AI reads ECGs to stop heart failure before it starts

NCT ID NCT07355023

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 uses artificial intelligence to analyze electrocardiograms (ECGs) and identify people at high risk for developing left ventricular dysfunction, a type of heart muscle weakness. Researchers will then see if giving standard heart medications—like ACE inhibitors, beta-blockers, and SGLT2 inhibitors—can lower that risk. The study involves 5,000 participants and uses existing medical records to simulate a clinical trial.

What this could mean

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

Active substance
guideline-directed medical therapies (ACE inhibitors, ARBs, beta-blockers, SGLT2 inhibitors)
What this could lead to
If successful, this could show that AI-powered ECG screening plus early medication can prevent heart failure in at-risk people.
What could go wrong
This is a retrospective study, not a randomized trial, so results may be less reliable. It also relies on existing medical records, which can have missing or inconsistent data.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 5,000 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jan 2026

An estimate. Start dates often move.

Expected to finish

Jan 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * With an ECG followed by an echocardiogram within a 90-day interval * With preserved left ventricular ejection fraction (LVEF ≥ 50%) Exclusion Criteria: * missing essential variables or ECG lead data * any prior LVEF \< 50% * loss to follow-up or death during the 90-day assessment window
