About this trial
This is an interventional treatment trial for Acute Decompensated Heart Failure focused on measuring Acute Decompensated Heart Failure, Diuretics
Eligibility Criteria
Inclusion Criteria:
- Greater than or equal to 18 years of age
Hospitalized for acute decompensated heart failure (ADHF) secondary to fluid overload as defined by the presence of at least
- 1 symptom (e.g. dyspnea, orthopnea, paroxysmal nocturnal dyspnea) AND
- 1 sign (e.g. rales on auscultation, > 2+ peripheral or presacral> edema, hepatomegaly, ascites, jugular vein distension > 7 cm, pulmonary vascular congestion on chest radiography)
- Inadequate response to IV diuretics and requiring additional diuresis as determined by primary medical team
- Received less than six doses of IV furosemide OR enrolled within 72 hours of hospital admission
- Anticipated need for intravenous diuretic therapy for at least 48 hours
- Able to provide informed consent
Exclusion Criteria:
- Receiving a continuous infusion loop diuretic during current hospital visit
- Substantial diuretic response to pre-randomization diuretic dosing such that higher doses of diuretic would be contraindicated (based on judgement of patient's primary team)
- Planned or ongoing intravenous vasoactive therapy (e.g. inotrope, vasodilator) or mechanical support (e.g. intra-aortic balloon pump, ventricular assist device) for ADHF during this hospitalization

- Systolic blood pressure < 90 mmHg
- Serum creatinine > 3 mg/dL at baseline or renal replacement therapy including ultrafiltration
- Serum potassium < 3.5 mEq/L (3.0 - 3.4 mEq/L allowed if supplemental potassium is being administered)
- Serum magnesium < 1.6 mg/dL (1.4 - 1.5 mg/dL allowed if supplemental magnesium is being administered)
- Acute coronary syndrome or hemodynamically significant arrhythmias causing worsening HF

Active Comparator
Active Comparator
Arm Label
Addition of PO Thiazide Diuretic
IV furosemide dose escalation
Arm Description
Addition of oral metolazone 5 mg daily to current intravenous bolus furosemide. All subjects will continue their current dose of intravenous bolus furosemide.
Current IV furosemide dose will be escalated to 2-2.5 x current dose, given as either IV bolus or continuous infusion over 24 hours.
Outcomes
Primary Outcome Measures
Daily Net Fluid Output on Day 2 (24-48 Hours After Randomization)
Net fluid output = fluid output during 24-48 hours after randomization - fluid intake during 24-48 hours after randomization. A negative value means that daily fluid intake was less than the daily fluid output.
Secondary Outcome Measures
Daily Net Fluid Output on Days 1, 3, and 4
Daily net fluid output = daily fluid output - daily intake. A negative value means that daily fluid intake was less than the daily fluid output.
Daily Urine Output (mL Urine Out Per mg Furosemide (IV Equivalent) Received)
Daily Weight
Patient Global Assessment Scale
Scale range: 1-5 Which of the following best describes your overall health state today?
= markedly worse
= worse
= neither better nor worse
= better
= markedly better
Physician Global Assessment Scale
Scale range: 1-5 Which of the following best describes the patient's overall health state today?
= markedly worse
= worse
= neither better nor worse
= better
= markedly better
Need for Additional or Alternative Diuretic (Crossover) or Other Vasoactive Therapy (Study Failure)
Patients will be considered a treatment failure if they require additional diuretic (including crossover to the alternative study arm) or require IV vasoactive drug therapy (e.g. vasodilators including nitroglycerin or inotropes) as deemed appropriate/necessary by their medical team.

5. Study Description
Brief Summary
The purpose of this prospective, randomized, open-label study is to compare two diuretic strategies in patients with acute decompensated heart failure (ADHF): the addition of an oral thiazide diuretic to intravenous bolus (IVB) loop diuretic will be compared to transition from IVB to continuous infusion (CI) loop diuretic.
Detailed Description
Patients hospitalized for ADHF secondary to fluid overload and who are experiencing an inadequate response to IVB furosemide and require additional diuresis will be enrolled. Patients will be randomized to one of two treatment arms: the addition of oral metolazone to continued IVB furosemide versus transition from IVB to CI furosemide. A suggested algorithm for initial dosing and titration of these two diuretic strategies will be provided. Baseline and daily data collection will include various efficacy and safety endpoints including daily net urine output and weight, patient and physician global assessment scale, length of stay, 30-day death or rehospitalization, vital signs, electrolytes, and renal function. Clinically meaningful efficacy and safety endpoints will be compared.
