A randomized, double-blind, multicenter, placebo-controlled, parallel study to evaluate the efficacy and safety of Tolvaptan in the treatment of patients with cardiac edema (body fluid retention caused by congestive heart failure) based on the conventional therapy.
To evaluate the efficacy and safety of Tolvaptan 15 mg on congestive heart failure patients with body fluid retention after current diuretic treatment, after continuous treatment of 7 days' oral Tolvaptan 15mg or placebo.
