What is coronary atherosclerosis of native coronary artery?
Coronary Atherosclerosis: is a condition in which the arteries of the heart become clogged with fatty plaque build-up that restricts the amount of blood flow through the arteries while simultaneously causing hardening of the arterial walls. Native Coronary Artery: is an organ for which a transplant or bypass has been implanted
How does a coronary heart attack occur?
A heart attack or myocardial infarction occurs in areas of the heart that lack blood flow. Blood, carried by coronary arteries around the heart, would normally provide oxygen & nutrition while taking away carbon dioxide. Without oxygen, the area would become necrotic & myocardial cells would die. Angina, or chest pain, is usually a precursor to a heart attack. Patients that experience chest pain should see their health care provider to possibly undergo a stress test. A cardiac catheterization may be needed to determine which coronary vessel(s), also called coronary arteries, is occluded or blocked. Occlusion occurs due to years of atherosclerosis, or buildup of lipids from diet & hereditary factors. If the left main coronary artery is blocked, usually a CABG (coronary artery bypass graft) is needed. If other arteries are involved, a coronary stent might be another option. If minimal occlusion is found during catheterization, a patient may just require an antiplatelet agent, such as aspirin or clopidogrel.
Will the compression of CPR causes the leakage of the blood when a person's coronary artery is burst and experiences heart attack?
You would not know if a persons Coronary Artery has burst in the field. That is something that would require a surgeon (or more likely autopsy) to discover. Coronary Arteries very rarely burst, though they do become blocked. The most common place for vessels to burst is in the brain. If a person suffers a heart attack, perform CPR. Don't worry about the cause, nor should you worry about leaking blood from internal injuries.
What can happen when blood supply to the heart is blocked-?
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
When valves in the heart or blood vessels fail to function?
When there is a problem in blood flow there is the risk of cellular death. In the heart, this complication can be fatal, however, this may not be as problematic in the rest of the body depending on the size or the artery blocked. When there is a problem in the blood flow of the heart, which is supplied by the coronary arteries, the myocytes of the heart can die. If a smaller artery in heart is blocked, this cell death can even go unnoticed, but will lead to the fibrosis of the heart tissue, not only making it less compliant, but potentially causing problems in the way the heart functions such as re-entry, which can lead to arrhythmias. In the rest of the body, the blockage of a major vessel can be a big problem. However, if a small blood vessel is blocked the body may have collateral circuits to continue blood supply to tissue. An example of this is the internal thoracic arterty supplying posterior intercostal muscles through the anterior intercostal arteries if the posterior intercostal arteries become blocked. So, blockage of blood vessels can lead to some big problems, especially in the heart; however, the body does have ways of supplying blood to tissues if they become blocked.
What blocked arteries can be bypassed by using veins in the leg?
They are called left internal mammary arteries (LIMAs).

What is the correlation between coronary heart disease and smoking?
Smoking is a major cause of atherosclerosis " a buildup of fatty substances in the arteries. Atherosclerosis occurs when the normal lining of the arteries deteriorates, the walls of the arteries thicken and deposits of fat and plaque block the flow of blood through the arteries. In coronary artery disease, the arteries that supply blood to the heart become severely narrowed, decreasing the supply of oxygen-rich blood to the heart, especially during times of increased activity. Extra strain on the heart may result in chest pain and other symptoms. When one or more of the coronary arteries are completely blocked, a heart attack may occur.
How good are statins?
When there are high levels of cholesterol in the blood stream, it can collect within the blood vessels causing them to become narrowed or blocked. This is bad enough when in a peripheral artery, but can be lethal if it occurs in the coronary arteries. These are the vessels that provide the blood supply to heart muscle. If they become narrowed, blood struggles to get to the tissue meaning the oxygen level in the tissue becomes depleted and it is at risk of dying. If the coronary arteries become completely blocked the chance of suffering from a heart attack is very high. By helping the blood cholesterol to drop the arteries are not only more protected from becoming more blocked, but may in fact force the cells to take their cholesterol from existing supplies and reduce any existing blockages; this can help reduce the damage that has already occurred.
What is nitrostat tablets?
Nitroglycerin is prescribed to prevent and treat angina pectoris (suffocating chest pain). This condition occurs when the coronary arteries become constricted and are not able to carry sufficient oxygen to the heart muscle Thank You FactPalooza.Com
What is arteriosclerotic disease?
Arteriosclerotic cerebrovascular disease is a condition of reduced blood flow to the brain. The cause of this condition is hardening of the arteries caused by buildup of plaque.
Coronary Heart Disease – A Silent Killer of Men and Women?
Coronary heart disease, also known as coronary artery disease, is a disease of the heart that forms when the veins that feed blood and oxygen to the heart become clogged. This disease affects millions of Americans, and kills over 500,000 people in the United States alone each year. However, coronary heart disease is not just a problem that Americans face. The disease is becoming more common in Europe and other Westernized countries. Heart related diseases kill more people around the world than any other disease or causes. Many are not aware that they are suffering from coronary heart disease. The disease slowly progresses. It is possible to see the beginning signs of coronary artery disease in a child of 10 years old or younger. The heart is a muscle and needs its own supply of enriching blood, just like every other muscle and organ in the body. The heart pumps this supply of blood through the hearts chambers. The coronary artery is the main arteries of the heart and has the job of bringing the most oxygen rich blood to the heart. There are other smaller arteries that feed the heart as well. Healthy coronary arteries have very smooth and flexible walls. The walls are strong, but can become easily irritated. Substances that irritate the arteries are calcium, cholesterol, fats and cell debris. When these substances pass through the arteries in excessive amounts, small amounts will stick to the artery walls. This causes the artery walls to slowly harden and starts the onset of coronary heart disease. Over the years, the artery will become narrower due to the buildup of these substances. Eventually the artery will become clogged. The buildup that occurs inside of the coronary artery walls is called atherosclerosis. This is when the fat, debris, cholesterol and calcium turns into a hardened plaque like substance. These plaque deposits build up and continuously become thicker. Symptoms of closing arteries are chest pressure and heart pain, which is referred to as angina. At this stage, the person affected has coronary heart disease. When the blood supply to the heart is completely blocked, the result is a heart attack. Heart bypass surgery is a common way that those with coronary artery disease remove plaque buildup in the arteries. Double, Triple and Quadruple bypass surgery is for those who have arteries in various chambers of the heart blocked. These surgeries are very risky. The best way to avoid getting coronary artery disease is to prevent the disease altogether by eating a healthy and balanced diet and establishing a regular exercise routine.

How is bypass heart surgery done?
Heart bypass surgery, also known as coronary artery bypass surgery, aims to replace damaged arteries in the heart. A surgeon uses blood vessels from another area of the body to repair the damaged arteries. This surgery is used when the coronary arteries become blocked or damaged. The coronary arteries supply the heart's muscles with oxygenated blood. If they are blocked or the flow of blood is restricted, the heart can't function properly. This can lead to heart failure
What system does a stroke affect?
By definition a stroke affects the brain by blocking small arteries that carry blood to the cells and deliver nutrients and oxygen. These become blocked and the cells that the artery is leading to, die. A similar thing happens when arteries to the heart muscle cells that are blocked causing a heart attack.
