Pericardial effusion is rare in early hypothyroidism, occurring in only 3-6% of patients. This contrasts with older studies, as modern diagnosis detects milder thyroid disease before effusions develop.

Area of Science:

  • Endocrinology
  • Cardiology

Background:

  • Previous studies reported high incidence of pericardial effusion in hypothyroidism (30-80%).
  • These studies diagnosed hypothyroidism based on severe clinical features, not early or asymptomatic stages.
  • Modern thyroid function testing allows earlier diagnosis, potentially altering effusion prevalence.

Purpose of the Study:

  • To reassess the incidence of pericardial effusion in contemporary patients with hypothyroidism.
  • To investigate the relationship between hypothyroidism severity and pericardial effusion.

Main Methods:

  • Echocardiography was used to evaluate 30 subjects with hypothyroidism.
  • Pericardial effusion was assessed and correlated with disease severity and thyroid status.

Main Results:

  • Only two subjects (3-6%) demonstrated pericardial effusion.
  • One case of effusion in severe hypothyroidism resolved upon achieving a euthyroid state.
  • The incidence is significantly lower than previously reported.

Conclusions:

  • Pericardial effusion is a rare finding in early or mild hypothyroidism.
  • The occurrence of pericardial effusion is strongly dependent on the severity of hypothyroidism.
  • Timely diagnosis of hypothyroidism reduces the likelihood of developing pericardial effusion.
