Patients older than 18 years old and have a serum low density LDL-C≥250 mg/dL were identified from the hospital database. A questionnaire was completed via phone. Patients were classified as definite, probable and possible familial hypercholesterolemia according to Dutch Lipid Clinical Network Criteria
Familial hypercholesterolemia is a genetic disease characterized by increased levels of low density lipoprotein cholesterol (LDL-C). It is underdiagnosed and undertreated despite relatively high prevalence and significant association with increased mortality.
