What scores are used to initially identify low risk patients with atrial fibrillation?
The CHA2DS2-VASc score is used to initially identify low risk patients with atrial fibrillation. This score is better than the CHADS2, Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA), and CHADS2 score plus age 65-74 years, used in Canadian guidelines (CHADS65) in identifying low risk patients. This score is easier to calculate and the default should be stroke prevention for all AF patients unless deemed to be low risk.
