Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Can changes in HRV, measured by the WHOOP device, help predict how well patients with CAD will recover after CABG surgery?
* Can HRV changes during the hospital stay give doctors useful information about the patient's recovery?
Participants will:
* Wear the WHOOP device before and after their CABG surgery to measure HRV.
* Share their health information to help researchers see how changes in HRV are connected to recovery.
This study will help find out if the WHOOP device can be used as a medical tool to track recovery in patients with CAD after CABG surgery.
