Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who are experiencing STEMI and can undergo primary PCI within 12 hours of symptom onset.
✕Probably not a fit
Patients who are hemodynamically unstable, have undergone thrombolytic therapy, or have a predicted survival time of less than 6 months due to non-cardiac disease may not benefit from this study.

What this trial studies
This study investigates the effectiveness of thrombus aspiration in patients experiencing ST-segment Elevation Myocardial Infarction (STEMI) with a high thrombus burden during primary percutaneous coronary intervention (PCI). It is a multicenter, open-label, randomized controlled trial where participants are assigned to receive either thrombus aspiration or standard PCI treatment. The goal is to determine if thrombus aspiration can reduce the risk of serious cardiovascular events within 180 days and stroke within 30 days after treatment.
Why it matters
Potential benefit: If successful, this approach could significantly lower the risk of severe complications for STEMI patients with high thrombus burden.
How similar studies have gone: Previous studies have shown varying results with thrombus aspiration in similar patient populations, indicating that while the approach has been tested, its efficacy in this specific context remains to be fully established.
