Familial Hypercholesterolemia

心内科

Common symptoms

血管杂音、结节、动脉粥样硬化、钙化、心绞痛

The pathology of disease

Familial hypercholesterolemia (FH) is an autosomal-dominant LDL-receptor (or ApoB/PCSK9) defect causing lifelong elevated LDL cholesterol. Heterozygous FH (~1/250): high LDL, tendon xanthomas, corneal arcus, premature coronary artery disease. Homozygous FH (~1/250,000): severe childhood hypercholesterolemia, cutaneous/tendon xanthomas, aortic stenosis, early myocardial infarction. Treatment: high-intensity statin, ezetimibe, PCSK9 inhibitors; LDL apheresis/liver transplant for homozygous.

Common Symptoms

High LDL cholesterol; tendon xanthomas; corneal arcus; premature coronary disease; family history; cutaneous xanthomas (homozygous)

Causes and Pathogenesis

LDL-receptor/ApoB/PCSK9 mutation impairs LDL clearance, causing lifelong elevated LDL and accelerated atherosclerosis.

Treatment

High-intensity statin; ezetimibe; PCSK9 inhibitor; LDL apheresis; liver transplant for homozygous; family cascade screening

Preventive Measures

Cascade family screening; early statin treatment; healthy diet; no smoking.
