重症肺炎患儿心肌肌钙蛋白Ⅰ变化的意义

目的探讨心肌肌钙蛋白I(cTnI)在重症肺炎时的变化及其对心肌损害的诊断价值。方法应用Access全自动微粒子化学免疫分析仪,采用cTnI试剂盒检测47例重症肺炎急性期、25例恢复期血cTnI水平。结果33例急性期重症肺炎患儿血cTnI明显升高,异常率达70.2%,与非重症肺炎组比较有非常显著差异(P<0.01);恢复期11/25例升高,异常率44%,较急性期明显降低(P<0.05),cTnI与心肌损害程度呈显著正相关(r=0.63P<0.01)。结论重症肺炎患儿存在心肌损害,cTnI可作为早期监测心肌受损的指标。

Changes of Serum Troponin I in Children with Severe Pneumonia

Objective To investigate the changes of serum troponin I (cTnI) in children with severe pneumonia in the early time and its significance in the diagnosis of myocardial damage.Method cTnI was measured by automatic chemo-immuno-analyzer in 47 patients with severe pneumonia during acute stage and 25 patients during recovery stage.Results The levels cTnI in blood of 33 patients with severe pneumonia during the acute stage were obviously higher,with the abnormal rate 70.2%.There was a remarkable difference compared with control group(P<0.01).The levels cTnI in the 11 of 25 patients during recovery stage of severe pneumonia were higher(P<0.05),but much lower than those of acute stage.The change of cTnI was proportional to the extent of myocardial damage (r=0.63 P<0.01).Conclusions We can find the myocardial damage in children with severe pneumonia,cTnI can be used to detect the myocardial damage in the early stage of disease.
