Comparative Performance of ATRIA, CHADS(2), and CHA(2)DS(2)-VASc Risk Scores Predicting Stroke in Patients With Atrial Fibrillation Results From a National Primary Care Database

摘要

BACKGROUND Previous studies report that CHADS(2) and CHA(2)DS(2)-VASc risk scores have similar discriminating ability (C statistic similar to 0.6). Recently a clinically based risk score, the ATRIA (Anticoagulation and Risk Factors in Atrial Fibrillation) study risk score, was developed and validated.
