Blood pressure is an important parameter that reflects the functioning of the body's cardiovascular system. It is defined as the difference between systolic and diastolic pressure. Systolic pressure reflects the change in pressure within a vessel during the cardiac cycle, while diastolic pressure reflects the pressure that is exerted on the vessel walls at the end of each cardiac cycle.
Diastolic blood pressure characterizes the patient's state at rest, when the heart is in a relaxed state and the vessels are free of blood flow. This pressure is characterized by two parameters: upper (systolic) and lower (diastolic).
The upper indicator, systolic, reflects the filling of the arteries with blood during the contraction of the heart - systole, while the lower one, diastole, characterizes the pressure in the vessels during the relaxation phase. If a person has normal diastolic pressure (less than 80 mm Hg), this may mean that he has no problems with the condition of the blood vessels and heart, but if it is elevated, this may
