Summary

This study looks at whether wearing a fitness tracker before surgery can help predict dangerous drops in blood pressure during anesthesia in patients 65 and older. Researchers will monitor physical activity and sleep patterns with an ActiGraph device, then check for links to heart function and complications. The goal is to find a simple, noninvasive way to improve surgical safety for older adults.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: wearable accelerometer (ActiGraph)
What this could lead to: If successful, this could lead to a simple way to identify elderly patients at risk for complications during surgery, helping doctors take preventive steps.
What could go wrong: This is an early observational study with only 100 participants, so results may not apply to all patients. The device measures activity, not direct causes of complications.
