Treatment-Induced Hypothyroidism Reduces Long-Term Post-Treatment Cardiovascular Morbidity and Mortality in Graves’ Disease and Toxic Multinodular Goiter

key information

source: Clinical Thyroidology

year: 2018


Hyperthyroidism is caused when the thyroid is overactive and produces too high of levels of thyroid hormones. The two most common causes of hyperthyroidism are Graves’ disease and toxic multinodular goiter. Antithyroid drugs, radioactive iodine therapy and surgery are all used to treat hyperthyroidism.

Thyroid hormones have major effects on the heart and palpitations and irregular heart rhythms are frequent symptoms caused by hyperthyroidism. Because of this, hyperthyroidism is associated with increased cardiac problems and can lead to death related to heart disease. This study examines the effect of radioactive iodine therapy and surgery on long-term heart disease outcomes in patients with Graves’ disease and toxic multinodular goiter and the relationship of these outcomes to post-treatment thyroid status.
