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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether a simple bedside heart ultrasound measurement, called the S' wave, can help emergency doctors quickly identify acute coronary syndrome (heart attack or unstable angina) in patients with chest pain. Researchers enrolled 66 adults who came to the ER with chest pain but no clear signs of a major heart attack on their initial ECG. They compared the S' wave results with the final diagnosis made after 3 months of follow-up. The goal is to see if this quick test can improve early detection and speed up life-saving care.

What this could mean

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

Active substance
Tissue Doppler Imaging (TDI) S' Wave Echocardiography
What this could lead to
If successful, this could give ER doctors a fast, bedside tool to spot heart attacks earlier, potentially speeding up treatment.
What could go wrong
This is a small, completed observational study (66 people). The S' wave may not prove accurate enough in larger, more diverse groups, and results may not change current practice.

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

66 people

The number who actually took part.

Started

Finished

Mar 2026

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: * Age ≥18 years * Presenting to the emergency department (ED) with acute chest pain * No ST-elevation myocardial infarction (STEMI) on initial ECG * Requiring continuous cardiac monitoring based on triage decision * Able to provide informed consent (written consent required) Exclusion Criteria: * Known pre-existing cardiomyopathy (e.g., hypertrophic cardiomyopathy, dilated cardiomyopathy) * Severe valvular heart disease * Left bundle branch block (LBBB) or presence of a pacemaker * Arrhythmias (e.g., atrial fibrillation, frequent premature ventricular contractions) * Cardiac arrest or cardiogenic shock at presentation * Pulmonary hypertension * Pericardial effusion or tamponade * Non-cardiac cause of chest pain suspected as the primary diagnosis * Language barrier preventing informed consent (study materials available in English, French, and Dutch)
