Numerous clinical studies and meta-analyses have shown that high lipoprotein (a) (Lp(a)) concentration is a continuous, independent, and moderately significant risk factor for ASCVD, and that this association is not dependent on LDL-C or non-HDL-C levels or other risk factors [<span>2</span>].</p><p>Lp(a) was first introduced to the scientific world by the Norwegian physician and geneticist Kare Berg in 1963 [<span>3</span>]. Lp(a) closely resembles LDL in terms of its protein and lipid composition, containing one molecule of apolipoprotein B (apoB) wrapped around a core of cholesterol esters and triglycerides with a surface of phospholipids and unesterified cholesterol particles. Lp(a) also contains a highly glycosylated protein called apo(a). This protein forms a covalent bond with apoB-100 via a single disulfide bond, which distinguishes Lp(a) from LDL.</p><p>Despite the fact that the structure of Lp(a) is similar to that of LDL, Lp(a) with a unique apo(a) is more atherogenic than LDL, and it is an attractive target for blood lipid intervention. The expert panel of the Beijing Heart Society has extended the systematic knowledge regarding Lp(a) beyond integrating the current global knowledge of Lp(a) and summarizing the evidence from Chinese populations. The scientific statement from Beijing Heart Society suggests key points for managing Lp(a) in Chinese populations for reference in clinical practice [<span>4</span>].</p><p>Lp(a) concentrations vary greatly among different races and geographic regions. In the Chinese population, Lp(a) concentrations have a skewed distribution with a median concentration of 5.6–8.0 mg/dL, which is slightly lower than that in Caucasians (9.0–17.0 mg/dL) but much lower than that in African Americans (33 mg/dL). Lp(a) concentrations are heritable, with total heritability of 68%–98%. The LPA gene (MIM 152200; ENSG00000198670) located on chromosome 6q27 encodes apo(a), and copy number variations in KIV-2 within the gene can range from 2 to 40 copies, which can explain 70%–90% of plasma Lp(a) concentrations [<span>5</span>].</p><p>In addition, single-nucleotide polymorphisms on the LPA gene are also associated with Lp(a) concentrations. The variant rs10455872 located in intron 25 and rs3798220 in the protease-like domain show the strongest correlation with Lp(a) concentrations, accounting for 22% of the variation in Lp(a) concentrations. However, these two single-nucleotide polymorphisms have not been found to be associated with Lp(a) concentrations in South Asian and Chinese populations [<span>6</span>].
