Hypertension with a systolic blood pressure of 220mmHg is classified as grade 3 hypertension, and it is not clear how long you can live, but you should actively treat it and keep your blood pressure within the normal range. In the resting state, the normal range of systolic blood pressure in adults is 90~139mmHg, and the normal range of diastolic blood pressure is 60~89mmHg, while the systolic blood pressure of 220mmHg belongs to grade 3 hypertension, which is a more serious form of hypertension. It needs to be lowered immediately, and commonly used drugs include perindopril, irbesartan, bisoprolol, nifedipine extended-release tablets and so on. However, because the measurement of blood pressure is affected by many factors, such as heart rate, vascular resistance, vascular volume, etc., the phenomenon of increased blood pressure can occur after tension, strenuous exercise, and may also be secondary hypertension. If the blood pressure is as high as 220 mmHg by chance and quickly returns to normal after rest, no special effects are needed. However, if the blood pressure is persistently or frequently as high as 220mmHg, damage to organs such as the heart, brain, kidneys and fundus of the eye may occur, and in severe cases, acute cardiovascular and cerebrovascular events may occur. When the high blood pressure is 220mmHg, it is recommended to consult a doctor immediately to find out the cause and treat it actively under the guidance of a physician.
