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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 investigates whether fibromuscular dysplasia (FMD), a condition that causes abnormal growth in artery walls, is more common in people who have had a spontaneous coronary artery dissection (SCAD) — a tear in a heart artery that can cause a heart attack, often in young women without typical risk factors. Researchers will analyze blood samples for genetic markers and use imaging to check for FMD in multiple artery beds. The goal is to confirm the suspected association and uncover genetic determinants that might explain why SCAD happens.

What this could mean

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

Active substance
blood sample for genetic analysis
What this could lead to
If the link is confirmed, it could lead to better screening and earlier detection of SCAD risk in young women.
What could go wrong
This is an observational study, so it won't test a treatment. The findings may not apply to all populations, and the genetic factors may be complex.

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

200 people

The number who actually took part.

Start date

May 2016

Finished

Nov 2019

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

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion Criteria: Inclusion criteria : * Patients over 18 year's old * Patient with a possible diagnosis of spontaneous coronary dissection defined by: * A picture of SCA * Compatible angiographic signs * More or less confirmed by intracoronary imaging (OCT/IVUS) or check angiographic control (upper to 1 month) * Patient having given his informed consent and signed to participate to the study * Subject accepting the use of its personal data in the form of an anonymous codification including in the scientific publications. Exclusion Criteria: * \- Minor patient * Major patient submitted to a protective measure (guardianship, supervision guardianship) * No affiliation to the French social security system * Coronary dissection with traumatic or iatrogenic origin
