(A) Daily urinary sodium excretion (UNaV) in rats with aortocaval fistula (ACF) and in sham controls. Notice two distinct patterns of sodium excretion in rats with ACF, compensated and decompensated rats. The lines representing compensated and decompensated CHF were significantly different (P < 0.01, by 2-way ANOVA). Similarly, the lines representing both CHF rats are significantly different from sham- operated animals (P < 0.01). (B) Glomerular filtration rate (GFR), and (C) Renal plasma flow (RPF) in rats with compensated and decompensated CHF and their sham controls. *P < 0.05 vs. sham-operated rats; #P < 0.05 vs. compensated rats with ACF. Values are means ± SEM.
