In familial hypercholesterolemia, a mutation in the LDLR, PCSK9, or APOB is usually the reason for this and these mutations result in high LDL cholesterol. [8] In combined hyperlipidemia, there is an overproduction of apoB-100 in the liver. [9] This causes high amounts of LDL and VLDL molecules to form. [9]
LDL-C represents how much cholesterol is being transported by all LDL particles, which is either a smaller concentration of large particles or a high concentration of small particles. LDL-C itself can be estimated by subtraction (Friedewald's method) [61] or directly measured; see the section #Testing above to see how it's measured. [62]
Hypercholesterolemia, also called high cholesterol, is the presence of high levels of cholesterol in the blood. [1] It is a form of hyperlipidemia (high levels of lipids in the blood), hyperlipoproteinemia (high levels of lipoproteins in the blood), and dyslipidemia (any abnormalities of lipid and lipoprotein levels in the blood).
Hyperlipidemia is abnormally high levels of any or all lipids (e.g. fats, triglycerides, cholesterol, phospholipids) or lipoproteins in the blood. [2] The term hyperlipidemia refers to the laboratory finding itself and is also used as an umbrella term covering any of various acquired or genetic disorders that result in that finding. [3]
Level of the good cholesterol HDL is also increased. Fibrates may decrease LDL, though generally to a lesser degree than statins. Similar to statins, the risk of muscle damage exists. Nicotinic acid, like fibrates, is also well suited for lowering triglycerides by 20–50%. It may also lower LDL by 5–25% and increase HDL by 15–35%.
Very-low-density lipoprotein (VLDL), density relative to extracellular water, is a type of lipoprotein made by the liver. [1] VLDL is one of the five major groups of lipoproteins (chylomicrons, VLDL, intermediate-density lipoprotein, low-density lipoprotein, high-density lipoprotein) that enable fats and cholesterol to move within the water-based solution of the bloodstream.
A lipid profile or lipid panel is a panel of blood tests used to find abnormalities in blood lipid ( such as cholesterol and triglycerides) concentrations. [not verified in body] The results of this test can identify certain genetic diseases and can determine approximate risks for cardiovascular disease, certain forms of pancreatitis, and other diseases.
High cholesterol levels normally do not cause any symptoms. Yellow deposits of cholesterol-rich fat may be seen in various places on the body such as around the eyelids (known as xanthelasma palpebrarum), the outer margin of the iris (known as arcus senilis corneae), and in the tendons of the hands, elbows, knees, and feet, particularly the Achilles tendon (known as a tendon xanthoma).
