The EAS FHSC is an international initiative involving a network of investigators interested in FH from around 70 countries.• Information on FH prevalence is lacking in most countries; where available, data tend to align with contemporary estimates.• FH diagnosis and management varies widely across countries, with overall suboptimal identification and under-treatment.• In most countries diagnosis primarily relies on DLCN criteria, and less frequently on Simon Broom or MEDPED.• Therapy for FH is not universally reimbursed, and criteria vary across countries. Access to PCSK9i and apheresis is limited.

The EAS FHSC represents an excellent opportunity to integrate individual efforts across the world to tackle the global burden of FH. The information garnered from the registry will help reduce gaps in knowledge, inform best practices, assist in clinical trials design, support clinical guidelines and policies development, and ultimately improve the care of FH patients.
