↵* P ≤ 0.0001, CPT vs. rest for each corresponding hemodynamic parameter in QCA study evaluation.
↵† P ≤ 0.0001, CPT vs. rest for each corresponding hemodynamic parameter in PET study evaluation.
HR = heart rate; SBP = systolic blood pressure; DBP = diastolic blood pressure; RPP = systolic blood pressure × heart rate; %ΔRPP = percent change of RPP from rest during CPT; MAP = mean arterial blood pressure.
Values are mean ± SD.
