WebAug 27, 2024 · Your afterload will also increase, often in an attempt to increase your blood pressure by tightening your blood vessels. What factors increase afterload? Afterload is … WebBriefly, an increase in venous return to the heart increases the filled volume (EDV) of the ventricle, which stretches the muscle fibers, increasing their preload. This leads to an increase in the force of ventricular contraction and enables the heart to eject the additional blood that was returned to it.

Preload, afterload, and cardiac contractility are important factors that influence cardiac function. Preload: Preload is the amount of tension or stretch applied to the myocardium (heart muscle) before contraction. It is determined by the volume of blood in the ventricle at the end of diastole, just before contraction.
