Machine learning-based mortality risk prediction model for elderly diabetic patients with non-ST-segment elevation myocardial infarction using MIMIC-IV database

Non-ST-elevation myocardial infarction (NSTEMI) in elderly diabetic patients presents unique challenges in risk assessment and prognosis prediction. This study aimed to develop and validate a machine learning-based mortality risk prediction model for this specific population using the MIMIC-IV database. We conducted a retrospective cohort study including 5,272 NSTEMI patients aged ≥ 55 years with diabetes from the MIMIC-IV database. Multiple machine learning models were developed using clinical...
