Proprotein convertase subtilisin/kexin type 9 (PCSK9) comprised of 692 amino acids is the ninth member of protease family. It binds to the low-density lipoprotein receptor(LDLR), leading to elevated levels of circulating low-density lipoprotein cholesterol(LDLC), which can lead to a number of cardiovascular diseases, and among then the relationship with cardiovascular calcification has recently received attention. Cardiovascular calcification is a kind of ectopic mineralisation in the cardiovascular system, which is mainly characterised by the production of mineral deposits in the vascular wall and vascular valves, and its pathogenesis is related to lipoprotein content, platelet activity, matrix vesicle (MV) release and inflammation, through which PCSK9 may be involved in the occurrence of cardiovascular calcification.Therefore, this article reviews the relationship between PCSK9 and cardiovascular calcification, emphasizing the specific role of PCSK9 in affecting cardiovascular calcification through various pathways, assisting in setting up emerging applications of PCSK9 amid vessel biological science and recognize innovative molecular mechanisms for its treatment.
