What can result from insufficient blood supply to the heart?

When there is insufficient blood supply to the heart, it can lead to both angina pectoris and myocardial infarction.

Angina pectoris occurs when the heart muscle doesn't get enough oxygen-rich blood, usually due to narrowed or blocked coronary arteries. This condition results in chest pain or discomfort, often triggered by physical exertion or emotional stress. It serves as a warning sign that the heart is not receiving adequate blood flow, suggesting that there may be underlying heart disease.

Myocardial infarction, often referred to as a heart attack, happens when a part of the heart muscle is damaged or dies because of prolonged lack of blood supply. This usually occurs when a coronary artery is completely blocked, preventing blood from reaching a portion of the heart. This condition is often more severe than angina pectoris and requires immediate medical attention.

Both conditions stem from issues related to insufficient blood supply to the heart, making the inclusion of both angina pectoris and myocardial infarction as potential outcomes accurate. Therefore, the correct answer includes both of these critical cardiovascular events as a result of insufficient blood supply to the heart.
