“…Atrial fibrillation (AF) is a leading arrhythmia worldwide and the major risk of systemic thromboembolic events (Hindricks et al, 2021 ; January et al, 2019 ). Several predicting models, including CHA 2 DS 2 ‐VASc score (Hu & Lin, 2018 ; Zuo et al, 2013 ), C 2 HEST score (Li, Bisson, et al, 2019 ; Li, Pastori, et al, 2019 ; Lip et al, 2020 ), mCHEST score (Li, Bai, et al, 2021 ), HAT 2 CH 2 score (Emren et al, 2016 ; Hu & Lin, 2017 ), and HAVOC score (Ntaios et al, 2020 ; Zhao et al, 2019 ) have been elucidated for predicting new AF in different populations and all revealed acceptable discriminating power. A prospective study enrolled 528 symptomatic arrhythmic patients and showed a CHA 2 DS 2 ‐VASc score with a C statistic 0.63 and an optimal cutoff at 2 for new‐onset AF (Zuo et al, 2013 ).…”
