Cardiac and aerobic response to growth hormone therapy in children with short stature: a prospective study using VO2max and speckle tracking echocardiography
Cardiovascular and aerobic outcomes following growth hormone treatment in short-statured children
Overview
This study evaluated the effects of recombinant human growth hormone (r-hGH) on aerobic capacity and cardiac function in prepubertal children with short stature. While r-hGH therapy improved cardiac remodeling, no overall enhancement in aerobic capacity was observed over one year.
Background
Recombinant human growth hormone (r-hGH) is used to promote growth in children with growth hormone deficiency (GHD) and other short stature conditions. Understanding its impact on aerobic capacity and cardiac function is crucial, as these factors can influence long-term health outcomes. This study aims to clarify the relationship between r-hGH therapy and these parameters in a pediatric population.

Key Findings
r-hGH significantly increased IGF-1 and left ventricular mass indices.
VO2max showed no overall improvement; a significant decrease was observed in GHD children, particularly girls.
Only GHD males exhibited supranormal VO2max values at baseline, which persisted at 12 months.
GLSR improved significantly at 6 months in GHD patients, indicating early myocardial response to GH therapy.
No correlation was found between VO2max evolution and cardiac parameters.
Clinical Implications
The findings suggest that while r-hGH therapy may lead to favorable cardiac remodeling, it does not necessarily enhance aerobic capacity in short-statured children. Clinicians should monitor both cardiac function and aerobic performance during r-hGH therapy.
Conclusion
Revise to strictly summarize the study's findings without additional implications.
