Evaluating inflammation changes in patients after heart rhythm procedure

Change in Inflammatory State in Patients Undergoing Transcatheter Ablation of Atrial Fibrillation

Observational Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico · NCT05961865

This study looks at how inflammation and fat levels change in people aged 18 to 85 after they have a heart procedure to treat atrial fibrillation.

What this trial studies

This observational study aims to assess the relationship between inflammation markers and local fat levels in patients undergoing catheter ablation for atrial fibrillation. It will analyze various inflammation and fibrosis markers, including Interleukin 6 and tumor necrosis factor, at different time points before and after the procedure. The study will include patients aged 18 to 85 who meet specific clinical criteria and can provide informed consent.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 with paroxysmal or persistent atrial fibrillation scheduled for catheter ablation.

Not a fit: Patients over 85 years old, those with severe comorbidities, or contraindications to the procedure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of inflammation's role in atrial fibrillation and improve patient outcomes post-ablation.

How similar studies have performed: Other studies have explored inflammation in relation to atrial fibrillation, suggesting potential for meaningful insights, though this specific approach may be novel.
