We all know that a normal person’s blood pressure will fluctuate slightly throughout the day, especially in the morning or at noon, and these fluctuations are more significant. However, as long as these fluctuations are within a certain range, they are normal and will not have any impact on the body. However, if the blood pressure difference is too high, the resulting harm should not be ignored. But what kind of harm does a large blood pressure difference cause?

What causes a large blood pressure difference?

Under normal circumstances, the pulse pressure difference of an average person is 20~60mmHg (2.67~8.0Kpa), and one greater than 60mmHg is considered to be an excessive pulse pressure difference, while one less than 20mmHg is considered to be too small. The main causes of an excessive pulse pressure difference include: (1) Hypertension and arteriosclerosis, leading to weakened elasticity of the aortic wall, increased systolic pressure, and decreased diastolic pressure; (2) Long-term hypertension, leading to overloading of the heart, causing heart dilation or valve insufficiency; (3) Hyperthyroidism or severe anemia.

What kind of harm does a large blood pressure difference cause?

Blood pressure refers to the pressure exerted on the outer wall of the blood vessels when blood flows. Blood pressure is divided into systolic pressure and diastolic pressure, and the pulse pressure difference refers to the difference between systolic and diastolic pressure, which is generally defined as 30 to 40mmHg in clinical medicine.

Generally, a pulse pressure difference greater than 60mmHg is called an increased pulse pressure difference, and a pulse pressure difference less than 20mmHg is called a decreased pulse pressure difference. In other words, the normal pulse pressure difference for an average person is 20 to 60mmHg (2.67 to 8.0Kpa), and a pulse pressure difference less than 20mmHg is called a decreased pulse pressure difference, while one greater than 60mmHg is considered to be an excessive pulse pressure difference. The pulse pressure difference is a key indicator of the elasticity of the aorta, and with the increase in age, the aorta gradually loses elasticity, resulting in a significant increase in systolic pressure and a significant decrease in diastolic pressure, with a significant increase in pulse pressure difference.

A large pulse pressure difference is a major manifestation of arteriosclerosis. An increased pulse pressure difference indicates poor elasticity of the aorta, that is, the structure and function of the aortic wall are damaged, and the wall becomes hard. A pulse pressure difference of 85mmHg is more than 10% higher than that of 65mmHg in terms of the risk factors for myocardial infarction and stroke, with the former having a significantly higher probability of cerebrovascular accidents than the latter.

This is what might happen when the blood pressure difference is too high, and these injuries are all relatively severe. Therefore, when the blood pressure difference is too high, everyone should not ignore it and should pay attention to their own health to prevent problems from occurring without knowing them. Also, in everyday life, it is necessary to enhance physical fitness and improve one’s own body.
