First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looked at whether the time of day a person has heart surgery changes how their heart muscle tolerates the stress of the procedure. Researchers took small tissue samples from the hearts of 88 patients having planned heart surgery, either in the morning or afternoon. They then tested these samples in the lab to see how much damage occurred when blood flow was temporarily stopped and then restored, mimicking what happens during surgery.
