Meaning of the Term Afterload. Although the concept of afterload is used on a daily basis by clinicians (eg, âafterload reduction during treatment of heart failureâ), it is unclear what the term really means and how to accurately measure it.he aforementioned afterload concepts and principles apply to both the systemic and the pulmonary circulation. Because the right and left heart are constructed in series, they necessarily transport the same amount of blood and thus have the same cardiac output in the absence of a shunt.
The other three processes are preload (the pressure of the blood on the heart muscle fibers), contractility (the force of the contraction), and heart rate. To have more cardiac output you have to have lower afterload. Stroke volume is the actual contraction of the muscle fibers that eject the blood from the heart.
