Abstract
Hypertension as a sign of other disease is called secondary hypertension. In some cases, early diagnose and treatment may lead to a complete cure or at least to a dramatic improvement of hypertension.
The most typical form of secondary hypertension is endocrine hypertension, in particular primary aldosteronism and less frequently pheochromocytoma, Cushing syndrome or very rarely acromegalia and primary hyperparathyreosis. The other causes are renovascular hypertension, renoparenchymatous hypertension, sleep apnoe syndrome, aortic coarctation or hypertension due to an intracranial tumor.
Suspicion on secondary hypertension should arise when hypertension is resistant to the treatment or when other symptoms or signs typical for diseases associated with hypertension are present, e.g. hypokalemia, paroxysmal symptoms, and sleep disturbances.
