Comparison of the CHA2DS2-VASc, CHADS2, HAS-BLED, ORBIT and ATRIA Risk Scores in Predicting Non-Vitamin K Antagonist Oral Anticoagulants-Associated Bleeding in Patients with Atrial Fibrillation

The increasing adoption of non-vitamin K antagonist oral anticoagulants (NOACs) for stroke prevention in atrial fibrillation (AF) necessitates a reassessment of bleeding risk scores. Because known risk factors for bleeding are largely the same as for stroke, we hypothesize that stroke risk scores could also be used to identify patients with high bleeding risks. We aimed to compare the performance of two stroke risk scores (CHA2DS2-VASc and CHADS2) and three bleeding risk scores (HAS-BLED, ORBIT, and ATRIA) in predicting major and intracranial bleeding.
