Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 80 with a BMI over 30 and documented symptomatic Atrial Fibrillation.

Probably not a fit

Patients who have undergone AFIB ablation within the last 6 months or have planned ablation procedures may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial is a randomized double-blind controlled study focusing on patients with obesity and Atrial Fibrillation (AFIB). Participants with a BMI greater than 30 kg/m2 will be assigned to receive either Tirzepatide or a placebo for 12 months. The study aims to evaluate whether significant weight loss from Tirzepatide can improve the management and symptoms of AFIB. Patients will be monitored for AFIB burden using FDA-approved event monitors, while also receiving standard care for their condition.

Why it matters

Potential benefit: If successful, this treatment could lead to significant weight loss and improved management of Atrial Fibrillation symptoms for patients.

How similar studies have gone: Previous studies have indicated that weight loss can positively impact Atrial Fibrillation management, suggesting potential success for this approach.
