Purpose: The purpose of this study is to evaluate the functional changes of the ventricles for 27 children with recombinant human growth hormone (rhGH) therapy in short stature using echocardiography with tissue Doppler imaging.
Methods: The conventional Doppler echocardiography with tissue Doppler imaging were performed in 27 children with rhGH therapy for short stature and 13 healthy children. Peak velocities of systolic (S) and early (E’), late(A’) diastolic wave of mitral annulus,septum and tricuspid annulus were obtained from apical 4 chamber view.
Results: There was no differences in left ventricle (LV) mass (72.948+/-11.825 m/s2 vs 73.931+/-12.093 m/s2, P=0.08), LV ejection fraction (66.778+/-5.441% vs 70.154+/-6.641%, P=0.095) and LV fractional shortening (36.737+/-4.265% vs 38.085+/-3.419, P=0.327) were observed between patients and controls.There was no significant differences in E and A measured at mitral and tricuspid annulus were observed between pateints and controls. There was no significant differences in S, E’ and A’ measured using tissue doppler imaging at mitral annulus, septum, and tricuspid annulus were observed between patients and controls
Conclusion: No significant differences in parameters of cardiac function using tissue doppler imaging with conventional echocardiography were found between patients with rhGH therapy and controls. But, longer follow-up, involving at a larger number of patients, is required to confirm the safety of long-term rhGH treatment.
