A wire is inserted into your groin and then into your heart where an iodide based contrast agent will be administered and X-Rays taken of your coronary arteries. However, after a dose of Valium, one does not fear anything. The more cholesterol a person has bound to HDLs the lower the risk of coronary heart disease. LDLs are believed to promote coronary heart disease by first penetrating the coronary artery wall, where they are broken down enzymatically to cholesterol, cholesterol esters and protein. The cholesterol and cholesterol esters are then oxidized in the artery wall, becoming major parts of atherosclerosic plaque.
Atherosclerosis is essentially a chronic form of inflamation.
If the receptor is then activated, by a process known as phosphorylation, it can transmit a message into the cell. That message might stoke inflamation, for example. It was determined that the best course of action would be to place a stent in the blocked coronary artery. The stent would force the blockage open and ensure that the artery would remain open. The following figure illustrates the same artery without a blockage.
