Answer

Hypothyroidism, hyperthyroidism, and thyroid hormone toxicity are all problems to be considered in the differential diagnosis of cardiomyopathy. For example, thyrotoxicosis is associated with a high-output state that may predispose to dilated cardiomyopathy. Results of thyroid function tests are not usually available to assist in decision making in the ED but may be sent for convenience.
