What is the CHA2DS2-VASc score?
The CHA2DS2-VASc score is a risk score used to assess stroke risk in patients with atrial fibrillation (AF). It takes into account factors such as sex, age, medical history, treatment, tobacco use, and race. A score of 0 in males and 1 in females indicates a low risk of stroke, and patients with a score of 1 or higher are candidates for stroke prevention with oral anticoagulation.
