简要总结
One tolvaptan 15 mg tablet or placebo tablet will be orally administered once daily in the morning for up to 14 days to heart failure patients with volume overload that does not show adequate response to other diuretics such as loop diuretics in order to investigate the effect of tolvaptan on the mid- to long-term prognosis of the target population. The efficacy of tolvaptan during the treatment period will also be investigated.

主要结局
Mortality （Number of Death）
时间窗: Week26
Statistical comparison was not done.
Cummulative Incidence of Events at Week 26
时间窗: Week 26
From start day of IMP administration to final day of follow up period, 1) and 2) below were defined as event 1. Death from cardiovascular events 2. Worsening of heart failure * The day of re-hospitalization due to worsening of heart failure * The day of medication below due to worsening of heart failure Phosphodiesterase III inhibitors (Injection), Catecholamine preparations (Injection), Colforsin preparations (Injection), Diuretics (Injection), Human atrial natriuretic peptide preparations (Injection)：Calperitide (Injection)
Number of Subjects Whose Lower Limb Edema Severity Grading Improved by One or More Grade
时间窗: Day15
Of the subjects who had lower limb edema at baseline, the number of subjects whose lower limb edema severity grading. Statistical comparison was not done.
Jugular Venous Distension
时间窗: Day15
The comparison of the average of amount of change from baseline. Statistical comparison was not done.
Body Weight
时间窗: Day15
The comparison of the average of amount of change from baseline. Statistical comparison was not done.
Change in Liver Size From Baseline
时间窗: Day15
The comparison of the average of amount of change from baseline. Statistical comparison was not done．
Pulmonary Rales
时间窗: Day15
Of the subjects who had pulmonary rales at baseline, the number of subjects whose symptom was resolved at completion of treatment. Statistical comparison was not done.
Third Heart Sound
时间窗: Day15
Of the subjects who had third heart sound at baseline, the number of subjects whose symptom was resolved at completion of treatment. Statistical comparison was not done.
Cardiothoracic Ratio
时间窗: Day15
Investigator majored Thoracic length and Cardiac length from chest X-ray. Cardiothoracic Ratio was calculated from Cardiac length/Thoracic length\*100. Lowering of Cardiothoracic Ratio suggests recovery from heart congestion. The comparison of the average of amount of change from baseline. Statistical comparison was not done.
Pulmonary Congestion
时间窗: Day15
Of the subjects who had pulmonary congestion at baseline, the number of subjects whose pulmonary congestion severity grading showed an improvement of one grade or more (eg, moderate to mild) at completion of treatment. Statistical comparison was not done.
Plasma Brain Natriuretic Peptide (BNP) Concentration
时间窗: Day15
The comparison of the average of amount of change from baseline. Statistical comparison was not done.
Dypnea
时间窗: Day15
Of the subjects who had dyspnoea at baseline, the number of subjects whose symptom was resolved at completion of treatment. Statistical comparison was not done.
Number of Subjects Whose New York Heart Association (NYHA) Classification Improved by One More Grade From Baseline
时间窗: The day after last IMP administration and Baseline
New York Heart Association (NYHA) Classification is below ClassI：No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath). ClassII：Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath). ClassIII：Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea. ClassIV：Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases.
