Pericardial effusion in hypothyroidism

C A Hardisty, D R Naik, D S Munro

    Clinical Endocrinology

    Summary
    This summary is machine-generated.

    Pericardial effusions are common in untreated hypothyroidism and resolve with thyroid hormone replacement. Echocardiography can detect these effusions, which correlate with hypothyroidism severity.

    Area of Science:

    • Cardiology
    • Endocrinology
    • Medical Imaging

    Background:

    • Hypothyroidism, a condition of insufficient thyroid hormone production, can affect multiple organ systems.
    • Cardiac involvement in hypothyroidism, including pericardial effusion, is a known complication.

    Purpose of the Study:

    • To investigate the prevalence of pericardial effusion in patients with untreated hypothyroidism.
    • To assess the relationship between pericardial effusion and the severity of hypothyroidism.
    • To evaluate the resolution of pericardial effusion following thyroid hormone replacement therapy.

    Main Methods:

    • Echocardiography was used to examine 39 patients with untreated hypothyroidism for pericardial effusion.
    • Plasma creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) levels were measured.

    Related Experiment Videos

  • Nine patients were reassessed after initiating thyroxine replacement therapy.

    • Main Results:

    • Pericardial effusions were detected in 12 out of 39 patients, more frequently in those with severe hypothyroidism.
    • Elevated plasma CPK and LDH levels were associated with the presence of pericardial effusion.
    • Effusions resolved only after thyroid function normalized during thyroxine therapy.

    Conclusions:

    • Pericardial effusion is a significant finding in untreated hypothyroidism.
    • Echocardiography is a valuable tool for diagnosing pericardial effusion in hypothyroid patients.
    • Thyroid hormone replacement is essential for the resolution of hypothyroidism-associated pericardial effusions.
