Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Depends: If you're diabetic, CABG has better outcomes. If your LEFT MAIN coronary artery has >50% blockage, CABG has better outcomes. Aside from those 2 points, it depends on the skill of the team you have. If they do a lot of angioplasty, that would be preferred. If they don't but their surgical team is first-rate, then that would be preferred. ...Read more

How many main coronary arteries?

1: When referring to the "main" coronary artery, that is usually refers to the left main (lm) coronary artery. This artery divides quickly into the left anterior and left cicumflex artery, both very important and large conduits supplying much of the heart muscle with blood. The right coronary artery usually has its own origin. In some people there is no lm and each artery has its origin off the aorta. ...Read more

Feed heart muscle: In humans usually two main coronary arteries come off the aorta to feed the heart muscle. The right coronary feeds the right side of the heart and some muscular wall between the two sides. The left coronary divides into the left anterior descending artery and the circumflex coronary artery. The arteries bring oxygen and food to heart muscle cells. ...Read more

Picture this: The coronary arteries branch off from the walls of the aorta, and dive into the outer layer of the heart mucle. On the left side, the left main artery branches into the left anterior decending (lad), which runs down the front wall of the heart, and the circumflex, which runs around the lateral wall. On the right, the right coronary artery runs along the bottom wall of the heart. ...Read more
