Prognostic features in childhood idiopathic dilated cardiomyopathy
Published online by Cambridge University Press: 19 August 2008
Abstract
The clinical course, noninvasive findings and outcome of 25 infants and children with idiopathic dilated cardiomyopathy were reviewed retrospectively to identify factors predictive of outcome both at diagnosis and at short-term follow-up. Patients, stratified by clinical status at last visit, were assigned to groups encompassing those who were asymptomatic and receiving on medication, those patients who were symptomatic or needed medication to control symptoms, and those who were dead, awaiting heart transplantation, or had undergone transplantation. Older age at diagnosis was strongly associated with poor clinical outcome (p=0.005), as was the presence of arrhythmias at the time of diagnosis (p=0.008) and at short-term follow-up-(p=0.003). Echocardiographic studies at diagnosis failed to predict eventual clinical outcome, although patients who ultimately recovered and did not need medications tended to demonstrate improvement in or resolution of echocardiographic abnormalities within 6 months of diagnosis.
