Thyrotoxicosis, Cardiomyopathy, Congestive heart failure


Thyrotoxic cardiomyopathy is a rarely diagnosed disease in patients coming into the hospital with hyperthyroidism for the first time. The objective of this case study is to present the rare case of a patient, who was diagnosed with a thyrotoxic cardiomyopathy for the first time. A 47-year old Saudi male was presented in the King Abdulaziz Medical City in Jeddah, Saudi Arabia in March 2017, with a two-week history of progressive dyspnea, orthopnea, paroxysmal nocturnal dyspnoea, and atrial fibrillation. Following physical examinations and investigations, the diagnosis of thyrotoxicosis was performed. Initially, he was treated with Methimazole, followed by radioactive therapy, which resulted in the patient’s full recovery from cardiomyopathy through the treatment of his thyrotoxicosis.

One of the first symptoms, the manifestation of thyrotoxicosis, is thyrotoxic dilated cardiomyopathy. In most cases, it may be completely reversible through the appropriate treatment of the thyrotoxicosis.
