Ringaitiene D, et al. – The specialists applied the new ESPEN diagnostic criteria in order to determine the incidence of malnutrition (MN) in cardiac surgery patients. They also evaluated whether these criteria were concordant with the bioelectrical impedance analysis (BIA) provided phase angle (PA) in predicting early stages of malnutrition. In investigations, fewer patients were classified as malnourished by the new ESPEN definition as those identified by the BIA provided PA. These findings indicated that incorporation of the BIA provided PA into the new ESPEN definition might aid to diagnose the early stages of MN in the field of cardiac surgery.
