Low blood pressure refers to diastolic blood pressure. Initial high diastolic blood pressure may be a transient elevation caused by physiological factors, but if it persists for a long period of time, it is suspected to be high blood pressure, which needs to be improved through general measures and medication according to the actual situation. 1. General measures: For transient high diastolic blood pressure caused by emotional excitement, exercise and other physiological factors, usually adjust the emotion in time, and the blood pressure can recover by itself after resting for a period of time. However, it is still necessary to improve bad habits, maintain emotional stability, avoid prolonged mental tension, and make appropriate exercise plans according to the actual situation to avoid overwork. 2. Pharmacological treatment: for patients with high diastolic blood pressure for a long time and suspected to be hypertensive at the beginning, not only should they take the general measures mentioned above, but they also need to follow the doctor’s instructions to apply angiotensin II receptor antagonists such as chlosartan and valsartan, or angiotensin-converting enzyme inhibitors such as captopril and benadryl. To summarize, patients with initial high diastolic blood pressure need to go to the hospital in time, cooperate with doctors for active treatment, and strengthen daily life management.
