Like many complex disease processes, atherogenesis represents the inte
raction of an array of genetic and environmental factors. From nonhuma
n animal models to the investigation of epidemiologic factors in man,
no single, overriding cause for the development of this indolent vascu
lar disease has been identified. However, the cholesterol-enriched lip
oprotein particles are closely tied to the development of the disease.
The genetic and environmental influences on the concentrations of spe
cific Lipoprotein subspecies provide a context for identifying patient
s at risk as well as for developing effective therapeutic strategies t
o influence and prevent the sequelae of atherogenesis.
