This is a major problem as the disease is dangerous for health. However, this disease is easy to diagnose and treat, according to the conclusion of a consensus report from the European Atherosclerosis Society. The report was recently published in the recognised medical journal European Heart Journal.
A new consensus report documents massive underdiagnosis and undertreatment of hereditary high blood cholesterol – so-called familial hypercholesterolaemia – in practically all 200 countries in the world, the only exceptions being the Netherlands and Norway.
Fatal cholesterol disease overlooked and untreated
Between 14 and 34 million people worldwide are estimated to suffer from familial hypercholesterolaemia.
"In most countries, the number of people with familial hypercholesterolaemia is unknown. This means that the condition is not detected until the person develops heart disease or dies suddenly far too young. Considering how easily the disease can be prevented, this situation is an admission of failure from a health perspective," says Børge Nordestgaard, Clinical Professor at the Faculty of Health and Medical Sciences, University of Copenhagen, and Chief Physician at Copenhagen University Hospital. He is the leading author of the new consensus report, which has been published in the European Heart Journal.
"In the general population, between 1 in 200 and 1 in 500 people inherit the disease familial hypercholesterolaemia, making the disease the most frequent hereditary and fatal disease. However, statins, which are safe and inexpensive treatments, can lower cholesterol levels. For these persons with a greatly increased risk of developing serious heart disease, the few side effects associated with statins are negligible," says Børge Nordestgaard.
Between 14 and 34 million people worldwide are estimated to suffer from familial hypercholesterolaemia. In Europe, the number is between 1.8 and 4.5 million and, in Denmark, between 11,000 and 28,000. These figures are based on the large Copenhagen General Population Study.
"In the Netherlands and Norway, most people suffering from familial hypercholesterolaemia have been identified, and are offered cholesterol-lowering treatment with statins. In Denmark, only an estimated 500 persons with familial hypercholesterolaemia have been identified and undergone sufficient treatment," says Børge Nordestgaard.
Easy to diagnose
Familial hypercholesterolaemia is easy to diagnose; it only requires a blood cholesterol test and a family history of early-onset heart disease. Cholesterol levels above 8 mmol/L in adults and above 6 mmol/L in children are a strong indication of the condition, and the diagnosis can be confirmed by a gene test.
"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," says Professor John Chapman. He is one of the co-authors of the report and Professor at the Pitié-Salpêtrière university hospital in Paris.
Coordinated national effort required
According to Børge Nordestgaard, a coordinated national effort is required, with clinics at all major hospitals in most countries, similar to the existing diabetes clinics.
"It would also improve the registration of familial hypercholesterolaemia and the families affected if the WHO decided to assign the disease its own diagnostic code as is the case with diabetes," Børge Nordestgaard concludes.

The European Atherosclerosis Society Consensus Panel, comprised of 28 internationally renowned experts in atherosclerosis and cardiovascular disease, convened twice to consider the current evidence-base for familial hypercholesterolaemia. The Panel is co-chaired by Professor John Chapman, Pitié-Salpetriere University Hospital, Paris, France and Professor Henry Ginsberg, Columbia University, New York, USA.

A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time.
It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light.
Scaling up this new design from its tablet-size prototype to a full-size solar panel would be a large step toward making solar power affordable compared with ...
Atlantische Flohkrebse pflanzen sich jetzt auch in arktischen Gewässern fort
Biologen des Alfred-Wegener-Institutes, Helmholtz-Zentrum für Polar- und Meeresforschung (AWI), haben zum ersten Mal nachgewiesen, dass sich in den arktischen Gewässern westlich Spitzbergens auch Flohkrebse aus dem wärmeren Atlantik fortpflanzen.
Diese überraschende Entdeckung deute auf einen möglichen Wandel der arktischen Zooplankton-Gemeinschaft hin, berichten die Wissenschaftler und Wissenschaftlerinnen in der Fachzeitschrift Marine Ecology ...
The molecular architecture of three key proteins and their complexes reveals how plants fine-tune their immune response to pathogens
Plants rarely get sick in their natural environment. When the threat of infection arises, a quick decision is made about the necessary countermeasures. The course is set by a protein which forms complexes with its partner proteins for this purpose.

Researchers studying speciation of butterfly orchids on the Azores have been startled to discover that the answer to a long-debated question "Do the islands support one species or two species?" is actually "three species".
Hochstetter's Butterfly-orchid, newly recognized following application of a battery of scientific techniques and reveling in a complex taxonomic history worthy of Sherlock Holmes, is arguably Europe's rarest orchid species. Under threat in its mountain-top retreat, the orchid urgently requires conservation recognition.

Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon's largest impact crater.
Data from the Moon Mineralogy Mapper that flew aboard India's Chandrayaan-1 lunar orbiter shows a diverse mineralogy in the subsurface of the giant South Pole Aitken basin.
The differing mineral signatures could be reflective of the minerals dredged up at the time of the giant impact 4 billion years ago, ...
