title: Cardiomyopathy: a late complication of hemolytic uremic syndrome.
abstract: This report describes a child who presented with classic hemolytic uremic syndrome (HUS) and 4 months later developed a life-threatening but reversible cardiomyopathy with global cardiac dysfunction and a left ventricular ejection fraction of 14%. There was no evidence of electrolyte abnormalities, anemia, hypertension, severe fluid overload, or viral infection. Endomyocardial biopsies were consistent with a dilated cardiomyopathy. This paper highlights the importance of considering the diagnosis of associated cardiomyopathy when presenting with late-onset edema following HUS.
