Gut check: could your microbiome predict heart attack outcomes?

NCT ID NCT03439592

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 Results may not be published yet.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

Summary

This study looked at the gut bacteria of 200 heart attack patients, comparing those with high blood sugar to those with normal levels. Researchers collected stool samples before treatment and again at 6 and 12 months to see if changes in gut bacteria relate to survival. The goal is to understand why some patients do worse after a heart attack.

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 help identify patients at higher risk after a heart attack based on their gut bacteria.
What could go wrong
This is an observational study, not a treatment trial. It only looks for patterns, so it cannot prove cause and effect.
