DOIAbstract
Since ischemic heart disease (IHD) is a major cause of mortality and heart failure, novel therapeutic strategies are expected to improve the clinical outcomes of patients with acute myocardial infarction. Brief episodes of ischemia/reperfusion performed at the onset of reperfusion can reduce infarct size; a phenomenon termed “ischemic postconditioning.” Extensive research has determined that different autacoids (e.g., adenosine, bradykinin, opioid, etc.) and cytokines, their respective receptors, kinase signaling pathways, and mitochondrial modulation are involved in ischemic conditioning. Modification of these factors by pharmacological agents mimics the cardioprotection by ischemic postconditioning. Here, the potential mechanisms of ische...
