Clinical efficacy of creatine phosphate sodium combined with ribavirin in treating infantile viral myocarditis and its effect on myocardial enzyme levels in children / 吉林大学学报(医学版)

ABSTRACT

Objective: To investigate the clinical efficacy of creatine phosphate sodium combined with ribavirin in the treatment of infantile viral myocarditis, and to elucidate its mechanism of the effects on myocardial enzyme levels in the children. Methods: A total of 96 children with viral myocarditis were selected; according to the random number grouping method, they were divided into observation group and control group (n=48). The myocardial enzymes and cardiac troponin I (cTnl) of the patients in two groups were detected, and anti-infection, supplementation of electrolytes, and nutritional support for myocardial treatment were performed; then intravenous infusion therapy of ribavirin was used. On this basis, the patients in observation group were given intravenous infusion of creatine phosphate sodium for 14 d. After treatment, the total effective rate of treatment of the patients in two groups, the levels of myocardial enzymes and cTnl and electrocardiogram were compared before and after treatment. Results: The total effective rate of the patients in observation group was 87. 50% (42/48), and it was 70. 83% (34/48) in control group; there was significant difference (X2 = 4. 04, P=0. 04). After treatment, the levels of lactate dehydrogenase (LDH), hydroxybutyrate dehydrogenase (HBDH), aspartate transaminase (AST), creatine phosphokinase (CPK), creatine kinase isoenzyme-MB (CK-MB) and CTnl of the patients in two groups after treatment were lower than before treatment (P<0. 05). The indicators mentioned above of patients in observation group were lower than those in control group (P < 0.05). The total improvement rate of electrocardiogram in the observation group (89.58%) was significantly higher than that in control group (72.92%), and the difference was statistically significant (X2 = 4. 38, P=0. 04). Conclusion: The total effective rate of creatine phosphate sodium combined with ribavirin in the treatment of infantile viral myocarditis is higher, and they can significantly reduce the levels of myocardial enzymes and improve the cardiac function; it is worth to apply in the clinical treatment.
