NCT ID NCT07496775

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study is testing a new digital stethoscope that listens for subtle changes in heart sounds to detect coronary artery disease and valve problems earlier. Researchers will record heart sounds from 500 adults who are already scheduled for heart scans or echocardiograms. The goal is to see if this simple, non-invasive device could one day be used in GP surgeries to spot heart disease sooner.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
digital stethoscope device
What this could lead to
If successful, this could lead to a simple, non-invasive way to detect heart disease earlier in GP surgeries, potentially speeding up treatment.
What could go wrong
This is an early-stage study that only collects sounds from people already scheduled for scans. It does not yet test if the device works in real-world settings or improves outcomes.
