The Norwegian Exercise in Atrial Fibrillation Trial
Sponsor: Norwegian University of Science and Technology
Summary
Atrial fibrillation (AF) patients suffer a high symptom burden and reduced quality of life (QoL), high hospitalization rates and few effective treatment options. They have a high burden of cardiovascular risk factors and events. Lifestyle changes and exercise is a cornerstone of management in most chronic cardiac conditions and holds promise in AF, but the evidence is sparse and specific guidelines for exercise do not exist for AF patients. NEXAF is a large-scale multicenter randomized trial to determine the feasibility and effects of exercise on patient-reported and clinical outcomes. All patients will undergo continuous rhythm monitoring, enabling assessment of duration, frequency and total time of AF episodes. The overall aim of the study is to provide documentation for clinical exercise recommendations in AF. The objectives are to examine the effects of a 1-year exercise intervention in AF patients on (i) QoL and symptom burden, (ii) time-in-AF, and peak oxygen uptake, cardiac structure and function, cardiovascular risk factors and use of healthcare resources.

Conditions
Interventions
Supervised home-based exercise
150-300 minutes of moderate intensity activity (55-75% of maximum heart rate in sinus rhythm or RPE 12-13 on the Borg Scale) or 75-150 minutes of vigorous intensity activity (75-90% of maximum heart rate or 14-16 on the Borg Scale) per week, or an equivalent combination of both, according to current general recommendations, including also those with established CVD. To maximize the potential for improvements in cardiorespiratory fitness, we encourage that at least 40-60 minutes per week (i.e. 2 sessions á 20-30 minutes) should be of vigorous intensity.
Usual care
Standard management according to usual practice at the respective participating centers, including medical therapy as per guidelines. Prior to randomization all will be provided an ICM (Confirm RX™). The UC group will receive information about general PA recommendations as per guidelines at study enrollment. No further supervision is given.
