In fact, the harm of hypertension, on the one hand, is related to the level of hypertension, on the other hand, it is related to whether hypertension is discovered sooner or later and whether it is well controlled.
First, the traditional classification of hypertension
Hypertension is not light, moderate or severe, but divided into hypertension 1, hypertension 2 and hypertension 3. It can be approximately regarded as the corresponding mild to moderate severity.
1, classification of hypertension in China
120- 139/80-89 belongs to normal hypertension.
140- 159/90-99, belonging to 1 grade hypertension.
160-179/100-109 belongs to grade 2 hypertension.
It is greater than 180/ 1 10, which belongs to grade 3 hypertension.
2. American classification of hypertension
Blood pressure > 120- 129/80 mmhg means that blood pressure rises.
1 30-139/80-89 mmhg is1grade hypertension.
≥ 140/90mmHg is grade 2 hypertension.
Grade 3 hypertension ≥ 160/ 100mmHg.
3. The result of blood pressure measurement is different every time. How to score?
The above-mentioned hypertension classification refers to the measurement results of hospital outpatient service without medication; As for the judgment of hypertension, only when the blood pressure is higher than 140/90mmHg on different days do you need to consider hypertension, and you need to measure it twice in a row, with an interval of 2-5 minutes, and then measure it again, and the average value is your blood pressure.
If the blood pressure difference between two consecutive times is 5mmHg, you need to take the third measurement, take the average of the three times, which is your own blood pressure, and then judge according to the above-mentioned blood pressure standards in China.
4. What if the left arm is different from the right arm?
Almost each of us has a different left arm and right arm. Many people don't know whether to measure left or right. It's actually quite simple. Both sides are measured, whichever side is measured in the first year of high school shall prevail.
5. If it is not measured by the hospital, is the standard the same?
The diagnostic standard of hypertension measured by family blood pressure is ≥ 135/85mmHg, which is equivalent to 140 /90mmHg of hospital blood pressure. In other words, measuring blood pressure at home, ≥ 135/85mmHg belongs to hypertension!
Of course, more accurate is ambulatory blood pressure monitoring. The diagnostic criteria of hypertension after ambulatory blood pressure monitoring are: 24-hour average high/low pressure ≥130/80 mmhg; ≥135/85 mmhg during the day; ≥ 120/70mmHg at night.
6, high pressure and low pressure is not a level?
Hypertension can be divided into high pressure and low pressure, but when measured, high pressure belongs to grade 2 and low pressure belongs to grade 3. How to judge the level? According to the higher level, that is, when the second level and the third level appear at the same time, it is calculated according to the third level; When 1 level and level 2 appear at the same time, it is calculated as level 2.
Second, the latest classification of hypertension
The traditional classification of hypertension is divided into three levels. At present, the latest hypertension guidelines combine the second and third levels of hypertension, that is, the original second and third levels of hypertension are all second-level hypertension, and there is no third-level hypertension.
New guidelines for blood pressure grading:
140- 159/90-99 is 1 grade hypertension.
≥ 160/ 100 is grade 2 hypertension.
Third, the original grade 3 hypertension has now become grade 2 hypertension. What's the point?
Some people say that they have taken antihypertensive drugs and now their blood pressure is normal. How to classify them? As we said above, the classification of hypertension is based on not taking medicine at first.
So according to the new guidelines, is it a good thing that the former grade 3 hypertension has now become grade 2?
This is not a good thing or a bad thing, because your original blood pressure will not change, that is history. The reason why the second and third levels are merged into the second level and the third level is cancelled is that when the blood pressure exceeds 160/ 100mmHg, it is dangerous, so it is unnecessary to continue to divide the standard of180/10, so it is simplified to two levels and three levels.
Fourth, how to change the classification of hypertension, the only constant is prevention and treatment.
No matter how the grading of hypertension changes, the true meaning of preventing hypertension, living a healthy life, monitoring blood pressure and controlling hypertension remains unchanged. It is not terrible to find hypertension of 1 or 2. The terrible thing is that it has not been discovered, or it has not been actively controlled after discovery. This will cause serious damage to the heart, brain and kidney.
In short, the latest hypertension classification has changed from the original level 3 to the current level 2. Although it sounds like a downgrade, the harm of hypertension will not change, and even remind everyone to pay more attention to the prevention and treatment of hypertension!
