The systolic pressure of the heart is the pressure in the arteries that reaches its maximum in the middle of ventricular systole, when the pressure of the blood against the inner walls of the blood vessels, and the diastolic pressure of the heart is the blood pressure when the arterial blood pressure reaches its minimum at the end of ventricular diastole. In general, the normal range of systolic blood pressure is 90 to 140 mmHg, and the normal range of systolic blood pressure is 60 to 90 mmHg. There are individual, age and gender differences in cardiac systolic and diastolic blood pressure. Blood pressure tends to increase gradually with age and is more pronounced in systolic than in diastolic blood pressure. Women’s blood pressure is slightly lower than that of men of the same age before menopause. Elevated systolic and diastolic blood pressure values can lead to hypertensive disorders, causing cardiovascular and cerebrovascular complications; low blood pressure can also lead to tissue and organ hypoperfusion, causing symptoms such as dizziness, black haze, and renal insufficiency. Therefore, patients with abnormal systolic or diastolic blood pressure should go to the hospital in time and be treated as soon as possible under the doctor’s guidance.
