Summary

Intravenous (IV) loop diuretics have been a key component in treating pulmonary edema since the 1960s and has a Class 1 recommendation in the 2021 guidelines for acute heart failure. However, no randomized clinical trials have investigated loop diuretics versus other interventions for acute heart failure, and clinical knowledge of the hemodynamic effects of furosemide is based in studies from the 1970s. In this study, we aim to assess the acute effect of furosemide on cardiac filling pressures and pulmonary congestion.

Hypothesis:

Administration of furosemide induces a hyperacute (within 30 minutes) lowering of cardiac filling pressures and pulmonary congestion before significant diuresis occurs.

Design:

A prospective, interventional study including 20 patients admitted due to a clinical diagnosis of acute heart failure with pulmonary congestion.

Intervention:

80 mg of furosemide is administered IV. Measurements include blood pressure, peripheral oxygen saturation, pulmonary fluid content by ReDS\*, ultrasound examination of heart and lungs, and assessment of cardiac filling pressures with doppler and strain analysis. Measurements are repeated at several time points until 6 hours have passed.

Conditions

  • Acute Heart Failure

Interventions

DRUG

Furosemide Injection

Intravenous administration of 80 mg furosemide is followed by assessing blood pressure, peripheral oxygen saturation, pulmonary fluid content by ReDS\*, and ultrasound examination of heart and lungs, including assessment of filling pressures with doppler and strain analysis. These measurements are repeated at multiple time points until 6 hours have elapsed.
