摘要
Acute ST elevation myocardial infarction, caused by the acute occlusion of a coronary artery, is a lifethreating emergency. Reperfusion therapy, namely, using the mechanical or chemical method to open the infarction related artery （IRA）, has become the key treatment for such patients. As the duration of a coronary occlusion is the main determinant of final infarct size, and the latter determines the outcome of acute myocardial infarction （AMI） patients, the time issue has long been the most important topic in reperfusion therapy. Besides the time issue, several other factors must be considered： the efficiency of the reperfusion therapy, and the availability of the reperfusion therapy.
