Contraindications to tirzepatide or GLP-1\u002FGIP receptor agonists (e.g., prior serious hypersensitivity, personal or family history of medullary thyroid carcinoma or MEN2, history of clinically significant pancreatitis, severe gastrointestinal disease that may impair tolerance or absorption).\n9. Poorly controlled type 1 diabetes, recent diabetic ketoacidosis, end-stage renal disease requiring dialysis, or severe hepatic dysfunction judged clinically significant.\n10.

It will also evaluate the effects of tirzepatide on body weight, metabolic risk factors, and clinical outcomes, as well as its safety and tolerability in this population.\n\nThe main questions it aims to answer are:\n\n1. Does peri-procedural treatment with tirzepatide reduce AF burden at 3 months after de novo catheter ablation, as measured by 7-day continuous ECG patch monitoring?\n2. Does tirzepatide lead to greater weight loss and improvement in metabolic parameters compared with standard care alone?\n3. Does tirzepatide reduce AF recurrence and cardiovascular events during 12 months of follow-up? Researchers will conduct a multi-center, open-label, endpoint-blinded, randomized controlled trial in adults aged 18-80 years with persistent AF and body mass index ≥25 kg\u002Fm² who are scheduled for de novo catheter ablation. Participants will be randomized 1:1 to receive either tirzepatide plus standard peri-procedural and post-ablation care or standard care alone.\n\nParticipants in the tirzepatide group will receive subcutaneous tirzepatide 2.5 mg once weekly starting about 4 weeks before ablation and continuing for 3 months afterward, for a total treatment duration of approximately 4 months. All participants will be followed at 1, 2, 3, 6, and 12 months after ablation, with detailed assessment of AF burden, AF recurrence, echocardiographic parameters, metabolic profile, quality of life by the AFEQT questionnaire, and safety events.",[70,71,72],"Atrial Fibrillation Ablation","Persistent Atrial Fibrillation","Obesity & Overweight",[74,75,21,76,77,78,79],"Atrial fibrillation","Catheter ablation","Overweight and obesity","AF burden","Recurrence","Quality of life","NOT_YET_RECRUITING","2026-06-10",{"date":83,"type":84},"2026-06-12","ACTUAL",{"date":86,"type":64},"2026-06-16",{"date":88,"type":64},"2028-07-31",{"name":5,"class":6},1]
