Last reviewed 01/2018

Individuals heterozygous for familial hypercholesterolaemia (FH) experience an increased risk of coronary heart disease and death from myocardial infarction (MI) in middle life.

  • if left untreated, men and women with heterozygous FH with total cholesterol levels of 8-15 mmol/L (310-580 mg/dL) typically develop CHD before age 55 and 60, respectively, while homozygotes with total cholesterol levels of 12-30 mmol/L (460-1160 mg/dL) typically develop CHD very early in life and if untreated die before age 20
  • however, once diagnosed, heterozygotes can readily be treated with cholesterol-lowering medication to attenuate development of atherosclerosis and to prevent CHD
