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. If you think about the balloon analogy, afterload is represented by the knot at the end of the balloon. - Afterload: Motsvaras av den tension som hjärtmuskeln måste uppbåda under kontraktionen.
Following Laplace’s law, the tension upon the muscle fibers in the heart wall is the product of the pressure within the ventricle and the ventricle radius, divided by the ventricle wall thickness. Preload, in addition to afterload and contractility, is one of the three main factors that directly influence stroke volume (SV), the amount of blood pumped out of the heart in one cardiac cycle. Affected by changes in venous tone and circulating blood volume, changes in preload directly affect stroke volume, therefore influencing cardiac output and the overall function of the heart.

En ökad afterload ger en minskad slagvolym. Detta är t ex fallet vid hypertoni. Ejektionsfraktion inducerade vasokonstriktionen (ökning av afterload).
Like contractility, changes in afterload will raise or lower the Starling curve relating stroke volume index to LAP.
Cardiac afterload is one of the main factors that influence how much blood the heart pumps out with each heartbeat, or stroke.. Now, remember that the heart has two upper chambers: the left atrium, which receives oxygenated blood from the lungs via the pulmonary veins; and the right atrium, which receives deoxygenated blood from all of our organs and tissues via the superior and inferior vena
Afterload = “LV wall stress during ejection”. Unlike preload which is the wall stress at a specific point in time, the afterload is the LV wall stress during a period of time (ejection).

afterload is the resistance that the ventricle must overcome during systole in order to eject a stroke volume. (2). This concept thus implies that the heart is a pump. 9 Feb 2021 The systolic performance of the heart is determined by 3 factors: preload, afterload, and contractility.

Applying this definition to the heart, afterload can be most easily described as the "load" against which the heart ejects blood. Pre-, en afterload zijn termen die te maken hebben met de belasting van het hart tijdens de diastolische en systolische fase.Preload is de voorbelasting en a Afterload is the degree of pressure inside the aorta to overcome the push of blood. Afterload is just a fancy term for how much pressure the ventricles need to exert during systole.
