1 doctor agrees

In brief: Many thinks

Heart failure can lead to decreased output which can occur for a variety of reasons, the major one being a heart attack.
Very slow heart rate can also lead to a decreased co which is the product of stroke volume and heat rate.

Cardiac output= heart rate X stroke volume. Therefore if your stroke volume decreases and or your heart rate decreases your cardiac output will decrease. The stroke volume may decrease because of hypovolemia or organic heart disease.

In brief: Only four things

1) afterload (high BP or stiff valves) - the heart is pushing blood against a tougher obstacle 2) preload (sepsis, shock or dehydration) - not enough blood to pump 3) low hr (less beats total) 4) low inotropy (heart failure, heart attack, or inflammation) - the heart squeezes less forcefully with each beat.
Ok - a bonus 5th - shunt: the heart swirls blood around w/o it going anywhere.
