ESC 23 — Dr Jesus Alvarez-Garcia (Ramon and Cajal University Hospital, ES) considers the use of ReDS technology in patients with acute heart failure (ReDS-SAFE HF) (NCT04305717) in this short interview.

The ReDS-SAFE HF study (Icahn School of Medicine at Mount Sinai) aimed to test the remote dielectric sensing (ReDS) system, a novel electromagnetic technology that can noninvasively quantify changes in lung fluid concentration. This study aims to test if a ReDS-guided strategy during heart failure admission is superior to standard care during a 1-month follow-up. 240 patients with acutely decompensated heart failure will be randomized to receive either standard of care strategy, or ReDS-guided strategy. 

Results suggest that the ReDS-guided strategy significantly reduced the primary outcome with a hazard ratio of 0.094. Quality of life was also shown to be improved in the ReDS-guided arm.

Questions:

1. What is the importance of this study?
2. Please outline the ReDS system.
3. What was the study design, eligibility criteria and outcome measures?
4. What are the late-breaking findings?
5. How should these findings impact practice?
6. What are the foreseeable challenges in incorporating this into patient care?
7. What are the next steps?
