Familial Hypercholesterolaemia (FH) is the most common of all severe familial disorders and its hallmark is high LDL-cholesterol in plasma. The disease is carried by one out of 200-300 persons in Europe – that is to say a total of about 2 million people in Europe carry FH. The disease is present from early childhood, but is carried without symptoms until the third or fourth decade in life, when heart disease will appear. If untreated, 50 percent of men will have had their first heart attack before the age of 50 years, and women before 55 years. To carry FH is to carry a ticking bomb that, if untreated, will cause cardiac disease or death.
