High density lipoprotein - Wikipedia, the free encyclopedia High density lipoproteins (HDL) form a class of lipoproteins, varying somewhat in their size and contents, that carry cholesterol from the body's tissues to the liver. This ratio of large HDL to total HDL particles varies widely and is only measured by more sophisticated lipoprotein assays using either electrophoresis, the original method developed in the 1970s or newer NMR spectroscopy methods, developed in the 1990s. Because HDL can remove cholesterol from atheroma within arteries, and transport it back to the liver for excretion, they are seen as "good" lipoproteins. en.wikipedia.org /wiki/HDL_cholesterol

HDL The HDL cholesterol is a test that measures the amount of high-density lipoprotein (HDL) cholesterol in serum. Lipoproteins are proteins in the blood that transport cholesterol, triglycerides, and other lipids to various tissues. The main function of HDL appears to be carrying excess cholesterol (and probably other phospholipids and proteins) to the liver for "re-packaging" or excretion in the bile. www.healthscout.com /ency/1/003496.html

Hdl cholesterol High density lipoproteins (HDL) form a class of lipoproteins, varying somewhat in their size and contents, that carry cholesterol from the body's tissues to the liver. High blood cholesterol is one of the major risk factors for heart disease. Chromium supplements increased HDL cholesterol levels by an average of nearly 6 points, a 16 percent increase. health.hrum.com /info-hdl-cholesterol.html

High-Density Lipoprotein (HDL) HDL is produced in the liver and intestines. A ratio of total serum cholesterol to HDL level is sometimes used to look at the risk of CAD. HDL levels form an inverse correlation with the risk of CAD. mobile.neulabs.com /labstudies/hdl.asp

VascularWeb: High-density Lipoprotein Cholesterol Inversely Related NEW YORK (Reuters Health) - High-density lipoprotein (HDL) cholesterol level is inversely associated to the risk of thromboembolic stroke in elderly men, according to a new study. Low, intermediate, and high HDL cholesterol levels were found in 17.8%, 58.5%, and 23.7% of men, respectively. The researchers examined the association between HDL cholesterol levels and stroke risk in 2444 men between the ages of 71 and 93 years who were enrolled in the Honolulu Heart Program. www.vascularweb.org /_CONTRIBUTION_PAGES/Medical_News_Reuters/HDL_Cholesterol_Inversely_Related.html

American Family Physician: Managing Low High-Density Lipoprotein Cholesterol Levels HDL is a class of particles containing lipids (phospholipids, cholesterol and triglycerides) and proteins (apolipoproteins, enzymes and lipid transfer proteins). Genetically determined high levels of HDL are associated with longevity and a decreased incidence of coronary artery disease. High dosages of statins may be useful in patients with moderately elevated triglyceride levels but not in patients with severe elevations. www.findarticles.com /p/articles/mi_m3225/is_5_60/ai_57437010

Lipids Online Slides: high-density lipoprotein cholesterol, cholesterol High-density lipoprotein (HDL) facilitates the removal of unesterified cholesterol from cells; the cholesterol is then esterified by the action of the lipoprotein-associated enzyme lecithin:cholesterol acyltransferase (LCAT). Tangier disease is probably associated with some increased risk of premature atherosclerotic vascular disease, but this risk does not seem to be proportional to the markedly decreased high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-I (apoA-I) levels. Elevated high-density lipoprotein cholesterol (HDL-C) is epidemiologically associated with a decreased risk of coronary artery disease. www.lipidsonline.org /slides/slide01.cfm?tk=10&pg=2

HDL (High-Density Lipoprotein, Good Cholesterol) An HDL test measures the level of high-density lipoprotein, or HDL, in the blood. HDL is known as the good carrier for cholesterol. The HDL test is generally done along with a total cholesterol and LDL test. www.3-rx.com /hdl/default.php

Adult Health Advisor 2005.2: High-Density Lipoprotein (HDL) Cholesterol Test HDL is called good cholesterol because having high levels of HDL in your blood reduces your risk of heart disease. The HDL test helps check your risk for heart disease or atherosclerosis, which is a hardening, narrowing, or blockage of the arteries. HDL makes it harder for the LDL to stick to the walls of your blood vessels and cause disease. www.med.umich.edu /1libr/aha/aha_hdlchole_crs.htm

Good Cholesterol vs. Bad Cholesterol Two lipoproteins you may have heard about are high-density lipoprotein, or HDL cholesterol, and low-density lipoprotein, or LDL cholesterol. High-density lipoprotein, or HDL cholesterol, is called “good cholesterol” because it is believed to remove cholesterol from the blood. Low-density lipoprotein, or LDL cholesterol, is known as “bad cholesterol.” Excess LDL builds up in your arteries and may lead to heart disease. www.forcholessterol.com /cwp/appmanager/for_cholessterol/for_cholessterolDesktop?_nfpb=true&_pageLabel=FC_goodVsBad

High density lipoprotein : Hdl cholesterol High Density Lipoprotein (HDL) is a class of blood lipoproteins. Epidemiological studies show that high concentrations of HDL (over 60 mg%) have protective value against cardiovascular diseases (ischemic stroke, myocardial infarct etc.) and low concentrations of HDL (below 35mg%) are a positive risk factor for these diseases, especially for women. High HDL level, optimal condition considered protective against heart disease www.city-search.org /hd/hdl-cholesterol.html

Diabetic Life - Adding Fiber May Help Diabetics Researchers found that fiber supplements lower levels of "bad" low-density lipoprotein (LDL) cholesterol and increase levels of "good" high-density lipoprotein (HDL) cholesterol in people with this type of diabetes. High blood cholesterol is considered a risk factor for cardiovascular disease, and it already had been established that fiber supplements could help reduce blood cholesterol levels in the general population. Their total blood cholesterol, triglycerides, LDL, and HDL were measured at the start of the study and again after 90 days. www.diabeticlife.org /ms/news/525369/main.html

HDL-C (High-density lipoprotein cholesterol) The cholesterol carried in high-density lipoprotein (HDL) is ‘good’ cholesterol, because it’s being taken away from the body tissues back to the liver. Conversely, LDL (low-density lipoprotein)-cholesterol is being transported from the liver to the rest of the body and increases the risk of CHD by leading to the formation of fatty deposits in the arteries. You could check your cholesterol level with a fingerprick test at your doctor’s surgery, on the high street or even at home with a d.i.y. www.heartuk.org.uk /artman/publish/article_280.shtml

High Density Lipoprotein The chart above provides a visual comparison of high density lipoprotein breakdown in three categories: low, normal and desirable. However, the vast majority of the women displayed either normal or high levels of HDL in the serum and have low risk of heart disease. The majority of the men who participated in this study exhibited low HDL values and may be at risk for future cardiovascular disease. www.ku.edu /~lba/HDL.htm

News - Low High-Density Lipoprotein Cholesterol a Risk Factor for Stroke in Elderly Patients Dutch researchers report that low high-density lipoprotein (HDL) cholesterol is a risk factor for coronary artery disease-related or stroke-related death in patients older than 85 years. Data on lipoproteins were available for 561 participants; lipid and lipoprotein levels could not be determined in 38 patients. The researchers say the study results show that low levels of total, LDL, and HDL cholesterol are all associated with increased mortality risk, which puts in question the necessity of cholesterol-lowering therapy in the elderly. www.docguide.com /news/content.nsf/news/8525697700573E1885256D6A006792B3

Consensus Statement: Triglyceride, High Density Lipoprotein, And Coronary Heart Disease It is apparent, as in most lipoprotein fractions, that HDL is a heterogeneous collection of particles of differing size and composition and that subpopulations of HDL are altered in many of the dyslipidemias. It recommended that HDL cholesterol be measured in all patients with high blood cholesterol (≥ 240 mg/dL) and in those patients with borderline high blood cholesterol (200-239 mg/dL) who had definite CHD or two other CHD risk factors (one of which could be male sex). The report noted the possible benefit of raising HDL concomitant with reducing elevated LDL; however, drug therapy was not advocated specifically to raise HDL cholesterol in patients without high LDL cholesterol levels. vidyya.com /archives/1230_4.htm
