Stroke volume is inversely correlated to preload; i.e., a lower preload increases stroke volume.

Stroke volume is directly related to preload, meaning that a higher preload leads to a higher stroke volume. This is because preload refers to the amount of blood filling the heart before it contracts, and a greater volume of blood provides more stretch on the heart muscle, allowing for a stronger contraction and a larger stroke volume.
