Jul 2, 2024 · Afterload is a fancy word for the pressure required for the left ventricle to force blood out of the body to exert during systole. In other words, it’s the effort of the ventricle squeezing.

Afterload is largely dependent upon aortic pressure. Afterload is the pressure that the heart must work against to eject blood during systole (ventricular contraction).

Afterload can be thought of as the "load" that the heart must eject blood against. In simple terms, the afterload of the left ventricle is closely related to the aortic pressure.

Sep 3, 2025 · Increased afterload (e.g., hypertension, aortic stenosis) forces the heart to work harder. Decreased afterload (e.g., vasodilation, septic shock) reduces cardiac workload.

Dec 28, 2023 · Cardiac afterload is the pressure that the ventricles have to generate in order to pump the blood out of semilunar valves. The pressure in the aorta is approximately 80 mmHg and the …

Afterload = left ventricular wall tension required to overcome resistance to ejection (impedance to ejection of blood from the heart into the arterial circulation).

Apr 24, 2023 · The afterload is the amount of pressure that the heart needs to exert to eject the blood during ventricular contraction. This is recorded as the systolic pressure of the heart.

Aug 30, 2025 · Afterload refers to the resistance the heart must overcome to eject blood into the circulatory system. The heart must generate sufficient pressure to exceed this resistance before …

The afterload on the heart is all about arterial pressure, or the pressure of the arterial system that the left ventricle (LV) must pump against during each contraction. Afterload can be estimated by mean …

Apr 28, 2020 · "Afterload is the resistance to ventricular ejection - the "load" that the heart must eject blood against and is related to ventricular wall stress (Law of Laplace, T=Pt.r/u)"
