Improved definition of the structure of plasma lipoproteins will lead to an understanding of factors important in normal lipoprotein metabolism, tissue and cellular uptake and regulation of lipid metabolism and the pathogenesis of atherosclerosis. Pathophysiology of coronary artery disease atherosclerosis is a type of arteriosclerosis caused by a build-up of plaque in the inner lining of an artery (arteriosclerosis is a general term for thickening or hardening of the arteries) (porth 2005) plaque is made up of deposits of fatty substances, cholesterol, cellular waste products, calcium.

Atherosclerosis is a chronic disease of the arterial wall whose underlying pathogenesis involves an imbalanced lipid metabolism and a maladaptive immune response involving chronic inflammation of the arterial wall [1. In atherosclerosis, which is the most common form of arteriosclerosis, small patchy areas called atheromas form that can block the vessel lumen and cause arterial spasms all arteries are susceptible to atherosclerosis, but the aorta, coronary and carotid arteries are affected most. Atherosclerosis may also cause sudden death without preceding stable or unstable angina pectoris atherosclerotic involvement of the arterial wall can lead to aneurysms and arterial dissection, which can manifest as pain, a pulsatile mass, absent pulses, or sudden death.
