Definition of hypertension, identification of borderline hypertension and pseudohypertension

> 4. **High Blood Pressure**

As people's knowledge of medical and health care continues to improve, they are paying more and more attention to their health.

Many people are also very concerned about whether their blood pressure is normal and whether they have high blood pressure.

Hypertension is defined as a systolic blood pressure ≥160 mmHg and a diastolic blood pressure ≥95 mmHg in adults.

The values ​​fall between these two ranges, that is, systolic blood pressure is 141–159 mmHg and diastolic blood pressure is 91–94 mmHg.

This is borderline hypertension. Diagnosing hypertension requires multiple blood pressure measurements, at least in consecutive periods.

A diagnosis of hypertension requires an average diastolic blood pressure reading of 90 mmHg or higher from two consecutive measurements. Only one measurement...

Those with elevated blood pressure cannot be diagnosed yet, but need to be followed up and observed.

What factors are related to blood pressure formation? Firstly, it is affected by the average filling of the circulatory system, which refers to...

When the heart is beating, the blood throughout the body gradually stops flowing, and the pressure at various points within the blood vessels decreases.

The same value is reached, which is the average filling pressure of the circulatory system, which is about 6 mmHg for a normal person.

In addition, influenced by the heart's pumping action, the flow of blood from the heart into the arteries is closely related to peripheral vascular resistance.

The higher the peripheral vascular resistance, the higher the arterial blood pressure.

The WHO recommends the following blood pressure standards:

>

Systolic blood pressure ≤140mmHg

>

Diastolic blood pressure ≤ 90 mmHg

> **5.** **Borderline hypertension**

Borderline hypertension, also known as end-stage hypertension, is characterized by a systolic blood pressure of 140–160 mmHg and a diastolic blood pressure of 90–95 mmHg.

This disease is characterized by slightly elevated blood pressure, which can affect vital organs such as the heart, brain, and kidneys.

There is no organic damage, but it is prone to developing into hypertension.

Clinical observations show that approximately 71.5% of people with borderline hypertension are prone to developing hypertension.

Only 11.1% of normal individuals have this condition. The incidence of complications such as cerebral hemorrhage, cerebral thrombosis, coronary heart disease, and mortality is comparable to that of hypertension.

The patients' conditions are similar, but significantly higher than normal. Because it lacks early organic damage and specificity...

Because the symptoms and signs are not obvious, it is easily overlooked. Prevention of this type of hypertension is the same as for regular hypertension, but...

The key is to control sodium intake, ideally to less than 5 grams per day, while increasing potassium intake, such as by eating more...

Fruits and vegetables, etc. In addition, regular physical activity is important, and calcium channel blockers may be taken long-term if necessary.

6. **Pseudohypertension**

Pseudohypertension refers to a false increase in blood pressure caused by arterial calcification. If blood pressure is only slightly elevated...

High blood pressure, no end-organ damage was found, and/or the patient rapidly deteriorated after taking antihypertensive medication.

Symptoms of decreased blood volume or low blood pressure should raise suspicion of pseudohypertension. A definitive diagnosis requires further investigation.

Oskin method test: Inflate the sleeve until the mercury column exceeds the level at which the sound disappears, then touch...

If the brachial artery is easily palpable at this point, it confirms pseudohypertension. Before considering treatment,

It is important to maintain the blood pressure of these patients at a slightly higher level.
