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.

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 …

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.

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.

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

Dec 3, 2025 · Afterload represents the pressure or load that the ventricles must overcome to eject blood into the major arteries during contraction, or systole. This resistance is encountered as the heart …

Aug 30, 2023 · The main difference between preload and afterload is that preload is the pressure that occurs at the initial stretching of the cardiac myocytes, whereas afterload is the force that occurs …

Jul 2, 2025 · Afterload refers to the resistance or "load" that the heart must overcome to eject blood into the systemic circulation during systole 3. It is defined as all of the factors that contribute to total …
