A randomized clinical trial in the United Kingdom is evaluating whether weight loss can improve outcomes for older adults with overweight or obesity and persistent atrial fibrillation (AF). The study tests an eight-month intervention combining a low-calorie diet with behavioral support and compares it with usual care. Researchers assess whether the approach reduces AF-related symptoms and considers safety and effectiveness in this older population.
According to the trial description, participants are older adults living with persistent AF who are also overweight or have obesity. The intervention is designed to help participants achieve weight loss over the course of the study, while behavioral support is provided to facilitate adherence. The trial is reported as conducted from 2018 through 2025, indicating a multi-year effort to enroll, follow, and analyze outcomes.
Overall, the research focuses on whether intentional weight reduction through dietary and behavioral strategies is a beneficial and safe option for older patients with persistent AF, with primary attention on AF-related symptoms and tolerability compared with standard management.
