Aortic Sclerosis

I just recieved an ecchocardiogram which showed a Mild Aortic Sclerosis. I see that recent research suggests this may not be as benign as once thought. I also have an elevated Cholesterol. HDL>90 but LDL 140! There seems to be a correlation between high LDL  contributing to this condition. If the LDL and or total Cholesterol are reduced by Diet and or Statins could the Sclerosis be reversed. I am a 60 year old female.
Also does this necessarily mean that I have ASHD,

There is some evidence that taking statins may prevent progression of  aortic stenosis.  I would definitely recommend taking statin in your situation regardless of what your cholesterol profile is.  Also, you are correct that there is an association between your type of aortic stenosis and coronary artery disease.  As long as you don't have any chest pain or shortness of breath your goal should be to concentrate on coronary risk factor modification.  Taking a statin will address the hyperlipidemia.  Also, make sure you don;t have any tobacco exposure, first or second hand, control your blood pressure and make sure that you are not a diabetic.
