修正休克指数对急性非ST段抬高型心肌梗死预后的预测价值

摘要

目的:探讨修正休克指数(MSI)对急性非ST段抬高型心肌梗死(NSTEMI)患者预后的预测价值.方法:选取2013年1月至2016年1月承德医学院附属医院急诊科收治的急性NSTEMI患者462例,根据患者预后分为两组,存活出院组421例、院内死亡组41例,观察两组患者一般资料,心率、收缩压、修正休克指数等相关指标,统计并分析相关指标差异,以进一步评估MSI评估其预后的价值.结果:两组患者的一般资料以及心率,收缩压等指标相比没有统计学差异(P>0.05).存活出院组患者的MSI(0.842±0.267)显著低于院内死亡组患者相关指标(1.042±0.413),差异具有统计学意义(P<0.05).MSI>1.2的患者其死亡风险比为7.1,显著高于其他评价指标.结论:MSI对评估急性NSTEMI患者预后风险是简单、有效的预测指标.%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 pa-tients 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 ca-ses) . Heart rate, systolic blood pressure and modified shock index ( MSI) were recorded and analyzed. Re-sults: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.
