Cost-effectiveness of exercise training in older patients with heart failure
Whilst exercise training is known to be beneficial in younger people with heart failure, this evidence is not applicable to typical patients who are older. Furthermore, there is little evidence available on the cost-effectiveness of exercise training in older heart-failure patients. A 112-patient, two-arm, randomised trial was conducted to evaluate the effectiveness and cost-effectiveness of exercise training in older patients with heart failure. The exercise training programme consisted of eight weeks of twice–weekly, therapist-led, supervised small-group intermittent functional aerobic exercise and strength training, with the duration of sessions gradually increased to 60 minutes. This was followed by a 16-week, home-based exercise phase which included self-monitoring and telephone instruction and encouragement from the therapist. The results showed that the exercise training was neither effective nor cost-effective. Heart failure predominantly affects people aged over 70 years of age.
Outcome and Translation
The exercise intervention did not improve exercise capacity or quality of life in older patients with heart failure. There was no evidence of cost savings to the NHS. Therefore, this study does not support the adoption of exercise training for older heart-failure patients. The findings are of interest to cardiologists, cardiac rehabilitation workers and practitioners of medicine for older people.
