The Influence of Risk Factor Modification on Atrial Fibrillation Outcomes and Their Impact on the Success of Catheter Ablation.
The global prevalence of atrial fibrillation (AF) is growing with a significant increase in AF burden. The pathophysiology of AF is complex and exhibits a strong relationship with modifiable lifestyle AF risk factors, such as physical inactivity, smoking, obesity, and alcohol consumption, as well as co-morbidities, such as hypertension, diabetes mellitus, and cardiovascular disease. Current evidence suggests that cardiac rehabilitation and lifestyle risk factor modification can potentially lower the overall AF burden. Additionally, AF ablation can be an effective treatment for a rhythm control strategy, but reducing AF recurrences post-catheter ablation is paramount. Thus, addressing these modifiable lifestyle risk factors and co-morbidities is critical, as the recent 2024 European Society of Cardiology AF guidance update highlights. A comprehensive approach to treating these risk factors is essential, especially given the rising prevalence of AF. This article provides a state-of-the-art update on the evidence of addressing AF-related risk factors and co-morbidities, particularly in patients undergoing AF ablation.
