Myocardial ischemia-reperfusion injury (MIRI) is a common fatal event in cardiovascular diseases. Oxidative stress, energy metabolism disorders, and inflammatory responses that occur during this process cause severe damage to myocardial cells. Ferroptosis is a novel form of cell death closely related to cellular damage in MIRI. Numerous studies have demonstrated that specific active ingredients can regulate iron homeostasis and inhibit ferroptosis, thereby protecting myocardial function and enhancing the prognosis of patients. At the same time, traditional Chinese medicine monomers also provide a new perspective for the treatment of MIRI. This review summarizes the recent advances in understanding the mechanisms underlying ferroptosis, with the aim of providing potential novel therapeutic strategies for the clinical management of MIRI.

Timely blood resupply is a clinical strategy to treat myocardial infarction, which unavoidably causes myocardial ischemia-reperfusion injury. With disturbed electrical conduction and oxidative stress in infarcted myocardium, injured heart experiences a negative ventricle remodeling process, and finally leads to heart failure. Nitric oxide (NO) is a short-lived signaling molecule regulating cardiovascular homeostasis, while vasodilation of systemic vasculature is accompanied by its exogenous supplementation.

Robinin (RB) is an accepted antioxidant herbal product with known cardio-protective activity. To explore the anti-oxidative potential of RB in treating myocardial ischemia or reperfusion (MI/RI) damage in rats after inducing hypercholesterolemia (HC). HC was induced by administering cholesterol (2%) to rats for eight weeks.

Myocardial ischemia-reperfusion injury (MIRI) endures as a substantial impediment to the management of cardiovascular disease. The pathophysiology of MIRI is complex, involving oxidative stress, calcium overload, inflammation, and apoptosis. The NRG1/ErbB4 signaling pathway has been implicated in modulating oxidative stress responses in the heart, potentially reducing cellular damage caused by free radicals.

Myocardial ischemia/reperfusion injury (MIRI) worsens ischemic damage, with ferroptosis as a key mediator of this iron-dependent cell death. Lactylation, a novel epigenetic modification, remains poorly understood in MIRI-associated ferroptosis. This study aimed to elucidate the mechanistic link between lactylation and ferroptosis in MIRI.
