The diagnosis of hypertension is reached when the high pressure exceeds 140 mmHg, and the patient’s expression should mean that the high pressure has exceeded 140 mmHg, but the low pressure is still in the normal range. In the classification of hypertension, there is a blood pressure called simple systolic hypertension, refers to systolic blood pressure more than 140mmHg and diastolic blood pressure is less than 90mmHg. This is common in older people, mainly because of the relative sclerosis of the arteries in people of advanced age, vascular diastolic elasticity is not good, so that the diastolic blood pressure is not particularly high, or even lead to an increase in pulse pressure difference, diastolic blood pressure is reduced. When a similar situation occurs, the patient must standardize oral antihypertensive drugs for antihypertensive treatment. In the case of elderly people, over 65 years old, most of the blood pressure is only below 150 mmHg without special treatment. If the elderly can tolerate the lowering of blood pressure, try to lower it to below 140 mmHg. For those over 75 years of age, temporary observation can be done when the blood pressure does not exceed 150 mmHg.
