High diastolic blood pressure measured while standing in a person who stood up shortly after waking up. When it affects an individual's ability to remain upright, orthostatic hypertension is considered as a form of orthostatic intolerance. The body's inability to regulate blood pressure can be a type of dysautonomia.
One response is a vasoconstriction (baroreceptor reflex), pressing the blood up into the body again. (Often, this mechanism is exaggerated and is why diastolic blood pressure is a bit higher when a person is standing up, compared to a person in the horizontal position.) Therefore, some factor that inhibits one of these responses and causes a ...
The rate of mean blood flow depends on both blood pressure and the resistance to flow presented by the blood vessels. In the absence of hydrostatic effects (e.g. standing), mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy.
Greek yogurt on its own is a great choice for your heart. But when you add the power of fruit and nuts, the nutritional benefits of this snack increase exponentially. For starters, Greek yogurt is ...
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.

An important relationship between systolic and diastolic function is the Frank-Starling mechanism, which basically shows that loading up the ventricle with blood during diastole and stretching out the cardiac muscle makes it contract with more force, which increases stroke volume during systole.
