Students, today we are learning about hypertension.

Hypertension (also known as high blood pressure) is a phenomenon in which the pressure on the blood vessel wall caused by blood flow is continuously higher than normal. According to the "Chinese Hypertension Clinical Practice Guidelines", the diagnostic criteria for adult hypertension are systolic blood pressure ≥130mmHg and/or diastolic blood pressure ≥80mmHg. The causes of hypertension are mostly genetic factors and unhealthy lifestyles, such as high-salt diet, excessive drinking, long-term mental stress and lack of physical activity. Hypertension is prone to occur in 5 groups of people: people with a family history; people who are easily excited; people with high salt intake; people who are addicted to alcohol; people with high work or life pressure.

Typical symptoms of hypertension include headache, fatigue or restlessness, arrhythmia, palpitations and tinnitus, etc. However, many patients with hypertension may have other complications without any symptoms, such as stroke, blurred vision, loss of consciousness, amnesia, etc., so hypertension is called the "silent killer."

For patients with hypertension, improving lifestyle and drug therapy are the most commonly used treatments. The basic principles of drug therapy include giving priority to long-acting antihypertensive drugs, controlling 24-hour blood pressure, and adjusting drugs and dosages as needed. If the blood pressure of patients with hypertension is not controlled for a long time, it may lead to more serious complications and even fatal consequences such as stroke and cerebral infarction.

The latest survey shows that the prevalence of hypertension among Chinese adults is 27.9%, which means that about one in three adults has hypertension. The prevalence of hypertension in rural areas has exceeded that in cities, and the prevalence of hypertension is even higher among Tibetans, Manchus and Mongolians.

The cause of hypertension is a difficult problem that scientists around the world are constantly exploring. The cause of most hypertension patients is still unclear. In the past, this type of hypertension was called "primary hypertension", but this name has become a thing of the past, and it is now collectively referred to as hypertension.

Among patients who present with hypertension, 5% have high blood pressure due to certain definite diseases or causes. This is called secondary hypertension. This type of hypertension can be cured or improved by treating the disease that causes the high blood pressure.

Many patients with hypertension have developed other asymptomatic diseases without feeling any discomfort. This is commonly known as target organ damage, so hypertension is called the "silent killer."

In fact, hypertension sometimes has some less specific symptoms, such as headache, paroxysmal dizziness, chest tightness, numbness of the limbs, etc. At this time, both the patient and the attending doctor should be alert to whether it is a sign of early hypertension.

Most patients with hypertension do not have typical symptoms, and are easily overlooked and not promptly treated. This suggests that high-risk groups should understand the general symptoms of hypertension and seek medical attention as soon as possible if they feel any discomfort. For the general population, if there is any indication of elevated blood pressure during any medical consultation or physical examination, they should pay attention and have regular follow-up examinations to allow professional doctors to make judgments on the elevated blood pressure.

The fundamental goal of hypertension treatment is to reduce the overall risk of cardiovascular, cerebrovascular, renal and vascular complications and death. The benefits of antihypertensive treatment mainly come from the reduction of blood pressure itself. For ordinary hypertensive patients, it is recommended to decide whether to give antihypertensive drugs and drug treatment plans based on the overall risk level of hypertensive patients on the basis of improving their lifestyle.

For patients with gestational hypertension, the main purpose of treatment is to ensure the safety of mother and baby and the smooth progress of pregnancy and delivery, reduce complications and lower mortality. For patients with mild hypertension, non-drug treatment should be emphasized, and blood pressure should be actively monitored, and urine routine and other related examinations should be regularly reviewed.
