Summary
The primary objective of this study is to compare the effects of oral Tolvaptan vs. placebo as an adjunct to fixed dose IV furosemide on dyspnea relief in patients with acute decompensated heart failure
The primary hypothesis is that the addition of oral Tolvaptan to fixed dose furosemide will be more effective at relieving dyspnea than fixed dose furosemide alone
