In fact, mild hypertension is mainly seen in young people, and this kind of hypertension is mainly related to the increase of diastolic pressure. If the patient is young and has mild hypertension mainly related to the increase of diastolic blood pressure, such patients are all based on the increase of high sympathetic activity and high RAS activity. At this time, the use of β receptor blockers, especially the β receptor blockers jointly blocked by α and β, has a better effect, because most of these patients have high blood pressure and a faster heart rate. However, if the heart rate is not fast and the beta blocker is difficult to take a dose, it is also a good treatment method for such people to use RAS system inhibitors, whether using ACEI or ARB. If it is slightly elevated, it can be controlled basically by a single drug, and there is generally no need for combined medication. If it is an older person who has a slight increase in blood pressure, that is, a slight increase in blood pressure, which occurs only when he is older, it would be better to use calcium antagonists first, because older people are very sensitive to calcium antagonists and are not prone to headaches. At the same time, an examination should be carried out to check whether there is secondary hypertension, such as whether there is stenosis in a renal artery, whether there is adenoma in the adrenal gland, etc.
