ReDS-SAFE HF II Trial Launches in Spain to Evaluate ReDS-Guided Management in Hospitalized Heart Failure Patients
The ReDS-SAFE HF II Trial, a large multicenter, investigator-initiated randomized controlled study, has officially begun in Spain.
Funded by the Instituto de Salud Carlos III and the Spanish Society of Cardiology, the trial will further evaluate whether ReDS-guided congestion management can improve outcomes in patients hospitalized with heart failure and during early post-discharge follow-up.
Trial scope and enrollment
ReDS-SAFE HF II plans to enroll more than 1,000 patients across 25 clinical sites in Spain.
Enrollment has started at leading hospitals in:
Madrid
Hospital Universitario Ramón y Cajal
Hospital Universitario Puerta de Hierro
Barcelona
Hospital del Mar
Hospital Moisès Broggi
The study is led by Dr. Jesús Álvarez-García, Head of the Advanced Heart Failure Unit at Ramón y Cajal University Hospital.
What the trial will evaluate?
The trial will assess whether ReDS-guided management during hospitalization and early outpatient follow-up can:
Reduce 30-day mortality
Lower heart failure rehospitalizations
Decrease unplanned heart-failure-related visits
These outcomes will be compared with standard of care.
How ReDS-guided management works
Patients in the ReDS-guided arm will receive:
Daily ReDS measurements during hospitalization
An additional ReDS assessment at early outpatient follow-up
This approach provides objective, quantitative pulmonary congestion data, helping clinicians fine-tune therapy during a high-risk transition period.
Why objective congestion measurement matters?
Residual pulmonary congestion is often missed using standard clinical assessment alone. Dr. Álvarez-García noted that daily objective pulmonary data may help ensure patients are truly optimized before discharge, with the aim of breaking the cycle of early readmissions.
Building on strong prior evidence
ReDS-SAFE HF II builds on results from the original ReDS-SAFE HF study, published in JACC: Heart Failure.
That study reported:
90.6% reduction in the composite endpoint of
30-day mortality
Heart failure rehospitalization
Unplanned visits
Hazard ratio:0.094
p-value: 0.003
The findings supported the clinical value of non-invasive, quantitative lung fluid assessment in hospitalized heart failure patients.
