Blood sugar marker may reveal hidden heart damage after attack

This study looked at 674 people who had a severe type of heart attack (STEMI) and were treated with a procedure to open blocked arteries. Researchers checked if a simple blood test called the triglyceride glucose (TyG) index could predict how much heart muscle was damaged and the risk of future problems like another heart attack or heart failure. They found that a higher TyG index was linked to more heart damage and worse outcomes, suggesting this test could help doctors identify high-risk patients.
