Detailed Description
Guidelines recommend physical training in the treatment of patients with CHF. Several studies have demonstrated that even short-term training programmes can increase maximal oxygen intake, improve muscular strength, reduce neurohumoral activity and result in other effects, which are of potential benefit. Following 2-3 months training at 70 - 80% of maximal capacity, improved exercise capacity and oxygen uptake due to increased cardiac output and also better oxygen uptake in the peripheral muscles have been demonstrated. Moreover, studies have indicated an improvement of the quality of life (QOL). However, the effects of exercise training are rapidly lost without maintenance. Thus the crucial question is to identify a method to sustain the physical activity outside an expensive, enthusiastic and highly motivating protocol.
The aim of the study is to determine whether a low-cost home-based training programme can maintain the achieved effect of physical training on exercise capacity and QOL in patients with Chronic Heart Failure.
Comparison:
Patients fulfilling specified criteria for Chronic Heart Failure are randomised to either eight weeks with supervised group-based training (1.5 hrs.) twice a week followed by home-based training according to a specified protocol with supervised group-based training every 2 weeks (1,5 hrs), or to eight weeks with supervised training followed by usual care. During the whole period patients in both groups can contact the Heart Failure Clinic when needed.

- Optimal medical treatment according to guidelines
- Informed consent -
Exclusion Criteria:
- Hæmodynamically significant obstructive heart valve disease
- Hæmodynamically significant valve insufficiency
- Recent Myocardial infarction (8 weeks)
- Significant arrythmia at exercise testing (NSVT, VT, VF or SVT with ventricular action >150)
