A blood pressure of 142 mmHg is above normal, both diastolic and systolic blood pressure of 142 mmHg are above the normal range. The normal range of blood pressure is within 140/90mmHg. Hypertension is diagnosed when the systolic blood pressure exceeds 140mmHg and/or the diastolic blood pressure exceeds 90mmHg in three measurements not taken on the same day. Systolic blood pressure of 142mmHg is mildly elevated, and if it is not combined with cardiovascular and cerebrovascular diseases, diabetes and other risk factors, it can be treated by adjusting lifestyle habits first, such as avoiding late nights, low-salt and low-fat diets, etc. However, if it is combined with risk factors, it is necessary to take antihypertensive medications, such as valsartan, to treat it. Diastolic blood pressure of 142mmHg belongs to the category of hypertension level 3, patients have a greater possibility of cerebral hemorrhage and other cardiovascular emergencies, so you need to go to the hospital in time for antihypertensive treatment, such as calcium antagonist nifedipine or uradil and other medications, and if necessary, can be intravenously injected with nitroglycerin for treatment.
