Under normal circumstances, blood pressure should be <140mmHg systolic and <90mmHg diastolic. when the blood pressure is 160/110mmHg, it is a level 3 hypertension, but whether it is a dangerous situation should also be seen in the context of whether the patient has underlying disease and the duration of hypertension. When the blood pressure is 160/110 mmHg, it may be a transient elevation, such as due to emotional stress and anxiety, usually without underlying disease, and can be reduced to a normal level by adjusting emotions and relieving anxiety, and is generally not a dangerous condition. For patients with long-term blood pressure at 160/110 mmHg, the situation is more serious and can lead to certain damage to the heart, brain, kidneys, eyes and other target organs. Increased creatinine and the presence of urinary protein are seen on examination when the kidneys are damaged. The progression of the disease can cause fundus lesions, such as fundus arteriosclerosis, fundus hemorrhage and optic papilloedema, as well as increase the risk of serious cardiovascular and cerebrovascular diseases in patients, such as coronary artery disease, cerebral hemorrhage, acute heart attack, cerebral infarction, and even heart failure, when the situation is more dangerous and timely interventions should be taken to avoid adverse effects. Therefore, when there is an increase in blood pressure, the cause should be clarified in a timely manner, relieve tension, seek medical attention in a timely manner, and take antihypertensive drugs under the guidance of a doctor to keep blood pressure within the ideal range and reduce the chance of cardiovascular disease.
