CHADS2 Score for Atrial Fibrillation Stroke Risk

Estimates stroke risk in patients with atrial fibrillation by the CHADS2 criteria.

The formula is additive, with the points next to the "Yes" of each corresponding question.

A newer risk score to determine stroke risk in atrial fibrillation patients called CHA2DS2-VASc may provide a more accurate risk assessment.
