Study Summary

Broad Objectives: To determine the comparative efficacy of commonly employed strategies to overcome loop diuretic resistance when added to concomitant loop diuretics in hospitalized decompensated heart failure patients with hypervolemia Specific Aims: 1. Compare the 48-hour weight change of either intravenous chlorothiazide or oral tolvaptan compared to standard-of-care oral metolazone when combined with standardized loop diuretic dosing for diuretic resistance in decompensated heart failure 2. Compare the adverse effects of electrolyte depletion and renal function changes between intravenous chlorothiazide or oral tolvaptan compared to standard-of-care oral metolazone when combined with standardized loop diuretic dosing for diuretic resistance in acute heart failure 3. Pharmacoeconomic analysis of the direct costs of intravenous chlorothiazide or oral tolvaptan compared to standard-of-care oral metolazone when combined with standardized loop diuretic dosing for diuretic resistance in acute heart failure The investigators will conduct a dual center, randomized, double-blind, double-dummy, parallel design trial comparing: oral metolazone, intravenous chlorothiazide, or oral tolvaptan, in combination with loop diuretics in 60 patients hospitalized for hypervolemic decompensated heart failure and displaying loop diuretic resistance.

Primary Outcome

The primary outcome will be 48-hour standing scale weight change (kg) from enrollment among the metolazone, intravenous chlorothiazide, and tolvaptan arms, using metolazone group as the comparator group for all other groups.
