The coronary arteries are the vessels that supply the heart muscle with blood rich in oxygen. They are called the coronary arteries because they encircle the heart in the manner of a crown. The word “coronary” comes from the Latin corona and Greek koron meaning crown. Like other arteries, the coronaries may be subject to arteriosclerosis (hardening of the arteries). There are a number of coronary arteries. Those most often bypassed today include the right coronary artery, the posterior descending coronary artery, the left main coronary artery, the left anterior descending coronary artery and the left circumflex coronary artery. Plaques obstructing the coronary arteries may also be treated by balloon angioplasty, stents, and other techniques. However we now have the ability to safely reduce plaque (atherosclerosis) with a formula developed in Europe which includes intravenous phosphytidal choline (known as Plaquex in Europe) and soften hardened walls of arteries (arteriosclerosis) with intravenous EDTA chelation therapy. Surgery should now be considered an absolute last resort for cases so advanced there is no other solution, however it is not so considered by surgeons and hospitals – which may have something to do with how lucrative it is for doctors and hospitals to do these procedures. This condition prevales despite a mortality rate of up to 5% for bypass surgery.
