SURE-HF: Urinary Sodium-Guided Diuretic Therapy in Heart Failure

Официальное название

Urinary Sodium-Guided Optimization of Diuretic Therapy in Patients With Worsening Heart Failure: Rationale and Design of a Pragmatic Randomized Controlled Trial (SURE-HF Trial)

Обзор

The SURE-HF trial is a pragmatic, multicentre, randomized controlled study evaluating natriuresis-guided optimization of intravenous loop diuretic therapy in patients hospitalized with worsening heart failure (WHF). The study aims to determine whether serial urinary sodium assessment combined with a structured decongestive treatment algorithm improves decongestion, reduces the need for therapy escalation, and enhances discharge readiness compared with standard care. Participants will be randomized to standard urine output-guided therapy or natriuresis-guided decongestive strategies using different intravenous loop diuretic administration regimens. The study integrates bedside diagnostic tools including lung ultrasound, inferior vena cava assessment, focused echocardiography, and serial clinical congestion monitoring. The primary endpoint is a hierarchical composite outcome including escalation of heart failure therapy, persistent congestion at discharge, inability to transition to oral loop diuretics by Day 5, and residual ultrasound congestion. The findings of the SURE-HF trial may support implementation of urinary sodium-guided and ultrasound-assisted decongestive therapy in routine heart failure management.
