Question

Quizplus · Accepted Answer

The increased heart rate and stronger cardiac contraction during a stress test indicate a demand for more oxygen and nutrients to the heart muscles. To meet this demand, the coronary arteries dilate (widen) to increase blood flow and deliver more oxygen and nutrients to the heart muscle. Constriction of the coronary arteries would result in reduced blood flow and potentially cause chest pain or other symptoms of ischemia. Vasospasm, which is a sudden constriction of the coronary artery, can cause chest pain and lead to a heart attack, but this is not indicated in the scenario provided.
