Notwithstanding the effectiveness of lowering LDL cholesterol, residual CVD risk remains in high-risk populations, including patients with diabetes, likely contributed to by non-LDL lipid abnormalities. In this Perspectives in Diabetes article, we emphasize that changing demographics and lifestyles over the past few decades have resulted in an epidemic of the "atherogenic dyslipidemia complex," the main features of which include hypertriglyceridemia, low HDL cholesterol levels, qualitative changes in LDL particles, accumulation of remnant lipoproteins, and postprandial hyperlipidemia. We briefly review the underlying pathophysiology of this form of dyslipidemia, in particular its association with insulin resistance, obesity, and type 2 diabetes, and the marked atherogenicity of this condition. We explain the failure of existing classes of therapeutic agents such as fibrates, niacin, and cholesteryl ester transfer protein inhibitors that are known to modify components of the atherogenic dyslipidemia complex. Finally, we discuss targeted repurposing of existing therapies and review promising new therapeutic strategies to modify the atherogenic dyslipidemia complex. We postulate that targeting the central abnormality of the atherogenic dyslipidemia complex, the elevation of triglyceride-rich lipoprotein particles, represents a new frontier in CVD prevention and is likely to prove the most effective strategy in correcting most aspects of the atherogenic dyslipidemia complex, thereby preventing CVD events.
尽管降低低密度脂蛋白胆固醇有效,但包括糖尿病患者在内的高危人群仍存在残余心血管疾病风险,这可能是由非低密度脂蛋白脂质异常所致。在这篇糖尿病视角文章中,我们强调,过去几十年人口结构和生活方式的变化导致了“致动脉粥样硬化血脂异常综合征”的流行,其主要特征包括高甘油三酯血症、低高密度脂蛋白胆固醇水平、低密度脂蛋白颗粒的质性改变、残余脂蛋白的蓄积以及餐后高脂血症。我们简要回顾这种血脂异常形式的潜在病理生理学,特别是其与胰岛素抵抗、肥胖和2型糖尿病的关联,以及这种病症显著的致动脉粥样硬化性。我们解释了已知可改变致动脉粥样硬化血脂异常综合征成分的现有治疗药物类别(如贝特类、烟酸和胆固醇酯转运蛋白抑制剂)为何无效。最后,我们讨论现有疗法的靶向重新利用,并回顾有前景的新治疗策略以改变致动脉粥样硬化血脂异常综合征。我们推测,针对致动脉粥样硬化血脂异常综合征的核心异常,即富含甘油三酯脂蛋白颗粒的升高,代表了心血管疾病预防的新前沿,并且可能被证明是纠正致动脉粥样硬化血脂异常综合征大多数方面从而预防心血管疾病事件的最有效策略。
