The Detection of Myoglobin,Cardliac Troponin-I and Creatine Kinase-MB in Children with Mycoplasmal Pneumonia

Objective To detect and compare the change of level of myoglobin(Mb),cardliac troponin I(cTn-I) and creatine kinase-MB(CK-MB) in children with acute mycoplasmal pneumonia combine with injury of cardiac muscle,in order to discuss the signifance in the diagnosis of disease.Methods The content of Mb、cTn-I and CK-MB in serum were measured and the change were compared in 55 cases MPP combined with injury of cardiac muscle,during acute and recovery phase,and 55 normal children were served as control group.Results The value of Mb、cTn-I and CK-MB in MPP combined with injury of cardiac muscle group were sighificantlly higher than in control group in the serum of acute phase(P0.01).And the content of Mb、cTn-I and CK-MB were descended in recovery phase and were significant lower than that of acute phase,but still higher than the control group(P0.05),in MPP combined with injury of cardiac muscle group(P0.01).Conclusion Children with mycoplasmal pneumonia may combine myocardial injures,and Mb、cTn-I and CK-MB are sensitive parameters to diagnose the injure of cardiac muscle.
