Phone-based monitoring of heart filling pressure (LVEDP)

A mobile health framework for left ventricular end diastolic pressure diagnostics and monitoring.

NIH-funded research Aventusoft, LLC · NIH-11138551

A smartphone app paired with a small, non-invasive sensor to detect and track the pressure inside the heart’s left ventricle for people with or at risk for heart failure.

What this research studies

You would use an everyday smartphone and a lightweight, non-invasive cardiac sensor that connects to an app to estimate left ventricular end diastolic pressure (LVEDP). The system is being designed to give clinicians and you timely information about heart filling pressures without needing an echo or invasive catheter. The project focuses on making the technology cheap and easy to use at home or in primary care so it can help guide treatment and triage. Testing and development will include building the app, integrating the sensor, and validating measurements against standard clinical methods.

Who could benefit from this research

Good fit: Adults with known or suspected heart failure, symptoms such as shortness of breath, or who are at high risk for elevated LVEDP would be the most likely candidates.

Not a fit: People whose care requires immediate invasive catheter-based measurement in acute settings or whose symptoms are unrelated to ventricular filling pressure may not benefit from this device.

Why it matters

Potential benefit: If successful, this could allow earlier, simpler detection and home monitoring of high heart filling pressures, helping to prevent hospital visits and guide treatment decisions.

How similar studies have performed: Invasive pressure-monitoring devices have shown benefit for some patients, but smartphone-based, non-invasive LVEDP monitoring is a newer approach that is not yet widely proven.
