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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 300 adults hospitalized with heart failure to see if iron deficiency (with or without anemia) is linked to abnormal heart rhythms or ECG changes. Researchers will measure iron levels and monitor for arrhythmias like atrial fibrillation or ventricular tachycardia during the hospital stay. The goal is to find simple markers that could help identify high-risk patients, especially where advanced iron treatments are not easily available.

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 doctors identify heart failure patients at higher risk for dangerous heart rhythm problems based on simple iron tests.
What could go wrong
This is an observational study, not a treatment trial. It will only show links, not prove cause and effect, and results may not apply to all heart failure patients.

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

Inclusion Criteria: Adult patients (≥18 years) admitted to Assiut University Heart Hospital with a clinical diagnosis of heart failure (new-onset or decompensated). Includes all ejection fraction categories (HFrEF, HFmrEF, and HFpEF). Availability of 12-lead ECG, serum iron studies (ferritin, transferrin saturation, serum iron), and routine laboratory tests. Willingness to participate and provide informed consent. Exclusion Criteria: Known history of primary electrical disorders (e.g., Brugada syndrome, Long QT syndrome, etc.). Recent intravenous iron therapy or blood transfusion within the past 3 months. End-stage renal disease requiring dialysis. Known anemia due to non-iron-deficiency causes (e.g., hemolytic anemia, active malignancy, etc.). Severe electrolyte imbalances (e.g., significant hypo-/hyperkalemia, hypo-/hypermagnesemia). Active systemic infection, chronic inflammatory conditions, or recent chemotherapy. severe valvular lesions
