The CHA2DS2-VAScscore calculates the stroke risk for patients with atrial fibrillation, possibly better than the CHADS2 score. The confusion within this component of the CHA2DS2-VASc score comes from the inclusion of TE. The CHADS2-VASc system, with having three more potential variables, inevitably classifies more patients into a high-risk group.
