The HELT-E2S2 score predicted ischemic stroke with a C-statistic of 0.681, which was significantly higher than the CHADS2 (0.647) and CHA2DS2-VASc (0.641) scores in Japanese patients with non-valvular atrial fibrillation.

Does a novel risk stratification system improve prediction of ischemic stroke in Japanese patients with non-valvular atrial fibrillation?
A novel risk score may be useful for identifying Japanese NVAF patients at risk of ischemic stroke.
Effect estimate: C-statistic 0.681 (95% CI 0.647-0.714)
Absolute Event Rate: 0.681% vs 0.647%
p-value: p=0.027
BACKGROUND: Recently, identification of independent risk factors for ischemic stroke in Japanese non-valvular atrial fibrillation (NVAF) patients was made by analyzing the 5 major Japanese registries: J-RHYTHM Registry, Fushimi AF Registry, Shinken Database, Keio interhospital Cardiovascular Studies, and the Hokuriku-Plus AF Registry. METHODS AND RESULTS: -VASc scores (0.641; 95% CI=0.608-0.673, P=0.008). CONCLUSIONS: score may be useful for identifying Japanese NVAF patients at risk of ischemic stroke.
Okumura et al. (Wed,) conducted a cohort in Non-valvular atrial fibrillation (NVAF) (n=12,289). HELT-E2S2 score vs. CHADS2 and CHA2DS2-VASc scores was evaluated on Predictive value for ischemic stroke (C-statistic) (C-statistic 0.681, 95% CI 0.647-0.714, p=0.027). The HELT-E2S2 score predicted ischemic stroke with a C-statistic of 0.681, which was significantly higher than the CHADS2 (0.647) and CHA2DS2-VASc (0.641) scores in Japanese patients with non-valvular atrial fibrillation.
