Assessment

Primary outcomes

Evaluation of the extent of myocardial lethal ischemia-reperfusion injury by cardiovascular magnetic resonance imaging 7 days after acute myocardial infarction

Interventions/Control_1

H2 gas inhalation group: H2-mixed gas (H2 1.3%, O2 26%, N2 74%)
Patients who suspect that they are having an acute myocardial infarction at an emergency room start to inhale gas and continue to inhale gas during PCI procedure.

Interventions/Control_2

Control group: control gas (O2 26%, N2 74%)
Patients who suspect that they are having an acute myocardial infarction at an emergency room start to inhale gas and continue to inhale gas during PCI.
