Who could benefit from this research

Could help

Adults with heart failure, including those with tricuspid regurgitation, heart transplantation, or LVAD support, who can undergo venous waveform measurements.

Less likely to help

Patients without heart failure or those unable to participate in non-invasive monitoring may not benefit.

What this research studies

This project refines an AI-powered NIVAHF device that reads venous waveforms to estimate heart-failure–related volume status. It builds on prior work to improve accuracy, especially in patients with tricuspid regurgitation, heart transplants, or LVAD support. The study aims to optimize the AI algorithm, reduce errors, and validate the NIVA score as a surrogate for traditional hemodynamic measurements. Participants would contribute data from venous waveform measurements to help tailor treatment decisions.

Why it matters

Potential benefit: If successful, patients with heart failure could receive more precise, non-invasive monitoring to guide treatment and prevent complications.

How similar studies have gone: Previous NIVAHF research showed promise in non-invasively estimating pressure-related status using AI, with ongoing optimization.
