The primary goal of this study is to use the WHOOP fitness band as a way to measure heart rate variability (HRV) in patients with coronary artery disease (CAD) and to establish a change in HRV before coronary artery bypass graft (CABG) surgery and during post-operative stay. The secondary aim of this study would be to associate this change in HRV with the patient’s clinical course. The validation component will test WHOOP’s HRV capabilities compared to the gold-standard Holter monitor.
