title: Relation of high-density lipoproteins to coronary artery disease.
abstract: Low mean concentrations of high-density lipoprotein (HDL) cholesterol have long been recognized as a characteristic of patients with coronary heart disease, and the measurement of this fraction is a relatively strong discriminator between patients with coronary heart disease and those without. When subjects are ranked by the severity of coronary atherosclerosis determined angiographically, levels of HDL cholesterol, particularly of its HDL2 subclass, are consistently lower in subjects with extensive disease than in those with minimal atheroma. HDL cholesterol is derived from a number of sources, mobilization from peripheral tissues being but one. Generally, longitudinal studies have confirmed that a low HDL cholesterol level is potently and independently predictive of a high risk of coronary heart disease, one exception being a study of subjects with hypercholesterolemia. Despite the strength of these epidemiologic associations, there is no evidence from experimental studies or clinical trials to establish that low HDL levels are causally important in atherogenesis.
