Management strategies for atrial fibrillation.

Atrial fibrillation is the most prevalent cardiac arrhythmia, affecting 10% of those aged over 80 years. Despite multiple treatment options, it remains an independent prognostic marker of mortality due to its association with clinical sequelae, particularly cerebrovascular events. Management can be broadly divided into treatment of the arrhythmia, via rhythm or rate control, and stroke thromboprophylaxis via anticoagulation. Traditional options for pharmacotherapy include negatively chronotropic drugs such as β-blockers, and/or arrhythmia-modifying drugs such as amiodarone. More recently, catheter ablation has emerged as a suitable alternative for selected patients. Additionally, there has been extensive research to assess the role of novel oral anticoagulants as alternatives to warfarin therapy. There is mounting evidence to suggest that they provide comparable efficacy, while being associated with lower bleeding complications. While these findings are promising, recent controversies have arisen with the...
