Summary

Growth hormone (GH) impacts heart development and function. GH replacement therapy can improve cardiac function in conditions like acromegaly, GH deficiency, and idiopathic dilated cardiomyopathy.

Area of Science:

  • Cardiology
  • Endocrinology
  • Molecular Biology

Background:

  • Growth hormone (GH) and insulin-like growth factor-I (IGF-I) play roles in heart development and hypertrophy.
  • Abnormal GH levels are linked to impaired cardiac function, reduced life expectancy, and metabolic changes like hyperlipidemia and atherosclerosis.
  • Acromegalic cardiomyopathy correlates with disease duration, showing myocardial hypertrophy, fibrosis, and infiltration.

Purpose of the Study:

  • To investigate the role of GH in cardiac function and hypertrophy.
  • To evaluate the effects of GH replacement therapy on cardiac parameters in various conditions.
  • To explore the potential of GH in treating idiopathic dilated cardiomyopathy.

Main Methods:

  • Review of clinical manifestations and studies related to GH levels and cardiac function.

  • Analysis of cardiac structure and function in patients with acromegaly and GH deficiency (GHD).
  • Assessment of outcomes following GH replacement therapy and recombinant GH (rGH) administration.

    • Main Results:

    • GH deficiency (GHD) is associated with reduced left ventricular mass (LVM) and ejection fraction (EF).
    • GH replacement therapy improved cardiac function in acromegaly and GHD patients.
    • Recombinant GH (rGH) administration increased myocardial mass and improved hemodynamics in idiopathic dilated cardiomyopathy.

    Conclusions:

    • GH significantly influences cardiac mass and function.
    • GH replacement therapy offers therapeutic benefits for cardiac dysfunction in endocrine disorders.
    • GH holds promise as a treatment for idiopathic dilated cardiomyopathy, enhancing myocardial mass and clinical status.
