Which of the following physiologic changes would increase cardiac work but not enhance cardiac output?

Question

Quizplus · Accepted Answer

Increased afterload refers to an increase in the resistance that the heart must pump against to deliver blood into the circulation. This will increase the workload of the heart, but will not necessarily increase the amount of blood pumped out (cardiac output) by the heart. This can lead to decreased cardiac function and potentially heart failure if the afterload is too high for too long.
