BACKGROUND: Statins remain foundational in the prevention and treatment of atherosclerotic cardiovascular disease (ASCVD). However, despite optimal statin therapy, a significant residual risk of ASCVD persists, highlighting the need for novel lipid-lowering strategies targeting both low-density lipoprotein cholesterol (LDL-C) and other atherogenic lipoproteins. Over the last decade, a new generation of pharmacological agents has been developed to enhance dyslipidemia management beyond traditional statins. MAIN BODY: Bempedoic acid, a prodrug activated in the liver, inhibits ATP-citrate lyase (ACLY), an enzyme upstream of HMG-CoA reductase in the cholesterol synthesis pathway. This action reduces hepatic cholesterol synthesis and simultaneously upregulates LDL receptor expression, promoting enhanced LDL-C clearance. These dual actions provide a statin-independent approach to LDL-C reduction, particularly beneficial for patients with statin intolerance. In addition, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, including monoclonal antibodies and siRNA-based therapies, have shown robust LDL-C-lowering effects by preventing LDL receptor degradation, leading to a significant reduction in cardiovascular risk. Other innovative lipid-modifying approaches include antisense oligonucleotides targeting apolipoprotein C3, angiopoietin-like protein 3, and lipoprotein(a) [Lp(a)]-such as pelacarsen and olpasiran-which demonstrate promising results in addressing genetically driven dyslipidemias. Additionally, strategies aimed at enhancing apolipoprotein A1 and promoting high-density lipoprotein functionality are under investigation, although clinical validation remains ongoing. CONCLUSION: This review underscores the evolving landscape of lipid-lowering therapies, with emphasis on agents acting through novel mechanisms beyond statin pathways. Bempedoic acid, by inhibiting ACLY and increasing LDL receptor expression, represents a safe and effective option for reducing LDL-C, especially in statin-intolerant individuals. PCSK9 inhibitors further expand therapeutic options by augmenting LDL receptor recycling and clearance. The integration of these agents into clinical practice may help mitigate residual cardiovascular risk and personalize treatment strategies in dyslipidemia management.
背景:他汀类药物仍然是动脉粥样硬化性心血管疾病(ASCVD)预防和治疗的基础。然而,尽管进行了最佳的他汀类药物治疗,ASCVD的显著残余风险仍然存在,这突出表明需要针对低密度脂蛋白胆固醇(LDL-C)和其他致动脉粥样硬化脂蛋白的新型降脂策略。在过去十年中,已经开发出新一代的药物制剂,以加强传统他汀类药物以外的血脂异常管理。 主体:贝派地酸是一种在肝脏中被激活的前体药物,它抑制ATP-柠檬酸裂解酶(ACLY),这是胆固醇合成途径中HMG-CoA还原酶上游的一种酶。这种作用减少肝脏胆固醇合成,同时上调LDL受体表达,促进LDL-C清除增强。这些双重作用提供了一种不依赖他汀类药物的降低LDL-C的方法,对他汀类药物不耐受的患者特别有益。此外,前蛋白转化酶枯草杆菌蛋白酶/kexin 9型(PCSK9)抑制剂,包括单克隆抗体和基于siRNA的疗法,通过防止LDL受体降解,显示出强大的降低LDL-C的作用,导致心血管风险显著降低。其他创新的脂质修饰方法包括靶向载脂蛋白C3、血管生成素样蛋白3和脂蛋白(a)[Lp(a)]的反义寡核苷酸,如pelacarsen和olpasiran,它们在解决遗传性驱动的血脂异常方面显示出有希望的结果。此外,旨在增强载脂蛋白A1和促进高密度脂蛋白功能的策略正在研究中,尽管临床验证仍在进行。 结论:本综述强调了降脂治疗的不断演变,重点是通过他汀类药物途径以外的新机制起作用的药物。贝派地酸通过抑制ACLY和增加LDL受体表达,是降低LDL-C的一种安全有效的选择,特别是在他汀类药物不耐受的个体中。PCSK9抑制剂通过增强LDL受体再循环和清除进一步扩大了治疗选择。将这些药物整合到临床实践中可能有助于减轻残余心血管风险,并使血脂异常管理中的治疗策略个性化。
