Association of inadequately controlled hypothyroidism with major adverse cardiovascular events in type 2 diabetes patients receiving levothyroxine: a retrospective cohort study.

Key takeaways

Researchers looked at 12,890 adults with type 2 diabetes and found that those whose thyroid levels stayed too high (meaning their levothyroxine dose was not right) had more heart problems like heart attacks and strokes. This study shows a link between poorly controlled thyroid disease and worse heart health, but it cannot prove that fixing the thyroid would prevent those events.
