Which of the following conditions is described by the sudden blockage of a coronary artery leading to tissue death?

Angina Pectoris
Aortic Aneurysm
Congestive Heart Failure
Myocardial Infarction

The correct answer is: Angina Pectoris

The correct answer is D. Myocardial Infarction. Myocardial infarction, also known as a heart attack, occurs when there is a sudden blockage in one of the coronary arteries that supply blood to the heart muscle. This blockage leads to a lack of oxygen-rich blood reaching the heart tissue, causing tissue death. A. Angina Pectoris is characterized by chest pain or discomfort due to reduced blood flow to the heart muscle, usually caused by coronary artery disease. It is not associated with tissue death like a myocardial infarction. B. Aortic Aneurysm is a condition where there is a bulge in the wall of the aorta, the body's main artery. It is not directly related to a sudden blockage in a coronary artery. C. Congestive Heart Failure is a chronic condition where the heart is unable to pump blood effectively. While it can be caused by a heart attack (myocardial infarction), it is not the sudden blockage itself that characterizes congestive heart failure.
