Heart attack study tests simple procedure to limit damage

This study looked at whether a technique called postconditioning, done during angioplasty to reopen blocked heart arteries, can reduce damage to the heart muscle. 44 adults having their first heart attack took part. The researchers used MRI scans to measure the area of blocked small blood vessels and the overall size of the heart attack. The goal was to see if this technique could improve blood flow and limit heart injury.
