Abstract
A middle-aged female patient was admitted to our medical ward with the complaints suggestive of congestive heart failure. Her history revealed that she was diagnosed as having thyroid disease about 6 years back, but the patient did not use any medication despite medical advice. Now, she is having small goiter and moderate proptosis. Investigations showed increased thyroid hormone levels with suppressed thyroid stimulating hormone levels. Immunological assay showed increased thyroperoxidase antibodies. Nuclear uptake study confirmed increased diffuse uptake of technetium-99m. Echocardiogram showed dilatation of all chambers of the heart with increased ejection fraction. Pathophysiology, clinical features, and management of Graves' disease, in particular hyperthyroidism induced high out-put failure are discussed and literature is reviewed.
