The effects of L-carnitine on abnormal myocardial enzymes of HFMD / 实用医学杂志

ABSTRACT

Objective To observe the clinical effects of L-carnitine in myocardial enzyme abnormality caused by enterovirus in children with hand foot and mouth disease (HFMD). Methods 660 HFMD children patients with myocardial enzyme abnormality from May 2013 to June 2016 were enrolled and randomly divided into three groups. Group A(n=220)was treated with 1′6-FDP,group B with L-carnitine and group C with L-carnitine combined with 1′6-FDP. All groups were given routine anti-virus and symptomatic treatment. The clinical efficacy was compared across the three groups in terms of myocardial enzyme spectrum,heart rate,ECG,severe conver-sion rate before and after treatment. Results (1)Before treatment,there was no significant difference between the three groups in gender,age,course of disease,heart rate,myocardial enzyme spectrum and other indicators. (2)After treatment,the cure rate of HFMD in group B and group C were significantly higher than that in group A (both P<0.05);the rate of severe cases and the ECG normal rate in group B and group C were significantly lower than those in group A(both P<0.05),the time for heart rate resuming to normal in group B and in group C was all significantly shorter than that in group A(both P<0.05). There were no significant differences between group B and group C in clinical cure rate,severe conversion rate,recovery rate of ECG and heart rate recovery(all P>0.05).(3)In comparison with group A,after treatment,the levels of myocardial enzyme in group A and group B were decreased significantly(P < 0.05)and the recovery rates of myocardial enzyme in group A and the group B were significantly higher (P < 0.05),but no significant difference were observed between group A and group B (P>0.05). Conclusions For HFMD children with myocardial enzyme abnormality caused by enterovirus ,L-car-nitine together with myocardial nutritional therapy can significantly improve the myocardial enzyme indexes and electrocardiogram abnormality. It reduces the rate of severe cases and improve the prognosis.
