Lipoprotein(a) or Lp(a) is a type of lipoprotein particle found in the blood that is composed of an apolipoprotein(a) attached to a low-density lipoprotein (LDL) particle. Lipoprotein(a) is produced in the liver and is believed to play a role in the transport of lipids in the body.

The levels of lipoprotein(a) in the blood have been linked to an increased risk of cardiovascular disease, particularly coronary artery disease and stroke. High levels of Lp(a) are believed to contribute to the formation of atherosclerotic plaques and the development of thrombosis. Furthermore, elevated levels of Lp(a) have also been associated with an increased risk of peripheral artery disease and sudden cardiac death.

Lipoprotein(a) also has a role in inflammatory processes in the body. The apolipoprotein(a) part of the particle has been shown to bind to certain glycoproteins and stimulate the release of pro-inflammatory cytokines.

The genetics of lipoprotein(a) are complex and involve multiple genes. The gene encoding apolipoprotein(a) has a high degree of polymorphism, which can lead to variations in the level of Lp(a) in the blood. Familial hypercholesterolemia, a condition characterized by very high levels of LDL cholesterol, can also lead to high levels of Lp(a).

There is currently no established treatment or intervention for high levels of lipoprotein(a). However, certain medications such as statins and ezetimibe may help to lower Lp(a) levels. Research is ongoing to better understand the role of Lp(a) in disease and to develop targeted therapies for high levels of this lipid particle.
