Like any other muscle in the body, the heart depends on a steady supply of oxygen rich blood. The arteries that carry this blood supply to the heart muscle are called coronary arteries. Sometimes these blood vessels can narrow or become block by deposits of fat, cholesterol and other substances collectively know as plaque. Over time plaque deposits can narrow the vessel so much that normal blood flow is restricted. In some cases the coronary artery becomes so narrow that the heart muscle itself is in danger. Coronary bypass surgery attempts to correct this serious problem. This cardiovascular disease is one of the leading causes of mortality in the USA. More importantly, Coronary Heart Disease (CDH) kills around 370,000 people annually. On Figure 1. The map provided below is about the death rates due to heart disease in the USA between 2008 and 2010. It is shown that the death rates due to heart disease were highest in the South and lowest in the West. Figure 1.
