What is the CHA2DS2-VASc score?
The CHA2DS2-VASc score is a risk score that is used to calculate the risk of stroke in patients with atrial fibrillation. It assigns points for each of the following risk factors: Sex (female), Age (< 60 years), Medical History (hypertension, diabetes mellitus, coronary artery disease/myocardial infarction, peripheral arterial disease, congestive heart failure, previous stroke, pulmonary disease, and hepatic or renal disease), Treatment (interacting drugs [eg, amiodarone]), Tobacco Use (within 2 years), and Race (non-white). The maximum score is 8, and patients who are low risk (a score of 0 in males, 1 in females) do not require antithrombotic treatment. All AF patients with at least 1 stroke risk factor are candidates for stroke prevention with oral anticoagulation. In addition, the score can be used to assess the bleeding risk of patients.
