Five supervised machine learning classifiers, including XGBoost, logistic regression, KNN, LightGBM, AdaBoost, were used in building the MACE prediction model.Results: 1293 patients were finally included in this study, with MACE occurred in 279 (21.6%) participants. After sample balancing using the SMOTE method, non-parametric tests revealed significant differences in imaging indicators, some myocardial injury markers, and tongue image parameters between the 2 groups of patients:LDH,MYO,TC_ROOT_R,TC_ROOT_G (P< 0.05); the XGBoost, LightGBM models had the highest predictive power (The AUC values of the verification set > 0.97); the combination of SHAP values revealed the importance of the features and provided a quantitative metric to assess the contribution of each feature to the prediction results, Finally, subgroup analysis was conducted based on specific events of MACE.Conclusion: This study provides insight into the potential application of myocardial injury markers, tongue colour parameters, in the prediction of MACE, and future studies could extend the optimisation of the prediction model and explore its application in other cardiovascular diseases.Keywords: machine learning, coronary heart disease, major adverse cardiovascular events, markers of myocardial injury, tongue image, prediction models |
