Exercise and Dietary Lifestyle Intervention on Reducing Atrial Fibrillation Burden, Cardiac and Body Fat Mass.

Recruiting now · Not applicable

Conditions studied: Atrial Fibrillation (AF), Obesity & Overweight

In brief

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is strongly associated with obesity and excess body fat. Lifestyle interventions, including exercise and dietary modification, may reduce AF burden, but long-term randomized controlled trial evidence with objective AF burden assessment and advanced cardiac imaging is limited. The MOVE-AF trial is a randomized controlled trial designed to evaluate whether a 12-month tailored exercise and dietary lifestyle intervention, compared with usual care, reduces atrial fibrillation burden and symptom severity and decreases cardiac and total body fat mass in overweight and obese adults with paroxysmal or persistent AF.
