Abstract

In clinical apparent heart and renal failure it is not always easy tofind the optimal sodium and water balance. Therefore, we investigatedthe use of tetrapolar bioelectrical impedance analysis (BIA) for estimation of water balance. To prove the quality of this method, we compared three types of acute water reduction: 1. hemodialysis (H, n = 8), 2. drug-induced diuresis (D, n = 8) and 3. sauna (S, n = 7). We determined the extracellular mass/body cell mass relation (ECM/BCM-Q) in patients with decompensated heart failure (HF) in comparison to healthy subjects (KO) and found a significant (p < 0.001) correlation between weight reduction and changes in total body water (TBW) in all three acute trials (S:r = 0.82; H:r = 0.96; D:r = 0.97). In 14 KO the ECM/BCM-Qwas 0.81 +/- 0.03, in patients with HF 1.46 +/- 0.09 (p < 0.001). Thesame difference occurred for reactance (KO 62 +/- 1.2 OMEGA and HI 33+/- 1.8 OMEGA, p < 0.001). Both groups could clearly be separated at an ECM/BCM-Q of 1.0 or at a reactance of 50 OMEGA. The results give evidence that an ECM/BCM-Q > 1 or a reactance < 50 OMEGA indicates clinical relevant non-compensated heart failure. These limits of normal water balance are also valid for patients on hemodialysis. Our results show that in patients with lower body weight (BMI 21 +/- 1 kg/m2) the water balance after hemodialysis was not optimal (ECM/BCM-Q 1.35 +/- 0.13), whereas in normal weight patients the water balance was well controlled after hemodialysis (ECM/BCM-Q 0.75 +/- 0.03). In contrast to simple weight control, a clear therapeutic aim can be established by BIA in patients with heart or renal failure, this means an ECM/BCM-Q < 1 or a reactance > 50 OMEGA.
