Are there differences in appearance between coronary arteries and veins?

Are there differences in appearance between coronary arteries and veins?

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

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

What do the coronary arteries and veins do?

What do the coronary arteries and veins do?

Coronary A/V: The coronary arteries take blood from the aorta to the heart and the coronary veins drain the blood from the heart. The heart is a muscle, therefore, it requires blood to function. When a coronary artery becomes blocked then a heart attack can occur. ...Read more

What is the function of coronary arteries and veins?

What is the function of coronary arteries and veins?

Arteries/veins: Every organ needs a supply line (artery) and discharge (vein). Think of your faucet and drain. The coronary arteries supply the heart muscle with oxygen and energy, the veins carry off the metabolic waste. ...Read more

What are the functions of coronary arteries and veins?

Heart blood flow: Coronary arteries bring oxygenated blood to the heart. Coronary veins returned that same blood to the venous circulation. Both types of vessels sit on the surface of the heart. ...Read more

Do ARB'S and Nitro work the same way? (Relax vessels) If so; will ARB'S relax coronary arteries?

Do ARB'S and Nitro work the same way? (Relax vessels) If so; will ARB'S relax coronary arteries?

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

Are there gender differences in regards to levels of coronary artery disease?

Are there gender differences in regards to levels of coronary artery disease?

Yes: Men have higher rates of CAD and they tend to suffer at an earlier age. This is part of the reason the life expectancy of men is shorter than women. ...Read more

Are there racial differences in regards to levels of coronary artery disease?

Are there racial differences in regards to levels of coronary artery disease?

Always: Many stuides show differences among racial lines; my personal opinion is that these really demonstrate differences in socioeconomic levels. I feel it is much more dependent upon income levels and the types of foods and lifestyle a person leads. Lower socioeconomic groups tend to eat foods that are less healthy and engage in alcohol and tobacco use as well as engaging in less exercise. ...Read more

What is the difference between off-pump and on-pump coronary artery bypass?

What is the difference between off-pump and on-pump coronary artery bypass?

Controversial: On pump - not moving heart better grafting condition; postop graft latency may be better; more postoperative neurocognitive dysfunction; more bleeding and transfusions. Off- moving heart with maybe less postop patency of the graf (skill dependent); less blood loss and transfusions; less neuro problems; less renal problems. Mortality the same. Depend on skill, comfort of surgeon and hospital. ...Read more

Please help! What is the difference (including advantage and disadvantage) of off-pump and on-pump coronary artery bypass?

Very complicated.: Even after a lot fo studies, it is controversial. It depends on a lot of things. Some people have aortas that cannot be clamped or manipulated due to calcium. Off-pump bypass may be their only option. Other patients can't have off pump bypass. For most people, the decision should involve the patient, the surgeon, and other trusted physicians. ...Read more

Difference between coronary artery and just muscle spasm in chest?

Difference between coronary artery and just muscle spasm in chest?

Huge difference: Technically the heart is also a muscle but pain from the heart due to coronary artery disease is an extremely serious and potentially life threatening condition. Muscle spasms from the chest wall muscles are not common and are usually in response to some type of chest wall injury. If you are having pain in your chestthe first thing to do is see your doctor immediately or go to an er to check it. ...Read more

What is the difference between angina, coronary artery disease, and heart disease?

Symptom, Disease: Angina and angina equivalents are symptoms of cad: coronary artery disease - which is often pooled with other heart aliments and described as heart disease. Heart disease could potentially encompass other conditions such as congestive heart failure, chf, atrial fibrillation or flutter, af, kinds of cardiomyopathy, bundle branch block, and valve disorders and potentially more. ...Read more

Is there a difference between coronary artery disease and congestive heart failure?

Is there a difference between coronary artery disease and congestive heart failure?

Yes: Coronary artery disease means the arteries of the heart have partial or complete blockage. Congestive heart failure means the heart musle is weak and not pumping blood well enough and fluid back up into the lungs. Often patients with congestive heart failure have coronary artery disease, but not always. ...Read more

Can you tell me the difference between congestive heart failure and coronary artery disease?

Can you tell me the difference between congestive heart failure and coronary artery disease?

Disease vs symptom: Coronary artery disease is cholesterol build up in the coronary arteries. CHF is a symptom complex of shortness of breath. Unable to lay flat. Waking up short of breath and decrease exercize tolerence. It usually occurs when blood backs up in the lungs as a result of the heart not working efficiently. CHF is not a diagnosis as there are many causes and a source should be found. ...Read more

Please help! What is the difference between coronary artery disease & congestive heart failure?

Please help! What is the difference between coronary artery disease & congestive heart failure?

Blocked arteries vs.: Coronary artery disease typically refers to atherosclerosis of the coronary arteries which supply blood to the heart muscle. Atherosclerosis blocks the coronary arteries. Congestive heart failure is heart disease that restricts the heart's ability to deliver oxygen to the body, typically with increased filling pressure of the heart (causing fluid backup, or congestion.). ...Read more

Different problems: Coronary artery disease is a narrowing of the small blood vessels that supply blood and oxygen to the heart. (http://1.Usa. Gov/lrisvf) congestive heart failure is a condition in which the heart can no longer pump enough blood to the rest of the body. (http://1.Usa. Gov/lrirha). ...Read more

There: what is the difference between congestive heart failure and coronary artery disease in a diabetic?

What is the difference between coronary artery disease and ischemic heart disease?

They are related: But the technical difference would be related to whether the blockages in the arteries (coronary disease) are causing the heart to get less blood flow and oxygen than it needs to function properly (ischemic disease). You can have coronary disease without ischemia, but other than unusual conditions, it's less likely to have ischemia without coronary disease. ...Read more

My friend has blocked coronary arteries. What are the possible causes?

My friend has blocked coronary arteries. What are the possible causes?

Atherosclerosis: Far and away the most common reason for this is build up of plaque in the arteries, called atherosclerosis. This is caused by a combination of high blood pressure, smoking, high cholesterol, and aging. Reducing these risk factors (we can't do anything about age except exercise!) helps prevent this from happening. ...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. ...Read more
