Continuous versus intermittent IV furosemide for acute heart failure

Official title: Continuous Versus Bolus Intermittent Loop Diuretic Infusion in Acutely Decompensated Heart Failure: Evaluation of Renal Function, Congestion Signs, BNP and Outcome

Run by University of Siena · NCT02638142 · Data updated 2026-11-12

This trial tests whether giving furosemide as a continuous IV infusion or as intermittent IV boluses works better for adults hospitalized with acute decompensated heart failure.

Is this trial a fit for you?

Likely a good fit

Adults (over 18) hospitalized with signs and symptoms of acute decompensated heart failure and BNP >100 pg/mL who do not meet the exclusion criteria are the intended participants.

Probably not a fit

Patients on dialysis, with creatinine >4 mg/dL, recent myocardial infarction, severe hypotension, or other excluded systemic illnesses would not be expected to benefit from participation.

What this trial studies

DiurHF is a prospective, multicenter observational comparison of two common intravenous loop diuretic regimens—continuous infusion versus intermittent boluses of furosemide—in patients admitted with acute decompensated heart failure. Participating Italian hospitals enroll adults with clinical signs of congestion and BNP >100 pg/mL and follow them through hospitalization. The study tracks changes in renal function, clinical congestion signs, BNP levels, and short-term clinical outcomes. Exclusions include end-stage renal disease, very high creatinine, recent myocardial infarction, severe hypotension, and major systemic illnesses.

Why it matters

Potential benefit: If successful, the results could point to a safer and more effective IV diuretic approach that relieves congestion while better preserving kidney function.

How similar studies have gone: Previous pilot and small trials have yielded mixed results about continuous versus bolus loop diuretics, so the approach has some supporting but inconclusive evidence.
