Systolic blood pressure, also known as high pressure, if 160 mmHg, and diastolic blood pressure, also known as low pressure, if 120 mmHg, are abnormal and are considered to be hypertension. For further clarification of hypertension, it is recommended that ambulatory blood pressure monitoring be done, or that blood pressure be measured three times on non-simultaneous days. For the patients who found hypertension for the first time, it is better to do another examination of secondary factors that trigger hypertension, such as adrenal CT, renal vascular ultrasound, craniocerebral CT, hypertension six, renal function, liver function, blood glucose, and these related lab tests, which can help to further clarify, whether the type of hypertension is secondary hypertension or not. If it is primary hypertension, it is necessary to take antihypertensive drugs for a long time and for life, so that the blood pressure can be controlled within the standard range and the emergence of hypertension complications can be delayed.
