What causes hyperthyroidism cardiomyopathy?

Hyperthyroid cardiomyopathy may be related to thyroid-related diseases, pituitary adenomas, chronic diseases, etc.

1. Thyroid related diseases

If the patient has thyroid-related diseases, such as Hashimoto thyroiditis, toxic adenoma, etc., it may lead to excessive thyroid hormone secretion, rapid heart rate, and then damage cardiomyocytes, leading to hyperthyroid cardiomyopathy.

2. Pituitary adenomas

If the patient has pituitary adenomas, it may stimulate excessive thyroid hormone secretion, which may cause hyperthyroidism and lead to hyperthyroid cardiomyopathy.

3. Chronic diseases

If the patient has pernicious anemia, primary adrenal insufficiency and other chronic diseases, it may cause thyroid hormone increase, and then lead to hyperthyroid cardiomyopathy.
