Beyond Lifestyle: Understanding Familial Hypercholesterolemia

Familial hypercholesterolemia (FH) is an inherited disorder impacting roughly one in 250 people worldwide. This condition means the liver cannot efficiently remove LDL cholesterol from the blood, leading to persistently high levels regardless of lifestyle.

Untreated FH silently accelerates atherosclerosis, significantly raising the lifetime risk of premature heart attack and stroke. An LDL cholesterol level of 190 mg/dL or higher in adults should prompt evaluation, especially with a family history of early heart disease.

While a heart-healthy lifestyle is essential, it often only modestly lowers LDL in FH patients. Medications, including statins, ezetimibe, and PCSK9 inhibitors, are frequently required. Special considerations are needed for women planning pregnancy, as statins are typically stopped before conception.

Post-menopause, women with FH face accelerating cardiovascular risk as estrogen's protection wanes. Early detection through family screening is vital, as most FH cases remain undiagnosed, highlighting the importance of asking about family history of early heart disease.
