Oral Sodium to Preserve Renal EfficiencY in Acute Heart Failure

The investigators are proposing a prospective, randomized, double blinded, placebo-controlled single center study evaluating the role of co-administration of oral sodium chloride (NaCl) with intravenous diuretics in patients hospitalized with acute decompensated heart failure. The investigators are approaching this study with the hypothesis that the use of oral sodium chloride leads to improved effective diuresis (as measured by weight loss) and renal function as compared to placebo in patients hospitalized with acute decompensated heart failure undergoing aggressive intravenous diuretic therapy.
