What is the recommended approach for assessing stroke risk in patients with atrial fibrillation (AF)?
We recommend use of the CHA2DS2-VASc as a simple clinical based stroke risk score to initially identify low stroke risk patients. Low risk patients are generally those age < 65 and lone AF irrespective of sex (this includes those with a CHA2DS2-VASc score 0 in males, or 1 in females).
