![]() 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 the (higher) systolic blood pressure minus the (lower) 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.
