Reverse cardiac remodeling after fluid balance optimization in patients with end-stage renal disease.

BACKGROUND

In patients with end-stage renal disease (ESRD) undergoing hemodialysis, cardiovascular diseases, and in particular chronic heart failure are the leading causes of morbidity and mortality. Nevertheless, few data are available about the impact of fluid optimization on echocardiographic parameters of cardiac function in patients with ESRD.

METHODS AND

RESULTS

In five patients with ESRD undergoing hemodialysis who had developed nonischemic dilated cardiomyopathy, an optimal fluid volume management based on a strict bioelectrical impedance analysis-assisted dry weight target and dietary sodium and water restriction led to left ventricular reverse remodeling and improvement in hemodynamic parameters. The reverse remodeling further improved after kidney transplantation.

CONCLUSIONS

This case series supports the possible beneficial effect of volume status optimization on cardiac function and the potential reversibility of cardiac dysfunction after kidney transplantation.
