Tirzepatide on Atrial Fibrillation Recurrence After Catheter Ablation in Patients With Obesity and HFpEF (TEAR-AF-HFpEF)

Detailní popis
Background and Rationale: Obesity and HFpEF are key drivers of AF onset and recurrence. In patients with both conditions, 12-month AF recurrence after catheter ablation reaches 40-55%. The LEGACY and ARREST-AF cohorts demonstrated that ≥10% weight loss approximately halves AF recurrence. Tirzepatide, a dual GIP/GLP-1 receptor agonist, achieved over 20% weight reduction in SURMOUNT-1 and improved heart failure outcomes in the SUMMIT trial of HFpEF with obesity. Whether tirzepatide reduces post-ablation AF recurrence has not been prospectively tested. TEAR-AF-HFpEF enrolls a population most likely to benefit mechanistically - obesity plus HFpEF - and tests the hypothesis with a hemodynamically defined HFpEF cohort.
Study Design: Multicenter randomized open-label parallel-group blinded-endpoint superiority trial. Eligible patients are randomized 1:1 within 48 hours of ablation, stratified by site, AF type (paroxysmal vs persistent), and BMI.
Intervention:
Tirzepatide arm: weekly subcutaneous tirzepatide starting at 2.5 mg/week with monthly 2.5 mg dose escalation to a target of 10 mg/week, advanced to 15 mg/week if tolerated, for 12 months.
Control arm: standard care without GLP-1 class drugs. Both arms receive identical structured lifestyle intervention (≥150 min/week moderate aerobic activity, sleep apnea screening), and standard-of-care guideline-directed therapies for AF, anticoagulation, and HFpEF.
Sample Size and Statistical Approach: A total of 602 participants (301 per arm) provides 80% power at two-sided α = 0.05, assuming 15% loss to follow-up. The primary analysis is an intention-to-treat Kaplan-Meier comparison with log-rank test and Cox proportional hazards modeling stratified by randomization factors.

Experimentální: Tirzepatide + Lifestyle Intervention
Participants receive subcutaneous tirzepatide once weekly for 12 months in addition to guideline-directed lifestyle intervention. Dose escalation: 2.5 mg/week for weeks 1-4; 5 mg/week for weeks 5-8; 7.5 mg/week for weeks 9-12; 10 mg/week from week 13 onward (target); may be escalated to 15 mg/week if tolerated. All participants additionally receive a structured lifestyle intervention identical to the control arm. |
Dual GIP and GLP-1 receptor agonist administered as a weekly subcutaneous injection. Titrated from 2.5 mg/week to a target of 10 mg/week (maximum 15 mg/week) over 12 weeks, then maintained at the maximum tolerated dose for the remainder of the 12-month treatment period.
Ostatní jména:
Guideline-directed AF management (rate/rhythm control, anticoagulation by CHA2DS2-VASc). Guideline-directed HFpEF therapy (MRA, SGLT2 inhibitor as clinically indicated). Structured lifestyle intervention: monthly dietitian-led counseling targeting a 500 kcal/day caloric deficit; exercise prescription of ≥150 min/week moderate aerobic; smoking cessation and alcohol moderation counseling. |

Aktivní komparátor: Lifestyle Intervention
Participants receive guideline-directed standard care for AF, anticoagulation, and HFpEF, without any GLP-1 receptor agonist or GIP/GLP-1 dual agonist. The same structured lifestyle intervention as the experimental arm is delivered, including monthly dietitian-led counseling, exercise prescription, and sleep apnea screening, to ensure equal follow-up intensity. |
