Abstract:
Objective To explore the changes of plasma angiotensinⅡ (AngⅡ) and cardiac function,and the curative effect of children with acute viral myocarditis (VMC) treated with captopril(CAP).Methods Concentrations of plasma AngⅡ were measured with radio-immunity and cardiac function was detected by Doppler echocardiography for the VMC group (n=60) before and after treatment [the CAP group (n=30), the routine group (n=30) and the control group (n=30)].Results 1. The level of plasma AngⅡ significantly increased and the contractive and diastolic function obviously declined in children with acute VMC. There was a significant difference between VMC group and control group, with a significant correlation between the level of AngⅡand the contractive diastolic function.2. Compared with the level before treatment, the level of AngⅡ decreased and the contractive function obviously ameliorated in two groups; the diastolic function obviously ameliorated in the CAP group and did not ameliorate in the routine group after treatment. In CAP group the level of AngⅡ and the cardiac function significantly improved; there were statistical differences between the two groups after treatment.Conclusions 1.The increase of the plasma AngⅡ was an important factor for decrements of the contractive and diastolic function in acute viral myocarditis.2.It could decrease the concentration of plasma AngⅡ and ameliorate cardiac function in children with acute VMC treated with captopril,which was an effective therapy for acute VMC.
