Coronary artery disease, also called coronary heart disease, is a heart disease. ("Coronary" means "the blood vessels of the heart".) Coronary heart disease causes plaque to build up inside the coronary arteries. This causes the coronary arteries to become narrower. An artery is a blood vessel - a tube that carries blood. After the heart supplies blood that is full of oxygen and nutrients, the arteries carry the blood to different parts of the body. The coronary arteries are very important: they supply blood to the heart muscle. So when the coronary arteries become narrower, less blood gets to the heart muscle.

Questions and Answers
Q: What is coronary artery disease?
A: Coronary artery disease is a heart disease that causes plaque to build up inside the coronary arteries, leading to their narrowing and reduced blood flow to the heart muscle.
Q: What do the coronary arteries do?
A: The coronary arteries supply blood to the heart muscle.
Q: What happens when the coronary arteries become narrower?
A: When the coronary arteries become narrower due to plaque buildup, less blood gets to the heart muscle, which can lead to chest pain, heart attack, or other complications.
Q: What is the meaning of "coronary" in relation to the heart?
A: "Coronary" means the blood vessels of the heart.
Q: What are arteries?
A: Arteries are blood vessels that carry blood, which is full of oxygen and nutrients, from the heart to different parts of the body.
Q: How does plaque buildup affect the coronary arteries?
A: Plaque buildup inside the coronary arteries causes them to become narrower, which reduces the flow of blood to the heart muscle.
Q: Why are the coronary arteries important?
A: The coronary arteries are important because they supply blood to the heart muscle, enabling it to function properly.
