    Cardiac microvascular endothelial cells (CMECs) are crucial for maintaining microvascular integrity and are vulnerable during ischemia-reperfusion injury.

  • 2

    Dysregulated iron handling during reperfusion increases the labile iron pool, leading to ferroptosis and exacerbating microvascular injury.

  • 3

    Ferroptosis in CMECs is linked to lipid peroxidation, mitochondrial damage, and impaired endothelial function, contributing to microvascular obstruction.

  • 4

    Therapeutic strategies targeting iron chelation and antioxidant systems may improve microvascular reperfusion and clinical outcomes after myocardial ischemia.

  • 5

    Understanding the mechanisms of CMEC ferroptosis is essential for developing interventions to mitigate microcirculatory dysfunction post-reperfusion.
