title: The heart in acute glomerulonephritis: an echocardiographic study.
abstract: Patients with acute glomerulonephritis often are seen with signs suggesting heart failure. Whether these signs are due to fluid overload secondary to kidney damage only, or whether there is associated myocardial damage has not been elucidated. Fourteen children with acute glomerulonephritis were studied by echocardiography during the edematous phase of the disease and five months later to evaluate cardiac function in this disease. Left ventricular size and function remained normal in all children throughout the study. The most consistent finding was enlargement of the left atrium during the edematous phase with a return toward normal values five months later. There was no correlation between blood pressure and the echocardiographic findings. This study suggests that signs of heart failure in acute glomerulonephritis are not due to myocardial damage but probably reflect fluid overload.
