We appreciate the comments of Dr Koh regarding our recent publication in Circulation.1 We comment here on the issues raised.

However, from what age exactly and to what extent low-density lipoprotein (LDL) cholesterol (LDL-C) should be lowered remain difficult questions, and the answers are probably different for each individual because many factors contribute to cardiovascular risk. From the baseline data of the CHARON trial (Hypercholesterolemia in Children and Adolescents Taking Rosuvastatin Open Label), the difference in carotid intima-media thickness (c-IMT) between subjects with HeFH and unaffected siblings was shown to be significant before the age of 8 years.2 This finding may suggest that statins should be started possibly from a younger age than is currently recommended because treatment should preferably be started before the process of atherosclerosis is detectable.
