Chronic fluid overload is a common issue in patients undergoing hemodialysis. In present study, we aimed to investigate fluid volume parameters by bioimpedance analysis (BIA) and their relationship to hemodynamic parameters as systolic and diastolic blood pressure, pulse wave velocity (PWv), PP, cardiac index (CI) and cardiac output (CO) in patients ongoing hemodialysis. METHODS: One hundred end stage renal disease patients who were medically stable and undergoing dialysis treatment for at least 3 months were enrolled to the study. Body compositions were analyzed with the BIA technique (BCM, Fresenius) that estimates systolic and diastolic blood pressure, body mass index (BMI) lean tissue index (LTI), extracellular volume (ECW), intracellular volume (ICW), lean tissue mass (LTM) and phase angle levels. PWv, pulse pressure, CI, CO, systolic pressure augmentation (AIx) and total vascular resistance (TVR) were evaluated with PWv analysis monitor (Mobil-O-Graph). RESULTS: The mean age was 47.5 ± 16.2. Ultrafiltration volume and overhydration frequency were positively correlated with systolic blood pressure, ECW, ICW, BMI (p<0.05) and hemodynamic parameters as PWv, PP, CO, TVR, CI and AIx (p<0.001), and negatively correlated with LTI (p <0.05). PP, CO, TVR, CI, AIx, Kt/V, E/I and phi50 were the predictors of pulse wave velocity (p<0.05). Systolic blood pressure, PP, CO, TVR, CI, AIx, PWv, ECW, ICW and E/I were the predictors of overhydration (p<0.001). DISCUSSION and CONCLUSION: Present study concluded that overhydration is associated with increased PWv, systolic blood pressure, PP and vascular resistance
