Abstract/OtherAbstract:
Acute heart failure syndromes are a common cause of emergency department visits and hospitalization in North America and Europe. Although in-hospital mortality is relatively low, the postdischarge mortality and rehospitalization rates can be as high as 10-15 and 30%, respectively, within 60-90 days following discharge. It appears that the main reason for admission and readmission for heart failure is related to congestion manifested by dyspnea, jugular venous distension and edema. Often, congestion is associated with dilutional hyponatremia that is difficult to treat. Hyponatremia is an important predictor of increased mortality and the available therapies to treat congestion and/or hyponatremia are often ineffective and/or unsafe. Accordingly, there is an unmet need to develop a new agent that effectively relieves congestion due to high filling pressure without worsening renal function and improving or normalizing serum sodium in hyponatremic patients. This paper provides an overview of a new compound, tolvaptan, an oral selective V(2)-vasopressin antagonist in light of the recently published Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST) trial. The biochemical and pharmacological properties are discussed in conjunction with its clinical efficacy and safety, exploring the potential role of tolvaptan in the management of acute heart failure syndromes presenting with or without hyponatremia.
