Longitudinal evaluation of autonomic cardiovascular tests in patients undergoing coronary artery bypass grafting surgery. Longitudinal autonomic cardiovascular evaluation (Valsalva maneuver and respiratory sinus arrhythmia) in the three groups: CABG, patients who underwent coronary artery bypass grafting; CAD, patients with coronary artery disease who did not undergo surgery; healthy, control subjects without CAD. *P < 0.05 versus CABG preoperative value; †P < 0.05 versus CABG day 3; ‡P < 0.05 versus CABG and CAD.
