Question

The magnitude of ischemia caused by a coronary lesion generally is proportional to:

A) Age
B) Blood pressure
C) Exercise intensity
D) Resting heart rate

Answer 1

The magnitude of ischemia caused by a coronary lesion is generally proportional to exercise intensity.

Step-by-step explanation:

The magnitude of ischemia caused by a coronary lesion is generally proportional to exercise intensity. When you exercise, your heart pumps harder to deliver oxygenated blood to the muscles. If there is a coronary lesion, the constricted artery will limit blood flow, causing ischemia. The more intense the exercise, the greater the demand for oxygen, and therefore, the greater the magnitude of ischemia.
