Primary source

Scientific Steering Committee on behalf of the Simon Broome Register Group. Risk of fatal coronary heart disease in familial hypercholesterolaemia. BMJ. PMID: 1933004. Definite FH is the cholesterol threshold plus tendon xanthomas in the patient or a first- or second-degree relative, or a DNA mutation. Possible FH is the cholesterol threshold plus a family history of myocardial infarction or of raised cholesterol. Adult thresholds are total cholesterol >7.5 mmol/L or LDL >4.9 mmol/L; child thresholds are >6.7 and >4.0 mmol/L. (1991)
