Simple Pre-Surgery test may spot hidden heart damage

This study tested whether a brief, low-intensity exercise test before noncardiac surgery could help doctors detect heart injury after surgery better than standard care. Ten adults aged 45 or older participated. Researchers measured heart injury using a blood test for up to three days after surgery and compared results to the exercise test findings. The goal was to see if the exercise test could predict or identify heart injury, which might help doctors reduce risks in the future.
