Question

Quizplus · Accepted Answer

Angina pectoris refers to a temporary decrease in the oxygen supply to the heart muscles, causing chest pain or discomfort. It is caused by the narrowing of the coronary arteries that supply blood to the heart. Hardening of the arteries (arteriosclerosis) may contribute to the development of angina, but it is not the same as angina. Option C (death of cardiac cells with no symptoms) and option D (spasm of the heart causes dizziness and nausea) do not accurately define angina pectoris.
