While healthy diet and exercise are cornerstones of treatment, and are certainly important for our kids, I do agree that in selected cases medications such as statins would be beneficial. In some cases lifestyle changes are just not enough, and prior to statins we had no real effective treatment for these folks.
This would have to be in children with a strong family history of high cholesterol as well as having a seriously abnormal lipid profile themselves. The treatment would have to be monitored closely, as the drugs are clearly not without side effects. The almost lifetime length of exposure in such cases would also be a new twist in lipid management.
Autopsy studies in the past ( Korean conflict IIRC ) did show significant plaque formation in young service men, so we know that this disease begins early in life.
Obviously, this is not something that most kids would need.
