WebOct 16, 2024 · Mean arterial pressure best estimates this. Also, afterload can be estimated by the minimum amount of pressure needed to open the aortic valve, which is equivalent to the diastolic pressure. Thus, diastolic blood pressure is one of the better ways to index afterload. Finally, the ejection fraction (EF) is equal to SV/EDV.

Web88. The Frank-Starling principle relates more to preload than to afterload. As preload increases, the ventricles contract more forcefully and stoke volume increases. 89.
