Plaque In The Aorta
In atherosclerosis, plaque builds up in the arteries occluding the lumen.How would this affect bp?
Is the artery wall thickening that occurs in moyamoya disease the same as the the thickening in atherosclerosis?
NO: In Moyamoya disease the inner layer of the inner layer of the carotid artery overgrows and fills the artery, eventually closing it off. But this is not like atherosclerosis where the walls of arteries are damaged, leading to deposition of cholesterol and white blood cells. Both can cause strokes, but Moyamoya is seen in younger adults or even children! An angiogram shows the difference. ...Read more
Yes: They are branches off of the aorta in the upper abdomen. ...Read more
Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?
Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read moreSee 3 more doctor answers
How does the build up of plaque in someone with atherosclerosis cause the hardening of the arteries?
Not the same things: Plaque buildup (atherosclerosis) in the arteries can make them less flexible, but the old term "hardening of the arteries" (arteriosclerosis) is usually attributed to a decrease in flexibility of the vessel wall even without any plaque present. It is more related to the collagen/structure of the vessel wall themselves. The utility of this term is waning as medicine advances. ...Read more
Atherosclerosis: Plaque build up may be progressive and cut off the flow of blood to the receiving organ like the heart, brain, legs etc. Or the plaque can break open sending little pieces down stream or worse the plaque can break open and potentate a blood clot that completely and suddenly blocks the flow of blood - think heart attack or stroke. This is the #1 cause of death in the United States. ...Read moreSee 1 more doctor answer
What is the difference betweens the walls of the veins entering the atria and the walls of the arteries leaving the ventricle?
See below: Lad ("left anterior descending" artery)--affects anterior (front) wall of the left ventricle, and apex (the tip). Circumflex artery--affects the lateral wall of left ventricle, and usually part of the posterior (back). Right coronary artery--affects inferior (bottom) wall of left ventricle and all of the right ventricle (if occluded proximally enough in its course). ...Read moreSee 1 more doctor answer
Not a sign of plaque: 30% block in your carotid artery will not cause pain in your neck area.It is an indicator that it can compromise the blood flow to the brain if gets worse.One has to control the LDL levels in blood and bring it down with statins and diet.If it it prgresses to 60% or more, than you will need endarterectomy and reduce the chances of it leading to stroke. ...Read moreSee 1 more doctor answer
Diseased Arteries: The lining of your arteries can be affected by high level of blood fats like Cholesterol, high BP and smoking. These conditions can lead to development of Atherosclerosis causing narrowing of the arteries due to fat deposits. Hardening of arteries is a different disease, mostly occurring in elderly folks and is part of the aging process. Hardened arteries are not narrowed most of the time. ...Read more
Atherosclerosis: Narrowing or 'hardening of the arteries' seems like the body's way of planned obsolescence--or complete wearing out. Over time our arteries become more narrow and certain conditions speed up the process: smoking, diabetes (and overweight/metabolic syndrome), hi blood pressure, and hi cholesterol. Exercise can slow down the process. Plaque build up in arteries leads to heart attack and strokes. ...Read moreSee 1 more doctor answer
