The stroke risk calculator

An interactive resource that assists healthcare professionals to quickly assess the risk of stroke in patients with atrial fibrillation (AF).


The calculator helps to stratify patients according to stroke risk, based on the presence of various risk factors. Risk can be determined using either the CHADS2 index or the CHA2DS2-VASc index – an extension of the CHADS2 scoring system incorporating additional risk factors. A review of international guidelines for antithrombotic therapy in AF, which are based around stroke risk, is also included, along with directions to further reading in the form of supporting literature.
