Cardiac reserve

Cardiac reserve refers to the difference between the rate at which the heart pumps blood and its maximum capacity for pumping blood at any given time. A measurement of the cardiac reserve may be a health indicator for some medical conditions. Cardiac reserve may be 4-5 times greater than a resting value for a healthy person.

Measurements

Cardiac reserve has been measured in different ways over the history of the test.[1]

It is possible to make a non-invasive measurement of cardiac reserve.[2]

Significance

A measure of cardiac reserve can help predict the likelihood of heart failure when indicated.[3]
