A high pressure of 140 mmHg is not in the normal blood pressure range and is classified as first-degree hypertension. High pressure is systolic blood pressure. The main intervention for Grade 1 hypertension is lifestyle control of blood pressure, with the addition of antihypertensive medication if this is not effective. Normal blood pressure is defined as systolic blood pressure <140mmHg and/or diastolic blood pressure <90mmHg, and grade 1 hypertension is defined as systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg more than three times on the same day. 140mmHg systolic blood pressure does not belong to the range of normal blood pressure, but belongs to the range of grade 1 hypertension, and therefore belongs to grade 1 hypertension. The treatment of Grade 1 hypertension mainly focuses on lifestyle intervention, including light diet, less food containing fat and sodium, more vegetables and fruits, moderate increase in exercise, avoiding obesity, quitting smoking and limiting alcohol consumption, reducing mental stress, and ensuring a good state of mind, etc. If the blood pressure is still low after the intervention, the patient should be treated with a standardized treatment. If the blood pressure does not decrease or even increase after lifestyle intervention, the application of antihypertensive drugs should be increased under the guidance of the doctor. Commonly used antihypertensive drugs include calcium receptor antagonists (nifedipine, amlodipine), angiotensinase inhibitors or portable inhibitors (captopril, perindopril, chlosartan, valsartan), diuretics (furosemide, hydrochlorothiazide), β-blockers (bisoprolol, metoprolol) and so on. If abnormal blood pressure is detected, early medical consultation is recommended to avoid delaying the condition.
