The severity of the disease cannot be judged solely on the basis of the level of blood pressure, but needs to be assessed in conjunction with the patient’s symptoms, the presence or absence of target organ damage and many other factors. A blood pressure of 158 mmHg is considered to be grade 1 hypertension, and most patients do not have obvious clinical symptoms such as dizziness and headache, which will not have a significant impact on their life and work. If the patient does not have liver function and renal function damage, heart enlargement, cardiac insufficiency and other target organ damage, the assessment at this time is milder, first of all, should be a low-salt and low-fat diet and increase exercise, oral antihypertensive medication, if necessary, to control the blood pressure within the ideal range. If hypertensive patients can smoothly control their blood pressure within the ideal range after oral antihypertensive drug therapy, the probability of target organ damage, such as liver function damage and hypertensive nephropathy, will be reduced, and the patient’s condition is assessed to be milder at this time. If blood pressure fluctuates or rises further after antihypertensive treatment, the probability of target organ damage may increase, and the condition of such patients is relatively severe. If hypertensive nephropathy, coronary atherosclerosis and other related complications have already occurred when the patient is found to be hypertensive, the condition is more serious, antihypertensive treatment is still the key to treatment, and it is also necessary to treat the complications that have already occurred to avoid further progression of the condition of these complications. It is recommended that the patient go to the cardiovascular department in time to improve the relevant examination to clarify whether it is primary hypertension or secondary hypertension, and according to the patient’s condition to formulate the appropriate antihypertensive program for antihypertensive treatment, and dynamic monitoring of blood pressure changes.
