Hypertension Knowledge Science

1. Q: What is blood pressure?

Answer: The pressure on the blood vessel wall when blood flows in the blood vessel is the blood pressure, which is similar to the pressure of tap water on the water pipe. When blood pressure reaches a certain value, blood can flow, and blood flow is powered by the heart.

Someone's blood pressure is 120/80, 120 is "high pressure", 80 is "low pressure". The way the heart works is "one contraction and one contraction", similar to the "one-on-one grip" of a fist; the blood pressure produced when the heart contracts is high pressure, also known as systolic pressure; the blood pressure produced during diastole is low pressure, also called diastolic pressure.

2. Q: What is hypertension?

Answer: If a normal adult does not take antihypertensive drugs, if the three blood pressures not measured on the same day all reach high pressure ≥140 and/or low pressure ≥90, it is hypertension. Regardless of high pressure (≥140) or low pressure (≥90), it is high blood pressure.

3. Q: When is the most accurate blood pressure measurement?

A: The blood pressure during the day is constantly changing, high during the day and low at night. The blood pressure is lowest at 2 to 3 in the morning, the highest blood pressure at 6 to 10 in the morning and 4 to 8 in the afternoon, which is "two peaks and one valley." Blood pressure can be measured during two peak periods. If the blood pressure is not high during these two peak periods, the blood pressure is well controlled.

4. Q: What are the common symptoms of hypertension?

A: There are headaches, dizziness, palpitation, chest tightness, tinnitus, insomnia, memory loss, hardened back neck, dislike to interact with people, decreased sexual function, easy to be excited, etc.

5. Q: Why do some patients with hypertension have no symptoms?

A: Most patients with high blood pressure have no symptoms, and only a few patients will experience these symptoms. This is because blood pressure rises slowly, patients often do not feel it, and some mild symptoms are easily overlooked by patients.

6. Q: Is high blood pressure not dangerous without symptoms?

Answer: Some diseases are symptomatic and not dangerous, such as toothache, but high blood pressure is not symptomatic and dangerous, so they are called "invisible killers." High blood pressure is just like an earthquake. Normally, once it breaks out, a good person can be turned into a waste or dead person within a few minutes. Asymptomatic hypertension can not remind people to actively treat, and the risk is greater. Therefore, once hypertension is diagnosed, it should be treated immediately. The sooner it is treated, the less damage the vital organs such as the heart, brain, kidneys, and blood vessels.

7. Q: What are the consequences of high blood pressure?

Answer: The main consequences of hypertension can be summarized as: "big heart, small kidney, stroke".

Big heart: High blood pressure overloads the heart all year round. First, the left ventricle is hypertrophic, then the heart gradually becomes larger, and finally develops heart failure.

Small kidney: High blood pressure hardens the blood vessels of the kidneys, the blood supply is not up, the kidneys gradually shrink and become smaller, the function declines, and slowly develops into uremia.

Stroke: Hypertension causes cerebral hemorrhage and cerebral infarction, which are collectively referred to as stroke.

When the heart, brain and kidney are damaged by the above, the corresponding consequences are: heart failure, kidney failure, cerebral infarction and cerebral hemorrhage. In addition, high blood pressure can also cause serious consequences such as myocardial infarction, blindness, and amputation.

8. Q: How much is better to control blood pressure?

A: Each person's physical condition and accompanying diseases are different, and the requirements for blood pressure control are also different, as follows:

Normal blood pressure should be: 120/80;

Ordinary hypertension patients: below 140/90;

Diabetes and kidney disease patients: below 130/80;

Hypertension patients over 60 years old: under 150/90.

9. Q: Should antihypertensive drugs be changed frequently?

Answer: Do you need to change the dressing mainly depends on the current effect; whether the blood pressure drops smoothly; whether the side effects of the drugs used are relatively small. Antihypertensive drugs are not the same as cold medicines. They will not be eaten for three or five days. Antihypertensive drugs will take decades. If the plan is suitable, the effect is satisfactory, and the side effects are also small, it is not necessary to change the medicine frequently.

10. Q: Is there any dependence on antihypertensive drugs?

Answer: Some people are worried about the dependence of antihypertensive drugs. Once they eat it, they can't do without it. In fact, antihypertensive drugs have no dependence. Long-term use is because hypertension requires long-term medication control and is a disease-dependent drug. Professor Hu Dayi said: Hypertensive patients must insist on taking medicine, "Never forget a meal, do not forget a medicine, live a day to eat a day." Do not stop the medicine if the blood pressure is low, and eat again when the blood pressure is high, which makes it very bad for the blood pressure to fluctuate repeatedly.
