This calculator uses the CHA 2 DS 2 -VASc risk factors to help you visualize your potential risk for AFib-related stroke by giving you a numbered score. The CHA 2 DS 2 -VASc score is widely used by doctors to evaluate stroke risk in people with AFib and help guide treatment recommendations.

It may feel daunting, but knowing your score can help you make a plan with your doctor to help keep you protected. Using this tool may also help you understand how your stroke risk can change over time—people with low scores right now may need to reevaluate their scores periodically as they age or develop other health conditions. This tool does not replace the risk assessment you need to complete with your doctor.

The information you input in the stroke risk calculator will not be collected, stored, used, or transferred.
