WebThe arterial pulse pressure (the difference between the systolic and the preceding diastolic pressure) is directly proportional to stroke volume and inversely related to arterial compliance. 47 Therefore, for a given arterial compliance, the amplitude of pulse pressure is directly related to left ventricular stroke volume. WebAs pulse pressure rises above the normal of 40 mmHg, the risk of problems with your heart and blood vessels goes up, even with small increases. Pulse pressures of 50 mmHg or more can increase your risk of heart disease, heart rhythm disorders, stroke and more.
