High blood pressure in hypertension is mainly related to the following reasons: 1. Increased heart rate. The patient’s heart rate increases after the systolic period of the heart is relatively longer and the diastolic period is relatively shorter, so the heart can easily shoot more blood into the aorta per unit time, which increases the amount of blood held in the aorta and causes an increase in low pressure. 2. The peripheral vascular resistance increases. In this case, the resistance of blood flow in the aorta to the periphery will increase, and the amount of blood flowing to the periphery will be reduced accordingly, and more blood will remain in the aorta, thus causing an increase in diastolic blood pressure. 3. Bad habits of life. The most common are patients who are nervous, stay up late, anxious, sleep deprived and mentally stressed, and if there is a lack of physical exercise, these bad habits are very detrimental to the control of blood pressure and can easily cause an increase in low pressure in patients.
