Open AccessEarly treatment with tolvaptan improves diuretic response in acute heart failure with renal dysfunction
Poor response to diuretics is associated with worse prognosis in patients with acute heart failure (AHF). We hypothesized that treatment with tolvaptan improves diuretic response in patients with AHF.
