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]
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]
[104] [105] For men ages 45 to 65 and women ages 55 to 65, a cholesterol test should occur every 1–2 years, and for seniors over age 65, an annual test should be performed. [ 104 ] A blood sample after 12-hours of fasting is taken by a healthcare professional from an arm vein to measure a lipid profile for a) total cholesterol, b) HDL ...
Elevated low-density lipoprotein (aka “bad cholesterol”) The men also had elevated total cholesterol. Beyond this, 60 percent of the women in this group had an abdominal circumference of ...
LDL circulates and is absorbed by the liver and peripheral cells. Binding of LDL to its target tissue occurs through an interaction between the LDL receptor and apolipoprotein B-100 on the LDL particle. Absorption occurs through endocytosis, and the internalized LDL particles are hydrolyzed within lysosomes, releasing lipids, chiefly cholesterol.
Guidelines by the American College of Cardiology and the American Heart Association recommend statin treatment for primary prevention of cardiovascular disease in adults with LDL cholesterol ≥ 190 mg/dL (4.9 mmol/L) or those with diabetes, age 40–75 with LDL-C 70–190 mg/dL (1.8–4.9 mmol/dL); or in those with a 10-year risk of developing ...
