August undefined, 2024

WebIt is related to ventricular filling. Afterload is the force or load against which the heart has to contract to eject the blood. Contractility is the intrinsic strength of the cardiac muscle independent of preload, but a change in preload will affect the force of contraction. Afterload is the ‘load’ to which the heart must pump against. 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.
