What is a CHA2DS2-VASc score?
The CHA2DS2-VASc score is a clinical based stroke risk score used to identify low stroke risk patients who should not be offered antithrombotic therapy to prevent stroke and reduce mortality. It is used for patients with Atrial Fibrillation (AF), including those with paroxysmal AF. Generally, low risk patients are those age less than 65 and lone AF, including those with a CHA2DS2-VASc score of 0 in males, or 1 in females.
