Objective: Up to 50% of patients hospitalized for acute heart failure (AHF) show resistance to diuretics. This condition contributes to a prolonged hospital length of stay and a higher risk of death. This review aimed to investigate whether a diuretic therapeutic approach more effective than furosemide alone exists for patients with diuretic-resistant AHF.
Materials And Methods: We identified all randomized controlled trials (RCTs) evaluating diuretic therapy in patients with diuretic-resistant AHF. We searched Pubmed, BioMed Central, and Cochrane CENTRAL databases.
Results: Six RCTs were identified, involving a total of 845 patients. The P-score ranges from 0.6663 for furosemide to 0.2294 for the tolvaptan-furosemide. We found no significant differences in efficacy for any drug comparison.
Conclusions: None of the diuretics considered in RCTs performed to date (tolvaptan, metolazone, hydrochlorothiazide, indapamide) appear to be more effective than furosemide therapy alone for the treatment of patients with diuretic-resistant AHF.

Diuretic drugs act on electrolyte transporters in the kidney to induce diuresis and are often used in chronic kidney disease (CKD), given that nephron loss creates a deficit in the ability to excrete dietary sodium, which promotes an increase in plasma volume. This rise in plasma volume is exacerbated by CKD-induced systemic and intra-renal activation of the renin-angiotensin-aldosterone-system, which further limits urinary sodium excretion. In the absence of a compensatory decrease in systemic vascular resistance, increases in plasma volume induced by sodium retention can manifest as a rise in systemic arterial blood pressure.

Hypertonic saline with high dose furosemide improves refractory heart failure. In this case series of 10 patients of refractory acute decompensated heart failure, effect of HSS with furosemide was compared with furosemide alone. Patients responded to the therapy better, with faster decongestion, without significant adverse effects or worsening renal function.

Background: Diuretic resistance is a relevant clinical issue in acute heart failure (AHF), but a standardized, quantitative definition is still missing. The aim of this analysis was to highlight discrepancies between previously proposed definitions of diuretic response and to propose a new urinary sodium (NaU)-based definition of diuretic efficiency (DE) to identify diuretic resistant (DR) patients.
Methods: Three historical definitions of diuretic response and a new NaU-based DE definition, evaluating total NaU after the first diuretic bolus per 40 mg furosemide administered, were applied in a retrospective analysis to an AHF population treated with intravenous (i.

Guidelines recommend intravenous loop diuretics as first-line therapy for patients hospitalized with acute heart failure (AHF) and volume overload. Additional agents can be used for augmentation, but there is limited guidance on agent selection. The study objective was to determine if chlorothiazide or metolazone is associated with differences in diuretic efficacy or safety in loop diuretic-resistant patients with AHF and renal dysfunction (eGFR <45 mL/min/1.

Background: Some patients with cardiorenal syndrome 1 and congestion exhibit resistance to diuretics. This scenario complicates management and is associated with a worse prognosis. In some cases, rescue treatment may be considered by starting kidney replacement therapies or ultrafiltration.
