Summary

This study tests a special balloon procedure called ischemic postconditioning in 1800 people having a heart attack. After opening the blocked artery, doctors briefly inflate and deflate a balloon four times to see if it reduces heart damage. The goal is to lower the chance of heart failure or death.
