What is pulse pressure?

Pulse pressure is defined as the difference between systolic and diastolic blood pressure. Systolic pressure is the force exerted against the arterial walls during heartbeats, while diastolic pressure is the force during the resting phase between heartbeats. This difference is significant because it provides insight into the health and elasticity of the arteries. A normal pulse pressure can suggest adequate blood flow and overall cardiovascular health.

For instance, if a person has a systolic blood pressure of 120 mmHg and a diastolic blood pressure of 80 mmHg, the pulse pressure would be 40 mmHg (120 - 80). An elevated pulse pressure may indicate stiffness of the arteries, while a low pulse pressure could suggest poor heart function or diminished cardiac output.

Understanding pulse pressure is crucial in cardiovascular assessment, as it can help healthcare professionals evaluate a patient’s risk for conditions like hypertension and other heart diseases.
