How to determine whether suffering from high blood pressure? How to measure blood pressure more accurately?

How can ability determine whether to suffer from hypertension? Hypertension refers to the blood flow of the human body in the blood vessels? It can lead to coronary heart disease, stroke and other serious diseases. The risk factors of hypertension include obesity and overweight, mental stress, smoking and drinking, high-salt diet and so on. In the absence of antihypertensive drugs, hypertension can be diagnosed when systolic blood pressure (high pressure) ≥ 140mmHg (mm Hg) or diastolic blood pressure (low pressure) ≥ 90mmHg (mm Hg) is measured three times in the same day, and the average blood pressure ≥ 135/85mmHg (mm Hg) can be diagnosed as hypertension, that is to say, hypertension is a persistent state. There is a transient increase in blood pressure, first of all, take a rest for 10 minutes before measuring blood pressure, do not do strenuous exercise within half an hour before measuring blood pressure, blood pressure should be measured in the morning and evening, and blood pressure should be measured within 1 hour after getting up in the morning.

Today (17th) is "World Hypertension Day". Hypertension is one of the most common chronic diseases. according to the statistics of the National Cardiovascular Disease Center, there are nearly 300 million patients with hypertension in China. So, what is hypertension? How can you determine whether you have high blood pressure?

How can ability determine whether to suffer from hypertension?

Hypertension refers to the phenomenon that the pressure on the blood vessel wall is higher than normal when the blood of the human body flows in the blood vessels. Hypertension is often called a silent killer, which can lead to coronary heart disease, stroke and other serious diseases. The risk factors of hypertension include obesity and overweight, mental stress, smoking and drinking, high-salt diet and so on.

Medical staff suggest that hypertension can be diagnosed when systolic blood pressure (high pressure) ≥ 140mmHg (mm Hg) or diastolic blood pressure (low pressure) ≥ 90mmHg (mm Hg) is measured three times in the same day without antihypertensive drugs. The average blood pressure ≥ 135/85mmHg (mm Hg) can be diagnosed as hypertension. In other words, hypertension is a persistent state, it needs to be reminded that if the occasional measurement of blood pressure, there is a transient increase in blood pressure, it can not be defined as hypertension.

How to measure blood pressure more accurately?

How to measure blood pressure accurately? When is it more accurate to measure blood pressure? According to medical staff, the first thing is to take a 10-minute break before measuring blood pressure to ensure a stable emotional state. In addition, do not do strenuous exercise for half an hour before measuring blood pressure.

Wang Zengwu, director of the Community Prevention and Control Department of the National Cardiovascular Disease Center: when measuring, try to keep your feet flat, then sit up straight, and then keep the level of the sphygmomanometer in the same position as the heart. In addition, when the cuff is tied, it should also be able to wrap 80% of our upper arm, and then the lower edge of the cuff should be about two fingers away from our elbow lines, which is generally required to be 2.5 cm.

Medical staff suggest that blood pressure should be measured in the morning and evening, usually within 1 hour after getting up, before taking antihypertensive drugs, before breakfast, and before strenuous activities. Blood pressure at night was measured after dinner and before going to bed. It should be noted that the electronic sphygmomanometer should be calibrated regularly at least once a year during use.

Is there no need for treatment without symptoms of hypertension?

The symptoms of hypertension vary from person to person, some patients with early hypertension do not have any symptoms, or the symptoms are not obvious. Therefore, some patients think that if there are no symptoms, there is no need for treatment, is that so?

Zhang Huimin, deputy director of the difficult Hypertension consultation Center of the National Cardiovascular Research Center: in fact, this is a big misunderstanding. There are many patients with high blood pressure. He may be a little dizzy and have a headache occasionally. He doesn't care about it. Over time, he has tolerated this increase in blood pressure, so he has no symptoms at all. For example, we have seen that the blood pressure has even reached 180 / 120 mm Hg in clinical practice. The patient still has no symptoms, but when you re-examine, you will find that his heart is damaged, his kidney is damaged, and even this kind of stroke occurs, so no symptoms, it does not mean that there is no harm, if there is high blood pressure, you must see a doctor in time and take medicine in time.

Worry about the side effects of drugs, want to lower blood pressure and fear long-term use of antihypertensive drugs to hurt the body, this is a problem that many patients with high blood pressure will encounter in the course of treatment. So, what should we do now?

Zhang Huimin, deputy director of the difficult Hypertension consultation Center of the National Cardiovascular Research Center: in fact, if you have a definite diagnosis of hypertension, you must take the medicine. Many people are worried about the adverse reactions of the drug. In fact, first, the dose of the drug is very small. There will be no obvious harm to the body. Second, even if some drugs have some adverse reactions, these adverse reactions are not persistent and can disappear after drug withdrawal. So we can switch to other drugs that have no adverse reactions to individuals. After you take the medicine, it will protect your heart, brain and kidney blood vessels.
