Correct answer: E — Start a direct oral anticoagulant after renal and interaction checks

The best answer is “Start a direct oral anticoagulant after renal and interaction checks”. This patient’s age, hypertension and diabetes support oral anticoagulation for non-valvular atrial fibrillation; a direct oral anticoagulant is generally preferred when suitable. Aspirin or clopidogrel alone does not provide equivalent stroke prevention. Cardioversion planning does not remove the need to assess anticoagulation and embolic risk.
