Abstract：ObjectiveTo investigate the consistency between noninvasive and invasive central arterial pressure. MethodsSixtysix patients checked by coronary angiography were enrolled in our study. Invasive catheters were used to measure invasive central arterial blood pressure(CSP) in the root of ascending aorta, including central systolic blood pressure(CSBP), central diastolic blood pressure(CDBP), and central mean arterial pressure(CMAP). The central systolic blood pressure(CSBP), diastolic blood pressure(CDBP) and mean arterial pressure(CMAP) of noninvasive central arterial pressure(NCSP) were measured simultaneously by the US DP5000A noninvasive arterial pressure monitor. ResultsThe consistency of CSBP, CDBP and CMAP between NCSP and CSP were compared using intragroup paired t test. The values of CSBP, CDBP and CMAP did not vary significantly between the two groups, without statistically significant difference(P>0.05). ConclusionNCSP proves to be consistent with CSP. NCSP can replace CSP for measuring central arterial pressure.
