Thyrotoxicosis and the Heart – A Review of the Literature

Abstract

Thyrotoxicosis is a common endocrine disorder affecting more females than males. It is well known that one of the main complications of thyrotoxicosis is heart disease, including heart
rhythm abnormalities. Studies have clearly shown that patients with hyperthyroidism are more likely to die from heart disease or stroke, despite effective treatment. This article sets out to
review the range of possible cardiovascular complications that occur in thyrotoxicosis as well as the pathophysiological mechanisms responsible for these complications. Management of
these complications is also discussed.
