Impact of clinical signs and genetic diagnosis of familial hypercholesterolaemia on the prevalence of coronary artery disease in patients with severe hypercholesterolaemia

摘要

Aims The impact of positive clinical signs (xanthoma and/or family history) and positive familial hypercholesterolaemia (FH) mutation status on risk of coronary artery disease (CAD) over and above that predicted by low-density lipoprotein (LDL) cholesterol level alone has not been fully determined. We assessed whether positive clinical signs and genetic FH diagnosis affected CAD risk among subjects with significantly elevated LDL cholesterol levels (>= 180 mg/dL, or >= 140 mg/dL in subjects <15 years of age).
