What are the steps to decide which OAC to use for stroke prevention?
Step 1: Identify low-risk patients using CHA2DS2-VASc score. Step 2: Address modifiable bleeding risk factors and flag up patients with a HAS-BLED score of 3 for regular review and follow-up. Step 3: Begin NOAC (or VKA with high time in therapeutic range) as first line therapy for OAC.
