  • Values are mean (SD).

  • 3-150 p < 0.05, early v late postoperative studies.

  • 3-151 p < 0.05 v preoperative study.

  • AR, acceleration rate; AT, acceleration time; DBP, diastolic blood pressure; DR, deceleration rate; DT, deceleration time; E:A, E:A ratio; HR, heart rate; IVRT, isovolumic relaxation time; Post, two weeks postoperatively; Pre-, preoperative study; SBP, systolic blood pressure.
