Dissertation Project Title: Effects of a Mindfulness-Based Intervention in Chronic Heart Failure

Patients with Chronic Heart Failure diagnosed and conventional treated, but still symptomatic (i.e. breathlessness, fatigue) is invited. Eligible patients are randomised to (1) care as usual (i.e. optimized medical treatment) or (2) care as usual (i.e. optimized medical treatment) in combination with an 8-week mindfulness-based educational and training program. Specific research questions: * How are self-reported symptoms of breathlessness, fatigue, difficult sleeping, anxiety and depression affected by a mindfulness-based educational and training program (MBI)? * Does the implementation of an 8-week Mindfulness-based program have any impact on personal experiences of well-being and health? * What effects does an 8-week MBI have on objective signs of importance for the progression of heart failure?
