Clinical Significance

Aid in the identification of individuals at risk from cardiovascular disease in specific populations when used in conjunction with clinical evaluation.

The measurement of Lipoprotein(a), in conjunction with other lipoprotein tests, is of diagnostic significance when assessing atherosclerotic cardiovascular disease in specific populations. Elevated Lp(a) levels are associated with coronary heart disease, cerebrovascular disease (stroke), and peripheral vascular disease. Lp(a) is a heterogeneous family of lipoprotein particles consisting of an apolipoprotein(a) molecule attached to an apolipoprotein B-100 and a lipid-rich LDL-like core. Lp(a) levels are genetically determined and remain relatively stable over an individual's lifetime. An elevated blood concentration of Lp(a) is associated with increased risk for myocardial infarction, stroke, coronary artery disease, vein graft restenosis, and retinal arterial occlusion. Lp(a) levels above 30 mg/dL represent a twofold relative risk for the development of atherosclerotic disease.
