Blood pressure measured in the office at age 43 should be 60~139mmHg systolic, 60~89mmHg diastolic, and 20~40mmHg pulse pressure. 1. Normal blood pressure range has nothing to do with age, although the blood pressure may rise slightly with age and the elasticity of blood vessels deteriorates, it should still be within the normal blood pressure range. the normal blood pressure range of 43-year-olds is the same as the reference value of normal adults. 2. Within the normal blood pressure range, if the systolic blood pressure is 90~119mmHg and the diastolic blood pressure is 60~79mmHg, it is normal blood pressure; if the systolic blood pressure is 120~139mmHg and/or the diastolic blood pressure is 80~89mmHg, it is normal high-value blood pressure, and the latter has an increased possibility of developing into high blood pressure. Pulse pressure is the difference between systolic pressure and diastolic pressure, which should be 20-40mmHg. 3. Measurement of blood pressure in the office on three occasions not on the same day with systolic blood pressure ≥140mmHg and/or systolic blood pressure ≥90mmHg is considered hypertensive, while systolic blood pressure <90mmHg and diastolic blood pressure <60mmHg is considered hypotensive. It is recommended that the middle-aged population should also have their blood pressure checked regularly, and the presence of high or lower than normal values should result in a review of blood pressure after eliminating the influencing factors, and prompt medical attention.
