Dilated cardiomyopathy associated with haemolytic uraemic syndrome.
In two children with the haemolytic uraemic syndrome dilated cardiomyopathy occurred in the absence of hypertension, or fluid or electrolyte disturbance. These cases presented with acute left ventricular failure. Echocardiography showed left ventricular dilatation and reduced contractility. There was also ventricular wall thickening, which persisted. Twelve other children with haemolytic uraemic syndrome had prospective echocardiography. Eleven of them showed no evidence of cardiomyopathy and in one transient dilatation and reduced contractility developed without clinical signs. Dilated cardiomyopathy is a rare but important extrarenal manifestation of the haemolytic uraemic syndrome and is best demonstrated by echocardiography.
