EAS Familial Hypercholesterolaemia Studies Collaboration (FHSC)
European Atherosclerosis Society Familial Hypercholesterolaemia Studies Collaboration
Familial hypercholesterolaemia (FH) is a common genetic disorder resulting in marked elevations in low-density lipoprotein cholesterol (LDL-C). If untreated, lifelong exposure to elevated LDL-C results in a substantially increased risk of (premature) cardiovascular disease as compared to the general population. Although FH adverse cardiovascular outcomes are potentially preventable through early identification of FH individuals and initiation of effective treatment, reports shows that FH is under-diagnosed and under-treated.
Efforts to tackle the global burden of FH have been hindered by a lack of global cohesion, with data held in disparate formats across many sites/countries, resulting in fragmentation and lack of harmonized data from different cohorts. A lack of structure and the availability of limited resources have made it hitherto difficult to integrate these cohorts thus far.
The EAS FHSC is a global initiative of stakeholders involved in the care of people living with FH that seeks to empower the medical and global community to seek changes in their respective countries or organisations to promote early diagnosis and effective treatment of FH. The FHSC Global Registry is a comprehensive, robust database of compiled secondary, unidentifiable, anonymised data on the burden of FH worldwide. These secondary data are sourced from multiple active national/regional/local registries across nearly 60 countries thus far, independent and external to the FHSC, and submitted to the FHSC Registry where data is standardised, pooled, harmonised and integrated into a single global database.
The FHSC Global Registry currently contains over 60,000 cases and remains active and will continue to receive secondary data over the years ahead. This multi-national pooled dataset facilitates clinical observational (non-interventional) studies to address multiple scientific inquires. This hypothesis-free epidemiology research will report on the characteristics of FH worldwide more accurately and inform the development of clinical guidelines and healthcare policy.

Detailed Description
Familial hypercholesterolaemia (FH) is a common genetic disorder affecting low-density lipoprotein cholesterol (LDL-C) metabolism, resulting in reduced catabolism of LDL particles and marked elevations in circulating LDL-C. If untreated, lifelong exposure to elevated LDL-C results in the development of atherosclerotic lesions early in life and a substantially increased risk of premature cardiovascular disease as compared to the general population. Early detection and effective treatment of FH can result in a significant improvement in clinical outcomes. Despite these compelling data, FH remains largely underdiagnosed with less than 5% of individuals with FH being identified in most regions around the world. Compounding its burden is the observation that FH is undertreated even among those with an established diagnosis.
The European Atherosclerosis Society (EAS) FH Studies Collaboration (FHSC) is a global initiative that was launched in 2015 to bring together a large-scale consortium of investigators and stakeholders involved in the care of people living with FH. The EAS FHSC ultimately seeks to empower the medical and global community to seek changes in their respective countries or organisations to promote early diagnosis and effective treatment of FH. The Coordinating Centre is based at the Imperial Centre for Cardiovascular Disease Prevention (ICCP), Imperial College London (ICL), UK. Currently investigators from over 65 countries are involved in the EAS FHSC network.
Specifically, the EAS FHSC aims to:
- Establish a worldwide, standardised registry of patients with FH by bringing together regional/national/international cohorts and registries with access to FH patients. This will allow the collaboration to maximise the exploitation of the data to accurately and reliably investigate (i) the burden of both homozygous FH (HoFH) and HeFH, (ii) how FH is detected and managed, (iii) the clinical consequences of current practice on delivery of care and outcomes, (iv) the factors that influence optimal management and LDL-C target attainment in FH.
- Disseminate the information gained from the registry to an international audience including physicians, other healthcare professionals, policy-makers and patients' organizations, to sensitise them to the contemporary burden of FH, encourage open discussion on FH management, promoting a uniform evidence-based standard-of-care, and encourage them to contribute actively to research.
- Consolidate a network of investigators interested in FH through which collaborative research and networking on FH can be conducted on a large-scale.
The FHSC Global Registry is a comprehensive, robust database of compiled secondary, unidentifiable, anonymised data on the burden of FH worldwide. These secondary data were sourced from multiple resources of active multiple cohorts, registries, databases and collections with access to information on individuals with a clinical and/or genetic diagnosis of homozygous or heterozygous FH across nearly 60 countries thus far, independent and external to the FHSC, and submitted to the FHSC Registry by the respective data suppliers where data is pooled, harmonised and integrated into a single global database. The FHSC registry has been conceived with a long term strategy in mind, in order to increase the follow-up of patients, including new individuals diagnosed with FH over time, bringing new cohorts into the registry, and take into account temporal trends and changes in clinical practice.
Quality assurance was addressed by providing the data suppliers with the FHSC protocol, which sets out the criteria of minimal standards for data collection prior to submission to the FHSC Global Registry, ensuring data completeness and accuracy. The incoming data was collated, standardised in accordance with a data dictionary, cleaned and validated by coordinating data queries with the respective data suppliers, and integrated within a secure data warehouse.
The FHSC Global Registry currently contains over 60,000 cases and remains active and will continue to receive secondary data over the years ahead. Standard validated statistical procedures and models for observational studies and weighted meta-analyses are being performed on the secondary data to address multiple scientific inquiries.
