Remote Ischemic Perconditioning in Patients With ST-segment Elevation Myocardial Infarction

All patients will be prepared with an upper-arm blood pressure cuff before arterial puncture (contralateral in case of radial access). In patients allocated into PPCI plus RIPC group, the protocol will be started immediately after cuff preparation. Upper-arm will be exposed to 4 cycles of ischemia/reperfusion, each obtained by 5 min cuff inflation at 200mmHg, followed by 5 min complete deflation.

All patients randomized to PPCI only arm, the blood pressure cuff will be applied to the arm or the calf but will not be inflated.
