title: Cellular and molecular mechanisms of endothelial ischemia/reperfusion injury: perspectives and implications for postischemic myocardial protection.
abstract: Ischemia/reperfusion (I/R) injury is a major cause of myocardial damage. Despite continuous efforts, minimizing I/R injury still represents a great challenge in standard medical treatments of ischemic heart disease, i.e., thrombolytic therapy, primary percutaneous coronary intervention, and coronary arterial bypass grafting. Development of effective interventions and strategies to prevent or reduce myocardial I/R injury is therefore of great clinical significance. Endothelial dysfunction plays a significant role in myocardial I/R injury, which renders endothelial cells an attractive target for postischemic myocardial protection. The rapidly evolving knowledge of the mechanisms of endothelial I/R injury helps broaden perspective for future development of novel strategies targeting endothelium for alleviating myocardial I/R damage. This review provides a comprehensive summary of the cellular and molecular mechanisms of endothelial I/R injury. Current perspectives and future directions for developing endothelium targeting therapeutics for postischemic myocardial protection are further discussed.
