急性冠状动脉综合征病人血清sgp130与cTnI动态变化及意义

目的探讨急性冠状动脉综合征(ACS)病人血清可溶性糖蛋白130(sgp130)和肌钙蛋白I(cTnI)的变化及其临床意义。方法采用ELISA法检测34例急性心肌梗死(AMI)和33例不稳定型心绞痛(UA)病人发作时和缓解后血清sgp130和cTnI浓度的变化,并与36例健康查体者(对照组)进行比较。结果 UA病人发作时和缓解后、AMI病人胸痛发生后不同时间血清sgp130浓度明显降低,cTnI浓度明显升高,与对照组比较差异有显著性(F=13.084~75.459,q=3.092~21.404,P<0.05、0.01);UA病人发作时血清sgp130水平明显降低,cTnI浓度明显升高,与缓解后比较差异有显著性(F=13.084、49.854,q=5.168、5.348,P<0.01)。AMI病人胸痛发生后不同时间的血清sgp130、cTnI浓度之间比较,差异均有显著性(F=23.667、75.459,q=2.202~19.564,P<0.05、0.01)。AMI病人胸痛发生后24 h、3 d和7 d血清sgp130浓度变化与UA病人发作时和缓解后比较,差异有显著性(q=3.847~13.044,P<0.05、0.01),胸痛发生后24 h、3 d血清cTnI浓度与UA病人发作时和缓解后比较差异有显著性(F=75.459,q=2.938~22.622,P<0.05、0.01)。结论血清sgp130和cTnI浓度的动态变化对AMI早期诊断具有明显的价值,其变化程度可以作为炎症反应和病情严重程度的判断指标之一。

DYNAMIC CHANGES AND CLINICAL SIGNIFICANCE OF SOLUBLE GLYCOPROTEIN-130 AND CARDIAC TROPONIN I IN PATIENTS WITH ACUTE CORONARY SYNDROME

Objective To explore the dynamic changes and their clinical significance of serum cardiac troponin I(cTnI) and soluble glycoprotein-130(sgp130) in patients with acute coronary syndrome(ACS). Methods The serum cTnI and sgp130 of 34 patients with acute myocardial infarction(AMI) and 33 with unstable angina(UA) were determined by enzyme-linked immunosorbent assay(ELISA) at attack and at remission,36 healthy subjects served as controls. Results Compared with the controls,serum sgp130 levels were lower and cTnI ...
