Performance and Validation of a Novel Biomarker-Based Stroke Risk Score for Atrial Fibrillation

Background: Atrial fibrillation is associated with increased but variable risk of stroke. Our aim was to validate the recently developed biomarker-based ABC (age, biomarkers [high-sensitivity troponin and N-terminal fragment B-type natriuretic peptide], and clinical history of prior stroke/transient ischemic attack)-stroke risk score and compare its performance with the CHA 2 DS 2 VASc and ATRIA (Anticoagulation and Risk Factors in Atrial...
