What do systolic and diastolic blood pressure mean?
Disease description:
Recently, our company organized a physical examination. After receiving the examination report, I noticed that it listed “systolic blood pressure” and “diastolic blood pressure.” Could you please explain what these terms mean?

Systolic blood pressure refers to the lateral pressure exerted by blood flow and blood components themselves against the arterial wall during cardiac contraction, whereas diastolic blood pressure refers to the lateral pressure exerted against the arterial wall by hemodynamics and blood components during cardiac relaxation. In healthy adults, normal systolic blood pressure ranges from 90 to 140 mmHg, and normal diastolic blood pressure typically ranges from 60 to 90 mmHg. Among individuals with hypertension, most exhibit elevations in both systolic and diastolic pressures to varying degrees; however, some patients may present with isolated systolic hypertension (elevated systolic pressure only). Both conditions are harmful to the body.
