Lp(a)
Lipoprotein(a) – genetically determined cardiac risk marker
Also known as
Lipoprotein a Lipoprotein(a) Lp(a) cholesterol
Definition
Lipoprotein(a) is an LDL-like particle carrying an additional apolipoprotein(a) moiety and is strongly genetically determined. Elevated Lp(a) levels are an independent, causally established risk factor for myocardial infarction, stroke, and aortic valve stenosis. Because Lp(a) is largely unresponsive to lifestyle changes, testing primarily serves risk stratification and treatment decision-making.
