Aspirin is integral in the primary and secondary prevention of coronary artery disease and acute coronary syndrome. Given the high clinical importance of aspirin in the management of coronary artery disease, much attention has been directed towards the concept of "aspirin resistance." Unfortunately, the term aspirin resistance is ill-defined in the literature, leading to a large variance in the reported prevalence of this phenomenon. In this review, the current understanding of aspirin resistance is discussed. Commonly used functional and diagnostic tests of platelet function, including their strengths and weakness, are reviewed. We next discuss several proposed mechanisms of aspirin resistance and special high-risk groups at risk for aspirin treatment failure. We then discuss optimal dosing and diagnostic strategies for those populations at risk for aspirin resistance with a focus on tailored aspirin therapy for high-risk groups. Finally, future topics of interest in the field of aspirin resistance are considered.
阿司匹林在冠状动脉疾病和急性冠脉综合征的一级和二级预防中不可或缺。鉴于阿司匹林在冠状动脉疾病管理中的重要临床意义,人们对“阿司匹林抵抗”这一概念给予了高度关注。不幸的是,文献中阿司匹林抵抗的定义不明确,导致这一现象的报告发生率差异很大。在这篇综述中,讨论了目前对阿司匹林抵抗的认识。综述了血小板功能的常用功能和诊断检测方法,包括它们的优缺点。接下来,我们讨论了几种提出的阿司匹林抵抗机制和特殊的高危人群,这些人群有发生阿司匹林治疗失败的风险。然后,我们讨论了有发生阿司匹林抵抗风险的人群的最佳剂量和诊断策略,重点是针对高危人群的个体化阿司匹林治疗。最后,考虑了阿司匹林抵抗领域未来的研究课题。
