The normative term for high blood pressure is high diastolic blood pressure, which may be transiently elevated and pathologically elevated, and needs to be alleviated by general treatment, medication, and surgical treatment according to different situations. 1. Transient elevation: under normal circumstances, the fluctuation of blood pressure is physiological, under exercise, emotional excitement, mental stress, fatigue, etc., the blood pressure will be physiologically elevated, resulting in high diastolic blood pressure, etc., and after resting and improving the above factors, the blood pressure can be lowered to the normal range. 2. Pathological elevation: some patients have elevated diastolic blood pressure caused by pathological factors, such as increased peripheral vascular resistance, etc. If it is primary hypertension, it needs to be treated with medicines under the guidance of doctors, and commonly used medicines are nifedipine, valsartan, candesartan, etc. If it is secondary hypertension, such as valsartan, candesartan, etc., it is necessary to apply medicines under the guidance of doctors to treat it. In case of secondary hypertension, such as renal artery stenosis, surgical treatment is required. If the diastolic blood pressure is elevated at different times on non-three days of continuous testing, it is recommended to go to the hospital in time, to clarify the cause of the disease, and then carry out targeted treatment.
