3 Main Coronary Arteries
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
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
I m 50 years i have ectasia generalized of coronary arteries excluding main coronary artery plz medical management of disease?
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 part of the heart would receive less blood if the were a blockage in the left main coronary artery?
Left main: Most of the blood to the left ventricle passes thru the left main. That is why it is such a serious lesion. ...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?
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
Arteries : Arteries provide oxygenated blood to the organ or part of the body the go. Coronaries provide blood to the heart. They originate from the ascending aorta right after its origin from the left ventricle. ...Read more
Carry blood: The coronary afteries are located just above the aortic valve. Blood flows through those arteries and suppies oxygen to the heart muscle. A number of factors can cause the arteries to dilate (become wider) so that the flow of blood can increase if needed such as when you exercise. ...Read more
Heart arteries : The coronaries arteries branch off the aorta and run on top of the heart muscle, they provide blood, nutrients and oxygen to the heart muscle for it to keep pumping. When those arteries are blocked the heart muscle can die in a process called heart attack causing the patient to die or causing permanent muscle damage and heart failure. ...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
blood to heart: The coronary arteries supply blood to the heart muscle itself. There are usually 3 — the left anterior descending, circumflex, and right coronary. Closure or blockage of one of these main arteries, or a branch vessel, from cholesterol or a clot, causes a heart attack or angina (chest pain). ...Read more
Four major ones.: There are four major coronary arteries, the left main (lm)' the left anterior descending (lad), the circumflex (lcx), and the right (rca). They branch into many smaller arteries. The lm is considered the most important because it is usually the largest. The LAD is usually the next most important. ...Read more
