Lipoprotein (a)

LP(a) is another LDL particle, but it also has another apolipoprotein on it called apolipoprotein a. LP(a) particle is perhaps the most atherogenic particle in the body, and while it’s included in the total of LDL particle numbers, it is important to know if somebody has an elevated LPL(a) particle number, because that in and of itself, independent of the total LDL particle number, is an enormous predictor of risk, and something which needs acting on (via diet – medication is ineffective).

The Lp(a) test is used to measure the blood level of small dense lipoproteins, which are a direct link to the formation of arterial plaques (atherosclerosis), and is a strong indicator for coronary heart disease: Elevated blood levels of lipoprotein are associated with increased risk of cardiac death in individuals with a history of acute heart attacks and coronary bypass procedures. Lp(a) also increases your risk for coronary heart disease and ischemic stroke.

By checking Lp(a) you learn about how many destructive LDL particles are in your blood and in this test, the aim is to determine their size/density.
