Summary
Iodine-containing contrast agents used in coronary angiography can trigger thyroid dysfunction, including thyrotoxicosis and hypothyroidism, especially in patients with pre-existing thyroid issues in iodine-deficient regions.
Area of Science:
- Endocrinology
- Radiology
- Cardiology
Context:
- Assesses the impact of iodine-containing contrast agents on thyroid function.
- Focuses on patients residing in areas with borderline iodine deficiency.
- Investigates a cohort of 146 patients undergoing coronary angiography.
Purpose:
- To determine the frequency of thyroid gland functional disturbances post-coronary angiography.
- To identify risk factors for developing iodine-induced thyroid states.
Summary:
- Thyroid pathology was prevalent at baseline (39%).
- New cases of thyrotoxicosis and hypothyroidism, and worsening of existing conditions, were observed within one month after angiography.
- Patients with pre-existing thyroid conditions are at higher risk.
Impact:
- Highlights the need for risk stratification and monitoring of thyroid function in patients undergoing procedures with iodine contrast.
- Informs clinical practice regarding the management of patients with borderline iodine deficiency and pre-existing thyroid disease.
- Contributes to understanding contrast-induced thyroid dysfunction.
