Fig. 1. Correlation between CAI and BPV changes during ECP from baseline. A: Correlation between CAI on the ipsilateral side and the percentage decrease in the HF DBP during ECP from baseline. B: Correlation between CAI on the contralateral side and the percentage decrease in TP of the SBP during ECP from baseline. C: Correlation between CAI on the contralateral side and the percentage decrease in LF/HF of the SBP during ECP from baseline. CAI: cerebral augmentation index, DBP: diastolic blood pressure, ECP: external counterpulsation, HF: high frequency, LF: low frequency, SBP: systolic blood pressure.
