"Atherosclerosis leads to condition like heart attack,stroke & etc.Prolong elevated plasma cholesterol more than 5.2mmol/L are believed to be major factor in promoting atherosclerosis but the initiating factors ; it's a whole different topic." "Why there are many other things in lipid profile other than just cholesterol?"he questioned. "Mainly there are triglycerides, cholesterol,HDL,and LDL.Sometime HDL &LDL ratio or Cholesterol and HDL ratio will be included.These are the main things but there are things like VLDL, IDL chylomicrons etc as well.HDL is a good lipid because excess tissue cholesterol will be returned to the liver by HDL while LDL will do the opposite.
Triglycerides is recognized as an independent risk factor itself.
Triglycerides lower HDL² levels and thereby exert indirect atherogenicity.
Regular exercise lowers plasma LDL and raises HDL. Triacylglycerol concentration are also reduced.
Patients with coronary atherosclerosis either have a defect in reverse cholesterol transport such as low HDL² levels or an excess in cholesterol load from diet which increases LDL, triglycerides."
