High blood pressure, i.e., high diastolic blood pressure, is mainly due to increased peripheral vascular resistance and increased heart rate. The main causes are increased peripheral vascular resistance, increased heart rate, etc. Treatment is mainly life improvement and drug therapy. 1. Causes:When atherosclerosis occurs, the peripheral vascular resistance increases, and more blood remains in the large blood vessels at the end of the diastolic period of the heart, or when the heart rate is too fast and the time for blood to flow to the periphery is shortened, the amount of blood remaining in the aorta at the end of the diastolic period is increased, which may lead to an increase in diastolic blood pressure. 2. Treatment: Improvement through life, such as diet, pay attention to avoid high-calorie, high-fat food, reduce plasma cholesterol, to prevent atherosclerosis, has a certain effect on reducing diastolic blood pressure, or through physical exercise, such as jogging, swimming and so on, is conducive to vasodilatation. For drug treatment, you can follow the doctor’s instructions and take β-blockers such as betalactam, which can play a role in slowing down the heart rate, thus making the diastolic blood pressure drop, or take Puli or sartan drugs, such as captopril, valsartan, etc., which can diastole the blood vessels and reduce the peripheral resistance. If high diastolic blood pressure occurs, you should consult a doctor in time to find out the cause, and then the doctor will choose the appropriate drug treatment, so as to avoid subsequent aggravation of symptoms to produce disease.
