WebAnswered by aliziam22. 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.
