Results: Compared with patients remaining residual diuresis, patients loss residual diuresis had higher left ventricular volume index (104.83 ± 47.32 versus 90.73 ± 44.52 ml / m2; p <0.05); higher left ventricular mass index (193.21 ± 65.42 mg / ± 55.85 versus 159.10; p <0.0001) and lower left ventricular ejection fraction (55.27 ± 11, 99 ± 11.45 versus 58.97 g / m2, p <0.05) significantly.
