	Cholesterol - Wikipedia, the free encyclopedia
		Cholesterol is a steroid, a lipid, and an alcohol, found in the cell membranes of all body tissues, and transported in the blood plasma of all animals.
		Cholesterol plays a central role in many biochemical processes, but is best known for the association of cardiovascular disease with various lipoprotein cholesterol transport patterns in the blood.
		Cholesterol is excreted from the liver in bile and reabsorbed from the intestines.

	HDL Cholesterol: The Test
		The test for HDL cholesterol is used along with other lipid tests to determine your risk of heart disease.
		HDL is usually ordered with other tests, including cholesterol, LDL, and triglycerides as part of a lipid profile.
		HDL should be interpreted in the context of the overall findings from the lipid profile and in consultation with your doctor.

	High cholesterol level (hypercholesterolaemia)
		Cholesterol and another lipid, triglyceride, are important building blocks in the structure of cells and are also used in making hormones and producing energy.
		When the cholesterol level is measured in a blood sample (taken after the patient has fasted for several hours), the levels of all forms of cholesterol can be calculated.
		High cholesterol is also seen in connection with other diseases, such as reduced metabolism (due to thyroid hormone problems, for example), kidney diseases, diabetes and alcohol abuse.

	Cholesterol: What the HDL/LDL Ratios Mean (Site not responding. Last check: 2007-10-08)
		HDL and LDL are two different kinds of cholesterol that are measured as an index of a patient's risk for cardiovascular disease.
		The levels of "fats" in the blood-total cholesterol, HDL (a subset called "good cholesterol") and LDL ("bad cholesterol") and triglycerides have been used for years to predict the risk of heart disease in men.
		If a woman's total cholesterol is about 4 times or so of her HDL level, her risk of heart disease skyrockets to up to five times that of her normal counterpart.

	Fats & Cholesterol: Nutrition Source, Harvard School of Public Health
		HDL makes it less likely that excess cholesterol in the blood will be deposited in the coronary arteries, which is why HDL cholesterol is often referred to as the "good" cholesterol.
		While it is well known that high blood cholesterol levels are associated with an increased risk for heart disease, scientific studies have shown that there is only a weak relationship between the amount of cholesterol a person consumes and their blood cholesterol levels or risk for heart disease.
		Butter was known to be filled with cholesterol and saturated fat that were bad for blood cholesterol and increased the risk of heart disease.

	HDL cholesterol definition - Cholesterol: health and medical information about high cholesterol and heart disease
		HDL cholesterol: Lipoproteins, which are combinations of lipids (fats) and proteins, are the form in which lipids are transported in the blood.
		The high-density lipoproteins transport cholesterol from the tissues of the body to the liver so it can be gotten rid of (in the bile).
		Medications that are effective in increasing HDL cholesterol include nicotinic acid (niacin), gemfibrozil (Lopid), estrogen, and to a lesser extent, the statin drugs.

	Cholesterol: medical information about high cholesterol, lowering cholesterol levels and heart disease
		Cholesterol is a fatty substance (a lipid) that is an important part of the outer lining (membrane) of cells in the body of animals.
		After a meal, cholesterol is absorbed by the intestines into the blood circulation and is then packaged inside a protein coat.
		HDL cholesterol is called the "good cholesterol" because HDL cholesterol particles prevent atherosclerosis by extracting cholesterol from the artery walls and disposing of them through the liver.

		LDL cholesterol is used by your body to transport important fatty acids to your cells, which is a major source of energy for you.
		It is the job of your HDL cholesterol to find whatever excess LDL is still circulating in your blood stream and bring it back to the liver where it can be stored and released later as needed.

	HDL CHOLESTEROL
		Having low blood levels of the good HDL that prevents heart attacks is one of the strongest predictors of a person's susceptibility to suffer a heart attack, but only when a person is on a high-fat diet.
		Studies on the effect of low blood levels of the good HDL cholesterol on susceptibility to heart attacks were done on middle- aged Americans eating a high-fat diet.
		HDL cholesterol is good because it helps prevent heart attacks by carrying cholesterol from your bloodstream to your liver where it can be converted to bile and removed from your body/ before it can form plaques in arteries.

	MedlinePlus Medical Encyclopedia: HDL
		The HDL cholesterol is a test that measures the amount of high-density lipoprotein (HDL) cholesterol in serum.
		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.
		Higher levels of HDL seem to be protective against coronary artery disease, thus HDL is sometimes referred to as "good" cholesterol.

	What's the Difference Between LDL and HDL Cholesterol?
		If a clot forms and blocks a narrowed artery, it can cause a heart attack or stroke. The levels of HDL cholesterol and LDL cholesterol in the blood are measured to evaluate the risk of having a heart attack.
		LDL cholesterol of less than 100 mg/dL is the optimal level. Less than 130 mg/dL is near optimal for most people. A high LDL level (more than 160 mg/dL or 130 mg/dL or above if you have two or more risk factors for cardiovascular disease) reflects an increased risk of heart disease.
		HDL cholesterol is known as the "good" cholesterol because a high level of it seems to protect against heart attack.

		In contrast, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) repeatedly have been shown to reduce mean serum low-density lipoprotein cholesterol (LDL-C) concentrations by 28% to 35% in long-term trials, with corresponding reductions in cardiovascular death of 23% to 32% in both primary and secondary prevention trials.
