Verified step by step guidance

Understand that angina pectoris is a condition related to the heart, specifically involving the coronary arteries that supply blood to the heart muscle.

Recognize that angina pectoris is not caused by a complete blockage of a coronary artery. A complete blockage would lead to a myocardial infarction (heart attack), not angina.

Note that angina pectoris does not result in permanent damage to the heart muscle. It is a temporary condition that occurs when the heart muscle does not receive enough oxygen-rich blood.

Clarify that angina pectoris is not due to an excess supply of oxygen to the heart muscle. Instead, it is the result of a temporary reduction in blood flow and oxygen supply.

Conclude that the correct statement is that angina pectoris is caused by a temporary reduction in blood flow to the heart muscle, leading to chest pain or discomfort.
