↵* P < 0.05 for comparison between resting and hyperemic studies on each hemodynamic measurement.
↵† P < 0.05 for comparison between H₂¹⁵O and ⁸²Rb scans on each hemodynamic measurement.
HR = heart rate (beats/min); SBP = systolic blood pressure (mm Hg); DBP = diastolic blood pressure (mm Hg); MAP = mean arterial pressure (mm Hg).
RB1 and RB2 represent ⁸²Rb studies before and after dipyridamole administration; HO1 and HO2 represent H₂¹⁵O studies. Administration of dipyridamole significantly increased heart rate and systolic blood pressure. Heart rate of HO2 was slightly lower than that of RB2.
