Summary

Hyponatremia is a common finding in acute heart failure (HF) patients and is associated with worse prognosis. In addition to its prognostic value, hyponatremia may have importance during the acute management of HF. We've recently shown that acute or chronic hyponatremia, especially \<130 mEq/L, was associated with higher loop diuretic dose requirements and more frequent need for escalation of the diuretic regimen to achieve the same level of diuresis as normonatremic HF patients. Aquaresis with tolvaptan represents a potentially advantageous approach to the management of volume overload in HF, especially in patients presenting with concomitant hyponatremia. The purpose of the current study is to prospectively evaluate the comparative efficacy and safety of a tolvaptan-based diuretic regimen compared to conventional diuresis with a furosemide-based regimen on short-term clinical and treatment outcomes in hyponatremic acute HF patients.

This will be a prospective, open-label, parallel-group, randomized study comparing a tolvaptan-based aquaretic regimen to a conventional continuous infusion loop diuretic-based regimen of furosemide. Up to 55 (target sample size of 50) adult subjects admitted with acute HF and signs of volume overload, and serum sodium less than 135 mEq/L will be randomized to tolvaptan or furosemide treatment arms. The initial 24 hours of study treatment will compare tolvaptan monotherapy to furosemide monotherapy. After the initial 24 hours, treatment regimens may be altered to achieve desired clinical goals. Patients will be followed for up to 96 hours and at discharge for study purposes.
