Pharmacotherapy for stroke prevention in nonvalvular atrial fibrillation: current strategies and future directions.
Expert Opinion on Pharmacotherapy 2022 December
INTRODUCTION: Cardioembolic stroke, associated to nonvalvular atrial fibrillation (NVAF), accounts for approximately one in every four strokes. Cardioembolic stroke has a bad prognosis and is associated with a significant rate of recurrence.
AREAS COVERED: This article reviews current pharmacotherapeutic options for prevention of stroke in NVAF, paying special attention to their use in particular clinical settings (e.g. cardioversion, catheter ablation). We also aim to review new drug candidates that have entered clinical studies in this indication.
EXPERT OPINION: Oral anticoagulant therapy (OAT) remains the mainstay for ischemic stroke prophylaxis in NVAF in patients at risk. Several oral (asundexian, milvexian) and parenteral (abelacimab, osocimab, xisomab, IONIS-FXIRX , fesomersen) factor XIa inhibitors are under development. These new compounds appear to be associated with a low bleeding tendency and have the potential to complement current existing alternatives for anticoagulation. However, it is also of paramount importance to implement interventions to improve adherence to available anticoagulants, which is currently suboptimal. Non-anticoagulant drugs, such as colchicine, metformin and dronedarone, also being investigated to reduce the burden of NVAF and cardioembolic stroke. Additional clinical data are needed to more clearly define the role of these drugs for stroke prevention in NVAF.
