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]
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).
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 ...
LDL-C is not a measurement of actual LDL particles. LDL-C is only an estimate (not measured from the individual's blood sample) of 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.
In addition to plaque formation, LDL-C molecules can undergo oxidation. [1] Oxidation can cause further accumulation of cholesterol and the release of inflammatory cytokines, which damages the blood vessels. [1] [7] Due to the damaging effects of LDL-C, high levels increase the risk for cardiovascular disease and indicate dyslipidemia. [1]
Genetic studies indicate that if the levels of LDL cholesterol were reduced by just 0.35 mmol/L, then over a lifetime, this would equate to a 21% lower relative risk of atherosclerotic ...
Feb. 13—Sweating, nausea, dizziness and unusual fatigue may not sound like typical heart attack symptoms. However, they are common for women and may occur more often when resting or asleep.
Cholesterol is a sterol, a steroid-like lipid made by animals, including humans.The human body makes one-eighth to one-fourth teaspoons of pure cholesterol daily. A cholesterol level of 5.5 millimoles per litre or below is recommended for an adult.
