Your thyroid is a small, butterfly-shaped gland at the base of your throat. Your pituitary gland produces thyroid-stimulating hormone that messages your thyroid when to produce a hormone called T3. Some of your T3 converts to T4. Both are involved in numerous body processes. Your thyroid hormones are involved in metabolism, growth and development, your heart rate, how well you concentrate, and many other processes.

There are two main thyroid disorders: hyperthyroidism and hypothyroidism. If your thyroid gland produces more T3 than your body needs, you have hyperthyroidism. Over 4, hyperthyroid patients who underwent thyroid surgery were studied. The most common cardiovascular conditions among the hyperthyroid group were hypertension, atrial fibrillation, and heart failure.

However, the risks of coronary artery disease, stroke and death were the same between hyperthyroid patients and healthy individuals. This study shows that patients with hyperthyroidism have increased risks of certain cardiovascular conditions despite treatment with thyroid surgery, similar to the risks of those who get treated with antithyroid medications or radioactive iodine and that the risks remain high even 20 years after thyroid surgery.
