Pseudohypertension, an artifactual blood pressure elevation due to noncompressible vessels, was observed in a diffuse scleroderma patient. Intra-arterial monitoring confirmed this finding, differentiating it from actual hypertension.

Area of Science:

  • Cardiology
  • Rheumatology
  • Nephrology

Background:

  • Pseudohypertension is characterized by artifactual blood pressure elevation.
  • It is associated with conditions like uremia, diabetes mellitus, and atherosclerosis.
  • Unrecognized pseudohypertension can lead to detrimental therapeutic interventions.

Observation:

  • A 65-year-old male patient with diffuse scleroderma presented with severe blood pressure readings.
  • Conventional sphygmomanometry indicated readings of at least 240/135 to 145 mm Hg.
  • Concerns arose regarding potential scleroderma renal crisis and associated treatments.

Findings:

  • Intra-arterial blood pressure measurement revealed a significantly lower reading of 107/52 mm Hg.
  • This discrepancy confirmed the presence of pseudohypertension.

  • This is the first documented instance of pseudohypertension in a patient with diffuse scleroderma.

    • Implications:

    • Accurate blood pressure assessment is crucial in patients with conditions causing noncompressible vessels.
    • Distinguishing pseudohypertension from true hypertension prevents unnecessary and potentially harmful treatments.
    • This case highlights the importance of considering pseudohypertension in scleroderma patients.
