To identify patients who are at risk of stroke when they have atrial fibrillation, we use a scoring system called the CHA2DS2-VASc scoring system.
What is the CHA2DS2VASc score?
The CHA2DS2–VASc score is a clinical prediction rule for estimating the risk of stroke in patients with atrial fibrillation (AF), a common and serious heart arrhythmia associated with stroke. AF can cause blood to stagnate in the upper heart chambers, leading to the formation of a clot. When clots form here they can dislodge, travel through the heart and circulation to the brain, where they result in a stroke. You can use the table below to determine your risk factor for stroke.
