Brief Summary

Background and study concept: Atrial fibrillation is the new global epidemic in cardiology. With improved survival from other cardiovascular diseases and longer living in general, the incidence and prevalence of AF rise dramatically in all developed countries with an estimated life time risk of one in four for all people above the age of 40 years. Similarly in Denmark, the prevalence is estimated to almost double within 2020. It is a fatal arrhythmia with doubled mortality compared to patients with normal sinus rhythm; this primarily caused by an increased risk of stroke and heart failure. In particular stroke is a feared complication with a 70% risk of fatal outcome or lasting handicaps and immense costs for each patient as well as in terms of health costs. Moreover, many AF patients experience a variety of symptoms and have markedly reduced quality of life. Opposed to heart failure patients and patients who have suffered from a myocardial infarction, AF patients are not offered any sort of rehabilitation when diagnosed. Pharmacological treatment of the arrhythmia is challenging. Most often, individual and careful risk evaluation including ultrasound of the heart is obligatory to choose optimal treatment strategy and prophylactic anticoagulation. In case a new anti-arrhythmic drug is started to restore and maintain sinus rhythm, hospitalization for at least two days with heart rhythm monitoring is required to detect any possible potentially dangerous or even fatal arrhythmia as a side effect to the treatment. Additionally, the first new oral anti-arrhythmic AF drug introduced for more than twenty-five years proved to be hazardous in a high-risk AF population and is now only used with strict precautions. To explore the role of alternative treatment strategies and to renew handling of cardiac arrhythmia, we have therefore set out to study the role of physical exercise in AF patients. Our specific study aims are to examine:

  1. 1.The effect of physical exercise on AF burden
  2. 2.The effect of physical exercise on the risk of cardiovascular hospitalization

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in burden of atrial fibrillation at 12 weeks measured by tele-ECG i.e. number og ECGs with atrial fibrillation divided by total number of ECGs

    Further assessments: 2 months after end of training.

    Pre-training (baseline) and after 12 weeks of training (primary endpoint)

Secondary Outcomes (1)

  • Change from baseline in hospitalization related to atrial fibrillation at one year after end of training measured by number of admissions/contacts registered in the patients records.

    Pre-training (baseline) and one year after end of training (primary endpoint)

Study Arms (2)

High Intensity Endurance Physical Exercise

EXPERIMENTAL

High Intensity endurance physical exercise, intensity measured on Borg Scale with progression from Borg 10-13 (50% of maximum) to 17-18 (80 % of maximum). One hour of exercise twice weekly for 12 weeks supervised by physiotherapists.

Other: Physical Exercise

Low Intensity Endurance Physical Exercise

ACTIVE COMPARATOR

Low Intensity endurance physical exercise, intensity measured on Borg Scale, Borg 10-13 (50% of maximum) with no progression in intensity. One hour of exercise twice weekly for 12 weeks supervised by physiotherapists.

Other: Physical Exercise

Interventions

Comparison of high versus low intensity physical exercise in patients with atrial fibrillation.
