Abstract

Home-based exercise training is a promising alternative to conventional supervised training for patients with congenital heart disease (CHD). Even though the beneficial effect of exercise interventions is well established in patients with CHD, knowledge concerning variety and utility of existing programmes is still lacking. Therefore, the aim of this review is to give an overview about existing home-based exercise interventions in patients with CHD. A systematic search was performed in PubMed, Cochrane, Scopus and PEDro (2008–2018) for relevant clinical trials that provided any kind of home-based exercise with patients with CHD. All articles were identified and assessed by two independent reviewers. Seven articles with 346 paediatric CHD (18 months to 16 years) and five articles with 200 adults with CHD (21–41 years) were included. Most studies performed a supervised home-based exercise intervention with children and adolescents exercising at least three times per week with duration of 45 min for 12 weeks. Reported outcome measurements were health-related quality of life and physical activity, but mostly exercise capacity measured as peak oxygen uptake that improved in four studies (1.2%, 7%, 7.7%, 15%; p<0.05), walking distance in two (3.5%, 19.5%, p<0.05,) or walking time (2 min, p=0.003) in one. The dropout rates were high (15%), and compliance to the training programme was not reported in the majority of the studies (58%). Home-based exercise interventions are safe, feasible and a useful alternative to supervised cardiac rehabilitation for all age groups of patients with CHD. Nevertheless, training compliance represents a major challenge.
