Anticoagulation Recommendation
No anticoagulation needed. Low stroke risk. Reassess periodically if risk factors develop.
No antithrombotic therapy needed. This patient is truly low-risk. Reassess if new risk factors develop (hypertension, diabetes, heart failure, vascular disease, or ageing into a higher bracket).
