Bioelectrical Impedance Vector Analysis and Brain Natriuretic Peptide in the Evaluation of Patients with Chronic Kidney Disease in Hemodialitic Treatment.

Introduction: Setting dry weight (DW) in hemodialysis (HD) patients is still a hard issue. Several clinical, hematochemical, and instrumental parameters have been considered. In the last years, bioelectrical impedance vector analysis (BIVA) became the main method to evaluate body composition and water body percentage.
