If a hypertensive patient’s blood pressure suddenly rises to 180 mmHg, the first step is to clarify whether the blood pressure is measured regularly, and if so, the blood pressure has a reference value. Secondly, it is necessary to exclude the trigger of hypertension, such as whether the blood pressure was measured during emotional excitement or exercise. If the high pressure is still 180 mmHg, according to the risk stratification assessment of blood pressure classification, the patient belongs to grade 3 hypertension, which is a high-risk or very high-risk patient, that is, the patient is at a higher risk of cardiovascular adverse events. There is a risk of angina pectoris, myocardial infarction, acute heart failure or cerebral hemorrhage or cerebral infarction. Especially in patients with aortic coarctation, it is important to prevent the serious consequences of ruptured aortic coarctation and bleeding. If the blood pressure is suddenly increased to 180 mmHg and accompanied by severe headache, chest tightness and other symptoms, or the patient himself is also relatively nervous, such patients are recommended to go to the hospital to lower the blood pressure treatment, if necessary, but also to do electrocardiogram, head CT and other related tests to prevent the occurrence of adverse cardiovascular events. If it is because the systolic blood pressure is usually high in elderly hypertensive patients, high pressure from 160mmHg to 180mmHg, and the patient does not have any uncomfortable symptoms, you can lower the blood pressure by oral antihypertensive drugs or oral usual antihypertensive drugs, not necessarily immediately go to the hospital, but pay attention to blood pressure monitoring, take the medication on time. It is recommended to use 1-2 long-acting antihypertensive drugs, and at the same time to adhere to a good lifestyle, maintain a normal weight, also need to control blood lipids, and keep the body and mind happy.
