Registry to evaluate secretoneurin in predicting atrial fibrillation recurrence

Secretoneurin as a Biomarker of Atrial Fibrillation rEcurrence After Catheter Ablation/Electrical Cardioversion

NA · University Hospital Ostrava · NCT05794464

This study is testing if measuring a substance called secretoneurin in the blood can help predict whether people with atrial fibrillation will have their heart rhythm problems come back after treatment.

What this trial studies

This study aims to assess the levels of secretoneurin (SN) and other biomarkers before and after catheter ablation or electrical cardioversion in patients with atrial fibrillation (Afib). By analyzing these biomarkers, the study seeks to predict the likelihood of Afib recurrence following these interventions. Blood samples will be collected from participants before and after the procedures, and they will be monitored for recurrence using ECG Holter and external loop recorders. The study focuses on understanding the relationship between these biomarkers and Afib outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with paroxysmal or persistent atrial fibrillation who are indicated for catheter ablation or electrical cardioversion.

Not a fit: Patients with longstanding or permanent atrial fibrillation, severe heart or kidney conditions, or recent myocardial infarction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable method for predicting Afib recurrence, potentially improving patient management and outcomes.

How similar studies have performed: While the approach of using biomarkers to predict Afib recurrence is being explored, this specific combination of biomarkers and methodology appears to be novel.
