Efforts to enhance risk stratification in patients with coronary artery disease have driven the pursuit of early detection of rupture-prone plaques-before destabilization and the onset of life-threatening thrombosis-giving rise to the concept of the vulnerable plaque (VP). Invasive diagnostic modalities closely mirror histology and provide instrumental information on VP hallmarks and their prognostic significance. However, limited positive predictive value and invasive nature restrict their use for systematic screening. Noninvasive techniques offer broader application potential, but their specificity and resolution remain inferior to those of invasive techniques. A deeper understanding of the complex interplay between traditional ischemic risk factors, anatomic settings, rheological effects and systemic influences contributing to plaque evolution and rupture has refined our approach to identifying and managing VPs. Systemic therapies have been shown to counteract plaque progression and stabilize VPs by thickening the fibrous cap, decreasing atheroma and necrotic core volumes, and reducing inflammation. In parallel, the hypothesis of sealing and passivating VPs by intravascular imaging-guided preventive stenting is gaining support after the promising results of clinical trials and substantial advances in contemporary device performance and biocompatibility. Upcoming evidence will be instrumental in defining the net benefit of novel diagnostic tools and therapeutic strategies for VPs.
在冠状动脉疾病患者中加强风险分层的努力促使人们追求在易破裂斑块失稳和危及生命的血栓形成之前进行早期检测,从而产生了易损斑块(VP)的概念。侵入性诊断方法与组织学密切相似,并提供有关VP特征及其预后意义的重要信息。然而,有限的阳性预测价值和侵入性限制了它们在系统筛查中的应用。非侵入性技术具有更广泛的应用潜力,但其特异性和分辨率仍低于侵入性技术。对传统缺血性危险因素、解剖学背景、流变学效应和全身性影响之间复杂相互作用的更深入理解,这些因素共同促成斑块演变和破裂,改进了我们识别和管理VP的方法。全身治疗已被证明可通过增厚纤维帽、减小动脉粥样硬化和坏死核心体积以及减轻炎症来对抗斑块进展并稳定VP。与此同时,在临床试验取得令人鼓舞的结果以及当代设备性能和生物相容性取得重大进展之后,血管内成像引导下的预防性支架置入术封闭和钝化VP的假说正获得支持。即将出现的证据将有助于确定针对VP的新型诊断工具和治疗策略的净效益。
