According to traditional thinking, atherosclerosis results from passive lipid deposition in the vascular wall. Thus, therapies predominantly targeted lipid metabolism. The contemporary view of atherosclerosis, however, has broadened to include an active and complex role for inflammation, orchestrated in part by mediators of the immune system. This recognition prompted the question of whether antiinflammatory interventions might provide a novel avenue for the treatment of atherosclerosis. Uncertainties about the type of antiinflammatory regimen and appropriate patient selection currently hamper clinical investigation. Yet cardiovascular scientists have begun to address these questions at the bench, in experimental models, and indirectly in humans. Inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A HMG-CoA reductase (statins) have emerged as promising tools with dual functions. Originally designed to target elevated lipids, the "traditional" cause of atherosclerosis, statins might also confer cardiovascular benefit by directly or indirectly modulating the inflammatory component of this prevalent disease. Yet controversy persists regarding the (clinical) relevance of these potential non-LDL-lowering "pleiotropic" functions of statins. This overview addresses the controversy by reviewing in vitro and in vivo evidence regarding statins as antiinflammatory agents.
按照传统观念,动脉粥样硬化是血管壁中脂质被动沉积的结果。因此,治疗主要针对脂质代谢。然而,当代对于动脉粥样硬化的看法已经拓宽,将炎症的积极且复杂的作用纳入其中,炎症部分由免疫系统的介质协调。这种认识引发了一个问题,即抗炎干预措施是否可能为动脉粥样硬化的治疗提供一条新途径。目前,关于抗炎方案的类型以及合适的患者选择的不确定性阻碍了临床研究。然而,心血管科学家已经开始在实验室、实验模型以及间接在人体中解决这些问题。3-羟基-3-甲基戊二酰辅酶A(HMG-CoA)还原酶抑制剂(他汀类药物)已成为具有双重功能的有前景的工具。他汀类药物最初设计用于针对动脉粥样硬化的“传统”病因——血脂升高,它也可能通过直接或间接调节这种常见疾病的炎症成分而带来心血管益处。然而,关于他汀类药物这些潜在的非降低低密度脂蛋白(LDL)的“多效性”功能的(临床)相关性,争议仍然存在。本综述通过回顾关于他汀类药物作为抗炎药物的体外和体内证据来探讨这一争议。
