Summary

This is a prospective, multicenter, open-label, randomized, controlled, parallel group study, in which ST-segment Elevation Myocardial Infarction (STEMI) patients with high thrombus burden(TIMI thrombus grade ≥3) are included. Patients are randomized to be treated with or without manual thrombus aspiration(TA) during primary percutaneous coronary intervention(PPCI) by a ratio of 1:1.
