Abstract：Objective: To investigate the value of modified shock index in evaluation of the prognosis of patients with acute non-ST-segment elevation myocardial infarction (NSTEMI). Methods: 462 cases of patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) were recruited in this study in affiliated hospital of Chengde medical college from January 2013 to January 2016. All 462 cases were divided into 2 groups depend on the final prognosis: survival group (421 cases) and in-hospital death group (41 cases). Heart rate, systolic blood pressure and modified shock index (MSI) were recorded and analyzed. Results: There was no significant difference between the two groups on age, gender, chronic disease history and family disease history (P>0.05). The MSI in the group of death (1.042±0.413) were significantly higher than the group of survival (0.842±0.267) (P<0.05). The risk of death was elevated in the group with "MSI>1.2", which odds ratio (7.1) higher than the other evaluated index. Conclusion: MSI in emergency department are simple and effective predictor for short-term outcomes in patients with NSTEMI.
