    The roll over test (RT) may not accurately predict gestational hypertension (GH). Many women who tested negative for GH still developed the condition, suggesting limitations in this diagnostic approach.

    Area of Science:

    • Obstetrics and Gynecology
    • Cardiovascular Physiology in Pregnancy
    • Clinical Diagnostics

    Background:

    • Gestational hypertension (GH) is a significant complication of pregnancy.
    • Early detection of GH is crucial for maternal and fetal well-being.
    • The roll over test (RT) was developed to predict the onset of GH.

    Purpose of the Study:

    • To prospectively evaluate the predictive accuracy of the roll over test (RT) for gestational hypertension (GH).
    • To assess the relationship between changes in blood pressure upon repositioning and the development of GH.

    Main Methods:

    • Eighty-five pregnant women (28-36 weeks gestation) underwent the RT.
    • Blood pressure was measured in left lateral and supine positions after a period of bed rest.

  • Patients were categorized into groups based on blood pressure changes.
  • Main Results:

    • Only 15% of patients with a positive RT developed GH.
    • 22% of patients with a negative RT subsequently developed GH.
    • A decrease in diastolic blood pressure in the supine position did not reliably predict GH.

    Conclusions:

    • The roll over test (RT) demonstrated limited predictive value for gestational hypertension (GH) in this cohort.
    • A negative RT result did not exclude the risk of developing GH.
    • Further research is needed to identify more reliable methods for predicting GH.
