Detection of Four Cases of Familial Hypercholesterolemia during a Workers' Compensation Insurance Secondary Health Examination

Familial hypercholesterolemia (FH), a genetic disorder characterized by the early onset of coronary artery disease, is found in one of 300 people. In the 2022 Japanese FH guidelines, a cut-off value for Achilles tendon thickness measured using ultrasound has been added, enabling the diagnosis of FH during a Workers' Compensation Insurance Secondary Health Examination. In individuals for whom the possibility of FH could not be ruled out based on low-density lipoprotein cholesterol levels, we measured the Achilles tendon thickness by ultrasound and found four cases of FH. The detection of FH in asymptomatic workers is crucial for long-term cardiovascular risk management.
