The high-risk group for hypertension first depends on the patient’s own blood pressure. Generally speaking, a hypertensive patient with a high pressure greater than 159 mmHg and a low pressure greater than 100 mmHg is in the moderate to high risk group. If the high pressure is greater than 180 mmHg and the low pressure is greater than 110 mmHg, it is a very high case. Including the combination of some complications, such as coronary heart disease, diabetes, cardiovascular disease, cerebral infarction, these are the criteria for diagnosing high risk group of hypertension. Such patients may have some cardiovascular diseases or even cerebral hemorrhage at any time and anywhere. Therefore, once hypertension is detected, it is important to actively and regularly take relevant oral antihypertensive drugs to maintain blood pressure to a relatively stable state, which is conducive to the prevention of cardiovascular and cerebrovascular diseases. Normally, a low salt and low fat diet should be taken to help reduce hypertension and reduce the pressure load on the heart, brain and kidneys.
