Abstract

Rationale: Familial hypercholesterolemia (FH) predisposes patients to premature cardiovascular disease, with the process of atherosclerosis initiated in early childhood.
Objective: As part of an ongoing trial to assess the efficacy and safety of rosuvastatin in children with FH aged 6 to 17 years, we report the differences in carotid intima-media thickness (cIMT) at baseline between children with FH and their unaffected siblings.
Methods and Results: B-mode ultrasound measurements of the carotid artery were made in 196 children with FH and 64 of their siblings. Mean (±SE) cIMT in children with FH was significantly greater than that of unaffected siblings (0.398±0.052 versus 0.377±0.045 mm; P<0 .001="" 8="" a="" age="" analyses="" and="" before="" cimt.="" cimt="" fh="" greater="" independent="" male="" multivariable="" observed="" of="" p="" predictors="" presence="" sex="" showed="" significantly="" that="" the="" value="" was="" were="" years.="">

Conclusions: 
 The difference in mean cIMT between children with FH and their unaffected siblings may be significant as early as age 8 years.
 This study confirms the need for early cholesterol lowering in this high-risk population. 
These patients participating in a carefully monitored study will help assess the long-term efficacy on cIMT and safety of statin therapy in young children.
