  1. BSA body surface area, Htc hematocrit, DB dobutamine infusion rate, HR heart rate, mBP mean blood pressure, sBP systolic blood pressure, dBP diastolic blood pressure, RPP (= sBP × HR) rate-pressure product
  2. p is related to the rest-stress comparison within each group. prest and pstress relate to group comparisons at rest and stress, respectively
