Inclusion criteria
Inclusion criteria: 1. It was consistent with acute st-segment elevation myocardial infarction and did not exceed the window period (onset to admission to the catheterization room <12 hours); 2. Coronary angiography TIMI flow level 0-1; 3. Agree and sign the informed consent.
Exclusion criteria
Exclusion criteria: 1. Patients with acute st-segment elevation myocardial infarction, but beyond the window period, accompanied by cardiogenic shock, third-degree atrioventricular block and other emergency PCI; 2. Acute non-st elevation myocardial infarction; 3. Chronic coronary artery occlusion; 4. It was consistent with acute st-segment elevation myocardial infarction, but the blood flow of coronary angiography TIMI was grade 2 or above; 5. PCI after thrombolytic failure; 6. There was no blood flow after the balloon first passed; 7. It is difficult for the balloon to pass through, and only by tunneling the balloon can it pass through; 8. Acute occlusion of the left main; 9. The thrombus is difficult to extract, and the catheter needs extention catheter to extract the thrombus.
