350Patients being hospitalized for acute heart failure and already receiving standard therapy will be randomized to receive either tolvaptan or placebo, based on the level of copeptin measured in their bloodstream. Patients with high copeptin levels will be able to participate in the trial, patients with low levels will be excluded. Patients being admitted to the observation unit for acute heart failure and already receiving standard therapy will be randomized to receive either tolvaptan or placebo without consideration of the copeptin level. The hypothesis is that patients receiving tolvaptan will have better improvement of shortness of breath than those receiving placebo, within 9 hours of drug administration.
Tolvaptan 30 mg. tablet for subjects enrolled prior to first 8 hours of coming to an emergency department. Repeated daily up to 5th day.
Patient in the placebo group will receive tolvaptan in addition to standard therapy
