前蛋白转化酶枯草杆菌蛋白酶/Kexin9型在心肌梗死及缺血再灌注中的研究进展

Research progress of proprotein convertase subtilisin/kexin type 9 in myocardial infarction and ischemia reperfusion

目前,前蛋白转化酶枯草杆菌蛋白酶/Kexin9型(PCSK9)抑制剂已经作为一种快速、有效降低低密度脂蛋白胆固醇(LDL-C)的药物广泛地应用在临床领域,除了可以通过调节LDL-C来影响动脉粥样硬化的进程外。临床数据表明,PCSK9在缺血心脏中上调,并且降低PCSK9的表达对梗死范围、梗死后炎症和重构以及缺血再灌注后的心功能不全存在益处。在心血管风险增加的受试者中,PCSK9抑制与心肌梗死、中风和冠状动脉血运重建的发生率降低以及内皮功能改善相关。本文综述了在心肌梗死以及心梗后的缺血再灌注中PCSK9起到的作用。

At present,proprotein convertase subtilisin/kexin type 9(PCSK9)inhibitor has been widely used in clinical field as a fast and effective drug to reduce low density lipoprotein cholesterol(LDL-C),in addition to regulating LDL-C to affect the process of atherosclerosis.Clinical data show that PCSK9 is upregulated in ischemic heart,and downregulation of PCSK9 expression can benefit infarct size,post-infarct inflammation and remodeling,and cardiac dysfunction after ischemia/reperfusion.In subjects with increased cardiovascular risk,PCSK9 inhibition was associated with reduced incidence rates of myocardial infarction,stroke,and coronary revascularization,as well as improved endothelial function.This article reviews the role of PCSK9 in myocardial infarction and ischemia-reperfusion after myocardial infarction.
