Summary

This trial tests whether using a suction catheter to remove large blood clots before placing a stent improves outcomes in people having a severe heart attack (STEMI). Participants must have a large clot visible on angiography. Half receive standard stent placement alone, and half receive clot suction followed by stenting. The study uses imaging to measure how much clot remains before the stent is placed.
