  •   Objective  To establish a predictive model of new onset atrial fibrillation in patients with acute coronary syndrome (ACS) during admission, so as to provide scientific basis for early detection of high-risk patients and timely intervention measures.  Methods  A retrospective cohort study was conducted among 1 915 patients with ACS who were admitted to the Department of Cardiology of a large general hospital between January 2010 and December 2019. Patients were randomly divided into two groups: model group and validation group. In the model group, a multivariate Logistic regression analysis model was used to screen the independent factors associated with new onset atrial fibrillation. Regression prediction model and nomogram were established, and validated in the validation group. Area under curve (AUC) of receiver operating characteristic curve (ROC) and Hosmer-lemoshow test were used to evaluate the discrimination and calibration of the model, respectively.  Results  There were 958 cases in the model group comprising 62 new onset atrial fibrillation cases, and 957 cases in the validation group comprising 65 new onset atrial fibrillation cases. In the model group, seven indicators were independently associated with atrial fibrillation, including age, heart rate at admission, Killip classification of heart failure, N-terminal pro-brain natriuretic peptide (NT-proBNP) level, left atrial diameter, right atrial diameter and neutrophil count. In the modeling group, the AUC was 0.91 (95% CI: 0.88-0.94) in model group and 0.86 (95% CI: 0.81-0.91) in validation group. Calibration plot and goodness of fit test (in modeling group and validation group, P>0.05) indicated that the prediction model had a good calibration ability.  Conclusions  In this study, the prediction model of new onset atrial fibrillation in patients with acute coronary syndrome was successfully constructed, which has a good discrimination and calibration, the nomogram could conveniently be used and intuitively predict the risk of atrial fibrillation, thus provides foundation for early intervention and improvement of prognosis in clinical practice.
