{Abstract}: Acute heart failure (AHF) is characterized by the emergence or intensification of symptoms and signs indicative of congestion or systemic hypoperfusion, stemming from an underlying structural or functional cardiac disorder. Intravenous loop diuretics play a pivotal role in achieving effective decongestion and ensuring clinical stability; the efficacy of these medications is crucial for determining the patient's hospital course and early outpatient progression. Individuals who exhibit a suboptimal response to diuretics or develop diuretic resistance (DR) are at an elevated risk for cardiovascular mortality and readmission due to AHF. However, there is a lack of standardized definition and diagnostic criteria for DR. Early identification of patients with DR is critical, as they may benefit from more aggressive decongestion strategies to mitigate this resistance. Natriuresis, the excretion of sodium in urine, serves as a direct measure of a diuretic's effectiveness. Low levels of natriuresis have been linked to poorer outcomes. Several studies have underscored the prognostic significance of natriuresis across various heart failure scenarios. However, the relationship between natriuresis and in-hospital DR has not been extensively studied. Observational research has indicated that inadequate natriuresis following the administration of loop diuretics correlates with a diminished diuretic response and an increased likelihood of mortality and heart failure rehospitalization. Further investigation is warranted to assess the predictive value of basal natriuresis concerning DR, in-hospital outcomes, and early outpatient cardiovascular events. This would help in identifying patients who are likely to respond poorly to diuretic therapy and may require alternative or more intensive treatment approaches.
