Mild hypertension patients should be stratified according to the risk factors of hypertension, whether there is damage to target organs, whether there are complications, and whether there is diabetes. For high-risk or very high-risk patients, antihypertensive treatment or even combined antihypertensive treatment can be used at the beginning. Five categories of commonly used antihypertensive drugs can be selected in clinical practice, for example, the representative drugs of ACEI are benazepril, and the representative drugs of beta blockers are metoprolol and bisoprolol, The representative drugs of CCB are nifedipine controlled release tablets and amlodipine, and the representative drugs of diuretics are indapamide and hydrochlorothiazide, which can be used first by a single drug. If not, apply it jointly. If the patient has mild hypertension, is a low-risk or moderate risk patient, he can temporarily not use antihypertensive drugs to improve his lifestyle, and observe for 1-3 months. If the blood pressure is still difficult to control to the normal range, use antihypertensive drugs.
