IODINE AND THE HEART

Iodine deficiency can have deleterious effects on the cardiovascular system.  Thus, a higher iodine intake may benefit cardiovascular function.

In recent years, sodium restriction has been promoted as a means of reducing hypertension and the risk of cardiovascular disease.

Since iodized salt is the primary source of iodine for many people, iodine deficiency has become much more common in developed countries, especially among the elderly and others who are restricting salt intake.

Adequate iodine is necessary for proper thyroid function.  The heart is a target organ for thyroid hormones.  Marked changes occur in cardiac function in patients with hypo- or hyperthyroidism.

Cann considers the role iodine deficiency plays in the etiology of cardiovascular disease.

West discusses iodine and heart arrhythmia, especially atrial fibrillation.

Kahaly and Danzi discuss thyroid hormone action in the heart.
