Cooling the heart during a heart attack: a trial that never got started
NCT ID NCT03361995
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study planned to test whether cooling the body before and after opening a blocked artery could help people having a heart attack. It was designed to include 80 patients at up to 15 hospitals. However, the trial was withdrawn before anyone was enrolled, so we have no information on whether cooling is helpful or safe.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Cooling procedure using the ZOLL Thermogard XP3 IVTM System
What this could lead to
If it had worked, cooling might have reduced heart damage during a heart attack, potentially improving recovery.
What could go wrong
The trial was withdrawn before any patients were enrolled, so we have no data on whether cooling is safe or effective. Cooling also carries risks like shivering, infection, or heart rhythm problems.
