Abstract 10548: Atrial Fibrillation Worsens Sports Performance in Athletes; Greatest Improvement Seen With Ablation: A Stopafib.org Survey

Abstract

Introduction: Anecdotally, both atrial fibrillation (AF) and medications for AF, are poorly tolerated in athletes. However, data are lacking. Methods: An internet-based survey, initiated via StopAfib.org, queried the impact of AF and treatment modalities on sports performance, training, and well-being. Performance, (rated in comparison to personal best), frequency of training and competition were categorized ordinally and compared prior to onset of AF symptoms versus when symptoms at worst, via paired Wilcoxon, and then compared in relation to participants’ AF treatments. Results: Between 5/13/19 and 2/29/20, 802 athletes responded, including 78% males, 22% female, median age 61 to 70 years . The most reported sports were cycling (25%) and running (20%). Median time since diagnosis was 3 to 5 years. When participants’ symptomatology was at worst, the median frequency was at least once a week, most commonly palpitations, fatigue, and decreased exercise tolerance. Development of AF was associated with declining sports performance, competition, and training frequency as shown in the table below. Of 471 participants who decreased their exercise regimen, 31% reported no change in symptoms, 56% reported a decreased frequency of AF, and 13% reported no further AF. Among athletes that received treatment, ablation was associated with the greatest improvement in sports performance compared with ablation plus medications or medications alone (see table below). Of 262 athletes currently on medication, 27% reported that it was completely effective, 58% partially effective, and 15% not effective. Of 653 athletes that have taken medication currently and/or in the past, 43% reported side effects, most commonly fatigue, low energy, or decreased athletic performance. Conclusions: In athletes, AF was associated with decline in sports performance. Among AF treatment modalities, ablation was associated with the greatest improvement in sports performance.
