Ischemic stroke (IS) approximately accounts for 80% of strokes in elderly patients, which has become the second most serious cause of death in the world (Some models have also been developed to predict in-hospital mortality in cases of acute ischemic stroke. Mittal and Goel (However, these models were not applicable to the elderly population in the ICU, and the performance of the model predicting the mortality among the elderly admitted to the ICU was unknown. The elderly patients should be given more attention because the majority of ischemic stroke cases occur in these elderly patients, while young patients who suffer from IS have a low mortality rate. In addition, with prolonged life expectancy, the aging population experiences a significant increase in stroke incidence. Additionally, elderly patients exhibit physiological changes including neuronal plasticity and decreased repair ability, as well as changes in the structure of the vascular system and complications, which increase the complexity of prediction. Limited data regarding short-term mortality predictors for elderly patients with IS are available. A model based on the LR method was constructed with 469 older patients (Several factors were found to be associated with the increased short-term mortality, including age (In this study, we aimed to develop prediction models for 28-day in-hospital mortality in elderly patients with IS using ML algorithms. The model was based on variables collected at admission. This will improve clinical decision-making and healthcare quality through early risk stratification after acute IS in elderly patients.
