Atrial Fibrillation and Stroke Prevention – What's New?

In this episode of Voice of Stroke, we explore the latest evidence shaping stroke prevention in atrial fibrillation (AF) – a condition responsible for up to a quarter of all ischaemic strokes. This episode examines emerging strategies and unresolved questions in AF management, including: Whether left atrial appendage closure (LAAC) can replace anticoagulation in patients eligible for oral therapy The role of catheter ablation in reducing recurrent stroke risk after AF-related stroke New population data on blood pressure control and stroke risk, particularly in younger AF patients Key insights: Anticoagulation remains the cornerstone of stroke prevention, but limitations persist LAAC may reduce bleeding risk but does not yet clearly outperform anticoagulation in eligible patients Catheter ablation did not reduce recurrent stroke risk in current trial evidence Blood pressure is a critical—and potentially under-recognised—driver of stroke risk in AF, especially in younger populations Together, these findings refine how we approach AF stroke prevention, balancing procedural interventions, pharmacological therapy, and risk factor management.
