CHA₂DS₂-VASc Score and Stroke Prediction in Atrial Fibrillation in Whites, Blacks, and Hispanics.

ABSTRACT: Background and Purpose- Despite modest predictive ability for ischemic stroke (IS), the CHA₂DS₂-VASc score is widely used for stroke prediction in atrial fibrillation. Among patients with atrial fibrillation, we aimed to (1) compare the IS or transient ischemic attack (TIA) incidence by CHA₂DS₂-VASc in blacks and Hispanics versus whites; (2) compare predictive ability of CHA₂DS₂-VASc score for IS or TIA in blacks and Hispanics versus whites; and (3) determine improvement in predictive ability of CHA₂DS₂-VASc score from addition of race/ethnicity. Methods- Using data from Optum Clinformatics, a large administrative claims database, we analyzed patients with atrial fibrillation enrolled in commercial and
