Question

myocardial infarction affects which of the following blood vessels of th
aorta
pulmonary
vena cava
coronary

Explanation:

Myocardial infarction, commonly known as a heart attack, occurs when there is a blockage in the coronary arteries. These arteries supply blood to the heart muscle. A blockage in the coronary arteries deprives the heart muscle of oxygen - rich blood, leading to myocardial infarction. The aorta is the main artery that carries blood from the heart to the rest of the body. The pulmonary artery carries de - oxygenated blood from the heart to the lungs. The vena cava is a large vein that carries de - oxygenated blood from the body back to the heart. None of these (aorta, pulmonary, vena cava) are directly related to the blood supply of the heart muscle in the context of myocardial infarction.

Answer:

Coronary
