Brief Summary:
DiurHF is a prospective, multicenter, observational, study that compares continuous with intermittent infusion of furosemide in patients admitted with a diagnosis of ADHF. Previous pilot study design was planned to anticipate a larger multicenter trial able to definitively evaluate the optimal loop diuretic use strategy in patients with ADHF.

Condition or disease Intervention/treatment
Acute Heart Failure Drug: Continuous Furosemide Infusion Drug: Intermittent Furosemide Infusion

Detailed Description:

The use of intravenous loop diuretics is a cornerstone of therapy for acutely decompensated heart failure (ADHF); significant concerns have been raised regarding risks and benefits of loop diuretics, particularly about dosage and administration regimen.

Recent guidelines recommend the use of these drugs to reduce left ventricular filling pressure, avoid pulmonary edema, and alleviate peripheral fluid retention.

Some studies have provided guidelines for the administration of these drugs in clinical practice, but data interpretation remains challenging due to the frequent exclusion of patients with kidney disease from major ADHF clinical trials. Therefore, it is not clear if continuous infusion is better than intermittent boluses in terms of decongestion, maintenance of renal filtration function and prognosis.

On the other hand, continuous administration should provide a more constant delivery of the drug into the tubule, potentially reducing these phenomena.

The aim of the study is to evaluate the better loop diuretic intravenous administration in terms of renal function, congestion signs, BNP and outcome.

  8. BUN changes [ Time Frame: From date of randomization until the discharge (7-12 days) ]
    mean paired changes of blood urea nitrogen (BUN) in the two groups during hospitalization.

  9. Reduction of edema [ Time Frame: From date of randomization until the discharge (7-12 days) ]
    Evaluation of edema regression (or not) after treatment in the two groups.

  10. Reduction of dyspnea [ Time Frame: From date of randomization until the discharge (7-12 days) ]

  12. Diuretic efficiency: (Weight loss/days of infusion)/ (Mean daily furosemide dosage/40 mg of furosemide) [ Time Frame: From hospital admission until the discharge (7-12 days) ]
    Evaluation of persistence of congestion (or not) and incidence of AKI (or not) according to quartiles of diuretic efficiency.

  13. High (> 125 mg/die) versus low (<125 mg/die) intravenous diuretic dosage [ Time Frame: 180 days ]
    Number of patients with high in-hospital diuretic dosage who were affected by adverse outcome.
