Abstract

This case report details the clinical presentation, diagnosis, and multidisciplinary management of a 68-year-old man with cardiac thyrotoxicosis mimicking an acute coronary syndrome (ACS). The patient presented with persistent anginal chest pain, systemic symptoms, and electrocardiographic abnormalities suggestive of ACS. Despite presenting with persistent chest pain and ACS-like symptoms, a thorough examination, including the calculation of the thyrotoxicosis storm (StPRM) score, revealed thyrotoxicosis-induced dilated cardiomyopathy, challenging the initial diagnosis. This specific scoring for thyrotoxicosis severity played a crucial role in accurately identifying the thyrotoxic crisis. The case highlights the intricate relationship between thyroid dysfunction and cardiovascular manifestations, emphasizing the need for a multidisciplinary approach. Management included standard ACS protocols, careful titration of antithyroid medications, and the transition from intravenous to oral heart failure medications. Follow-up assessments demonstrated the success of personalized treatment strategies, with the normalization of thyroid function and complete resolution of the patient's symptoms. Nevertheless, the enduring impairment of left ventricular function following treatment prompts intriguing inquiries into the lasting impact of cardiac thyrotoxicosis on myocardial recovery. However, the persistence of impaired left ventricular function post-treatment raises intriguing questions about the lingering effects of cardiac thyrotoxicosis on myocardial recovery. This case underscores the importance of considering diverse cardiac presentations in hyperthyroid patients and the effectiveness of individualized management approaches in navigating the complexities of thyroid-cardiac interactions.
