Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are children and teenagers aged 8-18 with pulmonary hypertension classified as WHO functional class I or II.
✕Probably not a fit
Patients with more severe functional class III or IV pulmonary hypertension or those with significant comorbidities may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This intervention focuses on increasing physical activity in children and teenagers aged 8-18 with pulmonary hypertension (PH) through a 16-week exercise program. Utilizing wearable activity monitoring devices, the study aims to promote exercise and improve skeletal muscle mass, which is often deficient in this population. The program targets children with WHO functional class I or II PH, who are ambulatory and have stable medication regimens. By addressing exercise intolerance, the study seeks to enhance both exercise performance and quality of life for these young patients.
Why it matters
Potential benefit: If successful, this program could significantly improve exercise performance and overall quality of life for children with pulmonary hypertension.
How similar studies have gone: Recent trials have shown success in improving exercise performance in adults with pulmonary hypertension through prescribed exercise training, suggesting potential for similar benefits in pediatric populations.
