What Are The Three Major 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
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
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
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
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
Cardiac Cath: Still, today, the most reliable means of demonstrating "blocked" arteries is cardiac catheterization otherwise known as angiography. Ct scan angiography when done in good hands and experienced centers, is also a reliable test, and if negative, makes it very unlikely that the person has significant disease. ...Read more
Heart disease: The coronary arteries arise in the aortic root and branch across the heart with branches extending around and into the myocardium. ...Read more
Blood flow: The coronary arteris originate with an os or opening which directs blood from the aorta into the coronaries and then into capillaries to provide the heart muscle with blood. ...Read more
