Osler's maneuver and pseudohypertension.

    The New England Journal of Medicine

    Summary

    Osler's maneuver, a bedside test, distinguishes true hypertension from pseudohypertension caused by stiff arteries. This simple method aids in accurate blood pressure assessment in elderly patients.

    Area of Science:

    • Cardiology
    • Geriatrics
    • Vascular Medicine

    Background:

    • Elevated blood pressure readings in the elderly may be falsely high due to arterial stiffening (pseudohypertension).
    • Accurate differentiation between true hypertension and pseudohypertension is crucial for appropriate patient management.

    Purpose of the Study:

    • To introduce and validate Osler's maneuver, a novel bedside procedure.
    • To differentiate between true hypertension and pseudohypertension in elderly patients.

    Main Methods:

    • Osler's maneuver involves assessing radial or brachial artery palpability distal to occlusion.
    • 24 elderly hypertensive patients were classified as Osler-positive (pseudohypertension) or Osler-negative (true hypertension).
    • Intraarterial pressure, arterial compliance, and systemic hemodynamics were measured.

    Main Results:

    • Osler-positive patients exhibited falsely elevated cuff blood pressure readings (10-54 mm Hg difference).
    • Lower arterial compliance was observed in Osler-positive subjects.
    • Reduced arterial compliance correlated with the degree of pseudohypertension.

    Conclusions:

    • Osler's maneuver effectively identifies pseudohypertension in the elderly.
    • Pseudohypertension is linked to decreased arterial compliance and increased large artery sclerosis.
    • This maneuver improves diagnostic accuracy for hypertension in older adults.
