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

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

Result of Angiography: three vessel coronary artery desease. Preserved LV systolic function.what is best FOR MEAngioplasty or bypass operation?

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

What do you recommend if I had a heart angiogram with 70% blockage in my left main coronary artery.no stint.dr afraid he would block.why?

Bypass surgery: Everything is a balance between risk/benefit. Often with a > 50% left main blockage, a bypass surgery is the safest choice. Medical therapy alone carries a high risk of sudden death due to the severity of the blockage. A stent placement there, though relatively simple — might have a catastrophic outcome if any slight thing went wrong. A stent is indicated if surgery is higher than usual risk. ...Read more

Had a CT A done, this was the results Mild calcification of the left main. Otherwise, normal coronary arteries. What does that mean?

Had a CT A done, this was the results Mild calcification of the left main. Otherwise, normal coronary arteries. What does that mean?

Occult CAD present: There is evidence of coronary atherosclerosis in your arteries atleast in the left main artery and albeit mild. Over time cholesterol hardens and that is what CT scan picks up. So at your young age if there is early atherosclerosis, you should have your fasting lipid panel be checked and then modify your lifestyle to mitigate progression of cholesterol build in your arteries. ...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

On the right, the right coronary artery runs along the bottom wall of the heart. ...Read more
