What does arterial systolic blood pressure mainly reflect?

Generally, arterial systolic pressure primarily reflects the maximum pressure generated by the left ventricle during contraction.

Under normal conditions, aortic pressure usually remains between 90 mmHg and 140 mmHg. If arterial systolic pressure is relatively low, it typically indicates reduced pumping capacity of the left ventricle, which may lead to insufficient blood supply to the heart and brain, causing ischemia or hypoxia in cardiac organs. This can result in symptoms such as recurrent headaches, dizziness, or tinnitus. Conversely, if arterial pressure is excessively high, it may cause compression of the aorta and even contribute to aortic hardening.

When aortic pressure becomes abnormal, it is advisable to seek medical evaluation at a hospital as early as possible to assess the severity of the condition. During targeted treatment, it's important to adjust dietary habits and lifestyle—focusing on a low-sugar, low-salt, and low-fat diet, avoiding strenuous exercise, and getting appropriate sun exposure and aerobic activities outdoors to enhance overall immunity.
