PCSK9 plays a critical role in cholesterol metabolism via the PCSK9–LDLR axis. Liver-derived, circulating PCSK9 has become a novel drug target in lipid-lowering therapy. Accumulative evidence supports the possible association between PCSK9 and cardiac diseases and their risk factors. PCSK9 exerts various effects in the heart independently of LDL-cholesterol regulation. Acute myocardial infarction (AMI) induces local and systemic inflammation and reactive oxygen species generation, resulting in increased PCSK9 expression in hepatocytes and cardiomyocytes. PCSK9 upregulation promotes excessive autophagy and apoptosis in cardiomyocytes, thereby contributing to cardiac insufficiency. PCSK9 might also participate in the pathophysiology of heart failure by regulating fatty acid metabolism and cardiomyocyte contractility. It also promotes platelet activation and coagulation in patients with atrial fibrillation. PCSK9 is an independent predictor of aortic valve calcification and accelerates calcific aortic valve disease by regulating lipoprotein(a) catabolism. Accordingly, the use of PCSK9 inhibitors significantly reduced infarct sizes and arrhythmia and improves cardiac contractile function in a rat model of AMI. Circulating PCSK9 levels are positively correlated with age, diabetes mellitus, obesity, and hypertension. Here, we reviewed recent clinical and experimental studies exploring the association between PCSK9, cardiac diseases, and their related risk factors and aiming to identify possible underlying mechanisms.

PCSK9:与心脏病及其危险因素有关?

PCSK9 通过 PCSK9-LDLR 轴在胆固醇代谢中发挥关键作用。肝脏来源的循环 PCSK9 已成为降脂治疗的新药物靶点。越来越多的证据支持 PCSK9 与心脏病及其危险因素之间可能存在关联。PCSK9 在心脏中发挥各种作用,与 LDL-胆固醇调节无关。急性心肌梗死 (AMI) 会诱导局部和全身炎症以及活性氧的产生,导致肝细胞和心肌细胞中 PCSK9 的表达增加。PCSK9 上调促进心肌细胞过度自噬和凋亡,从而导致心功能不全。PCSK9 还可能通过调节脂肪酸代谢和心肌细胞收缩力参与心力衰竭的病理生理学。它还促进心房颤动患者的血小板活化和凝血。PCSK9 是主动脉瓣钙化的独立预测因子,并通过调节脂蛋白 (a) 分解代谢加速钙化性主动脉瓣疾病。因此,在 AMI 大鼠模型中,PCSK9 抑制剂的使用显着减少了梗死面积和心律失常,并改善了心脏收缩功能。循环 PCSK9 水平与年龄、糖尿病、肥胖和高血压呈正相关。在这里,我们回顾了最近的临床和实验研究,探讨了 PCSK9、心脏病及其相关危险因素之间的关联,旨在确定可能的潜在机制。PCSK9 是主动脉瓣钙化的独立预测因子,并通过调节脂蛋白 (a) 分解代谢加速钙化性主动脉瓣疾病。因此,在 AMI 大鼠模型中,PCSK9 抑制剂的使用显着减少了梗死面积和心律失常,并改善了心脏收缩功能。循环 PCSK9 水平与年龄、糖尿病、肥胖和高血压呈正相关。在这里,我们回顾了最近的临床和实验研究,探讨了 PCSK9、心脏病及其相关危险因素之间的关联,旨在确定可能的潜在机制。PCSK9 是主动脉瓣钙化的独立预测因子,并通过调节脂蛋白 (a) 分解代谢加速钙化性主动脉瓣疾病。因此,在 AMI 大鼠模型中,PCSK9 抑制剂的使用显着减少了梗死面积和心律失常,并改善了心脏收缩功能。循环 PCSK9 水平与年龄、糖尿病、肥胖和高血压呈正相关。在这里,我们回顾了最近的临床和实验研究,探讨了 PCSK9、心脏病及其相关危险因素之间的关联,旨在确定可能的潜在机制。循环 PCSK9 水平与年龄、糖尿病、肥胖和高血压呈正相关。在这里,我们回顾了最近的临床和实验研究,探讨了 PCSK9、心脏病及其相关危险因素之间的关联,旨在确定可能的潜在机制。循环 PCSK9 水平与年龄、糖尿病、肥胖和高血压呈正相关。在这里,我们回顾了最近的临床和实验研究,探讨了 PCSK9、心脏病及其相关危险因素之间的关联,旨在确定可能的潜在机制。
