Heart test during surgery may spot deadly risks
NCT ID NCT03365726
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving a drug called dobutamine during major non-cardiac surgery and using a special ultrasound (speckle tracking) can identify patients at higher risk of heart attack or death after surgery. The researchers enrolled 140 adults undergoing major abdominal, chest, hip, or cancer surgery. The goal was to see if this intraoperative stress test could help anesthesiologists prevent serious heart complications.

- Active substance
- dobutamine
- What this could lead to
- If successful, this approach could help doctors identify high-risk patients during surgery and take steps to prevent heart attacks or death afterward.
