Prediction of New-onset Atrial Fibrillation for General Population in Asia: A Comparison of C2HEST and HATCH Scores

Purpose: To explore the use of the C2HEST and HATCH scores to predict the incidence of atrial fibrillation (AF) in Asians.

Method: The predictive capability of AF of C2HEST and HATCH scores was estimated by area under the receiver operating characteristic curve (AUROC). DeLong test was used to compared the difference of AUROC between the 2 scores.

Result: A total of 692,691 subjects were investigated. The risk of AF increased with increasing C2HEST and HATCH scores (p for trend<0.001). The AUROC for C2HEST and HATCHs in predicting AF occurrence was 0.7895 and 0.7711, respectively. C2HEST score had a significant better capability for AF stratification than HATCH score (DeLong test <0.001).

Conclusion: Higher C2HEST and HATCH scores were more strongly associated with the incidence of AF. The C2HEST score appeared to be more predictive of AF than the HATCH score.
