Acromegaly is a chronic disease due to growth hormone (GH) and insulin-like growth factor 1 (IGF-1) excess. It is associated with various systemic complications including cardiovascular disease. Arterial hypertension occurs in about 20% to 30% of patients. Its pathogenesis is mainly related to the increase in plasma volume secondary to a sodium retaining actions of GH and IGF-1 in the kidney, but abnormalities in vessel architecture and reactivity participate. Left ventricular hypertrophy and diastolic dysfunctions were frequently reported in echo-based studies and are mostly mild and without clinical consequences. Recent cardiac MRI studies described a much lower frequency of myocardial hypertrophy than echo-based assessments. Progression to systolic dysfunction with congestive heart failure is nowadays very rare. Risk of coronary heart disease and of clinically significant arrythmias does not seem to be increased. Acromegaly-related cardiac valve abnormalities may be related to fibrotic changes and seem to persist after effective treatment of acromegaly. Advances in acromegaly treatment over the last decades significantly diminished the cardiovascular burden of the disease, with the cardiovascular disease anymore being the leading cause of death.
