Figure 3. Cumulative LDL cholesterol Exposure in Familial Hypercholesterolemia Mutation Carriers Compared on Non-carriers Matched on LDL cholesterol at Ascertainment.
Hypercholesterolemic [low-density lipoprotein (LDL) cholesterol ≥ 130 mg/dl] carriers of a familial hypercholesterolemia (FH) mutation were identified in the Atherosclerosis Risk in Communities (ARIC) and Framingham Heart Study (FHS) Offspring cohorts and matched 1:1 to a FH mutation non-carriers according to age, gender, statin use, and LDL cholesterol at time of ascertainment. Mean ± standard error (SE) LDL cholesterol values at each study visit are displayed in each cohort according to mutation status. A matched pairs t-test demonstrated higher cumulative exposure to LDL cholesterol in FH mutation carriers versus non-carriers.
