What is high blood pressure?
High blood pressure is a common cardiovascular disorder. It concerns more than 10 million people in France. Usually, blood pressure - blood pressure in the arteries - is about 12/8 cmHg (centimeters of mercury). The first number corresponds to the blood pressure measured during the relaxation phase of the heart (diastolic pressure). The second digit, to the measurement taken during the contraction phase of the heart (systolic pressure).
Blood pressure varies during the day. In a situation of stress or intense emotion, it rises naturally. When the blood pressure remains high, beyond 14/9 cmHg, we talk about high blood pressure.
