2.9 - The age

Scientific studies show that the blood pressure increases with age.

Of course, the age of a patient cannot be altered but the doctor must consider the age when evaluating the overall cardiovascular risk of his patient.

Thus, a 65 year-old patient who presents an arterial blood pressure of 170/95 millimetres of mercury has more risk than a 45 year-old patient.

It is thus very significant for the doctor and the hypertensive patient, to be able to evaluate the total cardiovascular risk. Equations of the risk have been established as shown in the table below.
