The C2HEST and mC2HEST scores to predict the risk of new onset atrial fibrillation after presentation with acute coronary syndrome.

We read with great interest the recent article by Flavio et al. [ [1] Biccire F.G. Tanzilli G. Prati F. Sammartini E. Gelfusa M. Celeski M. et al. Prediction of new onset atrial fibrillation in patients with acute coronary syndrome undergoing percutaneous coronary intervention using the C2HEST and mC2HEST scores: a report from the multicenter REALE-ACS registry. Int. J. Cardiol. 2023; 386: 45-49 Abstract Full Text Full Text PDF PubMed Scopus (0) Google Scholar ], which clarified the C2HEST scoring system to evaluate the development of new onset atrial fibrillation (NOAF) in patients with acute coronary syndrome after percutaneous coronary intervention. The risk of NOAF showed a gradual increase with C2HEST score. In addition to express our appreciation for the in-depth research, we would also like to raise a few comments.
