Heart Failure; With Decompensation
Conditions
Brief summary
The purpose of this study is to determine the safety and effectiveness of ultrahigh dose diuretics compared to standard dose diuretics over 24 hours in patients with decompensated heart failure.
Interventions
Bumetanide will be administered via intravenous (IV) infusion at a dose of 12.5 mg two times a day (BID) for 2 doses total within 24 hours.
Furosemide will be administered via intravenous (IV) infusion at usual doses (twice the home dose of oral daily diuretic in furosemide equivalents) administered as 2 doses total within 24 hours. Furosemide equivalents will be considered as follows (40 mg of intravenous furosemide = 1 mg oral bumetanide or 40 mg of torsemide or 80 mg of oral furosemide consistent with prior literature). The lowest dose of furosemide administered during the study will be 40 mg IV two times a day (BID) and the maximum dose will be 100 mg IV BID.
