Infusion of Furosemide to Improve Diuretic Efficiency in Acute Heart Failure (INFUSE-AHF)

keskiviikko 1. heinäkuuta 2026 päivittänyt: University of Aarhus

Infusion of Furosemide to Improve Diuretic Efficiency in Acute Heart Failure (INFUSE-AHF)

Acute heart failure is a condition where the heart suddenly cannot pump blood well enough for the body's needs. Many people admitted to the hospital with acute heart failure have too much fluid in the body. This can cause shortness of breath, swelling, and the need for treatment with water-removing medicine.

Furosemide is a commonly used water-removing medicine that is given into a vein to treat fluid overload. It can be given in different ways. One way is as a continuous infusion, where the medicine is given slowly over time through a pump. Another way is as repeated injections given several times a day. It is not known whether one of these ways is better than the other for removing excess fluid in people with acute heart failure.

The purpose of this study is to compare two ways of giving furosemide into a vein: Continuous infusion started with an initial extra dose, and bolus injections given three times a day. About 436 adults admitted to hospitals in Denmark with acute heart failure and fluid overload will take part. Participants will be randomly assigned to one of the two treatment groups. This means that chance will decide which treatment method each participant receives.

The main thing the researchers will measure is how much body weight participants lose about 3 days after randomization. Weight loss is used as a measure of how much excess fluid has been removed.

Tutkimuksen yleiskatsaus

Yksityiskohtainen kuvaus

INFUSE-AHF is an investigator-initiated, multicentre, open-label, pragmatic, randomized clinical trial conducted at hospitals in Denmark. The trial compares two commonly used ways of administering intravenous furosemide in adults hospitalized with acute heart failure and volume overload: Continuous infusion preceded by a loading dose, and bolus injections administered three times a day.

The rationale for the trial is that intravenous loop diuretics are standard treatment for acute heart failure with volume overload, but the optimal method of administration remains uncertain. Previous evidence has not established whether continuous infusion or bolus injections are superior. In addition, continuous infusion without an initial loading dose may delay achievement of effective plasma concentrations. The INFUSE-AHF trial, therefore, specifically evaluates continuous infusion preceded by a loading dose compared with bolus injections three times a day.

The trial includes three phases. The inclusion phase starts when a potential participant is identified during hospitalization and ends when the first dose of trial treatment is administered. The treatment phase starts with the first administration of intravenous furosemide and continues until the last weight measurement on the morning of Day 4. The follow-up phase starts after the treatment phase and continues until 30 days after the first injection.

Participants are randomized in a 1:1 ratio to one of the two treatment strategies. In the continuous infusion group, an initial loading dose is administered immediately before the infusion is started. In the bolus group, furosemide is administered as bolus injections three times a day, and the first bolus includes an additional dose to mirror the loading dose strategy. Daily intravenous furosemide doses are determined according to the participant's oral loop diuretic dose at admission using a predefined dosing algorithm. During the first part of the treatment period, doses are protocolized. On the morning of Day 3, the treating clinician may increase the dose, maintain the same dose, or stop intravenous treatment according to the protocol and the participant's clinical status.

Approximately 436 participants will be enrolled. The primary endpoint is net weight loss 3 days, equivalent to approximately 72 hours, after randomization. Secondary endpoints include net weight loss 2 days after randomization, change in dyspnea on a Visual Analog Scale 3 days after randomization, days alive out of hospital to Day 30, and length of hospital stay. Safety endpoints include acute kidney injury, severe electrolyte disturbances, incidents, and side effects.
