Study Arms (3)
Standard of Care (Group 1)
NO INTERVENTIONPatients in Group 1 received standard of care treatment per heart failure guidelines at the discretion of the primary cardiologist involved in the patient's care.
IV Placebo Infusion
PLACEBO COMPARATORPatients in Group 2 received IV saline infusion (20-40 ml) concentrated by the pharmacist to minimize fluid intake.The infusions were continuous over 3 hours, biweekly over a one-month period.
IV Furosemide Infusion
EXPERIMENTALThe dose assignments were categorized into low dose (20 mg bolus with 20 mg/hour infusion sessions and 2 ml saline), intermediate dose (40 mg bolus with 40 mg/hour infusion sessions and 4 ml saline) and high dose (80 mg bolus with 80 mg/hour infusion sessions). The infusions were continuous over 3 hours, biweekly over a one-month period.Infusions were held at the discretion of the physician utilizing a written protocol (creatinine 25% above baseline, SBP \<80 mmHg or symptoms of presyncope).

- Masking Details
- Subjects, nurses and treating physicians will be blinded to whether the subjects are receiving continuous IV furosemide (group 2) or continuous IV placebo (group 3). The pharmacist will not be blinded to help administer the appropriate medication. Because the trial will be double-blinded, safety laboratory tests will be performed for each subject for the duration of the trial, regardless of the treatment arm, and will be monitored by the research coordinator. Similarly, monitoring of potential side effects will be continuous and irrespective of treatment assignment. Outcomes assessor will be blinded.
