Cushing’s disease is a chronic endogenous hypercortisolaemia associated with overproduction of adrenocorticotropic hormone by a pituitary adenoma, leading to multiple systemic complications that significantly increase morbidity and mortality, as well as reduce the quality of life as a result of prolonged tissue exposure to excess cortisol. Hypercortisolaemia in Cushing’s disease is associated with significant functional and constitutional disorders of the entire body. The consequences of chronic hypercortisolaemia include haemodynamic disorders associated with excessive vascular contraction and increased blood pressure, obesity, carbohydrate metabolism disorders, dyslipidaemia, and coagulopathies, which may contribute to significant cardiovascular remodelling. Cardiovascular disorders have a particular impact on long-term prognosis and quality of life in Cushing’s disease. If left untreated, Cushing’s disease significantly increases the cardiovascular risk and limits the treatment options for secondary organ complications. Cardiovascular mortality (myocardial infarction, heart failure, stroke) is several times higher in patients with Cushing’s disease than in the general population. Early diagnosis of the corticotropic pituitary tumour, as well as a thorough morphological and functional cardiovascular assessment seem essential in risk stratification. Normalisation of cortisol levels after combined neurosurgical and/or pharmacological treatment reduces mortality and the risk of cardiovascular and respiratory complications. The aim of this study is to present the complexity of clinical problems in patients with Cushing’s disease, who are in a particular need of interdisciplinary care.
