Hypertensive patients should not only be graded but also stratified, the stratification is based on the following: 1, age, if men > 55 years old, women > 65 years old, is a risk factor; 2, adverse family history, adverse family history refers to the early onset of cardiovascular disease, such as one or both parents of the patient has been diagnosed with coronary heart disease before the age of 45, that is, a poor family history; 3, hypercholesterolemia creatinine value increased, thickening of the carotid intima, left ventricular myocardial hypertrophy found by cardiac ultrasound, and sclerosis of the fundic arteries found are all target organ damage and are part of the risk stratification; 4. Already complicating diabetes mellitus, complicating coronary artery disease, and complicating hyperlipidemia are all part of the risk stratification. Patients with complications are generally part of the very high risk group for grade 3 hypertension, and if there is only one risk factor possible or no risk factor, they are part of the low risk group. The treatment is different for the different groups. If the patient is only in the low risk group of grade 1 hypertension, the patient may be asked to improve his or her poor lifestyle and regular review is sufficient. For the very high risk group of hypertension grade 3, regular medication, close monitoring of blood pressure changes, close monitoring of target organ damage, as well as a physical examination usually within six months, monthly follow-up examinations, and help from the doctor to find risk factors, while keeping the risk situation under control in the cradle state to prevent further target organ damage and further aggravation of complications.
