OBJECTIVE: To describe a case of a 46-year-old @entity1 with @entity2743 and reversible @entity712 and present a comparative analysis of 23 similar cases reported in the literature. METHODS: A detailed case report is presented. In addition, a review of the pertinent literature published between 1960 and 2002 was performed to identify similar cases of @entity384 and @entity2743 and to assess the findings in these @entity1 . RESULTS: A 46-year-old @entity1 without primary @entity299 was admitted to the hospital with Graves' @entity2743 and severe @entity712 . Her left ventricular ejection fraction (LVEF) at the time of initial assessment was less than 20%, and her condition was categorized as New York Heart Association (NYHA) functional class III. Nineteen months after she was treated for @entity1378 , her LVEF was 49% and her status was NYHA class I. A severe @entity551 episode occurred when b-adrenergic blockade therapy was initiated. The group of 23 similar cases from the literature plus our currently described @entity1 had a mean age of 45 years, a male-to-female ratio of 1:1.2, @entity2743 as the principal cause, and LVEF improvement from 29% to 58%. CONCLUSION: @entity384 is an unusual manifestation of @entity1378 with unclear cause. Clinicians should be aware of this entity because it is treatable and @entity551 can occur if b-adrenergic blockade treatment is initiated.
