Recommended standards of care do not include the prescription of exercise to target and ameliorate the progressive health decline and overall feeling of well-being in patients with atrial fibrillation. Recent Standards for the Provision of Cardiac Rehabilitation of Ontario are calling for the consideration for referral and enrollment of patients with atrial fibrillation in cardiovascular rehabilitation - evidence is needed to support and confirm these efforts. The main purpose of this project is to evaluate the effects of high-intensity interval training (HIIT) compared to moderate-intensity continuous exercise training (MICE) and standard care on exercise capacity and quality of life in patients with persistent or permanent atrial fibrillation. Positive results from this study will identify a new intervention that: produces important improvements in patient-rated clinical, behavioural and exercise outcomes; provides mechanistic insight into the role of exercise training in the management of atrial fibrillation; requires minimal equipment; and, is appealing to patients with atrial fibrillation.
The main purpose of this project is to evaluate the effects of high-intensity interval training (HIIT) compared to moderate-intensity continuous exercise training (MICE) and standard care on exercise capacity and quality of life in patients with persistent or permanent atrial fibrillation. Positive findings are vitally important for these patients, given the condition's substantial morbidity, mortality and high economic costs.
