Changes of Serum Cardiac Muscle Enzymogram and Heart Function before and after Interventional Therapy in Ventricular Septal Defect Patients and Its Clinical Significance / 实用儿科临床杂志

ABSTRACT

Objective To explore the changes of cardiac muscle enzymogram and heart function before and after transactheter closure of ventricular septal defect(VSD).Methods The serum levels of cardiac troponin(cTnI),carcatine kinase(CK),lactie dehydrogenase(LDH),aspartate aminotransferase(AST)and the left ventricular ejection fraction(LVEF)were detected by two-dimensional echocardiography,and the change before and after intervention was analyzed.Results The serum level of cTnI in VSD patients after treatment was markedly higher than that before intervention[(0.29?0.17)?g/L vs(0.02?0.01)?g/L,t=9.0 P0.05).Conclusion Catheterization to treat VSD may have influence on enzymogram and the heart function,which may be related to the minor myocardial damage during the operation.
