Familial Combined Hyperlipidemia (FCHL) is a common genetic subtype of the metabolic syndrome characterized by disproportionately elevated Apo B levels, which significantly increases the risk of premature coronary artery disease compared to the metabolic syndrome alone.

If you have metabolic syndrome, ask your doctor to check your Apo B levels. If they are high, you may have Familial Combined Hyperlipidemia (FCHL), a genetic condition that puts you at much higher risk for heart disease than metabolic syndrome alone. This diagnosis is crucial because it often requires more aggressive treatment, such as lipid-lowering therapy, to prevent heart attacks.

The second, familial combined hyperlipidemia, accounts for an additional 10–20% of premature CAD. Familial combined hyperlipidemia is characterized by the metabolic syndrome in addition to a disproportionate elevation of apolipoprotein B levels.
