Afterload

Afterload per se does not alter preload; however, preload changes secondarily to changes in afterload. Increasing afterload not only reduces stroke volume, but it also increases left ventricular end-diastolic pressure (LVEDP) (i.e., increases preload). Afterload is the ‘load’ to which the heart must pump against. Afterload goes down when aortic pressure and systemic vascular resistance decreases through vasodilation. Decreasing afterload will affect the Doppler numbers in a number of ways. Peak velocity (PV) may increrase as the heart finds it easier to pump against decreasing pressures. Afterload Afterload, also known as the systemic vascular resistance (SVR), is the amount of resistance the heart must overcome to open the aortic valve and push the blood volume out into the systemic circulation.

Medical Definition of afterload : the force against which a ventricle contracts that is contributed to by the vascular resistance especially of the arteries and by the physical characteristics (as mass and viscosity) of the blood Learn More about afterload Dictionary Entries near afterload Afterload is a concept of the work or pressure needed by the ventricle to eject blood out of the semilunar valve. The most common influence on afterload is the vascular tone or resistance to blood flow. But other factors, such as stenosis of the semilunar valve or viscosity of blood, may also affect afterload.
