The direct relationship between preload and cardiac output was formulated in the early 1900s based on the work of Otto Frank and Ernest Starling.

The Frank–Starling law of the heart (also known as Starling's law and the Frank–Starling mechanism) represents the relationship between stroke volume and end diastolic volume. The law states that the stroke volume of the heart increases in response to an increase in the volume of blood in the ventricles, before contraction (the end diastolic volume), when all other factors remain constant.

Preload, with our understanding of exactly what it. is, it’s essentially affected by volume – how much volume you have going through the. system and how well that volume is able to move; that’s going to affect your preload. Afterload is also affected by volume but even more directly it’s affected by Afterload.

Afterload is the 'load' to which the heart must pump against. Afterload goes down when aortic pressure and systemic … Weirdly, afterload seems to be the favourite, in case the time-poor candidate is so poor that they only have time to study one determinant of cardiac output to the exclusion of the others.
