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 also affected by the body's demand for oxygen, delivery of nutrients to the muscles and tissues and the removal of toxins, explains Cheetah Medical. For example, exercise increases the demand for oxygen, which results in a faster heart rate and increased stroke volume. People with a high level of cardiovascular fitness have larger stroke volumes and lower heart rates at rest than people who have a lower level of cardiovascular fitness.
