Lipoprotein(a) [Lp(a)] has been identified as a risk factor for cardiovascular disease. Lp(a) levels are also high under certain clinical conditions, including familial hypercholesterolemia and high blood low-density lipoprotein (LDL) cholesterol levels. Few effective generic therapies for modulating Lp(a) have been developed. However, new therapies involving inhibitors of proprotein convertase subtilisin/kexin type 9 (PCSK9) using monoclonal antibodies have markedly reduced the blood LDL levels-and the Lp(a) levels as well. Much attention has therefore been focused on this therapy and its utility. The mechanism by which PCSK9 inhibitors reduce the Lp(a) levels remains unclear. We here describe the effects of PCSK9 inhibitors on Lp(a) and discuss potential mechanisms and perspectives of this topic.
脂蛋白(a)[Lp(a)]已被确定为心血管疾病的一个危险因素。在某些临床情况下,包括家族性高胆固醇血症和血液低密度脂蛋白(LDL)胆固醇水平升高时,Lp(a)水平也会升高。目前很少有有效的通用疗法来调节Lp(a)。然而,使用单克隆抗体的涉及前蛋白转化酶枯草杆菌蛋白酶/kexin 9型(PCSK9)抑制剂的新疗法显著降低了血液LDL水平,同时也降低了Lp(a)水平。因此,人们对这种疗法及其效用给予了极大关注。PCSK9抑制剂降低Lp(a)水平的机制尚不清楚。我们在此描述PCSK9抑制剂对Lp(a)的影响,并讨论该主题的潜在机制和前景。
