Abstract: Recently, early reperfusion therapy has become the optimal treatment for acute ST-segment elevation myocardial infarction (STEMI). One of the most effective reperfusion strategies is percutaneous coronary intervention (PCI).Depend on the time of chest pain onset, transfer mode of patients and treatment capacity of hospital, the methods of PCI are different, including primary PCI, rescue PCI and facilitated PCI. How to seize the optimal time of intervention therapy and reduce the time interval from symptom onset to reperfusion to rescue the dying myocardial cells are the key for improving prognosis, reducing mortality and decreasing major adverse cardiovascular events (MACE) of patients.
