Establishment and validation of a machine learning-based predictive model for in-hospital mortality risk in acute myocardial infarction patients complicated with diabetes mellitus
Clinical Report: Machine Learning Model for In-Hospital Mortality in AMI with DM
Overview
This study developed and validated a machine learning model to predict in-hospital mortality risk in acute myocardial infarction patients with diabetes mellitus complications. The XGBoost model demonstrated the highest predictive performance, offering a valuable tool for identifying high-risk patients.
Background
Acute myocardial infarction (AMI) is a leading cause of mortality globally, particularly among patients with diabetes mellitus (DM), who face significantly higher mortality rates. The coexistence of these conditions presents a dual burden on healthcare systems, necessitating improved risk stratification strategies to enhance patient outcomes. Machine learning models may provide innovative solutions to predict mortality risk and guide clinical interventions.

Key Findings
The study identified seven key predictors of in-hospital mortality in AMI patients with DM.
The XGBoost model outperformed other machine learning algorithms in predictive accuracy.
SHAP analysis enhanced the interpretability of the predictive model.
In-hospital mortality rates for AMI patients with DM are significantly higher compared to non-diabetic patients.
The model can assist in early intervention strategies for high-risk patients.
Clinical Implications
Healthcare providers can utilize this machine learning model to identify AMI patients with DM who are at high risk for in-hospital mortality. Early identification may facilitate timely interventions, potentially improving patient outcomes and reducing mortality rates.
Conclusion
The development of an interpretable machine learning model for predicting in-hospital mortality in AMI patients with DM represents a significant advancement in risk stratification. This model can serve as a valuable tool in clinical settings to enhance patient care.
