Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Efficacy 1) Alleviation of the signs of body fluid retention 2) Change of body weight 3) Changes in the daily urinary volume
Time Frame: At the day of discontinuation of tolvaptan or day 7, whichever comes first
|
1) Alleviation of the signs of body fluid retention by the 7th day of treatment with tolvaptan (or the day of discontinuation of the drug in cases where tolvaptan treatment has been discontinued before the 7th day) as compared with the observations made on the day before the start of treatment 2) Change of body weight by the 7th day of treatment with tolvaptan as compared with the level measured on the day before the start of treatment 3) Changes in the daily urinary volume by the 7th day of treatment with tolvaptan as compared with the values measured on the day before the start of treatment
|
At the day of discontinuation of tolvaptan or day 7, whichever comes first
|
Safety: adverse events Adverse events until 30 days after the end of treatment with tolvaptan
Time Frame: 30 days after tolvaptan withdrawal
|
30 days after tolvaptan withdrawal
|
|
Long-term outcome (1 year after tolvaptan administration) 1) Time from enrollment to cardiovascular events 2) Time from enrollment to re-hospitalization for aggravation of heart failure 3) Time from enrollment to all-cause death
Time Frame: 1 year after administration of tolvaptan
|
1) Time from enrollment to cardiovascular events within 1 year after administration of tolvaptan 2) Time from enrollment to re-hospitalization for aggravation of heart failure within 1 year after administration of tolvaptan 3) Time from enrollment to all-cause death within 1 year after administration of tolvaptan Cardiovascular events included death from heart failure, death from acute coronary syndrome, death from stroke, sudden death, death of unknown causes, death from other cardiovascular causes, readmission for heart failure, ventricular arrhythmia, acute coronary syndrome, and stroke. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Search for the factors related with the efficacy of tolvaptan therapy and long-term outcome 1) related factors regarding efficacy of tolvaptan 2 ) related factors regarding long-term outcome
Time Frame: 1 year after administration of tolvaptan
|
Exploratory analysis will be performed to determine which factors relate with the efficacy of tolvaptan therapy or long-term outcome.
Factors will include age, gender, medical past history, medication, NYHA classification, Nohria/Steavenson classification, laboratory data (Na, K, Cl, Albumin, Cr, BUN, AST, ALT, gamma-GTP, LDH, T-Bil, BNP, NT-pro BNP, copeptin, galectin-3,aldosteron,angiotensin II, renin, noradrenaline), heart rate, blood pressure, echocardiography data, intake/urine volume and osmolality.
