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.
An arteriovenous fistula can increase preload. AV shunts also decrease the afterload of the heart. This is because the blood bypasses the arterioles which results in a decrease in the total peripheral resistance (TPR). AV shunts increase both the rate and volume of blood returning to the heart.
