This allows direct comparison of the stroke volume index of large and small patients. Stroke volume index is determined by three factors: Preload: The filling pressure of the heart at the end of diastole. Contractility: The inherent vigor of contraction of the heart muscles during systole. Afterload: The pressure against which the heart must work to eject blood during systole. Starling's Law is the relationship between preload and stroke volume .
Stroke volume is intrinsically controlled by preload (the degree to which the ventricles are stretched prior to contracting). An increase in the volume or speed of venous return will increase preload and, through the FrankâStarling law of the heart, will increase stroke volume. Decreased venous return has the opposite effect, causing a reduction in stroke volume.
