Question: 1 / 400

Fatigue in cardiac patients often stems from what underlying issue?

Increased physical activity

Improved cardiac function

Decreased cardiac output

Fatigue in cardiac patients is often a result of decreased cardiac output. This condition arises when the heart is unable to pump an adequate amount of blood to meet the body's needs, particularly during physical activity or any increased demand. When cardiac output is compromised, organs and muscles may not receive sufficient oxygen and nutrients, leading to feelings of fatigue and weakness.

In contrast, increased physical activity typically enhances conditioning and overall cardiovascular fitness, rather than causing fatigue. Improved cardiac function would also correlate with a better capacity for physical activity and reduced fatigue. A high oxygen supply to tissues is generally associated with better energy levels and reduced feelings of tiredness. Therefore, among the provided options, decreased cardiac output is the most significant contributor to fatigue in cardiac patients.
