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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a magnetocardiography (MCG) device can detect reduced blood flow to the heart muscle in people with acute chest pain but no major artery blockages. About 3,786 participants will undergo MCG scanning, and results will be compared to a standard ultrasound test. If accurate, MCG could become a faster, non-invasive tool for diagnosing non-obstructive myocardial ischemia.

What this could mean

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

Active substance
Magnetocardiography device
What this could lead to
If successful, this could provide a non-invasive, quick way to diagnose heart muscle oxygen shortage in patients whose arteries appear normal on standard tests.
What could go wrong
This is an early diagnostic study, not a treatment trial. The device's accuracy may not be high enough to replace current methods, and results may not apply to all chest pain patients.

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 or older; * Patients with symptoms of myocardial ischemia such as angina pectoris, who have CAG showing \<70% stenosis at the most severe site or CTA showing non-severe stenosis * Signed informed consent. Exclusion Criteria: * Patients with absolute or relative contraindications to CFR-loaded myocardial perfusion, including acute myocardial infarction within 48 hours, significant left main coronary artery stenosis, bronchial asthma, and adenosine injection allergy; * Patients with Non-ischemic dilated cardiomyopathy, or hypertrophic cardiomyopathy, or moderate or severe valvular disease; * Patients with Hemodynamic instability (systolic blood pressure\<90 mmHg, or who requires vasoactive drugs), or patients with tachyarrhythmia, #degree atrioventricular block and above that have not returned to normal; * Patients who have severe renal abnormality with eGFR \<30 ml/min, or patients who are on dialysis; * Patients with malignant tumors with predicted survival of less than 1 year; * Pregnant or breastfeeding women; * Patients who are unable to enter the MCG device, who are unable to perform MCG examination due to interference from metal implants or other reasons, or who are deemed by the investigators to be unsuitable for enrollment.
