Description
Summary:Objectives To assess atrial fibrillation (AF) burden, symptoms and quality of life (QoL) in endurance athletes with paroxysmal AF.Design Prospective cohort study.Setting and participants Otherwise healthy endurance athletes with paroxysmal AF in Norway, Australia and Belgium. The current study presents baseline measurements collected before the intervention of a randomised controlled trial on effects of individually tailored training adaptation.Methods AF burden (percentage time in AF) was measured by insertable cardiac monitors (Confirm Rx, Abbott). AF-related symptoms and QoL were assessed using the Atrial Fibrillation Effect on QualiTy-of-Life Questionnaire (AFEQT) with any score <80 defined as clinically relevant.Results 43 athletes (age 57±10 (mean±SD), range 33–75 years, 3 women) were included. The athletes were monitored for 50±18 days. Median AF burden was 0.18% (IQR 0%–2.6%). Out of 29 athletes with at least one AF episode, 21 (72%) had AF episodes >60 min. 13 athletes (30%) had AFEQT overall score <80, indicating reduced QoL, and 23 athletes (53%) had significant symptoms. AF burden above median, and episodes >60 min were associated with reduced QoL (mean AFEQT score 78 vs 90, p=0.001 and 78 vs 90, p=0.001, respectively). There were large individual variations between the athletes concerning AF burden, symptoms and QoL.Conclusions Although most athletes were still competing, more than half had troublesome symptoms. One-third had reduced QoL, which was associated with higher AF burden and longer duration of AF episodes. Variations between the athletes highlight the need for individually tailored AF management in athletes with paroxysmal AF.Trial registration number NCT04991337.
