New research led by scientists from the University of Colorado (CU) Anschutz (Aurora, USA) suggests that staying physically active after heart rhythm treatment may significantly reduce the risk of atrial fibrillation (AF) returning, offering patients a simple, low-cost way to support their long-term cardiac health.
The study—published recently in the Journal of Interventional Cardiac Electrophysiology—found that adults who engaged in regular, moderate physical activity after undergoing a catheter ablation procedure had markedly lower rates of AF recurrence compared to those who were less active.
“Atrial fibrillation often comes back even after a technically successful ablation, which can be frustrating for patients and clinicians alike,” said Lohit Garg (CU Anschutz School of Medicine, Aurora, USA), lead author of the study. “Our findings suggest that moderate exercise for 30 minutes, three times a week—something most people can realistically do—may help protect against recurrence after undergoing catheter ablation.”
The researchers analysed data from 163 adults who underwent catheter ablation, and tracked both their physical activity levels using wearables and heart rhythm outcomes over time.
In the study, patients who completed at least 90 minutes of moderate physical activity per week—as recommended by the American Heart Association (AHA)—including brisk walking, cycling, swimming or yard work, were significantly less likely to experience a return of AF. Overall, after adjusting for age, medications, heart structure and other clinical factors, moderate weekly exercise was associated with a near-50% reduction in the risk of AF recurrence. The researchers also note that as little as 15 minutes of activity on most days of the week met the threshold linked to improved outcomes.
“For many patients, recovery after ablation raises questions about what they can do beyond medications or procedures to reduce the chances of recurrent AF,” Garg commented. “This study suggests that physical activity may directly support the durability of AF treatment.”
The researchers observed regular physical activity as being associated with better blood pressure control as well as improved sleep, mood and weight management, all of which are known contributors to heart rhythm stability.
“Exercise should be part of the post-ablation conversation,” Garg added. “It’s one of the few interventions patients can control themselves that may meaningfully affect their long-term recovery.”
In addition, the study’s authors emphasise that patients should always consult their healthcare provider before beginning or changing an exercise routine—particularly following a heart procedure.
