CHA₂DS₂-VASc Score: Explanation and Clinical Context The CHA₂DS₂-VASc score is a clinical tool used to estimate the risk of stroke in patients with atrial fibrillation. It incorporates factors such as age, sex, and the presence of comorbid conditions like heart failure, hypertension, diabetes mellitus, and vascular disease. A higher score indicates a greater risk of stroke, guiding clinicians in decision-making regarding anticoagulation therapy.
