![]() ![]() This serves to dampen the pulsatile ( maximum pumping pressure) of the left ventricle, thereby reducing the initial systolic pulse pressure, but slightly raising the subsequent diastolic phase. The aorta has the highest compliance in the arterial system due in part to a relatively greater proportion of elastin fibers versus smooth muscle and collagen. 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. Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. Clinicians consider a pulse pressure of 60 mmHg to likely be associated with diseases, with a pulse pressure of 50 mmHg or more increasing the risk of cardiovascular disease. It represents the force that the heart generates each time it contracts. It is measured in millimeters of mercury (mmHg). ![]() Pulse pressure is the difference between systolic and diastolic blood pressure. ![]()
