This calculator uses the CHA2DS2-VASc risk factors to help you visualize your potential risk for AFib-related stroke by giving you a numbered score. The CHA2DS2-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.

My CHA2DS2-VASc score
Your score indicates that your potential risk level for having an AFib-related stroke is low. People with a score of 0 are not typically prescribed blood thinners.
You should always discuss your specific situation with your healthcare professional. Only they can tell you whether you should be taking a blood thinner to reduce your risk of AFib-related stroke.
Feel free to bring this with you to your next appointment to start a conversation about your stroke risk and what you can do to help reduce it.
