目的：研究超敏肌钙蛋白I在急性冠状动脉综合征危险分层中的应用价值。方法选择急性冠状动脉综合征患者90例作为研究对象，分为不稳定型心绞痛（UAP）组、无 ST 段抬高的急性心肌梗死（NSTEMI）组和 ST 段抬高的急性心肌梗死（STEMI）组，检测超敏肌钙蛋白I水平及心功能指标。结果超敏肌钙蛋白I水平呈现UAP 组＜NSTEMI组＜STEMI组（P＜0．05），且与E峰、E/A值、LVEF、LVEDD呈负相关（P＜0．05）。结论超敏肌钙蛋白I的水平与急性冠状动脉综合征的危险分层有相关性，其含量越高，疾病的危险分层越严重。

Objective To study the value of high-sensitivity troponin I in risk stratification of acute coronary syndrome.Methods90 cases of patients with acute coronary syndrome were as the objects of study,and were divided into UAP group for unstable an-gina,NSTEMI group for non-ST-segment elevation acute myocardial infarction,and STEMI group for ST-segment elevation acute myocardial infarction.High-sensitivity troponin protein I levels and cardiac function were detected.Results High-sensitivity tropo-nin I levels in UAP group was lower than that in the NSTEMI group,and lower than that in the STEMI group(P<0.05),and the peak E,E/A values,LVEF,LVEDD were negatively correlated(P<0.05).Conclusion There is hierarchical correlation between high-sensitivity troponin I levels and the risk of acute coronary syndrome.The higher the content,the more serious for disease risk stratification.
