Question

Quizplus · Accepted Answer

As we age, there is a gradual decline in cardiac function, which results in a decrease in the amount of blood that the heart can pump with each beat, known as stroke volume. This decrease in stroke volume is reflected in the stroke volume index, which is calculated as stroke volume divided by body surface area. Therefore, both stroke volume and stroke volume index are diminished with aging.
