Which condition is described as chest pain due to transient myocardial ischemia without infarction?

• A. Myocardial Ischemia
• B. Aneurysm
• C. Myocardial Infarction
• D. Angina Pectoris

Answer: (D)

Chest pain caused by a temporary drop in blood flow to the heart muscle, without lasting injury, is angina pectoris. This reflects reversible myocardial ischemia—the heart muscle is briefly deprived of oxygen, leading to chest discomfort that typically resolves with rest or nitroglycerin as blood flow improves. Unlike myocardial infarction, angina does not involve permanent heart muscle cell death, so there are no lasting structural damage or biomarker elevations. Aneurysm is a structural dilation of a vessel or heart wall and does not describe transient ischemia with chest pain. So the description fits angina pectoris, the term used for chest pain arising from reversible ischemia.
