How iodine exposure from medical imaging affects thyroid health and heart risks in veterans
Official title: Iodine Excess, Thyroid Dysfunction, Cardiovascular Outcomes, and Mortality Among U.S. Veterans
Funded at VA Greater Los Angeles Healthcare System · NIH-11041433 · Data updated 2026-11-12
This study is looking at how the iodine in certain medical imaging tests might affect the thyroid and heart health of U.S. veterans, with the goal of finding out who might be at risk and how to better care for them.

Who could benefit from this research
✓Could help
Ideal candidates for this research are U.S. veterans who have undergone radiologic procedures involving iodinated contrast media.
✕Less likely to help
Patients who have not been exposed to iodinated contrast media or those without thyroid or cardiovascular concerns may not benefit from this research.
What this research studies
This research investigates the relationship between iodinated contrast media used in medical imaging and its effects on thyroid function and cardiovascular health among U.S. veterans. It aims to understand how excessive iodine exposure can lead to thyroid dysfunction, which may subsequently impact heart health. By analyzing data from the Veterans Health Administration, the study will explore the risks associated with iodine-rich substances and their potential consequences on cardiac parameters. The findings could help identify at-risk individuals and improve patient care in veterans receiving radiologic procedures.
Why it matters
Potential benefit: If successful, this research could lead to better management of thyroid health and cardiovascular risks in veterans exposed to iodinated contrast media.
How similar studies have gone: Previous research has indicated potential risks associated with iodinated contrast media, suggesting that this investigation builds on established findings rather than exploring a completely novel area.
