High lower blood pressure, which means that the patient is hypertensive with a predominantly diastolic blood pressure. The causes of high diastolic blood pressure are divided into two main areas: 1) increased peripheral vascular resistance; 2) faster heart rate; the greater the peripheral vascular resistance, the faster the heart rate, the higher the diastolic blood pressure of the patient. If you want to reduce the diastolic blood pressure, the preferred antihypertensive drugs in the clinic are the pulmonary and sartan antihypertensive drugs, which can better reduce the diastolic blood pressure, and the representative drugs are perindopril, enalapril, valsartan, and crosartan. In addition to these two causes, there are many people who may have high diastolic blood pressure for unknown reasons, but no matter what the cause of the elevated blood pressure, as long as the blood pressure is higher than the normal range, actively identify the cause and give the appropriate treatment, in order to help improve the patient’s prognosis and reduce the mortality rate.
