High Intensity Interval Training for Congenital Heart Disease
Trial Summary
What is the purpose of this trial?
Congenital heart disease (CHD), the most common birth defect, is present in nearly 1% of the population. CHD patients are associated with intense resource utilization and premature death in adulthood. The risk of premature death is linked with reduced exercise capacity, a finding consistently noted in youth with CHD. Reduced exercise capacity in this population has also been associated with reduce physical activity and health-related quality of life. Cardiac rehabilitation (CR) in adults with acquired heart disease is an established secondary prevention strategy that improves exercise capacity. The investigators propose a prospective clinical trial of a home-based high intensity interval training (HIIT) program using a novel telemedicine-equipped video game-linked cycle ergometer (MedBIKE™) for 10 to 18 year olds with repaired moderate-complex CHD. The pilot study with the MedBIKE has shown promising results. The investigators now seek to study the efficacy of this program in a broader CHD population.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What data supports the effectiveness of the treatment MedBIKE HIIT for congenital heart disease?
High-intensity interval training (HIIT) has been shown to improve aerobic fitness and cardiovascular function in patients with coronary heart disease, suggesting it could also benefit those with congenital heart disease. Additionally, home-based telemedicine exercise interventions, like MedBIKE HIIT, offer improved access and convenience, which is important for patients who live far from specialized care centers.12345
Is high-intensity interval training (HIIT) safe for people with congenital heart disease?
Research shows that high-intensity interval training (HIIT) is generally safe for people with cardiovascular conditions, including congenital heart disease. A systematic review found a low rate of major adverse events during HIIT sessions, suggesting it can be a safe exercise option when properly supervised.12678
How is MedBIKE HIIT different from other treatments for congenital heart disease?
MedBIKE HIIT is unique because it uses high-intensity interval training (short bursts of intense exercise followed by rest) combined with a video game-linked cycle ergometer, making it a fun and engaging home-based exercise option for children with congenital heart disease. This approach is novel as it incorporates telemedicine, allowing real-time monitoring and guidance, which is particularly beneficial for patients who live far from specialized care centers.124910
Eligibility Criteria
This trial is for children and teens aged 10-18 with repaired moderate-complex congenital heart disease. They must speak English, have space at home for the MedBIKE system, and not be restricted from exercising by their cardiologist. Those with severe symptoms, cognitive impairments affecting communication, or recent serious arrhythmias cannot participate.Inclusion Criteria
