An evaluation of cardiac function in malnourished children by non-invasive methods.

Forty-six malnourished children between 3-48 mo with varying grades of malnutrition (PEM) were evaluated for left ventricular function by echocardiography. None of these children had any pre-existing cardiac disease, chronic illness or significant anemia. Children with Grades III and IV PEM had significantly smaller cardiac chamber size and ventricular wall thickness as compared to normally nourished children. Cardiac output as well as other indices of left ventricular function (percentage fractional shortening, mean rate of circumferential fibre shortening and ejection fraction) were also significantly decreased in severe PEM. The atrophic PEM heart does appear to show left ventricular dysfunction in moderately severe malnutrition.
