Comparative validation of HAS‐BLED, GARFIELD‐AF and ORBIT bleeding risk scores in Asian people with atrial fibrillation treated with oral anticoagulant: A report from the COOL‐AF registry

The clinical utility for bleeding prediction of GARFIELD-AF, HAS-BLED, modified HAS-BLED and ORBIT scores were similar in anticoagulated Asian patients with AF participating in the COOL-AF registry. We found no advantage of the ORBIT over HAS-BLED score for bleeding risk prediction, even in direct oral anticoagulant users.
