A blood pressure of 150 mmHg is not necessarily serious by itself; further risk stratification of blood pressure needs to be conducted. If the risk stratification of blood pressure is high or very high, the condition is relatively serious and active antihypertensive treatment is necessary to effectively reduce the future risk of cardiovascular and cerebrovascular events, thus improving the patient's prognosis. If the blood pressure of 150 mmHg is classified as low or medium risk, this level of blood pressure is not serious, but it still requires long-term standardized treatment to control the blood pressure to the target level. If blood pressure is not well controlled, long-term hypertension can gradually make the condition very serious, increase the risk stratification, and significantly raise the likelihood of cardiovascular and cerebrovascular events.
