CHA₂DS₂-VASc score - calculates stroke risk for patients with atrial fibrillation

Source: NCDR LAAO Registry

The CHA₂DS₂-VASc score is a widely used medical tool to guide physicians on blood thinning treatment in order to prevent stroke in patients with non-valvular atrial fibrillation.

Patients with atrial fibrillation are at increased risk of stroke due to blood clots that form in the left atrial appendage (LAA). Cleveland Clinic’s Atrial Fibrillation Stroke Prevention Center is staffed by specialists who have extensive experience in the use of devices to close off the LAA to reduce this risk.
