3.1 - Acute crisis of blood pressure

The principal risk is the appearance of an acute crisis of blood pressure, corresponding to the sudden appearance of a very high arterial blood pressure: the maximum blood pressure (systolic) is often higher than 250 millimetres of mercury (25) whereas the minimal blood pressure (diastolic) is higher than 130 millimetres of mercury (13).

The symptoms will be primarily neurological and associated with convulsions, violent headaches and vomiting. In an extreme state, a loss of consciousness or a coma can occur, just as a massive haemorrhage in the brain, which is then responsible for a hemorrhagic cerebral vascular attack.

But also an acute crisis of blood pressure can involve an oedema in the lung, which hinders the breathing: the patient feels an oppression in the chest, cannot breathe normally and has the feeling of choking.
