The goal of this observational study is to use the WHOOP device to measure heart rate variability (HRV) in patients with coronary artery disease (CAD) before and after they have CABG (coronary artery bypass graft) surgery. The main questions it aims to answer are: * 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.

Change in Heart Rate Variability (HRV) Before and After CABG Surgery
The primary goal of this study is to assess how heart rate variability (HRV) changes in patients with coronary artery disease (CAD) before and after coronary artery bypass graft (CABG) surgery.
Time frame: - Pre-operative, Up to 1 hour before surgery (Measurement taken in the pre-op area) - Post-operative, Up to 1 day after surgery - 3 days prior to ICU discharge.
Understanding correlation in HRV measurements taken immediately after surgery compared versus HRV measurements taken prior to hospital discharge.
The secondary aim of this study would be to associate this change in HRV with the patient's clinical course to establish HRV as a way to assess current patient status and to predict clinical course and outcomes.
Time frame: Two HRV measurements taken for comparison; - Post-operative, Up to 1 day after surgery - 3 days prior to ICU discharge.
