Suivi de la natriurèse pour le traitement de la décompensation cardiaque

Pharmacologically induced diuresis in the treatment of acute heart failure (AHF) is commonly assessed using clinical congestion scores or daily weight monitoring, but these methods may lack precision due to examiner subjectivity and variability in weight fluctuations. The European Society of Cardiology recommends measuring natriuresis to evaluate the diuretic response and adjust the dosage accordingly. Higher natriuresis has been associated with better clinical outcomes following an episode of AHF in observational studies. Recent prospective trials have shown that a natriuresis-guided strategy increases cumulative sodium excretion and shortens hospital stay without impacting clinical outcomes. Its routine implementation is limited by the practical challenges associated with standardized urine sampling.
