Introduction

Secondary stroke prevention remains a cornerstone of long-term care following ischemic stroke, yet balancing efficacy and safety—particularly the risk of bleeding—continues to challenge clinicians worldwide. Factor XIa inhibitors represent an emerging therapeutic class with the potential to transform antithrombotic strategies by reducing thrombotic risk while minimizing bleeding complications.

To support healthcare professionals in translating evolving evidence into clinical practice, the World Stroke Academy has developed an educational infographic titled “Factor XIa Inhibitors: A New Paradigm in Secondary Stroke Prevention.” The infographic offers a clear, visual synthesis of the scientific rationale, clinical evidence, and potential role of Factor XIa inhibition in stroke prevention.

Key educational themes

The unmet need in secondary stroke prevention, including the limitations of current antithrombotic therapies and the ongoing challenge of balancing ischemic protection with bleeding risk

The biological rationale for targeting Factor XIa within the coagulation cascade, highlighting its role in thrombosis with a potentially lesser impact on hemostasis

Emerging clinical evidence on Factor XIa inhibitors, including findings from recent trials evaluating efficacy and safety in stroke and cardiovascular populations

The potential clinical positioning of Factor XIa inhibitors in secondary stroke prevention, including their role in patients at high bleeding risk or those unsuitable for conventional therapies

Considerations for future integration into practice, including ongoing research, patient selection, and alignment with evolving stroke prevention strategies

By distilling complex scientific and clinical developments into an accessible format, the infographic aims to enhance understanding of this novel therapeutic approach and support informed decision-making. This educational resource complements existing stroke prevention frameworks while highlighting the promise of safer, more targeted anticoagulation strategies.
