Pulse Pressure Essay
The pulse pressure is the difference between the systolic and diastolic pressure. The systolic or top pressure is defined as the amount of pressure exerted on the blood vessels when the ventricle is contract (systole). The pressure is due to the force produced as the blood is ejected contacted with the blood vessel’s wall. On the other hand, the diastolic or bottom pressure is defined as the amount of pressure of the blood vessels when the heart is at rest (diastole).
A) Pulse pressure
In simplest words, the pulse pressure can be explained as the amount of pressure when the systolic pressure minus diastolic pressure. The unit is in mmHg. As per theory, the pulse pressure is proportional to stroke volume, or the total amount of the blood ejected by the left ventricle …show more content…
During exercise, the heart works very hard to supply more oxygen to the body. In return, the cardiac output is higher and eventually it will increase the pulse pressure. But in some cases, there’s a condition where the pulse pressure is high even at rest condition. In this case, something is not right with the heart condition. This condition may be due to the stiffness of the major arteries. An example is atherosclerosis (hardening of blood vessel’s wall).
The major determinant of the pulse pressure is the aortic compliance and also the stroke volume. The aortic compliance is the ability of the aorta to expand once the blood is ejected to the aorta by the ventricle. The more compliant the aorta, the smaller the pressure change during the ventricular ejection/contraction/systole. Therefore, the smaller the pulse pressure. The wide or high pulse pressure is having a risk of heart disease. The person that having an elevated pulse pressure must seeks for a medical treatment. Among the treatment for high pulse pressure is angiotensin-converting enzyme (ACE)
