What this trial studies

MOVE-AF is a randomized, open-label trial enrolling 158 overweight or obese adults with symptomatic paroxysmal or persistent atrial fibrillation who are randomized 1:1 to a 12-month tailored exercise and dietary lifestyle intervention plus usual care or to usual care alone. The intervention combines individualized guideline-based aerobic and resistance exercise with dietary counseling aimed at reducing body fat. AF burden will be measured with continuous ambulatory rhythm monitoring and symptom severity with validated questionnaires, while cardiac and total body fat are quantified by cardiac MRI and body composition analysis. Secondary outcomes include cardiorespiratory fitness, muscle strength, cardiac autonomic function, cardiac remodeling, healthcare utilization, and cost-effectiveness.

Who should consider this trial

Good fit: Ideal candidates are adults 18–75 years old with BMI ≥27 kg/m², documented paroxysmal or persistent AF, the ability to participate in exercise training, and access to a smartphone for rhythm monitoring.

Not a fit: Patients with permanent AF, severe cardiac or pulmonary disease, major cognitive impairment, active malignancy, or other contraindications to exercise or dietary modification are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the program could reduce AF episode frequency and symptoms, decrease cardiac and total body fat, and improve fitness and quality of life.

How similar studies have performed: Prior observational studies and some smaller trials show that weight loss and structured lifestyle programs can reduce AF burden and symptoms, but long-term randomized trials with continuous monitoring and cardiac MRI are limited.
