The infrasonic recorder (IR) accurately measures blood pressure in older men with hypertension. This noninvasive device can help identify pseudo-hypertension, improving patient monitoring.

Area of Science:

  • Gerontology
  • Cardiovascular Medicine
  • Biomedical Engineering

Background:

  • Hypertension is a prevalent condition in elderly individuals.
  • Accurate blood pressure monitoring is crucial for managing hypertension and preventing complications.
  • Pseudo-hypertension can lead to undertreatment of actual hypertension.

Purpose of the Study:

  • To compare the accuracy of indirect cuff mercury sphygmomanometer and automatic infrasonic recorder (IR) measurements against direct intra-arterial diastolic blood pressure (BP) in elderly hypertensive men.
  • To evaluate the utility of the difference between cuff and IR diastolic BP in identifying pseudo-hypertension.

Main Methods:

  • Study included 36 hypertensive men aged 60 years or older.
  • Direct intra-arterial BP, indirect cuff BP, and IR BP measurements were recorded.

  • Receiver operating characteristic (ROC) curve analysis was used to assess diagnostic performance.

    • Main Results:

    • A cuff-IR diastolic BP difference of 4 mm Hg demonstrated high sensitivity (93%) and negative predictive value (93%) for identifying pseudo-hypertension.
    • The IR measurement showed high accuracy compared to intra-arterial measurements.
    • The IR device proved to be a reliable noninvasive alternative.

    Conclusions:

    • The automatic infrasonic recorder (IR) is a valid, noninvasive tool for blood pressure measurement in elderly hypertensive patients.
    • The IR may be preferable to cuff measurements for screening and monitoring due to its accuracy and ability to detect pseudo-hypertension.
    • This technology can aid in more precise hypertension management in older adults.
