Interaction of malnutrition, N-terminal pro-B-type natriuretic peptide and ventricular remodeling in patients on maintenance hemodialysis.
Clinical Nephrology 2013 April
AIMS: The aim of the present study was to investigate the interaction of nutritional status, N-terminal probrain-type natriuretic peptide (NT-proBNP) and ventricular remodeling in hemodialysis patients.
METHODS: NT-proBNP was measured by immunoassay. Nutritional status was assessed using the subjective global assessment (SGA) and malnutrition-inflammation score (MIS). Transthoracic echocardiographic examinations were performed on all patients.
RESULTS: 44 patients undergoing maintenance hemodialysis were enrolled in this study. Malnourished patients had higher levels of extracellular water (ECW) per kg body weight (BWt) than well-nourished patients and higher levels of NT-proBNP. MIS was positively correlated with left ventricular mass index (LVMI), log NT-proBNP and ECW/BWt, and negatively correlated with fat mass and LV systolic dysfunction. LV systolic dysfunction, LVMI and MIS were independently associated with log NT-proBNP levels. Multiple regression analysis showed that log NT-proBNP, mean arterial pressure and ECW/BWt were independently associated with LVMI. However, MIS did not have an independent relationship to LVMI.
CONCLUSIONS: Malnutrition in hemodialysis patients is accompanied by volume overload and associated with increased log NT-proBNP levels independent of volume status, and these levels are independently associated with increased LVMI. This suggests a possibility that nutritional status may affect ventricular remodeling in hemodialysis patients.
