Abstract Background: Early identification of high-risk patients presenting with ST-segment elevation myocardial infarction (STEMI) helps prevent complications. The shock index (SI) is a bedside risk-stratification tool used in emergency departments. In this study, we aimed to assess the SI’s predictive value for prognosticating in-hospital and one-year mortality, as well major cardiovascular events (MACEs). As secondary endpoints, assessed age performance influence prehospital transport factors on value. Methods: This prospective cohort study named SEMI-CI enrolled STEMI who were referred cardiology hospital Isfahan. We analyzed data 867 STEMI. Systolic blood pressure (SBP) heart rate (HR) upon admission calculate SI. Patients divided into two groups based SI, 277 had SI > 0.7. Results: In-hospital death, MACE more prevalent those ≥ However, after multivariate adjustment, was an independent predictor mortality MACE, but it not associated mortality. Furthermore, rates increased from lower higher groups. Among transferred by medical services our hospital, showed prognostic implications Conclusions: current that positive are valuable tools identify
