Familial hypercholesterolemia: Although identification advances, appreciation and treatment lag

Abstract

Familial hypercholesterolemia is one of the most common autosomal dominant inherited genetic disorders, yet it is frequently undiagnosed, leading to a markedly increased risk for cardiovascular events. Understanding the pathophysiology of the disease as well as the importance of cascade screening is critical to appropriate treatment of patients. Though the mainstay of therapy for heterozygous familial hypercholesterolemia remains statins, many patients require additional therapy including ezetimibe and/or proprotein convertase subtilisin/kexin type 9 (PCSK9) antibodies to achieve adequate low-density lipoprotein cholesterol (LDL-C) lowering. Access to PCSK9 inhibitors remains a significant clinical problem.
