The normal range of systolic blood pressure for seventy years old is 90~139mmHg, and the normal range of diastolic blood pressure is 60~89mmHg. Elderly people have serious arteriosclerosis compared to adults, and the fluctuation of blood pressure is big, which is easy to cause ischemia and hypoxia of heart, brain, kidneys, and other important organs, so it is not recommended that the control of blood pressure in elderly people is too low.
The normal range of systolic blood pressure for the elderly is 90~139mmHg, and the normal range of diastolic blood pressure is 60~89mmHg. Hypertension is considered to be present when at least three non-simultaneous blood pressure values reach or exceed 140mmHg systolic and/or 90mmHg diastolic. Elderly hypertensive patients should take antihypertensive drugs, such as nifedipine, valsartan, hydrochlorothiazide, etc., on time under the guidance of a doctor.
Elderly patients with hypertension should not only take medication as prescribed by the doctor, but also have a low-salt, low-fat and low-cholesterol diet to maintain stable blood pressure, and undergo regular check-ups to prevent cardiovascular and cerebrovascular diseases.
