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.
