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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether a special CT scan (CT-FFR) can help doctors predict heart attacks and other serious events in people with chronic coronary syndrome. About 3,000 participants in China will be followed for up to 5 years. The goal is to see if abnormal CT-FFR results are linked to higher risks, potentially guiding treatment without invasive procedures.

What this could mean

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

What this could lead to
If successful, this could show that a simple CT scan can replace invasive tests to guide treatment decisions for chronic coronary syndrome.
What could go wrong
This is an observational study, not a treatment trial. It will not prove that CT-FFR improves outcomes, only that it may be linked to risk.

Who can take part

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

Who is studied

The study population consists of patients with chronic coronary syndrome (CCS) who undergo coronary computed tomography angiography (CCTA) and CT-derived fractional flow reserve (CT-FFR) evaluation as part of their routine clinical care. Participants are consecutively recruited from multiple tertiary medical centers across China to ensure a representative real-world cohort. This population reflects the broad clinical spectrum of CCS patients encountered in actual practice, encompassing a wide range of coronary disease severity as assessed by non-invasive functional imaging.

Inclusion Criteria: * Age ≥ 18 years. * Clinical diagnosis of chronic coronary syndrome (CCS). * Completed coronary computed tomography angiography (CCTA) examination and successfully obtained CT-derived fractional flow reserve (CT-FFR) results. * The subject or their legal representative voluntarily participates in this study and has signed the written informed consent form. Exclusion Criteria: * Acute coronary syndrome (ACS), including ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), or acute episodes of unstable angina. * Unable to obtain valid CT-FFR results, or the image quality is insufficient to support analysis. * Pregnant patients or those who intend to become pregnant during the study period. * Non-cardiac comorbidities indicating a life expectancy of less than one year. * Failure to sign the informed consent form. * Inability to complete the follow-up or explicit refusal to participate in the follow-up. * Patients with cognitive impairment or psychiatric disorders confirmed by clinical diagnosis or investigator assessment. * Patients who are illiterate or semi-literate, or who, due to any visual impairment or reading/writing disability, are unable to independently read the subject information sheet without assistance and are unable to personally provide written informed consent. * Any other conditions deemed unsuitable for participation in this study by the investigators
