This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
When you have a severe heart attack (called STEMI), doctors need to act quickly to restore blood flow to your heart. This trial is testing whether an extra step — manually removing the blood clot before placing a stent — helps prevent future complications like another heart attack, stroke, or death. Researchers want to see if thrombus aspiration improves outcomes for patients with large clots.
Some heart attack patients have very large blood clots that make their condition more dangerous. Doctors wonder whether removing the clot first, before placing the stent, might lead to better healing and fewer complications down the road.

If you join this trial, you will be randomly assigned to one of two groups: one group will receive manual clot removal before their stent is placed, and the other group will receive the stent without the clot removal step first. Both groups receive standard emergency heart attack care. The research team will track your health for 6 months after the procedure, monitoring for any complications like another heart attack, stroke, or the need for additional treatment.
