What is the medical term for episodes of chest pain due to insufficient oxygenated blood supply to the heart?

• A. Myocardial Infarction
• B. Angina Pectoris
• C. Coronary Artery Disease
• D. Pulmonary Embolism

Answer: (B)

The medical term for episodes of chest pain that occur due to insufficient oxygenated blood supply to the heart is known as Angina Pectoris. Angina is typically caused by reduced blood flow to the heart muscle, often due to coronary artery narrowing or blockage. It manifests as discomfort or pain in the chest, which can also radiate to the shoulders, neck, arms, or back. These episodes can be triggered by physical activity or emotional stress when the heart demands more oxygen than it can receive.

In contrast, a myocardial infarction refers to a heart attack, which occurs when blood flow to a part of the heart is completely obstructed, leading to significant damage to the heart muscle. Coronary artery disease is a broader term that encompasses the buildup of plaques in the coronary arteries, leading to both angina and potential heart attacks. Pulmonary embolism, although it can cause chest pain, results from a blockage in the lungs and is not related to the insufficient supply of oxygenated blood to the heart itself.
