is defined as a chronically increased blood pressure.
The majority of people with hypertension do not know they are affected because hypertension evolves insidiously over the years.
Hypertension is the most common cardiovascular disease
and is the most important of risk factor.
Blood pressure is the pressure exerted by the blood pumped by the heart against the walls of arteries
Blood pressure is the force that helps the blood
to circulate through all the organs. In cases of hypertension, when the pressure is too high, the heart has to work harder then. High blood pressure
means that the blood pressure is abnormally high.
Blood pressure is divided into two values??:
- systolic blood pressure, the maximum,
- diastolic blood pressure, the minimum.
Blood pressure is therefore expressed by two digits. The values ??of blood pressure, more commonly known as high blood pressure, are shown in inches of mercury (Hg).
Systolic blood pressure
The highest systolic blood pressure, is the value in blood pressure during the cardiac systole during ventricular contraction.
This is the pressure in the vessels at the time when the heart contracts.
Systolic pressure is the highest figure: for example, a blood pressure of 13/8, it is the number 13.
Diastolic blood pressure
Diastolic blood pressure is the value of blood pressure during cardiac diastole occurring during ventricular relaxation.
This pressure occurs in the arteries between two heart contractions during this phase of relaxation and filling of the heart.
Diastolic pressure is the lowest figure. For example, a blood pressure of 13/8, it is the number 8.
Normal blood pressure
Blood pressure is normal when it is less than 14/9 or 140/90 mmHg.
Low blood pressure
A too low blood pressure corresponding to a decrease in blood pressure below 90 mm Hg for the maxima is called hypotension.
High blood pressure
Systolic blood pressure should not be greater than the number 15.
Diastolic blood pressure must not exceed the number 9.
Hypertension is defined as a value greater than 14/9.
