<prompt> Good cholesterol found in: PGI Dec 2007HDLLDLVLDLIDL  <response>: Ans. A H DL HDL contains good cholesterolQ So there is an inverse relation between HDL concentration and coronoary heart disease. This is consistent with the function of HDL in reverse cholesterol transport. Diseases eg. diabetes mellitus, lipid nephrosis, hypothyroidism and other conditions of hyperlipedimea in which prolonged elevations of VLDL, IDL, LCD or chylomicron remnants in blood are often accompanied by premature or severe atherosclerosis0. This makes LDL : HDL cholesterol ratio a good predictive for atherosclerosis coronary heart disease.Frederickson Classification of Hyper LipoproteinemiasPhenotypeIIIaIIbIIIVVLaboratory FeaturesLipoprotein, elevatedChylomicronsQLDLQLDL and VDLChylomicrons and VLDL remnantsVLDLChylomicrons and VLDLTriglycerides-- to Cholesterol to Q to to -- to to LDL-cholesterolHDL-cholesterolPlasma appearanceLactescentClearClearTurbidTurbidLactescentClinical FeaturesXanthomasQEruptiveTendon, tuberousNonePalmar, tuberoeruptiveNoneEruptivePancreatitis0000Coronary atherosclerosis0--Peripheral atherosclerosisQ0--Molecular defect Genetic nomenclatureMolecular defectsLPL and apo-C-IILDL receptor.
