Question

which of the following is associated with the development of a high output cardiac failure?
anemia
congestive cardiomyopathy
ischemic heart disease
myocarditis

Explanation:

High - output cardiac failure occurs when the heart has to pump an increased amount of blood. Anemia leads to a decrease in the oxygen - carrying capacity of the blood. To meet the oxygen demands of the body, the heart has to pump more blood (increased cardiac output initially). Over time, this can lead to high - output cardiac failure. Congestive cardiomyopathy, ischemic heart disease, and myocarditis are more commonly associated with low - output cardiac failure as they mainly affect the heart's ability to contract effectively (systolic dysfunction in most cases of these conditions), reducing the cardiac output rather than increasing it.

Answer:

Anemia
