This study investigated the effect of L-carnitine supplementation in children with dilated cardiomyopathy, a severe cardiovascular disease manifesting in chronic heart failure. 29 children were involved in this study. Children in the experimental group were administered 50-100 mg/kg/day oral L-carnitine (19 children) in addition to conventional treatment. Heart function was determined after 1, 3, 6, and 12 months. After one year of treatment, heart function significantly improved in the experimental group compared with the control group. This means that oral L-carnitine supplementation may enhance the efficacy of conventional therapies in these patients. More details can be found in the study.
