High pressure (systolic blood pressure) is not too high and low (diastolic blood pressure) is high, mostly in young and middle-aged hypertension and workplace hypertension.
1. How is the systolic and diastolic pressure formed?
The circulatory system of the human body includes the heart and blood vessels, which are connected to each other and form a closed “pipe system”. The heart is like a pump, beating day and night, rhythmically, making blood circulate in the circulatory system.
When the heart shrinks, a lot of blood is instantly into the blood vessels, the pressure in the large artery is sudden, and the blood pressure is called the systolic pressure, commonly known as the pressure. When the heart diastole, the heart no longer releases blood into the blood vessel, the dilated blood vessel retracts because of elasticity and continues to move forward, so the blood vessel is still in the blood vessel. To maintain a certain pressure, the pressure is diastolic blood pressure, commonly known as low pressure.
The factors that determine blood pressure are the elasticity of the arteries and the contractility of the heart.
The elasticity of the arteries and the contractility of the heart are normal, and the blood pressure is normal. If the arterial elasticity decreases, the buffer function of the tube wall decreases obviously, the enlarged artery dilatation amplitude decreases and the systolic pressure is high, while the systolic blood pressure decreases and the diastolic pressure will be very low. This is called isolated systolic hypertension, which is mainly seen in elderly people with decreased elasticity of blood vessels.
While the rate of heart rate is faster, the diastolic phase of the heart is obviously shortened, the large artery is always in high pressure, the diastolic pressure will increase, or the resistance of the peripheral blood vessels increases, which makes the blood flow to the whole body when the heart contractions, to the diastolic artery still more blood, and the diastolic pressure will also increase, this case is often seen in the middle of the situation. Puber。
In a word, anxiety, stress, obesity and less movement, lack of sleep, smoking and drinking, and so on, can cause increased heart rate and increased peripheral vascular resistance, and eventually lead to an increase of diastolic pressure.
Two, how to effectively reduce the diastolic pressure?
First, change the habits of life, weight loss exercise, regular sleep, adjust the mentality, smoking cessation limit alcohol and so on, early mild diastolic pressure can even be controlled without drugs to control the standard.
Antihypertensive drugs with high diastolic pressure:
1, sartan or prili hypotensive drugs: the two all play the antihypertensive effect against angiotensin II, and also reduce the sympathetic nerve excitability, and reduce the diastolic pressure by slowing down the heart rate and dilating blood vessels.
Sartan and Puli can only choose one and the two can not be used together.
2, beta blockers: mainly using second generation of beta blockers such as Mei TORO M (Betaloc), atenolol (amyl amine), bisolol (Kang Xin), and third kinds of beta blockers such as A Luo lol, carvedilol, and La billol.
Beta blocker reduces diastolic pressure by slowing down heart rate and reducing cardiac contractility, and is more advantageous to the increase of diastolic pressure caused by mental factors such as tension and anxiety.
