What Is The Function Of Coronary Arteries And Veins
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
Coronary: Coronary arteries supply oxygenated blood to the heart while the veins drain deoxygenated blood away from the heart. ...Read more
Yes: Yes, the coronaryveins are thin walled vessels like all veins. The arteries are thicker, muscular walled structures as the coronary arteries actively dilate and contract in response to cardiac demands and various signals. In many instances, the coronary venous structures travel right next to the arteries. ...Read more
ARBs and Nitro work?: Do ARB'S and Nitro work the same way? (Relax vessels) If so; will ARB'S relax coronary arteries? ANS: No ARBS work by blocking high blood levels of angiotensin II. Nitro works directly on arterial muscles. But both may "relax" blood vessels. ARBS by AII receptor occupation and nitro directly. ...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
My CAG report shows that I have Mild Coronary Artery Disease, Borderline LAD with Mild LCX and RCA disease. Good LV function. Do I have heart problem.
An artery problem: You now know you have a tendency for artery disease, fortunately it is not causing problems yet. I would undertake aggressive lifestyle and medical measures to slow down this process! Exercise, weight control, aspirin, lipid therapy, control blood sugar, no smoking, beta blockers, ace inhibitors. ...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
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
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
Coronary artery is the name given to the blood vessels that supply the myocardium.
The word coronary was coined by the first anatomists that noticed that if you remove all muscle from the heart the remaining vessels resemble the shape of a corona or crown. Hence the name coronary. ...Read more
