Investigating the link between FGF23 and heart rhythm issues in dialysis patients

Fibroblast Growth Factor 23 and Risk of Cardiac Arrhythmias in Hemodialysis Patients: a Proof-of-concept Study (FibCa-HD)

Observational Ente Ospedaliero Cantonale, Bellinzona · NCT06668831

This study is trying to see if levels of a protein called FGF23 are linked to heart rhythm problems in patients who are on dialysis.

What this trial studies

This observational study aims to explore the relationship between fibroblast growth factor 23 (FGF23) levels and cardiac arrhythmias in patients undergoing maintenance hemodialysis. By monitoring changes in FGF23 during dialysis and their association with electrocardiographic abnormalities, particularly QTc prolongation, the study seeks to enhance understanding of the mechanisms that may lead to heart rhythm disturbances in chronic kidney disease patients. The research will be conducted at a single center, focusing on a well-characterized group of hemodialysis patients over a defined period.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who have been on maintenance hemodialysis for at least three months.

Not a fit: Patients with a history of cardiac arrhythmias or those requiring a pacemaker will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for managing cardiac risks in hemodialysis patients.

How similar studies have performed: While the specific approach of linking FGF23 to cardiac arrhythmias in hemodialysis patients is exploratory, previous studies have indicated potential associations between FGF23 and cardiovascular risks.
