CHA2DS2-VASc Recalibration with an Additional Age Category (50-64 years) Enhances Stroke Risk Stratification in Chinese Atrial Fibrillation Patients

CONCLUSION Chinese patients with AF and low CHA2DS2-VASc score were at a disproportionally high risk of ischemic stroke. Chinese patients between 50-64 are at a high risk for stroke despite a low CHA2DS2-VASc score and have low bleeding risk. Only patients aged <50 years are truly low risk. Teaser Chinese atrial fibrillation (AF) patients with low CHA2DS2-VASc scores had a higher ischemic stroke risk than the Caucasians’ counterparts. In this study, we identified that even for Chinese AF patients aged 50-64 years, stroke risk is still markedly elevated. Only patients aged <50 belong to the truly low risk group.
