Diagnostic Value of Detection of Serum CK-MB and Cardiac Troponin I for Children with Viral Myocarditis

Objective To study the diagnostic value of serum CK-MB (CK-MB) and cardiac troponin Ⅰ (cTnI) for children with viral myocarditis. Methods 39 cases of children with viral myocarditis were selected as the observation group, 39 cases of healthy children received routine physical examination over the same period were selected as control group. The detection results of cTnI, CK-MB of two sets were compared, and the positive rate of cTnI and CK-MB was contrasted in observation group. Results cTnI and CK-MB of observation group was significantly different with control group when children was with onset 1 ～ 2 d;There were significant differences of cTnI of observation group when incidence 7 d and 14 d with control group. The positive detection rate of observation group incidence of 1 ～ 2 d cTnI was significantly higher than CK-MB; The detected positive rate of 7 d and 14 d when cTnI was significantly higher than CK-MB. Conclusions The cTnI has high specificity and sensitivity in the diagnosis of viral myocarditis.
