This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing the best timing for opening blocked arteries in people who have had a heart attack and have multiple blockages in their heart. When a patient has a heart attack, doctors use a catheter (a thin tube) to open the main blocked artery causing the attack. This study compares two strategies: opening all other blocked arteries immediately during the same procedure, or waiting until the next day to open them.
Many patients who have a heart attack actually have blockages in multiple arteries, which can lead to worse outcomes. Guidelines recommend opening all blockages, but doctors aren't sure whether it's safer and more effective to do this right away or to wait a day or two. This trial will help answer that important question.

You will first have a catheter procedure to open the main artery that caused your heart attack. Then you'll be randomly assigned to one of two groups: one group will have the other blocked arteries opened immediately during the same procedure, while the other group will wait until the next day (while still in the hospital) to have those arteries opened. Your doctors will use a special measurement called FFR to decide which smaller blockages truly need to be opened. You'll be monitored during your hospital stay and followed up afterward to see how well each timing strategy works.
