目的:探讨感染性腹泻患儿血清心肌酶CK-MB及心肌肌钙蛋白I检测的意义。方法:选择2003年11月～2004年12月吉林大学第四医院儿科20例感染性腹泻住院患儿进行血清心肌肌钙蛋白Ⅰ及心肌酶CK-MB检测。结果:12例心肌酶CK-MB有明显升高占60%,8例正常。心肌肌钙蛋白Ⅰ升高5例占25%,正常高限值2例,正常13例。结论:心肌酶CK-MB和心肌肌钙蛋白I升高均不同程度反映感染性腹泻患儿易合并心肌损伤。
Objective: To investigate the significance of serum CK-MB and cardiac troponin I in children with infectious diarrhea. Methods: Twenty patients hospitalized with infectious diarrhea in pediatric department of the Fourth Hospital of Jilin University from November 2003 to December 2004 were selected for serum cardiac troponin I and CK-MB. Results: CK-MB in 12 cases was significantly increased 60%, 8 cases were normal. Cardiac troponin Ⅰ increased in 5 cases accounted for 25%, 2 cases of normal high limit, normal in 13 cases. Conclusion: The increase of myocardial CK-MB and cardiac troponin I all reflect the complicated myocardial injury in children with infectious diarrhea to varying degrees.
