It is the latest to the categories of classification of blood pressure or hypertension. The concept of pre hypertension since it came to the medical scientific arena has caused many controversies. Know all about Pre hypertension
Pre-hypertension is addressed for patients who frequently have systolic blood pressure figures of 120 to 139 mmHg. And from 80 to 89 mmHg of diastolic blood pressure (PAD) or both. So the normal blood pressure classification is for people with lower figures. That is to say, this category brings together in two stages the arterial hypertension. In summary, normal pressure (120/80 to 129/84) and high normal pressure (130/85 to 139/89).
On the other hand, the denominations of the category of arterial pressures between the figures evidently or clearly normal.
That is 3 categories before reaching the established hypertension and which are:
Optimal blood pressure: SBP values less than 120 and PAD less than 80 mmHg
Normal blood pressure: SBP values from 120 to 129 and PAD from 80 to 84 mmHg and
High normal blood pressure: SBP values from 130 to 139 and PAD from 85 to 89 mmHg
There are global hypertension organizations that do not consider the category of prehypertension. And they maintain the optimal and normal categories and consider the normal high as within the North American assessment of prehypertension. This last classification is more attractive in its figures and is closer to the criteria that gave rise to its proposal. But related to the observations of the continuous increase of cardiovascular risk in the subjects. And with arterial pressures from 115 mmHg of PAS and from 70 to 75 mmHg PAD.
The category of prehypertension has been proposed from 120 and 80 and not from 115 and 75. To make its recognition as a cut-off point valid to prevent the risks that these blood pressure values entail.
Optimum blood pressure is considered normal, less than 120 mmH of PAS. And less than 80 mmHg of PAD.
Already prehypertension has led groups of researchers to assess its true meaning. Prehypertension is more frequent among men and among African Americans. But it is lower in older people as a result of a higher prevalence in these ages of hypertension. The chances of high cholesterol levels, obesity and overweight and diabetes mellitus, were higher in prehypertensive patients.
Prehypertensive patients may have a cardiovascular risk factor, than normotensive patients. Experts reaffirm the need to identify people with prehypertension well and offer them guidance. As well as relevant therapeutic measures when necessary.
