A 45 year old with a blood pressure of 145/95 mmHg above normal is hypertensive if the blood pressure is still high on retesting, but not hypertensive if the blood pressure is normal on retesting.
The diagnosis of hypertension requires that all three retests on a different day have a systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥90 mmHg. Normal blood pressure is 90 mmHg ≤ systolic blood pressure <140 mmHg and 60 mmHg ≤ diastolic blood pressure <90 mmHg.
The diagnostic criteria for hypertension as well as the normal blood pressure range are independent of age, and the criteria for hypertension and normal blood pressure range at 45 years of age are consistent with the above. Therefore, at the age of 45, the systolic blood pressure of 145 mmHg and diastolic blood pressure of 95 mmHg are higher than the normal blood pressure range, but whether the diagnosis of hypertension can be made needs to be combined with the results of retesting.
If the retested blood pressure is still higher than normal, hypertension can be diagnosed; if the retested blood pressure is normal, the abnormality may be caused by physiological fluctuation of blood pressure, and the overall blood pressure is still normal.
It is recommended that patients should have their blood pressure retested. If the retest is abnormal, they should consult a doctor and follow the doctor's instructions for treatment; if the retest is normal, they should have their blood pressure checked regularly.
