This is a genotype with recommended actions if clinically confirmed. In brief:
- FH (familial hypercholesterolemia) is characterized by high low-density lipoprotein cholesterol (LDL-C) and increased risk of premature coronary artery disease; untreated LDL-C concentrations are typically in the range of 190-350 mg/dL.
- These raised LDL-C concentrations are likely to be present during childhood and may lead to early development of atherosclerosis and coronary heart disease (CHD) if left untreated.
- Patients should consider lifelong, high-intensity statin therapy beginning in childhood (age 8). Statin use in FH patients may reduce CHD risk by 76%.
- Consider taking aspirin daily.
- High blood pressure and diabetes are additional CHD risk factors and should be treated aggressively in FH individuals.
- Monitor blood pressure every 6 - 12 weeks and lipid levels at least annually.
- FH patients should avoid additional risk factors for CHD including smoking, physical inactivity, diets high in saturated fats and cholesterol, unhealthy body weight, and excessive alcohol consumption.
- Consider LDL-C or genetic testing of family members.
