrial fibrillation (AF) significantly increases the risk of ischemic stroke, with oral anticoagulation (OAC) reducing this risk by 60%-70%.
-
2
Continuous rhythm monitoring has revealed a spectrum of atrial arrhythmias, challenging the traditional binary AF diagnosis and treatment approach.
-
3
AF burden, defined as the proportion of monitored time spent in AF, is associated with higher risks of ischemic stroke and systemic embolism.
-
4
Low AF burden patients generally experience low absolute event rates, raising questions about the net clinical benefit of OAC in this group.
-
5
Current evidence suggests that AF burden alone is insufficient for anticoagulation decisions, as it interacts with thromboembolic and bleeding risks.
