After experiencing an acute coronary syndrome (ACS), patients are at a high risk of suffering from recurrent ischaemic cardiovascular events, especially in the very early phase. Low density lipoprotein-cholesterol (LDL-C) is causally involved in atherosclerosis and a clear, monotonic relationship between pharmacologic LDL-C lowering and a reduction in cardiovascular events post-ACS has been shown, a concept termed 'the lower, the better'. Current ESC guidelines suggest an LDL-C guided, step-wise initiation and escalation of lipid-lowering therapy (LLT). Observational studies consistently show low rates of guideline-recommended LLT adaptions and concomitant low rates of LDL-C target goal achievement, leaving patients at residual risk, especially in the vulnerable post-ACS phase. In addition to the well-established 'the lower, the better' approach, a 'strike early and strike strong' approach in the early post-ACS phase with upfront initiation of a combined lipid-lowering approach using high-intensity statins and ezetimibe seems reasonable. We discuss the rationale, clinical trial evidence and experience for such an approach and highlight existing knowledge gaps. In addition, the concept of acute initiation of PCSK9 inhibition in the early phase is reviewed. Ultimately, we focus on hurdles and solutions to provide high-quality, evidence-based follow-up care in post-ACS patients.
急性冠状动脉综合征(ACS)后,患者发生复发性缺血性心血管事件的风险很高,尤其是在极早期。低密度脂蛋白胆固醇(LDL-C)与动脉粥样硬化有关,临床研究已明确显示,药物降低 LDL-C 与 ACS 后心血管事件减少之间存在明确的、单调的关系,这一概念被称为“越低越好”。目前的 ESC 指南建议根据 LDL-C 水平,逐步启动和调整降脂治疗(LLT)。观察性研究一致显示,指南推荐的 LLT 调整和 LDL-C 目标达标率均较低,这使患者仍处于残余风险中,尤其是在 ACS 后易损期。除了已确立的“越低越好”方法外,在 ACS 早期采用起始时即联合使用高强度他汀类药物和依折麦布的联合降脂方法进行“早期强化治疗”似乎也是合理的。我们将讨论这种方法的原理、临床试验证据和经验,并强调现有的知识空白。此外,还回顾了早期开始应用 PCSK9 抑制剂的概念。最终,我们将重点关注在 ACS 患者中提供高质量、基于证据的随访护理的障碍和解决方案。
