【摘要】 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。更多还原

【Abstract】 Objective To study the value of high-sensitivity troponin I in risk stratification of acute coronary syndrome.Methods 90cases of patients with acute coronary syndrome were as the objects of study,and were divided into UAP group for unstable angina,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 troponin 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.更多还原
