About this trial

Obese patients with atrial fibrillation (AF) have a high recurrence rate after catheter ablation, even at experienced centers. Weight reduction improves post-ablation outcomes, but lifestyle measures alone are difficult to sustain. Tirzepatide, a once-weekly GIP/GLP-1 dual receptor agonist, produces greater weight loss than GLP-1 monotherapy and may confer additional cardiometabolic benefits. This multicenter, randomized, open-label, parallel-group, superiority trial evaluates whether adding standardized tirzepatide treatment to a structured lifestyle intervention - compared with the lifestyle intervention alone - reduces AF recurrence within 1 year after ablation in obese patients.

Eligibility criteria

Qualifiers

Age ≥18 years and ≤75 years at the time of screening

Documented symptomatic paroxysmal AF or persistent AF, confirmed by 12-lead ECG, Holter monitoring, or cardiac monitoring device, with documented AF episode duration ≥7 days (for persistent AF) and total AF history duration ≤5 years

Failed response to or intolerance of at least one antiarrhythmic drug (AAD), or explicit patient preference for a rhythm control strategy

Undergoing catheter ablation for AF at a participating center, with confirmed successful restoration of sinus rhythm at the end of the procedure (as determined by the operator)

Disqualifiers

Long-standing persistent AF: continuous AF duration ≥5 years prior to enrollment

Prior catheter ablation for AF or atrial flutter at any time

Left atrial anteroposterior diameter >55 mm (by transthoracic echocardiography at screening)

Left ventricular ejection fraction (LVEF) <35% at screening
