摘　　要：目的探讨急性心肌梗死(AMI)患者血清心肌肌钙蛋白I(cTnI)峰值水平与预后的关系。方法回顾性分析。182例AMI患者,根据cTnI峰值水平分为A组72例(cTnI≥5μg/L)和B组110例(cTnI<5μg/L)两组,比较cTnI峰值水平与心力衰竭、心源性死亡的发生率、左心室射血分数(LVEF)关系。结果住院期间A组和B组发生心力衰竭分别为42.7%、27.3%,心源性死亡发生率分别为19.4%、3.6%,LVEF分别为(45±12)%、(56±13)%,差异均有显著性。结论选定一个恰当的血清cTnI切入点,对AMI患者住院期间预后的评估更有价值。Objective To investigate the relationship between eardiac troponinl（cTnI） and the prognosis of acute myocardial infarction（AMI）. Methods Top value of serum eTnI in 182 patients with AMI was analyzed retrospectively. According to top value of serum cTnI , all patients were divided into two groups. among whom 72 were assigaed to group A （cTnI≥5μg/L） and 110 to group B （cTnI 〈 5μg/L）. Relationship of eTnI level and heart failure , rate of cardiac death, left ventricle ejection fraction（LVEF） were accessed. Results During hospitalization, heart failure of group A and group B were 42.7% ,27.3%. Rate of cardiac death of group A and group B were 19.4% ,3.6%. Left ventriele ejection fraction（LVEF） of group A and group B were （45% ± 12）%,（56% ± 13）%, respectively .There were significant difference between the two groups. Conclusion A proper level of cTnI has its signifieanee in evaluating the prognosis of acute myocardial infarction（ AMI）.
