Summary

Acromegalic heart muscle disease, primarily left ventricular hypertrophy, is reversible. Successful treatment normalizing growth hormone levels leads to slow cardiac hypertrophy regression, confirmed by long-term patient follow-up.

Area of Science:

  • Cardiology
  • Endocrinology
  • Internal Medicine

Background:

  • Acromegalic heart muscle disease is unequivocally recognized.
  • Cardiac hypertrophy, particularly left ventricular hypertrophy, is a major manifestation.
  • Understanding the pattern, nature, and reversibility of this condition is crucial.

Purpose of the Study:

  • To investigate the pattern, nature, and reversibility of acromegalic heart muscle disease.
  • To assess the impact of normalizing growth hormone levels on cardiac hypertrophy.
  • To confirm findings through long-term prospective follow-up.

Main Methods:

  • Retrospective analysis of clinical and echocardiographic data in 78 acromegaly patients.
  • 10-year prospective follow-up of the original patient cohort.
  • Evaluation of treatment with lanreotide, a somatostatin analogue.

Main Results:

  • Cardiac hypertrophy, especially left ventricular hypertrophy, is slowly reversible after growth hormone normalization.
  • Retrospective analysis suggested reversibility.
  • Prospective follow-up confirmed the slow regression of cardiac hypertrophy.
  • Lanreotide treatment led to regression of cardiac hypertrophy.

Conclusions:

  • Acromegalic heart muscle disease is a reversible condition.
  • Normalization of growth hormone levels is key to reversing cardiac hypertrophy.
  • Effective treatment, such as with lanreotide, promotes regression of cardiac hypertrophy.
