She has no major bleeding history and normal renal function. According to Australian recommendations on stroke prevention in atrial fibrillation, what is the most appropriate management regarding oral anticoagulation?

Accepted Answer

Commence a direct oral anticoagulant such as apixaban for long-term stroke prevention

Answer

Aspirin alone is sufficient for stroke prevention in atrial fibrillation

Answer

No antithrombotic therapy is required because she is in rate-controlled AF

Answer

Use dual antiplatelet therapy instead of anticoagulation

Oral anticoagulation should be avoided until she has had a documented transient ischaemic attack or stroke
