Key result
Adjusting dry weight via echocardiographic measurement of inferior vena cava diameter significantly reduced left ventricular mass (from 200 to 187 g, p=0.021) and mass index (p=0.014) in hemodialysis patients.

p-value: p=0.021
Adjusting dry weight using echocardiographic IVCD measurement in hemodialysis patients significantly reduces left ventricular mass and mass index compared to traditional clinical parameters.
Chang et al. (2004) conducted a cohort in End-stage renal disease (ESRD) on chronic hemodialysis (n=88). Dry weight adjustment via inferior vena cava diameter (IVCD) by echocardiography vs. Dry weight adjustment based on traditional clinical parameters was evaluated on Left ventricular mass (LVM) and left ventricular mass index (LVMI) (p=0.021). Adjusting dry weight via echocardiographic measurement of inferior vena cava diameter significantly reduced left ventricular mass (from 200 to 187 g, p=0.021) and mass index (p=0.014) in hemodialysis patients.
