"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. " - High afterload
