Comparison of two noninvasive devices for measurement of central systolic blood pressure with invasive measurement during cardiac catheterization.

Recently, a new device for noninvasive assessment of central systolic blood pressure (cSBP) (BPro device with A-Pulse) was approved by the US Food and Drug Administration, but available data are limited. In 52 patients undergoing invasive elective cardiac evaluation, central hemodynamics were measured invasively. Immediately thereafter, radial artery waveforms were sampled by two noninvasive techniques, the BPro and, as a comparator, the SphygmoCor System.

Among nearly 2000 consecutive PTCA-patients 42 (36 male, six female; mean age 60 +/- 11 years) had ejection fractions < or = 35% (mean 30 +/- 5%). 34 patients suffered from unstable and eight from stable angina. All had previous myocardial infarction and of these 23 had recent myocardial infarction.
