Key result
CHA2DS2-VASc identifies truly low-risk patients but classifies more as high stroke risk than CHADS2.
Why the study?
Does the CHA2DS2-VASc scoring system improve thromboembolic stroke risk prediction compared to the CHADS2 scoring system in patients with atrial fibrillation?

This review provides an understanding of the CHA2DS2-VASc scoring system compared to CHADS2 for stroke risk stratification in atrial fibrillation to aid clinical decision-making.

May prompt bleeding risk scrutiny with CHA2DS2-VASc's broader high-risk labeling in AF; leaves open net benefit over CHADS2.
Odum et al. (2012) conducted a review in Atrial Fibrillation. CHA2DS2-VASc scoring system vs. CHADS2 scoring system was evaluated. The CHA2DS2-VASc scoring system identifies truly low-risk patients but classifies more patients as high risk for stroke compared to CHADS2, warranting careful evaluation of bleeding risks.
