Grade 2 hypertension is defined as blood pressure with systolic blood pressure in the range of 160-179mmHg or diastolic blood pressure in the range of 100-109mmHg. Grade 2 hypertension is also known as moderate hypertension, and simple lifestyle control for patients with grade 2 hypertension is generally not able to restore the blood pressure to the normal level. Therefore, on top of lifestyle modification, it is necessary to choose appropriate blood pressure-lowering drugs to effectively regulate blood pressure. Some patients also need to use different antihypertensive drugs for joint antihypertensive treatment, in order to make the blood pressure control standard, and long-term stabilization of blood pressure. If the patient is also accompanied by related cardiovascular risk factors, such as high blood sugar, high blood fat, etc., also need to carry out long-term effective control.
