The CHA₂DS₂-VASc Score for Atrial Fibrillation is an essential clinical tool designed to stratify the risk of stroke in patients diagnosed with non-valvular atrial fibrillation (AFib). This calculator assists healthcare professionals in evaluating individual patient risk based on specific clinical criteria. These include congestive heart failure, hypertension, age (≥75 years doubled, 65-74 years), diabetes mellitus, prior stroke/TIA/thromboembolism (doubled), vascular disease, and sex category (female). By quantifying this risk, the tool provides critical guidance for initiating and managing oral anticoagulation therapy, thereby preventing potentially devastating embolic events and optimizing patient outcomes.

Clinical Use: The CHA₂DS₂-VASc score is used to determine the stroke risk in patients with non-valvular atrial fibrillation and helps clinicians decide whether anticoagulation therapy is appropriate. Higher scores indicate higher risk.
