The survival of hypertensive patients is related to the level of the patient’s blood pressure, the patient’s compliance with treatment and the presence of target organ damage and complications. Hypertension is a systemic chronic disease that causes damage to target organs throughout the body, especially the heart, kidneys and brain, but within a certain fluctuation range of blood pressure, the organs of the body have a certain compensatory capacity and regulatory ability. Therefore when the patient’s blood pressure value is not elevated to a large extent, and the patient regularly takes antihypertensive drugs to control the blood pressure within the normal range, it will not affect the patient’s life expectancy. However, if the patient’s blood pressure is high and also not controlled, or if target organ damage occurs, serious complications may occur and endanger the patient’s life. In conclusion, patients should seek medical consultation once they find elevated blood pressure and take antihypertensive drugs according to the regular lifelong schedule to avoid complications.
