It has been found that monitoring the dynamics of myocardial enzymes and cardiac troponin T (cTnT) has high values in evaluating the severity of severe pneumonia in children.9,10 In this study, the values of detection of myocardial enzymes, cTnT and hepatic and renal function in the treatment of severe pneumonia in children were analyzed. The gene discussed is TNNT2; the disease is susceptibility to pneumonia measurement.
