Coronary Artery Disease (CAD) (or atherosclerotic heart disease) is
the end result of the accumulation of atheromatous plaques within
the walls of the coronary arteries that supply the myocardium with
oxygen and nutrients. It is sometimes also called Coronary Heart
Disease (CHD) [1]. As the degree of coronary artery disease progresses, there may be near-complete obstruction of the lumen of the coronary artery,
severely restricting the flow of oxygen-carrying blood to the myocardium. Individuals with this degree of coronary artery disease typically have suffered from one or more myocardial infarctions (heart attacks), and may have signs and symptoms of chronic coronary ischemia, including symptoms of angina at rest [1]
