AB  - BACKGROUND: Central systolic blood pressure (SBP) can be estimated by an 
      oscillometric method developed from a pulse volume plethysmography (PVP) device. 
      The present study applied this novel method to a noninvasive blood pressure 
      monitor (NBPM). METHODS: We enrolled 50 patients (37 men, age range 30-84 years) 
      referred for cardiac catheterization. Invasive right brachial and central aortic 
      pressures (using a dual-sensor pressure catheter), and noninvasive left brachial 
      SBP and diastolic blood pressure (DBP), and PVP waveform (using a customized 
      NBPM) were simultaneously recorded. Central SBP was estimated by analysis of the 
      PVP waveform calibrated to the noninvasive SBP and DBP, using both the original 
      (CSBP-O) and the newly generated (CSBP-N) regression equations. The 
      reproducibility of the invasive central SBP by CSBP-O and CSBP-N was examined 
      using the concordance correlation coefficient. RESULTS: Overall, the invasive 
      central aortic SBP ranged 86-176 with a mean of 124 +/- 21 mm Hg. The mean 
      differences between the estimated and the invasive central SBP were -1.3 +/- 6.7 mm 
      Hg for CSBP-O and 0.0 +/- 6.2 mm Hg for CSBP-N, respectively. The concordance 
      correlation coefficients for CSBP-O and CSBP-N were 0.94 (95% confidence interval 
      (CI): 0.93-0.94) and 0.95 (95% CI: 0.95-0.96), and both were significantly better 
      than that for the noninvasive brachial SBP (0.87, 0.84-0.91) indicated by 
      non-overlapping CIs. CONCLUSIONS: The PVP method for noninvasive estimation of 
      central SBP can be applied to a commonly used NBPM. Whether the NBPM-derived 
      central SBP is superior to the noninvasive brachial SBP in the prediction of 
      cardiovascular risks remains to be investigated.
