Is this trial a fit for you?

Likely a good fit

Ideal candidates are hospitalized patients diagnosed with acute decompensated heart failure who show signs of volume overload and have a compromised response to diuretics.

Probably not a fit

Patients with active deep vein thrombosis, significant coronary artery disease, or those in cardiogenic shock are unlikely to benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study aims to assess the safety and functional performance of the Nephronyx System in patients suffering from acute decompensated heart failure (ADHF) who exhibit signs of volume overload and have a poor response to diuretics. Patients will be monitored for their clinical signs and responses to the Nephronyx system, which is designed to improve fluid management in this population. The study will include hospitalized patients with specific inclusion criteria related to heart function and biomarkers.

Why it matters

Potential benefit: If successful, this treatment could significantly improve fluid management and outcomes for patients with acute heart failure.

How similar studies have gone: While this approach is innovative, similar studies evaluating advanced fluid management systems have shown promise, indicating potential for success.
