Core tip: according to Professor Liu Lisheng, there is a circadian rhythm in blood pressure, which is intrinsically related to the body's biological clock. In the vast majority of hypertensive people with normal blood pressure and no complications, the blood pressure decreased during sleep at night, which was the lowest at about two or three o'clock in the morning. Blood pressure rises rapidly before waking up in the morning and reaches or approaches the peak in the first few hours after waking up (about 6-9 AM).
The current blood pressure control rate in China is only 6.1%, which means that nearly 94% of patients with hypertension can not safely spend a day when their blood pressure is continuously and stably controlled, and the compliance rate of 24-hour blood pressure control is directly related to the incidence of cardiovascular and cerebrovascular diseases.
In the morning of the day, Professor Liu Lisheng stressed that the "morning blood pressure" should be paid attention to make the blood pressure "more stable", because the incidence of stroke, angina pectoris, sudden death, and myocardial infarction is the highest at this time.
Blood pressure peaked in the morning
According to Professor Liu Lisheng, there is a circadian rhythm in blood pressure, which is intrinsically related to the body's biological clock. In the vast majority of hypertensive people with normal blood pressure and no complications, the blood pressure decreased during sleep at night, which was the lowest at about two or three o'clock in the morning. Blood pressure rises rapidly before waking up in the morning and reaches or approaches the peak in the first few hours after waking up (about 6-9 AM).
Due to vascular sclerosis in the elderly, the blood pressure changes more obviously within 24 hours. The blood pressure rises rapidly in the morning, even up to 50 mmHg, which is called the "morning blood pressure peak" in medicine.
Morning blood pressure surge can increase the pressure of the cardiovascular system and increase the risk of cardiovascular events. Therefore, the hours after waking up in the morning are also the most dangerous time of the day for hypertensive patients.
You have to control your blood pressure 24 hours a day
However, it is not easy for a patient with hypertension to have stable blood pressure for 24 hours. The fluctuation of blood pressure is affected by many environmental and individual factors. Besides, some patients stop taking drugs without permission when they think their blood pressure is normal, and some patients often miss taking drugs inadvertently. All of these have brought obstacles to obtain 24-hour blood pressure control. Professor Liu Lisheng pointed out that in the treatment, the selection of drugs that can really reduce blood pressure for 24 hours can improve the blood pressure control rate, help patients obtain 24-hour healthy blood pressure, safely relieve the "morning blood pressure peak", and reduce the incidence of cardiovascular and cerebrovascular events in the morning.
According to the European Union's guidelines for hypertension prevention and treatment published in 2007, there should be one-hour drug use priority in China when compiling the "hypertension prevention and treatment guidelines". However, there are many antihypertensive drugs recommended once a day in clinical practice, but in fact, some drugs are difficult to control blood pressure once a day for 24 hours. This requires patients with hypertension in the treatment should strictly follow the doctor's advice, choose in the true sense of continuous 24 hours antihypertensive drugs.
Blood pressure can't be controlled by drugs alone
Professor Liu Lisheng finally pointed out: at present, the task of prevention and treatment of hypertension in China is still very serious. Not only patients with a high risk of hypertension need to receive treatment, but all patients with hypertension need to accept the recommended treatment plan, including lifestyle intervention, such as smoking cessation and weight loss (and maintaining body weight), reducing alcohol intake, physical exercise, reducing salt intake, increasing the intake of fruits and vegetables, reducing the intake of saturated fatty acids and total fat, etc., to minimize the overall risk of long-term cardiovascular disease. The theme of this year's "National Hypertension Day" is "healthy diet, healthy blood pressure". We should encourage residents to form healthy diet and good living habits, form awareness of self prevention and self-management of blood pressure, and create a social atmosphere for everyone to participate in maintaining healthy blood pressure through the joint participation of the government, medical and health institutions, media, enterprises, and academic groups.
