The factor that would NOT increase cardiac output is "increased blood concentration of glucose".

Here's why:

a. Increased venous return: This would increase cardiac output because the more blood that returns to the heart, the more blood the heart can pump out.

b. Decreased parasympathetic stimulation of the heart: The parasympathetic nervous system slows the heart rate. So, decreasing its stimulation would result in an increased heart rate and thus increased cardiac output.

c. Increased sympathetic stimulation of the heart: The sympathetic nervous system increases the heart rate. So, increasing its stimulation would also result in an increased heart rate and thus increased cardiac output.

d. Increased blood concentration of glucose: This would not directly affect cardiac output. While it's true that the heart needs glucose for energy, an increase in blood glucose concentration doesn't necessarily mean the heart will pump more blood.

e. Stimulation of the heart by epinephrine: Epinephrine (also known as adrenaline) increases heart rate and the force of heart contractions, both of which would increase cardiac output.
