Summary:Sleep disorders, autonomic dysfunction, and abnormal cognition are important comorbidities in adult patients with heart failure and are associated with disease progression, morbidity, and mortality. The clinical incidence of these conditions is unknown in children with heart failure. We sought to determine the incidence of symptoms that may be attributable to autonomic dysfunction among children with dilated cardiomyopathy and heart failure. We performed a retrospective chart review of patients with dilated cardiomyopathy seen at our institution between 1999 and 2005. We reviewed charts for symptoms of dysautonomia, sleep problems, or abnormal cognition. From the records of 204 pediatric patients, we identified 69 patients aged 7-18 years with severe dilated cardiomyopathy. Of these, 55 (80%) had symptoms attributable to dysautonomia, 20 (29%) had evidence of sleep disturbance, and 3 (4%) had abnormal cognition. Dysautonomia and sleep disturbances are prevalent in children with heart failure, congruent with studies of adult patients. Based on our data, it is not possible to draw conclusions about any cognitive deficits in this population. Because relatively few subjects' charts explored symptoms of sleep disturbance, we speculate that sleep symptoms may be underappreciated.
