 Most frequent causes of death in Duchenne muscular dystrophy(DMD) are heart and respiratory failure, but long-term follow-up of cardiac function in DMD has rarely been reported. In 44 inpatients with DMD, echocardiography, human atrial and brain natriuretic peptides(hANP, BNP) were repeatedly examined during the past 7.9±0.3 years. We found that the severity of echocardiographic cardiac dysfunction(LVEF<40%, LVDd≧55mm) was reflected by neither age, skeletal muscle weakness nor occurrence of respiratory failure, but showed different courses of progression among the patients. In patients with very severe cardiac dysfunction, serum concentrations of hANP and BNP were elevated. Hence, in routine follow-up with echocardiography, hANP and BNP seem useful to assess cardiac involvement in DMD.
