A thorough clinical evaluation, and not the magnitude of the blood pressure elevation, should be the basis of the differential diagnosis; this will guide the setting required for treatment (intensive care unit, ward or ambulatory), the drugs of choice, as well as the velocity of blood pressure reduction. Special emphasis has to be given to the management of cerebrovascular accidents and severe preeclampsia, as the reduction of blood pressure entails a risk of hypoperfusion of critical territories as the brain and fetus respectively.
