Hypertensive crisis is the extreme increasing of blood pressure which leads to organ damage.  To avoid it,
emergent measures should be done for the lowering of blood pressure.

Hypertensive crisis means hypertensive urgency and hypertensive emergency. When blood pressure achieves a high level, it leads to organ damage.

Hypertensive Urgency is the increasing of blood pressure and its reducing within a few hours without any complications and organs’ damage.

Hypertensive Emergency is a result of a hypertensive urgency. It is the very high increasing of blood pressure, which demands its immediate reduce to prevent organ damage. Help should be given at hospital.

Hypertensive Emergency leads to such organ damage as: 

* Changes in mental status: confusion or coma (encephalopathy).
* Bleeding into the brain (stroke).
* Heart damage.
* Chest pain (angina).
* Fluid in the lungs (pulmonary edema).
* Heart attack.
* Aneurysm (Bulging blood vessel).
* Eclampsia (is observed during pregnancy).

Hypertensive emergency is observed when hypertension is not treated or the use of medicines is missed.

The symptoms of Hypertensive Emergency are: 

* Headache
