Atherosclerosis Atherosclerosis is a complex disease characterized by thickening of the inner layer of the artery walls due to the accumulation of lipids. It is a progressive disease that gradually blocks the blood vessels and limits blood flow. Info: Inflammation is the key process to include the steps of blood flow restriction to the certain areas of affected vessels. Coronary arteries supplying blood to the heart are the most commonly affected because they have to work the most. The development of atherosclerosis is associated with high levels of low-density lipoprotein cholesterol (LDL) and low levels of high-density lipoprotein cholesterol (HDL). Plasma HDL is considered considerably protective against CHD. Lipid Profile It is a panel of blood tests used to check cholesterol and triglyceride levels. The results of this test can help determine genetic risks for cardiovascular disease and other diseases. The lipid profile typically includes: Low-density lipoprotein (LDL) High-density lipoprotein (HDL) Triglycerides Total cholesterol Doctors use these values to calculate and assess other cholesterol-related numbers. Very-low-density lipoprotein (VLDL) cholesterol and HDL cholesterol ratio. Typically, the lab measures these quantities: Total cholesterol HDL (high-density lipoprotein) Triglycerides From these measures, LDL can be calculated: LDL = [Total cholesterol] - [HDL] - [Triglycerides] VLDL can be defined as the total cholesterol that is neither HDL nor LDL. With that definition, VLDL is calculated as: VLDL = [Triglycerides]/5
