| Outline of Final Research Achievements |
The first acute myocardial infarction ｐatients were randomly assigned to the control group and the hybrid-conditioning group. In the hybrid-conditioning group, three cycles of remote preconditioning were repeated, with the lower limb being pressurized for 5 minutes and depressurized for 5 minutes. After remote preconditioning, postconditioning was performed 4 cycles of 60s balloon inflation and 30s deflation, and finally the appropriate sized stent was placed. In both groups, blood was collected over time with time before and after reperfusion treatment, and the expression level of HSP72 in the separated leukocytes was quantitatively evaluated. Hybrid-conditioning method was shown to increase the expression of HSP 72, resulting in suppression of reperfusion injury.
