WebPreload and afterload are intimately related. When LV preload is increased in a normal heart, systolic LV pressures generally increase, and as a result systolic wall stress … WebAfterload is the pressure against which the heart must work to eject blood during systole (systolic pressure). The lower the afterload, the more blood the heart will eject with each contraction. Like contractility, changes in afterload will raise or lower the Starling curve relating stroke volume index to LAP. hannity texts jan 6WebPreload: An increase in preload increases cardiac output by increasing the force of contraction, resulting in an increase in stroke volume. However, there is an optimal level of preload beyond which further increases result in decreased cardiac output due to excessive stretch of the heart muscle. posthumanistyka
