Background There is no evidence on how to use the information from bioimpedance analysis (BIA) devices in clinical management, including setting of target dry weight (DW), or improving outcomes in hemodialysis (HD) patients.
Methods Here, we investigate preferable cut off values of fluid status (extracellular water/total body water ratio; ECW/TBW) detected by a new and more accurate BIA device (Seca®) in 78 HD patients.
Results Patients with an ECW/TBW of more than 45% and human atrial natriuretic peptide (HANP) value of > 50 pg/mL had a higher blood pressure and cardio-thoracic ratio on chest x-ray examination.
Conclusions Our results suggests that ECW/TBW of more than 45% and HANP value of > 50 pg/mL were overhydrated and had a worse prognosis.
