What condition is characterized by decreased blood supply to the heart?

Cardiac arrest
Angina pectoris
Anaphylactic shock
Diabetic acidosis

The correct answer is: Angina pectoris

Angina pectoris is characterized by decreased blood supply to the heart, which leads to chest pain or discomfort. This condition occurs when the heart muscle does not receive enough oxygen-rich blood, often due to narrowed coronary arteries—a process typically associated with coronary artery disease. The pain can be triggered by physical activity or emotional stress and usually resolves with rest or medication such as nitroglycerin. In contrast, cardiac arrest refers to the complete cessation of heart function, which is a more severe and acute condition. Anaphylactic shock is a life-threatening allergic reaction that can cause a sudden drop in blood pressure and inadequate blood supply to organs, but it does not specifically pertain to reduced blood supply to the heart. Diabetic acidosis is a metabolic condition resulting from uncontrolled diabetes, leading to increased acid in the body, but it is not related to blood supply issues of the heart.
