ObjectiveCardio-Renal Syndrome (CRS) is a condition, which is more frequently observed in clinical practice. The aim of this study is to explore nutritional status and intrarenal arterial stiffness in patients affected by CRS.Patients and methods14 consecutive CRS patients, screened for anthropometry, biochemistry, nutritional and metabolic status underwent renal Doppler ultrasound and whole-body bioimpedance spectroscopy (BIS).ResultsWe found a positive correlation between phase angle (PA) and CKD-EPI and MDRD (p=0.011 and p=0.007), and between body mass index and renal resistive index (RRI) (p=0.002). Finally, we found a negative correlation between fat-free mass and RRI (p=0.024).ConclusionsBody composition assessment may improve the care of patients with chronic kidney disease (CKD). Also, BIS may help identify changes in hydration status in CKD patients resulting as a significant predictor of mortality.
