Pseudohypertension in the elderly.

    Summary
    This summary is machine-generated.

    Indirect blood pressure measurements can be falsely elevated, especially in older adults. Direct intra-arterial blood pressure monitoring may be necessary for accurate hypertension management in these cases.

    Area of Science:

    • Cardiovascular Medicine
    • Geriatrics
    • Clinical Measurement

    Background:

    • Hypertension diagnosis relies on accurate blood pressure measurement.
    • Elderly patients with hypertension may exhibit pseudohypertension, leading to overestimated indirect blood pressure readings.
    • Lack of target organ damage despite high indirect diastolic pressure warrants further investigation.

    Purpose of the Study:

    • To compare direct intra-arterial blood pressure with indirect measurements in hypertensive patients.
    • To investigate the prevalence of falsely elevated indirect blood pressure in elderly hypertensive individuals.
    • To assess the utility of direct blood pressure measurement in managing hypertension.

    Main Methods:

    • Direct intra-arterial blood pressure (radial artery) was measured and compared to indirect measurements using adult and thigh cuffs.

  • Mercury sphygmomanometer was used for indirect blood pressure readings.
  • The study included 24 hypertensive patients aged 62-84 and 16 hypertensive patients aged 29-59.

    • Main Results:

    • Indirect diastolic pressure was falsely elevated by ≥30 mmHg in 12/24 older adults (≥60 years) and 4/16 younger adults (<60 years).
    • Pseudohypertension was identified in 12 older adults and 5 younger adults.
    • Significant discrepancies between direct and indirect blood pressure measurements were observed, particularly in the elderly.

    Conclusions:

    • Errors in indirect blood pressure measurement are a significant clinical concern, especially in the elderly population.
    • Pseudohypertension can lead to misdiagnosis and inappropriate treatment of hypertension.
    • Direct intra-arterial blood pressure measurement offers a more accurate assessment and may be crucial for effective hypertension management in specific patient groups.
