Abstract:
Objective To study the dynamic variation of mbisoenzyme of creatine kinase(CK-MB) in the infected course of respiratory syncytial virus and explore the value of CK-MB/CK in the diagnosis of myocardial damage.Methods A total of 577 pediatric patients (317 males,260 females,aged 2 ～ 18 months) with CK-MB/CK ＞5％ from 2010 to 2013 were enrolled in this study (44 complicated by myocardial damage).Five hundred and thirty-three patients with high values CK-MB simply were randomly divided into treatment group (n =243) and control group(n =290).The dynamic variation of CK-MB were investigated.The diagnosis analyzed by receiver operating characteristic (ROC)curve was used to explore the predictive value of differential diagnosis between the pediatric patients with myocardial damage and without myocardial damage.Results Approximately 46.5％ of cases with rotavirus diarrhea had higher CK-MB and 3.5％ of cases had myocardial damage.The time of CK-MB achieved peak and anomalous duration was different between the cases with myocardial damage and without myocardial damage.There was no statistical significance between the cases with or without protecting myocardial(P ＞ 0.05).The ROC curves were constructed with area under the ROC curves of 0.663 (95 ％ CI 0.578,0.747).Conclusion The blood levels of CK-MB in children with respiratory syncytial virus infection existed obvious dynamic variety,which contributed little value to the diagnosis of myocardial damage.
