  Coronary Artery Bypass Grafting
The blockages or narrowings of the coronary arteries is known as coronary artery disease and is secondary to a disease process known as arteriosclerosis, commonly referred to as "hardening of the arteries".
In performing a coronary artery bypass, the surgeon utilizes a piece of vein from the patient's leg or an artery located on the inside of the chest to create an alternative pathway for the oxygen-rich blood to enter the narrowed or blocked artery so that this blood can reach the heart muscle.
Traditionally, coronary artery bypass grafting operations are done using the heart-lung machine, which is commonly referred to as the "pump".

  Coronary artery bypass surgery - Wikipedia, the free encyclopedia
Early in a coronary artery bypass surgery during vein harvesting from the legs (left of image) and the establishment of bypass (placement of the aortic cannula) (bottom of image).
Coronary artery bypass surgery, also coronary artery bypass graft surgery and heart bypass (colloquial), is a surgical procedure performed on patients with coronary artery disease (see atherosclerosis) for the relief of angina and possible improved heart muscle function.
Veins or arteries from elsewhere in the patient's body are grafted from the aorta to the coronary arteries, bypassing coronary artery narrowings caused by atherosclerosis and improve the blood supply to the myocardium (heart muscle).

In particular, coronary artery bypass surgery during the same hospital admission as the angioplasty, and myocardial infarction (heart attack) during or after the angioplasty in the same hospital admission will be reported as soon as possible, probably in 1999 (using 1997 data).
Also, coronary artery bypass graft surgery may be related to myocardial infarctions in that the tendency not to perform bypass surgery when it is necessary could lead to a myocardial infarction.

 MARKETING AN OPERATION:CORONARY ARTERY BYPASS SURGERY
In fact, for years before the advent of the coronary-bypass operation surgeons had performed similar operations on the larger arteries in the legs, using long, thin, artificial pipelines to carry blood from a point in front of to a point beyond an obstruction in the artery.
In 1977 the Veterans Administration reported a study showing that bypass surgery caused no decrease in average annual mortality among patients with ordinary angina unless they happened to be suffering from an obstruction of the left main coronary artery, a particularly severe form of heart disease.
The charges vary greatly, depending on the surgeon, the number of bypass grafts (generally each graft beyond the first one costs an additional $400 to $600), the hospital, and on the location (the difference may be as much as 100% from one part of the country to another).

Coronary artery bypass surgery, also coronary artery bypass graft surgery, and colloquially heart bypass or bypass surgery is a surgical procedure performed to relieve angina and reduce the risk of death from coronary artery disease.
Arteries and /or veins from elsewhere in the patient's body are grafted from the aorta to the coronary arteries to bypass atherosclerotic narrowings and improve the blood supply to the coronary circulation supplying the myocardium (heart muscle).
A greater number of bypasses does not imply a person is "sicker," nor does a lesser number imply a person is "healthier." A person with a large amount of coronary artery disease (CAD) may receive fewer bypass grafts due to the lack of suitable "target" vessels.

 Coronary Artery Bypass Graft Surgery (Heart Bypass Surgery, CABG) Information on MedicineNet.com
Coronary artery disease (CAD) occurs when atherosclerotic plaque (hardening of the arteries) builds up in the wall of the arteries that supply the heart.
When coronary arteries narrow more than 50 to 70%, the blood supply beyond the plaque becomes inadequate to meet the increased oxygen demand during exercise.
When arteries are narrowed in excess of 90 to 99%, patients often have accelerated angina or angina at rest (unstable angina).

Angiograms are used to evaluate the condition of the coronary arteries and nourishment of the heart muscle.
When a blockage (stenosis) within an artery prevents that vessel from delivering an adequate supply of blood to the tissues it serves, the body can sometimes compensate by developing and/or opening small specialised vessels to transfer blood form "healthier" arteries to the deprived tissues that are downstream of the blockage.
The coronary arteries that supply blood to the heart are especially vulnerable.

ABSTRACT : The dynamic responses of a coronary artery and an internal mammary artery (IMA) graft to pharmacological intervention were examined by arteriography in 5 patients with variant angina who had undergone coronary artery bypass grafting with an in situ IMA to the left anterior descending coronary artery.
These results indicate that internal thoracic artery grafts have flow adaptability responding to the flow demand of the recipient coronary artery and that the string sign of internal thoracic artery grafts is mainly an outcome of its physiologic characteristics.
In adult patients with bypass grafting for atherosclerotic coronary artery disease, IMA grafts have been reported to have long-term patency; however, results are conflicting on whether the graft is sufficient to meet increased myocardial oxygen demand during exercise.
