ABSTRACT

Myocardial ischemia-reperfusion injury (MIRI) remains a major complication following reperfusion therapy for acute myocardial infarction. It involves complex pathological processes including mitochondrial dysfunction, apoptosis, inflammatory cascades, and oxidative stress. Conventional pharmacological treatments are often limited by poor targeting efficiency and systemic toxicity. In contrast, nanomedicine-based delivery systems offer promising translational potential through precise targeting, microenvironment-responsive release, and multi-target synergistic regulation. This review systematically summarizes recent advances in nanotherapeutic strategies targeting mitochondria, apoptotic pathways, inflammation, and reactive oxygen species (ROS), with a focus on mechanistic insights, clinical relevance, and technical challenges. This review provides a multidimensional perspective for future research and highlights key translational barriers to clinical implementation.
