Summary
Uncontrolled hyperthyroidism in pregnancy can cause severe heart failure and pulmonary edema. Prompt medical management before delivery effectively resolved these critical conditions in two reported cases.
Area of Science:
- Cardiology
- Endocrinology
- Obstetrics
Background:
- Hyperthyroidism is a common cause of heart failure.
- Pregnancy involves significant blood volume expansion, particularly in the third trimester.
- This expansion can worsen heart failure and lead to pulmonary edema if thyroid function is abnormal.
Observation:
- Two cases of pregnancy complicated by congestive heart failure and pulmonary edema due to hyperthyroidism are presented.
- Both patients presented in their third trimester without prior hyperthyroidism treatment during pregnancy.
- The patients experienced exacerbated heart failure symptoms due to pregnancy-induced hypervolemia.
Findings:
- Medical management of hyperthyroidism during pregnancy successfully treated heart failure and pulmonary edema.
- Symptoms of cardiac compromise were resolved prior to delivery in both cases.
- Effective control of maternal thyroid status is crucial for managing cardiovascular complications in pregnancy.
Implications:
- This case report highlights the importance of recognizing and managing hyperthyroidism in pregnant patients to prevent severe cardiac events.
- Early and appropriate medical intervention can lead to favorable outcomes for both mother and fetus.
- Clinicians should consider thyroid dysfunction in pregnant individuals presenting with heart failure symptoms, especially in the third trimester.
