GH1 and pituitary gland adenoma: Background: Acromegaly, typically caused by growth hormone (GH)-secreting pituitary adenomas, leads to chronic GH and insulin-like growth factor-1 overproduction, resulting in significant cardiovascular complications, including left ventricular (LV) hypertrophy, myocardial fibrosis, diastolic/systolic LV dysfunction, and frequent valvular disease.
