The myocardial blood supply must be restored as soon as possible to reduce the mortality risk, however, reperfusion itself paradoxically leads to further death of cardiomyocytes and increases the infarct size; this is known as myocardial ischemia/reperfusion injury (MIRI). The pathological mechanism of MIRI is complex, and current research mainly focuses on oxidative stress, dysfunctional mitochondrial energy metabolism, Ca 2+ overload, endoplasmic reticulum stress (ERs) and the inflammatory response. This review briefly summarizes the mechanism of MIRI, and natural plant product (NPP) components proven to ameliorate MIRI and their related signaling pathways. NPPs can alleviate MIRI by regulating oxidative stress, inflammation, ERs, Ca 2+ overload and mitochondrial function maintenance. This review will deepen our understanding of how NPPs reduce MIRI and the future value of NPPs in cardio-protection.
