NCT ID NCT07204847

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at 407 people with a type of heart attack called NSTEMI to see if getting a heart procedure (coronary angiography) within 24 hours leads to better outcomes. Researchers checked how well following this timing guideline predicted death, another heart attack, stroke, or heart failure at 6 months. The goal was to understand the best timing for this procedure.

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

Inclusion Criteria: * Presence of chest pain with or without ECG changes * Elevation of troponin level \> 90th percentile or a significant increase between two dosages * Significant or non-significant coronary lesion confirming the diagnosis of coronary artery disease on coronary angiography (coronary angiography mandatory before inclusion to confirm NSTEMI) Exclusion Criteria: * STEMI (ST-segment elevation myocardial infarction) or equivalent (defined as chest pain with ECG changes and troponin elevation \> 5 times the normal with an occluded artery (TIMI 0, 1, or 2) during initial coronary angiography) * Very high-risk NSTEMI (hemodynamic instability, cardiogenic shock, recurrent/refractory chest pain despite optimal medical treatment, life-threatening arrhythmia, mechanical complication, heart failure clearly related to NSTEMI, ST depression \> 1mm/6 leads with ST elevation in aVR and/or V1) for which urgent coronary angiography is mandatory * Unstable angina (acute coronary syndrome without troponin elevation) * Troponin elevation without chest pain or symptoms suggestive of NSTEMI * Recovered cardiac arrest * Contraindication to coronary revascularization or coronary angiography * Other diagnoses considered after coronary angiography (e.g., myocarditis, Takotsubo syndrome) * Age \< 18 years
