Too much or too little iodine.

Myxedema crisis (also called myxedema coma), the most severe form of hypothyroidism, is rare. It occurs when thyroid hormone levels get very, very low.
Hypothyroidism can affect the heart and circulatory system in several ways. Lower production of thyroid hormone slows your heart rate. Hypothyroidism also makes the arteries less elastic, and blood pressure rises in order to circulate blood around the body.
