Acromegaly-induced dilated cardiomyopathy presenting with heart failure as the cardinal symptom: A case report

Acromegaly is a rare endocrine disorder caused by excessive secretion of growth hormone, resulting in elevated serum levels of hepatic insulin-like growth factor-1 (IGF-1). With an estimated annual incidence of approximately three cases per million individuals, the condition is associated with a significantly increased risk of cardiovascular complications, such as arrhythmias and acromegaly-induced cardiomyopathy. Heart failure secondary to acromegalic cardiomyopathy occurs in approximately 3% of affected patients and is recognized as the leading cause of mortality in individuals with this condition. This case report describes a 53-year-old male diagnosed with acromegalic cardiomyopathy caused by a pituitary adenoma.
