Myopericarditis and thyroiditis: a case report.

We hypothesize that there may be an underappreciated link between hyperthyroidism and myopericarditis. Potential pathophysiological mechanisms include viral infection, autoimmunity, or changes in myocardial fat metabolism. Suggested management consists of a combination of current guidelines for the treatment of hyperthyroidism and pericardial disease, with attention to certain disease-drug interactions. Further research is required to evaluate the true incidence of hyperthyroidism-associated myopericarditis, elucidate its pathophysiology and instruct management.
