Implication

Wrist devices vary substantially from aortic BP; leaves open their clinical reliability pending rigorous validation.

Key Points

  • This research aims to evaluate the accuracy of wrist oscillometric blood pressure measurement devices compared to a standard method.
  • Measured blood pressure at the aortic arch and wrist in 27 subjects during coronary angiography.
  • Performed four replicate comparative measurements for reliability.
  • Analyzed correlation coefficients and differences, applying multiple regression for diastolic pressure.
  • The BPW measured systolic pressure 1.2 mm Hg higher and diastolic pressure 4.1 mm Hg higher on average compared to standard measurement.
  • Correlation coefficients were 0.85 for systolic and 0.84 for diastolic pressures.
  • Significant variability in measurements was found, with poorer accuracy for lower diastolic values (r = 0.89, p<0.001).
