Objective:
Cardio-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 Methods:
14 consecutive CRS patients, screened for anthropometry, biochemistry, nutritional and metabolic status underwent renal Doppler ultrasound and whole-body bioimpedance spectroscopy (BIS).
Results:
We 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).
Conclusions:
Body 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.
