Fatal Familial Cholesterol Disease Overlooked

Recently, direct screening in a Northern European general population diagnosed approximately 1 in 200 with heterozygous FH. All reported studies document failure to achieve recommended LDL cholesterol targets in a large proportion of individuals with FH, and up to 13-fold increased risk of CHD.

Based on prevalence between 1 in 500 and 1 in 200, between 14 and 34 million individuals worldwide have FH. The investigators recommend that children, adults, and families should be screened for FH if a person or family member presents with FH, a plasma cholesterol level in an adult of equal to or greater than 8 mmol/L (≥ 310 mg/dL) or a child with equal to or greater than 6 mmol/L (≥ 230 mg/dL), premature CHD, tendon xanthomas, or sudden premature cardiac death. The FH condition can be confirmed with a gene test.

In FH, low-density lipoprotein cholesterol targets are less than 3.5 mmol/L (<135 mg/dL) for children, and less than 2.5 mmol/L (<100 mg/dL) for adults, and less than 1.8 mmol/L (<70 mg/dL) for adults with known CHD or diabetes. M. John Chapman, PhD, DSc, a professor at the Pitié-Salpetriere University Hospital (Paris, France) and a senior author of the study said, “It is surprising and sad that even rich countries with highly developed health systems fail to help these people. It is not a question of economic resources, as the disease is easy to diagnose and inexpensive to treat.” The study was published online on August 15, 2013, in the European Heart Journal.
