Why such a value?
Indeed, why can't we tolerate a higher value?
In fact, many doctors
worked extensively on this subject and found that above the value
of 14/9, the risk for the cardiovascular system is significant.
These studies required several thousands patients, whose age
varied between 18 and 85 years. On average, the duration of these
studies varied from 5 to 20 years.
We know that the higher
the blood pressure value, the more significant the cardiovascular
risk becomes, testified to this study carried out by an American
insurance company in the Sixties:
