150/100mmHg is classified as grade 2 hypertension, also called moderate hypertension. For patients with hypertension, in addition to the blood pressure level, it is more important that the risk stratification of hypertension has a more important role in the patient’s prognosis. If a patient’s risk stratification is very high risk, even if only hypertension grade 1 is serious, his or her risk of future cardiovascular and cerebrovascular events is significantly higher. Therefore, patients with grade 2 hypertension need to be treated with antihypertensive drugs, and the strategy of antihypertensive treatment should be decided according to the patient’s risk stratification, and the higher the risk stratification, the more stringent the control of the blood pressure level should be. Especially for patients with coronary heart disease, diabetes mellitus and renal impairment, the antihypertensive target should be controlled below 130/80mmHg.
