ReDS-Guided Decongestion in Acute Heart Failure (ReDS-LATAM HF) (ReDS-LATAM HF)

2026年5月14日 更新者:Lucrecia Maria Burgos、Instituto Cardiovascular de Buenos Aires

ReDS-LATAM HF: A Randomized Trial of Remote Dielectric Sensing-Guided Decongestion in Acute Heart Failure

Heart failure (HF) is a leading cause of hospitalization, with high rates of early readmission largely driven by residual congestion at discharge. Conventional methods to assess congestion are often imprecise and may fail to guide optimal decongestive therapy.

Remote Dielectric Sensing (ReDS) is a non-invasive technology that provides a rapid and objective estimate of lung fluid content. This study aims to evaluate whether a ReDS-guided decongestion strategy improves clinical outcomes compared with standard care in patients hospitalized for acute heart failure.

In this randomized controlled trial, patients will be assigned 1:1 to a ReDS-guided strategy or standard care. ReDS measurements will be performed in both groups but will only guide treatment in the intervention arm.

The primary endpoint is a composite of all-cause mortality, heart failure rehospitalization, or unplanned HF visit within 30 (±5) days after discharge.

详细说明

Congestion is the main driver of hospitalization and adverse outcomes in acute heart failure (AHF). Residual congestion at discharge is common and associated with increased risk of early rehospitalization and mortality. However, current approaches to assess congestion rely on clinical judgment and indirect markers, which may be insufficient to guide therapy.

Remote Dielectric Sensing (ReDS) is a non-invasive technology that quantifies lung fluid content within seconds. It provides an objective measurement that has been validated against imaging and invasive hemodynamic parameters.

The ReDS-LATAM HF study is a pragmatic, single-center, randomized controlled trial designed to assess whether a ReDS-guided strategy improves early outcomes in patients hospitalized with AHF.

Patients will be randomized 1:1 to either a ReDS-guided strategy, in which daily measurements are used to adjust diuretic therapy according to a predefined protocol, or to standard care based on usual clinical practice. ReDS measurements will be obtained in both groups, but values will be blinded in the control arm.

The primary outcome is a composite of all-cause mortality, heart failure rehospitalization, or unplanned HF visit within 30 (±5) days after discharge. Secondary analyses will include individual components of the primary endpoint, changes in biomarkers, and safety outcomes.

This study also aims to evaluate the feasibility of implementing this technology in a real-world Latin American setting.

实验性的:ReDS-Guided Decongestion Strategy
Participants assigned to this arm will undergo daily Remote Dielectric Sensing (ReDS) measurements during hospitalization. ReDS values will be available to the treating physician and used to guide adjustment of diuretic therapy according to a predefined protocol aimed at achieving effective decongestion while avoiding volume depletion. Treatment decisions, including diuretic dosing and escalation, will be based on ReDS thresholds in combination with clinical judgment. Patients will be discharged based on clinical stability criteria, incorporating ReDS values as part of the decongestion assessment.
Remote Dielectric Sensing (ReDS) is a non-invasive device that estimates lung fluid content by measuring the dielectric properties of thoracic tissues. The system consists of wearable sensors positioned on the anterior and posterior chest, providing a quantitative measurement within approximately 45 seconds. In this study, ReDS measurements will be performed daily during hospitalization. In the intervention arm, results will be available to the treating physician and used to guide diuretic therapy according to predefined thresholds. In the control arm, measurements will be performed but results will remain blinded and will not influence clinical decision-making.
Standard care consists of treatment based on routine clinical assessment, including physical examination, laboratory parameters, and institutional protocols. Diuretic therapy and other treatments will be adjusted according to the treating physician's clinical judgment, without access to ReDS measurements.
