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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will test whether an artificial intelligence (AI) system can detect pulmonary hypertension and other heart diseases using a smart stethoscope. Researchers will collect heart sound and ECG recordings from 1,000 adults already scheduled for routine echocardiography. The goal is to see if the AI can accurately identify heart problems compared to standard ultrasound imaging. If it works, this could lead to a simple, non-invasive screening tool for early detection.

What this could mean

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

Active substance
AI-powered smart stethoscope (device)
What this could lead to
If successful, this could lead to a non-invasive, AI-driven tool for early detection of pulmonary hypertension and other heart conditions, potentially improving diagnosis and outcomes.
What could go wrong
This is an early validation study, not a treatment trial. The AI algorithms may not perform as well in real-world settings as hoped, and the results may not apply to all patient groups.
