Implication

May warrant ethnicity-specific CHA2DS2-VASc thresholds in AF; hypothesis-generating for prospective validation before practice change.

Does the CHA2DS2-VASc score accurately stratify stroke risk in Asian patients with atrial fibrillation?

Population

5,855 oral anticoagulant-naive nonvalvular atrial fibrillation patients aged ≥20 years from the Korea National Health Insurance Service Sample cohort

Intervention

Risk stratification using the CHA2DS2-VASc score

Outcome

Ischemic stroke or composite thromboembolismhard clinical

The CHA2DS2-VASc score effectively identifies truly low-risk Asian patients with atrial fibrillation, validating its use in this population despite some differences in individual risk factor weights such as female sex.
