Huazi saw a message from a fan saying that his high pressure ( systolic blood pressure ) is not high, and only the low pressure (diastolic blood pressure) is increased. What is the reason? What antihypertensive drugs should be used to control low pressure , and will the effect be better?
Huazi said that all antihypertensive drugs reduce high pressure and low pressure together, and there are no antihypertensive drugs that reduce low pressure alone. There are different types of elevation of low pressure. Using drugs such as , sartan or lor can have a better control of low pressure. How to choose medication, heart rate is an important indicator.
1. First understand what low pressure is
Everyone knows that blood pressure is divided into high pressure and low pressure. high pressure is closely related to the elasticity of the arterial . The elasticity of the large artery in the elderly is weakened. When the heart contracts, the large artery cannot fully expand and accommodate blood, resulting in an increase in the pressure of the heart to pump blood, which is manifested as an increase in high pressure. Young people have good elasticity and the resistance to heart contraction is not large, so high pressure generally does not increase.
Low pressure is the pressure on the blood vessel wall when the large artery retracts elastically during the diastolic period of the heart. The factors related to low pressure, in addition to the elasticity of the large artery, also have the resistance of the peripheral artery . The greater the elasticity of the large artery, the greater the peripheral resistance of , the higher the low pressure will be.
The good arterial elasticity is good for health, so the main factor affecting low pressure in is peripheral arterial resistance .
2. Why does peripheral artery resistance increase
1. Sympathetic nerve hyperexcitation : The reason for the increase in low pressure in some people is the excessive excitement of the sympathetic nervous system. Typical manifestations of are the speed up resting heart rate . While the low pressure increases, resting heart rate exceeds 80 times per minute.
2, renin over-secretion : There is renin- angiotensin-aldosterone system (RAAS) in the human body. When is secreted too much renin, it will cause excessive activation of RAAS, causing blood pressure to rise , but the heart rate will generally not increase. Going to the hospital for renin-related examinations can assist in diagnosis.
These two causes include smoking, excessive drinking, obesity, increased lipids in , irregular work and rest, excessive mental stress, kidney disease and other factors.
3. The choice of antihypertensive drugs depends on the heart rate
Commonly used antihypertensive drugs include dipine, pril, sartan, olol, diuretics, etc. Among them, pril and sartan have significant inhibitory effects on RAAS; lol has inhibitory effects on sympathetic nerve .
Therefore, if is overexcited by sympathetic nerves, it is suitable to use Lorrel drugs; if renin is too secreted, it is suitable to use Priligy or Sartan drug . It should be noted that one of Priligy and Sartan can be selected, but the two drugs cannot be used in combination.
When choosing medication, resting heart rate is an important reference indicator. If it is greater than 80, it is more likely to choose olol. If it is less than 80, it is more likely to choose pril or sartan. Since Priligy drugs can easily cause adverse reactions to dry cough, sartan drugs are now more commonly used.
4. Life intervention reduces blood pressure
Only people with elevated low pressure are mostly middle-aged and young people. This type of blood pressure is the early stage of hypertension . The major artery has not been damaged yet. As long as it can be controlled in time, it will generally not cause serious consequences.
The increase in low pressure is particularly close to lifestyle . Many people can effectively control the increase in low pressure by losing weight and exercising regularly. People who have too much pressure in their lives or have long-term negative emotions such as anxiety and depression may be likely to return to normal after getting rid of stress or easing their emotions.
However, if you suffer from anxiety disorder, depression , you need to get out of it with the help of a psychologist.
To sum up, if only low pressure increases, it means that the elasticity of the large artery blood vessels is normal, and it is only the initial stage of hypertension. Timely control will avoid organ damage. When choosing medication, resting heart rate is an important reference, which can help us distinguish whether there is a problem with sympathetic nervous system or renin system, and thus choose the most suitable antihypertensive drug.
