ABSTRACT
Objective To investigate the effect of remote ischemic preconditioning on myocardial infarction and the involved protective mechanisms. Methods Twenty-four male SD rats were randomly divided into four groups ischemia-reperfusion (I/R) group, rote ischemic preconditioning (RIPC) group, remote ischemic preconditioning + ischemia-reperfusion (RIPC+I/R) group, and RIPC+AG490+I/R group. The blood samples and myocardial specimens were collected and prepared for tests. The related enzymes were detected and the size of myocardial infarction was measured. The cardiac cells were determined by electron microscopy and light microscopy. Results The size of myocardial infarct and myocardial enzymes were significantly reduced in RIPC+I/R group compared to those in I/R group (P < 0.05). The size of myocardial infarction and myocardial enzymes were significantly increased in AG490 group compared to those in RIPC+I/R group (P < 0.05), but were significantly reduced in AG490 group compared to those in I/R group (P < 0.05). Conclusions Remote ischemic preconditioning may be effective in cardioprotection. The JAK/STAT pathway is involved in the cardioprotection of remote ischemic preconditioning.
