Q #1: A myocardial infarction affects which of the following blood vessels of the heart?
A. Pulmonary
B. Aorta
C. Vena cava
D. Coronary
Answer Explanation
A myocardial infarction (MI), commonly known as a heart attack, occurs when the flow of blood to the heart is blocked. The blockage is usually due to a buildup of fat, cholesterol and other substances in the heart (coronary) arteries. The fatty, cholesterol-containing deposits are called plaques. The process of plaque buildup is called atherosclerosis. Sometimes, a plaque can rupture and form a clot that blocks blood flow. A lack of blood flow can damage or destroy part of the heart muscle.
