The basic definition of hypertension and the significance of controlling blood pressure

Broadly speaking, adults with blood pressure ≥140mmHg and/or 90mmHg are hypertension, and this data has nothing to do with age.

In my country, there is a survey on hypertension. The data shows that the prevalence rate of adult hypertension in my country is as high as 25.2%, and the number is as high as 270 million. Hypertension is the chronic disease with the highest prevalence rate in China.

What are the serious harms of high blood pressure?

It is known that hypertension is the most important risk factor leading to myocardial infarction, cerebral infarction, and renal failure.

According to statistics, 2 million people die from diseases related to high blood pressure each year across the country.

Moreover, a survey found that more than 60% of patients with coronary heart disease, more than 80% of patients with cerebral infarction, and 90% of patients with cerebral hemorrhage have a history of hypertension.

It can be said that high blood pressure is the most important "killer" of human health.

Therefore, a correct understanding of hypertension and strict control of blood pressure are of great significance.

The occurrence of high blood pressure is related to genetics and unhealthy lifestyles.

To control high blood pressure, in addition to drug treatment, lifestyle should also be improved, but drug treatment is undoubtedly the main measure.

So, during the perioperative period, when should the antihypertensive treatment be initiated and what goal is appropriate for the blood pressure to drop?


The concept of early enhanced blood pressure reduction was previously advocated. At present, it is recommended that the blood pressure target value of most patients should be reduced to below 130/80mmHg if they can tolerate it.
