What is pure hypercholerosterolemia? is it the same as familial hypercholesterolemia?

May be: essentially it means in your lipid profile it's the Cholesterol or LDL is elevated. It may be genetic or due to lifestyle, either way it needs to be treated, and best that works are the Statins( Lipitor, (atorvastatin) creator, simvastatin). Also diet and excercise. Important to bring to below normal since it increases your risk of Heart disease or Coronary diseases.
