(2025). Impact of natriuresis on worsening renal function during episodes of acute heart failure. Revista Española de Cardiología (English Edition), 78(3), 196-205. https://doi.org/10.1016/j.rec.2024.07.0061885-5857https://hdl.handle.net/11268/16370Worsening renal function (WRF) is a frequent complication in acute heart failure (AHF) with a controversial prognostic value. We aimed to study the usefulness of natriuresis to evaluate WRF. We conducted an observational, prospective, multicenter study of patients with AHF who underwent a furosemide stress test. The patients were classified according to whether WRF was present or absent and according to the median natriuretic response. The main endpoint was the combination of mortality, rehospitalization due to HF, and heart transplant at 6 months of follow-up.engNatriuresisInsuficiencia CardíacaBiomarcadoresjournal article10.1016/j.rec.2024.07.006embargoed accessEnfermedad cardiovascularInvestigación médicaGoal 3: Ensure healthy lives and promote well-being for all at all ages
