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
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 Results may not be published yet.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 This study
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 aimed to validate several blood biomarkers (like NT-proBNP and IL-6) to help doctors assess atrial fibrillation burden and track treatment effectiveness. Researchers planned to analyze samples from 266 patients before and after treatment. However, the study was withdrawn before any participants were enrolled, so no new insights were gained.

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 research could help doctors use blood tests to better track atrial fibrillation and predict heart failure progression.
What could go wrong
The study was withdrawn before enrolling any participants, so no results are available. The findings may not apply to all patients with atrial fibrillation.

Who is studied

This study is a follow-up to the prospective generational study (AFTTER: Atrial Fibrillation Trial To Eliminate Risk-factors; NCT05718336) that enrolled patients from 2020 to 2023. After consenting to participate in this study, patients underwent a series of questionnaires, blood tests, and special examinations (see the figure below). The caregiver (the arrhythmia treatment team at National Taiwan University Hospital) formulated a treatment plan based on the examination results. After approximately two years (at least one year) of treatment, a post-test was conducted to conclude the study (a total of 343 patients were enrolled in this study, of which 266 participants completed the pre- and post-treatment tests and blood tests).
